RESUMO

Since we aim to test new options to find medication for cognitive disorders, we have begun to assess the effect of semaglutide and to conduct a review gathering studies that have attempted this purpose. This systematic review focuses on the cognitive effects of semaglutide, a glucagon-like peptide 1 receptor agonist (GLP-1 RA), in the context of neurological and cognitive impairment. Semaglutide, a synthetic GLP-1 analog, showcased neuroprotective effects beyond metabolic regulation. It mitigated apoptosis and improved cognitive dysfunction in cerebrovascular disease, suggesting broader implications for neurological well-being. Also, studies highlighted GLP-1 RAs' positive impact on olfactory function in obese individuals with type 2 diabetes, on neurodegenerative disorders, multiple sclerosis, and endotoxemia. In order to analyze current studies that assess the impact of semaglutide on cognitive function, a literature search was conducted up to February 2024 on two online databases, MEDLINE (via PubMed) and Web of Science Core Collection, as well as various websites. Fifteen studies on mice populations and two studies on cell lines were included, analyzed, and assessed with bias-specific tools. The neuroprotective and anti-apoptotic properties of GLP-1 and its analogs were emphasized, with animal models and cell line studies demonstrating enhanced cognitive function. While promising, limitations include fewer studies, highlighting the need for extensive research, particularly in the human population. Even though this medication seems promising, there are significant limitations, one of which is the lack of studies on human subjects. Therefore, this review aims to gather current evidence.

RESUMO

BACKGROUND: Palliative radiotherapy plays a crucial role in managing symptomatic gynecological cancers (GCs). This article aims to systematically review literature studies on palliative pelvic radiotherapy in cervical, endometrial, ovarian, vaginal, and vulvar cancers. The primary focus is centered around evaluating symptom relief, quality of life (QOL), and toxicity in order to ascertain optimal radiotherapy regimens. METHODOLOGY: For this thorough review, we mainly relied on Medline to gather papers published until November 2023. Selected studies specifically detailed symptomatology and QOL responses in palliative pelvic radiotherapy used for GCs. RESULTS: Thirty-one studies, mostly retrospective studies and those lacking standardized outcome measures, showed varied responses. Encouraging outcomes were noted in managing hemorrhage (55%) and pain control (70%). However, comprehensively assessing overall symptom response rates and toxicity remained challenging. Investigations into 10 Gy fractionation revealed benefits in addressing tumor-related bleeding and pain in female genital tract cancers. CONCLUSIONS: Palliative pelvic radiotherapy effectively manages symptomatic GCs. Nonetheless, unresolved dosing and fractionation considerations warrant further investigation. Embracing modern therapies alongside radiotherapy offers improved symptom control, emphasizing the importance of selecting suitable patients for successful GC palliation interventions.

RESUMO

(1) Background: Surgical-oncological treatment methods are continuously put to the test in times of evidence-based medicine-notably, a constant reevaluation remains key, especially for tumor entities with increasing incidence such as vulvar carcinoma. (2) Methods: In order to determine the postoperative clinical course of different methods of vulvar excision (vulvectomy, hemivulvectomy) as well as inguinal lymph node removal (lymphadenectomy, sentinel lymph node biopsy) with regard to postoperative wound-healingprocess, perioperative hemorrhage, and re-resection rates, we retrospectively analyzed surgical, morphological and laboratory data of 76 patients with a pathological diagnosed vulvar cancer. (3) Results: Analysis of our data from a single center revealed a comparable perioperative clinical course regardless of the chosen method of vulvar excision and inguinal lymph node removal. (4) Conclusions: Thus, our results emphasize the current multimodality in surgical therapy of vulvar carcinoma, in which consideration of known prognostic factors together with the individual patient's clinical situation allow guideline-based therapy aimed at maximizing surgical safety.

RESUMO

Background and Objectives: The main cause of morbidity and mortality in hemodialysis patients is cardiovascular disease, which is quite common. The main objective of our study was to investigate the relationship between oxidative stress, inflammation, and vascular and valvular calcifications in hemodialysis patients. Materials and Methods: This observational study had 54 hemodialysis patients, with an average age of 60.46 ± 13.18 years. Cardiovascular ultrasound was used to detect and/or measure aortic and mitral valve calcifications, carotid and femoral atheroma plaques, and common carotid intima-media thickness. The aortic calcification score was determined using a lateral abdomen plain radiograph. The inflammatory, oxidative, metabolic, and dietary statuses, as well as demographic characteristics, were identified. Results: There were significant correlations between the levels of IL-6 and carotid plaque number (p = 0.003), fibrinogen level and aortic valve calcifications (p = 0.05), intima-media thickness (p = 0.0007), carotid plaque number (p = 0.035), femoral plaque number (p = 0.00014), and aortic calcifications score (p = 0.0079). Aortic annulus calcifications (p = 0.03) and intima-media thickness (p = 0.038) were adversely linked with TNF-α. Nutrition parameters were negatively correlated with atherosclerosis markers: number of carotid plaques with albumin (p = 0.013), body mass index (p = 0.039), and triglycerides (p = 0.021); number of femoral plaques with phosphorus (0.013), aortic calcifications score with albumin (p = 0.051), intima-media thickness with LDL-cholesterol (p = 0.042). Age and the quantity of carotid plaques, femoral plaques, and aortic calcifications were linked with each other (p = 0.0022, 0.00011, and 0.036, respectively). Aortic annulus calcifications (p = 0.011), aortic valve calcifications (p = 0.023), and mitral valve calcifications (p = 0.018) were all associated with an increased risk of death. Conclusions: Imaging measures of atherosclerosis are adversely connected with dietary status and positively correlated with markers of inflammation and risk of mortality.

RESUMO

INTRODUCTION: Nowadays chemotherapy in breast cancer patients is optionally applied neoadjuvant, which allows for testing of tumor response to the chemotherapeutical treatment in vivo, as well as allowing a greater number of patients to benefit from a subsequent breast-conserving surgery. MATERIAL AND METHODS: We compared breast ultrasonography, mammography, and clinical examination (palpation) results with postoperative histopathological findings after neoadjuvant chemotherapy, aiming to determine the most accurate prediction of complete remission and tumor-free resection margins. To this end, clinical and imaging data of 184 patients (193 tumors) with confirmed diagnosis of breast cancer and neoadjuvant therapy were analyzed. RESULTS: After chemotherapy, tumors could be assessed by palpation in 91.7%, by sonography in 99.5%, and by mammography in 84.5% (chi-square p < 0.0001) of cases. Although mammography proved more accurate in estimating the exact neoadjuvant tumor size than breast sonography in total numbers (136/163 (83.44%) vs. 142/192 (73.96%), n.s.), 29 tumors could be assessed solely by means of breast sonography. A sonographic measurement was feasible in 192 cases (99.48%) post-chemotherapy and in all cases prior to chemotherapy. CONCLUSIONS: We determined a superiority of mammography and breast sonography over clinical palpation in predicting neoadjuvant tumor size. However, neither examination method can predict either pCR or tumor margins with high confidence.

RESUMO

We present the case of a 46 year old female patient, with a personal history of breast abscess and total thyroidectomy for multiple thyroid cysts, who was investigated in a different healthcare facility for loss of appetite and weight loss. She was referred to our hospital with a suspicion of stage IIIC ovarian cancer, based on the paraclinical investigations which were made: a pelvic MRI (magnetic resonance imaging) and the ROMA score (23,16%). The colonoscopy done at the Clinical Emergency Hospital of Bucharest after admitting the patient revealed a circumferential tumor with an ulcerative and infiltrative aspect, which occupied in totality the lumen of the colon, near the splenic flexure. Biopsies were taken at this level. The histopathology result describes a welldifferentiated colorectal adenocarcinoma. A surgical intervention with complete cytoreduction was performed. Immunohistochemistry and histopathology reports of the tissue provided confirmed the origin of the tumor as being colonic, concluding that the primary tumor was a colonic mucinous adenocarcinoma with multiple peritoneal and bilateral ovarian metastases.

RESUMO

Endometrial cancer affects the uterus and is becoming increasingly common and deadly. Although surgery and adjuvant pelvic radiotherapy can often cure the disease when it is contained in the uterus, patients with metastatic or recurrent disease have limited response rates to chemotherapy, targeted agents, and hormonal therapy. To address this unmet clinical need, innovative treatment strategies are needed, and a growing focus on the immunomodulation of the tumor microenvironment has arisen. Current data suggest that active and/or passive immunotherapy may be promising for the treatment of endometrial cancer.

RESUMO

Background: Colorectal cancer is a serious illness, with rectal cancer accounting for thirty percent of all cases. For patients diagnosed with rectal cancer, neoadjuvant downstaging chemoradiotherapy is often necessary due to advanced disease at presentation. However, for certain patients, neoadjuvant chemotherapy can result in a complete response, leading to the possibility of overtreatment during subsequent definitive surgery. Methods: In order to identify predictors for clinical or pathologic complete response, we conducted a retrospective study on 231 patients diagnosed with locally advanced rectal cancer who underwent neoadjuvant treatment. Results: Our results indicate that tumor characteristics remain the primary predictive factors for treatment response in rectal cancer patients. Specifically, we found that a complete pathologic response was more likely in patients with stage I/II disease compared to stage III/IV. However, we did not identify any statistically significant associations between radiotherapy characteristics (such as fractionation, treatment technique or total dose) and complete response rates. Conclusions: In conclusion, our study highlights the importance of tumor stage in predicting pathologic complete response following neoadjuvant chemoradiotherapy for rectal cancer patients. Other clinical and pathologic factors, such as tumor size, may also be important predictors of treatment response and should be explored in future studies.

RESUMO

BACKGROUND: Laparoscopy for benign ovarian pathology is the appropriate surgical approach and it has many well-known advantages. Minimal invasive gynecological surgery increases the quality of life of the patient. The learning process of laparoscopy is difficult and requires many interventions to acquire manual skills. The objectives of the study were to assess the learning process of laparoscopy for adnexal pathology surgery performed by beginner laparoscopists. MATERIALS AND METHODS: This study included three gynecological surgeons who were beginners in laparoscopy and who were named A, B, and C. We collected information about patients, diagnosis, surgical technique, and complications. RESULTS: We have analyzed the data from 159 patients. The most frequent primary diagnosis was functional ovarian cyst, and the laparoscopic cystectomy was performed in 49.1% of interventions. The need to convert a laparoscopy into laparotomy was necessary in 1.3% of patients. There were no cases of reintervention, blood transfusion, or ureteral lesions. The duration of the surgical intervention varied statistically significantly according to patient's BMI and to the surgeon. After 20 laparoscopic interventions, a significant improvement was found in the time needed to perform ovarian cystectomy (operators A and B) and salpingectomy (operator C). CONCLUSIONS: The process of learning laparoscopy is laborious and difficult. We found a significant decrease in operating time after a twenty laparoscopic interventions.

RESUMO

(1) Background: Cutaneous melanoma (CM) originates from melanocytes and causes 90% of skin cancer deaths; therefore, the comparison of different soluble and tissue markers could be valuable in the detection of melanoma progression and therapy monitoring. The present study is focused on the potential correlations between soluble S100B and MIA protein levels in different melanoma stages or with tissue expression of S100, gp100 (HMB45), and MelanA biomarkers. (2) Methods: Soluble S100B and MIA levels were evaluated by means of immunoassay methods in blood samples from 176 patients with CM, while tissue expressions of S100, MelanA, and gp100 (HMB45) were detected by means of immunohistochemistry in 76 melanomas. (3) Results: Soluble S100B correlated with MIA in stages III (r = 0.677, p < 0.001) and IV (r = 0.662, p < 0.001) but not in stages I and II; however, 22.22% and 31.98% of stage I and II patients, respectively, had high values for at least one of the two soluble markers. S100 tissue expression correlated with both MelanA (r = 0.610, p < 0.001) and HMB45 (r = 0.476, p < 0.01), while HMB45 and MelanA also significantly positively correlated (r = 0.623, p < 0.001). (4) Conclusions: Blood levels of S100B and MIA corroborated with melanoma tissue markers expression could help to improve the stratification process for patients with a high risk of tumor progression.

RESUMO

This case report delves into the intricacies of a challenging clinical scenario involving deep pelvic endometriosis, which manifested with renal complications. Endometriosis, a complex gynecological condition, is explored in this case, highlighting its multifaceted nature. The patient presented with a complex interplay of symptoms, including chronic pelvic pain, urinary tract issues, and severe deep adenomyosis. The diagnostic journey was protracted, emphasizing the need for early recognition and intervention in such cases. A thorough evaluation, including laparoscopic examination and histopathological analysis, revealed the extensive presence of endometriotic lesions in various pelvic and renal structures, ultimately leading to left hydronephrosis. The report underscores the significance of timely diagnosis and surgical intervention to prevent irreversible renal damage. This case provides valuable insights into the management of deep endometriosis with renal involvement and the importance of interdisciplinary collaboration. Understanding the complexities of this condition can aid in improving patient outcomes and enhancing the quality of care provided.

RESUMO

Radiotherapy (RT) plays a crucial role in all stages of lung cancer. Data on recent real-world RT patterns and main drivers of RT decisions in lung cancer in Romania is scarce; we aimed to address these knowledge gaps through this physician-led medical chart review in 16 RT centers across the country. Consecutive patients with lung cancer receiving RT as part of their disease management between May-October 2019 (pre-COVID-19 pandemic) were included. Descriptive statistics were generated for all variables. This cohort included 422 patients: median age 63 years, males 76%, stages I-II 6%, III 43%, IV 50%, mostly adeno- and squamous cell carcinoma (76%), ECOG 0-1 50% at the time of RT. Curative intent RT was used in 36% of cases, palliative RT in 64%. Delays were reported in 13% of patients, mostly due to machine breakdown (67%). Most acute reported RT toxicity was esophagitis (19%). Multiple disease-, patient-, physician- and context-related drivers counted in the decision-making process. This is the first detailed analysis of RT use in lung cancer in Romania. Palliative RT still dominates the landscape. Earlier diagnosis, coordinated multidisciplinary strategies, and the true impact of the multimodal treatments on survival are strongly needed to improve lung cancer outcomes.

RESUMO

BACKGROUND/AIM: Currently, the impact of diabetes mellitus (DM) on rectal cancer patients is complex and just partly elucidated. The purpose of this study was to investigate the impact of diabetes mellitus on rectal cancer patients focusing on tumor differentiation grade, neoadjuvant chemoradiotherapy (NACRT) response, disease-free (DFS) and overall (OS) survival. PATIENTS AND METHODS: Our study's population consisted of a group of 53 patients diagnosed with locally advanced rectal cancer, who underwent NACRT, followed by radical oncological surgery. This patient population was further divided into two groups according to diabetes presence. RESULTS: Downstaging rates, local control, DFS, and OS were lower in the DM subgroup compared to the non-DM locally advanced rectal cancer patients. CONCLUSION: The presence of DM at the time of diagnosis of locally advanced rectal cancer patients may be a negative predictive factor for response to neoadjuvant therapy, distant metastases, and local recurrences rates.

RESUMO

This review on recently published literature aims to summarize published data on pathologic complete response following neoadjuvant treatment in biopsy proven locally advanced rectal cancer patients. Published articles referring to pCR rectal cancer patients were identified using PubMed search. Eleven relevant articles were selected, based on tumor, treatment, and patient characteristics reporting. As a conclusion, rectal cancer patients with the highest chances of complete clinical or pathological response to neoadjuvant treatment are males, who are around 60 years, diagnosed with well or moderate differentiated locally advanced rectal cancer.

RESUMO

Adenocarcinoma and adenosquamous carcinoma (AS) are 2 rare histological types of cervix uteri cancer constituting almost 20% of all cervix cancers, leading to a lack in patient management guidelines. We report the case of a 32-year-old woman with an oligometastatic cervix AS for which a multimodal treatment approach was used. Despite the patient's bad prognosis, a complete response was achieved, which further resulted in excellent local control and prolonged survival. This case report serves the purpose of encouraging multidisciplinary team work and out-of-the-box thinking that should result in an individualized treatment for rare cancer subtypes.

RESUMO

Introduction: The current practice for patients with good response, important downstaging or complete remission after preoperative chemoradiation, is to perform surgery on the basis of initial pretherapeutical staging. In literature, varying approaches, like transanal endoscopic microsurgery and even "wait and see", are described for patients with good response after chemoradiation. However, considering the present level of available evidence, the wide-spread adoption of a "watch and wait" policy in those achieving a complete clinical remission cannot be justified. CASE REPORT: It is presented the case of a 63 years old patient, investigated and diagnosed with synchronous rectal cancer, inferior rectal cancer invading the perianal region and medium rectal cancer, located between 8 and 14 cm from the anal verge, pretheraputically staged cT4N2M0. The oncological board decides neoadjuvant radiochemotherapy. Restaging shows complete remission of inferior rectal tumor and ulcerative infiltrative remnant lesion in the medium rectum. The patient firmly declines colostomy, assuming recurrence risks. A TME low rectal resection with colorectal mechanical anastomosis is performed, postoperative evolution being favorable. Conclusions: Although, the radical surgery to be done would have been an abdomino-perineal resection, the patient's option to decline the colostomy imposed a radical intervention just for the proximal tumor. The inferior rectal tumor, with complete remission after neoadjuvant therapy was submitted to "wait and see" approach.
