The Mediterranean diet, one of the healthiest known diets, is renowned for its cardioprotective effects. We investigated the possible roles of new molecules such as spexin (SPX) and pentraxin-3 (PTX-3) in the protective effect of hydroxytyrosol (HT), one of the primary main components of olive oil, in rats fed corn syrup. Methods: The animals were divided into four groups of n=6 rats each: Group I (Control), Group II (HT), Group III (Corn Syrup), and Group IV (Corn Syrup+HT). The rats were given 30% corn syrup with drinking water for 6 weeks. Liquid containing HT (4 ml/kg/day) was applied by oral gavage alone and together with corn syrup for 6 weeks. SPX and PTX-3 were examined histopathologically in the animals’ heart tissue after the rats were sacrificed, and histoscores were created for SPX and PTX-3 immunoreactivity. The data were analyzed using both one-way ANOVA and Tukey’s HSD test. Results: We detected a decrease in SPX (P<0.001) and an increase in PTX-3 (P=0.013) in the Corn Syrup group compared with the Control group. After HT treatment, an increase in SPX (P=0.025) and a decrease in PTX-3 (P<0.001) were detected. There were no differences between the HT and Control groups. Conclusion: The protective effects of HT against heart damage might be conferred via SPX and PTX-3. These molecules are considered to be important target molecules involved in the diagnosis and treatment of metabolic diseases.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135245833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is no specific treatment for sepsis or sepsis-induced lung injury. Antioxidant therapy has been one of the most prominent options for treatment, according to pathophysiological studies. The aim of this study was to investigate the effects of quercetin, a powerful antioxidant, on sepsis and sepsis-related lung injury. Methods: Thirty-two adult male Sprague Dawley rats were divided into five groups. The control group (CNRL) received 1.5 ml saline via the intragastric route. The quercetin group (QUER [n=5]) underwent no sepsis procedure and received 20 mg/kg quercetin via the intragastric route starting 15 days before the procedure. The sham group (SHAM [n=6]) underwent a surgical incision and received 1.5 ml intragastric olive oil (quercetin dissolves in oil). The sepsis group (SEPS [n=7]) underwent the sepsis procedure. The sepsis and quercetin group (SEPS+QUER [n=7]) underwent the sepsis procedure and received 20 mg/kg quercetin via the intragastric route for 15 days before the procedure. Cecal ligation and puncture methods were used to induce sepsis. While ALT, AST, LDH, GGT and CRP values were analyzed from rat blood, MDA and GSH levels were analyzed from lung tissue. Results: The results showed that quercetin reduced neutrophil infiltration (TLIS 3.5 [0.26] in the SEPS group vs TLIS 2.75 [0.29] in the SEPS+QUER group [P=0.01]), intra-alveolar macrophage count (SEPS vs SEPS+QUER [P=0.01]) and cell proliferation (SEPS vs SEPS+QUER [P=0.01]), and that it helped to preserve lung anatomy during sepsis. It was observed that MDA levels in the lung tissue decreased with the treatment of quercetin to septic rats (SEPS vs SEPS+QUER [P=0.046]). Conclusion: These findings suggest that quercetin may be a potential treatment option for sepsis. However, more studies are needed to determine whether quercetin is a viable option as a therapeutic strategy in patients.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135195342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment options range from minimally invasive methods to surgical interventions involving wide excision. This study evaluates the outcomes of Kite excision, which aims to preserve healthy tissues, in cases of complicated PS extending along the natal cleft line. Methods: This retrospective cohort study included cases of complicated PS extending along the intergluteal sulcus. Patients with minimally extended PS, sinus openings extending laterally, or patients in whom the defect area was closed using other methods (e.g., rotation flap or Limberg flap) were excluded. Patient data were obtained from medical records and the hospital information system: patient age, gender, body mass index (BMI), length of hospital stay, duration of drainage, follow-up period, presence of flap necrosis or flap edema, wound dehiscence, and presence of seroma, hematoma, or surgical-site infections. Results: A total of 41 patients were included in the study; five (12%) were female. Twenty-three patients (56%) had recurrent PS; 18 patients (44%) underwent surgery for the first time. The mean age of the cohort was 28.5 years (standard deviation: 5.1 years). The mean BMI of the group was 30.2 kg/m2 (standard deviation: 2.9 kg/m2), and the mean hospital stay was 1.3 days (standard deviation: 0.6 days). Wound dehiscence was observed in two patients (4.9%), and hematoma beneath the flap was observed in one patient (2.4%). Seroma was detected in one patient (2.4%). A surgical-site infection was identified in two patients (4.9%). The overall postoperative complication rate was 14.6%, and recurrence was observed in one patient (2.4%). Conclusion: Kite excision performed along the natal cleft line in cases of complicated PS is a safe, effective, and minimally invasive procedure that preserves healthy tissues. It is a recommended surgical treatment option in cases of complicated PS with vertical extension, and it will reduce the incidence of recurrence and increase patient comfort.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135579368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, studies of their etiology and treatment approaches are of particular importance. The aim of this study was to analyze the etiological, demographic, and seasonal characteristics of patients presenting to the Kastamonu Training and Research Hospital Ear, Nose, and Throat (ENT) clinic in Kastamonu, Turkey complaining of vertigo/dizziness. Methods: In this retrospective cohort study, the files of 1033 patients who presented at the clinic with a report of vertigo/dizziness between September 2020 and September 2021 were examined. The patients’ demographic characteristics, presentation dates, and diagnoses were recorded. Results: Six hundred and fifty-one patients (63%) were female, and the mean age of the patient cohort was 50.3 years (standard deviation: 16.0 years). Six hundred and twenty-seven patients (60.7%) were identified with chronic subjective dizziness, 302 (29.2%) were identified with benign paroxysmal positional vertigo, 18 (1.7%) were identified with vestibular migraine, 7 (0.7%) were identified with bilateral vestibulopathy, 41 (4.0%) were identified with unilateral vestibulopathy, 16 (1.5%) were identified with vestibular neuritis, 6 (0.6%) were identified with Meniere’s disease, 10 (1.0%) were identified with central vertigo/dizziness, 3 (0.3%) were identified with labyrinthitis and 3 (0.3%) were identified with another form of vertigo/dizziness. An increase in the number of cases was observed in the spring, and the number of patients presenting with vertigo/dizziness decreased thereafter and reached a minimum in the fall (P<0.001). Conclusion: The most common vestibular disorder was chronic subjective dizziness. Vestibular disorders are more common in women and in the spring season. Although ENT specialists generally focus on pathologies of the ear, vertigo/dizziness are symptoms that may involve several etiologies. Meticulous clinical examinations should be performed; the etiological cause and clinical diagnosis in these cases will dictate additional tests to be requested and therapeutic strategies. Due to the broad diagnostic spectrum of these cases, a multidisciplinary approach is also critical.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136059000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the World Health Organization, old age is divided into three stages: 65–74 years, 75–84 years, and 85 years and older. The lengthened human lifespan leads to a growth in the number of elderly patients in intensive care units, and the need to know the factors associated with prognosis in the three stages of old age. We aimed to define factors affecting mortality in these three stages of aging and the factors that can help predict prognoses. Methods: In this retrospective cohort, data of patients over the age of 65 who were admitted to the intensive care unit of Bolu Izzet Baysal State Hospital between January 2016 and December 2020 were recorded using the hospital's automation system. Demographic data, blood tests, diagnoses and inflammatory biomarkers, such as RDW, NLR, and CAR were recorded. The data were analyzed using SPSS, and P<0.05 was considered significant. Results: In this study, 46.2% of the 1566 patients died. The most common diagnosis for admission to the intensive care unit was sepsis, and the most common comorbidity was hypertension. While neurological impairment (P<0.001), malignancy (P=0.006), and cardiac disease (P=0.004) were associated with mortality in all three stages of old age, chronic obstructive pulmonary disease was associated with mortality in the 85 years and older age group (P=0.011) and diabetes in those aged 65–74 years and 75–84 years. The APACHE II score (P<0.001) and red cell distribution width (P<0.001) were highly effective in predicting prognoses in all three stages of old age.

Methods: Between March and June 2020, we retrospectively assessed 6966 patients who visited Kartal Dr. Lütfi Krdar City Hospital’s Infectious Diseases and Clinical Microbiology COVID-19 outpatient clinics; 137 patients with loss of taste and smell were included in the study. We enrolled 18-year-old patients who were admitted to the infection emergency outpatient clinics. Results: Out of the 6966 patients hospitalized with a pre-diagnosis of COVID-19 infection, 137 (0.19%) complained of poor taste and smell. Among these, 69 (50.4%) were female, and 68 (49.6%) were male. Of the 137 patients, 100 (73%) reported a loss of smell, while 94 (68.6%) reported a loss of taste.

In this study, the aim was to histopathologically investigate the increase in neurotoxicity in the central nervous system due to bupivacaine in experimental renal failure. Methods: In the study, a total of 28 male Wistar albino rats, aged 8-10 weeks, were evenly divided into four groups: Group C (control group) received intraperitoneal 1 mL/kg saline; Group G (glycerol group) received intramuscular 10 mL/kg glycerol, Group GB (glycerol+bupivacaine group) received intramuscular 10 mL/kg glycerol followed by intraperitoneal 4 mg/kg bupivacaine; and Group B (bupivacaine group) received intraperitoneal 4 mg/kg bupivacaine. All rats were sacrificed after the experimental period. Tissue samples were preserved and stained with hematoxylin-eosin for histopathological analyses. TRPM2 and Reelin levels in brain tissue were measured using immunohistochemical methods. Results: In the histopathological examination, Group G exhibited higher Reelin and TRPM2 levels compared to all other groups (P<0.001).

Methods: Patients undergoing appendectomy between March 2019 and March 2021 in the General Surgery Department of our hospital were included in the study. The period between March 2019 and March 2020 and the period between March 2020 and March 2021 were considered as the period before the pandemic and the pandemic period, respectively. Patients in the period before the pandemic were classified as Group A and the ones in the pandemic period as Group B. The patients were randomly selected from the computer system.

Current biomarkers that are used to estimate inflammation are normal in some patients despite having active disease. Recent studies have revealed that oxidative stress may have a role in AS and that there is a close relationship between oxidative stress and inflammation. Ischemia-modified albumin (IMA) is a promising new biomarker for oxidative stress. Thus, the aim of this study was to assess IMA levels and their relationship with disease activity and other inflammatory markers in patients with AS. Methods: This prospective case-control study included 48 patients with AS and 25 healthy controls (HCs). The measured serum levels of IMA, interleukin (IL)-17, and IL-23 were compared between patients with AS and the HC group. We also analyzed the correlation between IMA and disease activity, acute phase reactants, and HLA-B27 positivity. The Ankylosing Spondylitis Disease Activity Score with C-Reactive Protein (ASDAS-CRP) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were used to determine disease activity. Results: There was no difference in serum IMA levels between the AS and HC groups (25.08 [20.49-46.83] vs. 29.89 [29.89-42.0], P=0.146). Only IL-23 was significantly higher in patients with AS (10.81 [7.25-14.06] vs. 7.95 [6.85-10.46], P=0.039). Furthermore, there was no correlation between IMA and IL-23, IL-17, CRP, ESR, BASDAI, or ASDAS-CRP (r=-0.079, P=0.593; r=-0.043, P=0.771; r=-0.018, P=0.906; r=0.047, P=0.751; r=0.281, P=0.053; r=0.162, P=0.271). There was no significant difference between IMA, IL-17, and IL-23 levels in patients with low disease activity (BASDAI <4, ASDAS-CRP <2.1) and high disease activity (BASDAI ≥4, ASDAS-CRP ≥2.1) (BASDAI: P=0.146, P=0.303, P=0.071, and ASDAS-CRP: P=0.451, P=0.410, P=0.324, respectively). There was no difference in IMA levels between HLA-B27-positive patients and HLA-B27-negative patients (P=0.070). Conclusion: Although oxidative stress has been suggested to play a role in AS pathogenesis, we did not find an increase in serum levels of IMA, an oxidative stress biomarker, in patients with AS. Our results suggest that IMA may not be a reliable indicator of inflammation. Further research is needed to determine whether IMA may have a role as a biomarker in AS.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135107473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A patient's prognosis is determined by the degree of differentiation of these tumor types. The objective of the present investigation was to assess the efficacy of volumetric apparent diffusion coefficient (ADC) histogram analysis in assessing the degree of differentiation for these two tumor types. Methods: This retrospective cohort research evaluated 54 PPAC (45 well-differentiated and nine poorly differentiated) and 15 IPAC (11 well-differentiated and four poorly differentiated) patients. Magnetic resonance imaging (1.5 T MRI) scans were used to evaluate the results. The features of the histogram for the ADC values were computed and incorporated several statistical measures, such as the mean, minimum, median, maximum, and percentiles in addition to the skewness, kurtosis, and variance. Results: In both PPAC and IPAC patients, the ADC values exhibited lower values in the poorly differentiated group when compared with the well-differentiated group. However, the changes between groups did not reach statistical significance. Among IPAC patients, the well-differentiated group had a larger kurtosis (P=0.048). In IPAC patients, the calculated value for the area under the curve (AUC) of kurtosis was determined to be 0.818. When the threshold was set at 0.123, the specificity and sensitivity were observed to be 90% and 75%, respectively. Conclusion: Our research indicates that the kurtosis of ADC is an effective indicator to determine the level of IPAC differentiation. Analysis of the histogram at increased b values can provide valuable insights to help determine the degree of differentiation of IPAC using a noninvasive technique.","PeriodicalId":30878,"journal":{"name":"International Journal of Surgery and Medicine","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135014691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
