Journal of Cardiovascular Imaging 2026;34(1):9-
Background:
Anthracycline-based chemotherapy is highly effective in breast cancer treatment but is limited by dose-dependent cardiotoxicity. Early identification of subclinical myocardial injury is crucial to prevent progression to irreversible dysfunction.
Objectives:
To evaluate whether a multimodal surveillance strategy integrating left ventricular global longitudinal strain (LVGLS), left atrial reservoir strain (LASr), and high-sensitivity troponin I (hs-TnI) can predict early anthracyclineinduced cardiotoxicity.
Methods:
This retrospective cohort study included 50 female breast cancer patients (mean age 49.3 ± 8.5 years) treated between January 2022 and December 2024. Echocardiography and biomarkers were assessed at baseline and 1 month after chemotherapy. Cardiotoxicity was defined as a > 10% reduction in LVEF to < 53%.
Results:
Cardiotoxicity occurred in 15 patients (30%). LVGLS, LASr, and hs-TnI significantly changed (all P < 0.001).Independent predictors were LVGLS (aOR 1.33), LASr (aOR 0.77), and hs-TnI (aOR 1.07). hs-TnI showed the highest discriminative ability (AUC 0.940).
Conclusions
LVGLS, LASr, and hs-TnI provide complementary information for early detection of cardiotoxicity.

Purpose:
Real-world evidence comparing surgical techniques for symptomatic hemorrhoidal disease (HD) remains limited, despite the availability of multiple approaches. This study aimed to evaluate short-term, interim outcomes from a prospective, nationwide cohort study that compared the effectiveness of different operative techniques based on patient-reported outcome measures (PROMs) in patients with symptomatic HD.
Methods:
A prospective, nationwide cohort study was conducted at 20 tertiary care centers across Turkiye between July 2022 and July 2024. Adult patients aged 18 years or older with symptomatic HD (grades I–IV) who underwent surgery during this period were included. The choice of procedure was determined by the operating surgeon, and patients were categorized into excisional, fixative, and ablative groups according to the surgical approach used. The primary outcomes were changes in the Hemorrhoidal Disease Symptom Score, Short Health ScaleHD, visual analog scale for pain, and patient satisfaction, assessed from the preoperative period to postoperative day 7 and postoperative week 6.
Results:
The study included a total of 315 patients after excluding those who did not fulfil the inclusion criteria. Among them, 239 (78.9%) were male, with a mean age of 43.7±11.7 years. The distribution of patients across surgical groups was 207 (65.7%) in the excisional group, 30 (9.5%) in the fixative group, and 78 (24.8%) in the ablative group. All groups demonstrated significant improvements in PROM scores from preoperative to postoperative assessments. However, no statistically significant differences were observed between groups at any time point for PROM scores or for changes in PROM scores across consecutive evaluations (P≥0.05 for all comparisons). Urinary retention occurred more frequently, and hospital stays were longer in the fixative group (P=0.006 and P<0.001, respectively). The excisional group had a greater need for narcotic use and longer duration of use (P=0.003 and P<0.001, respectively).
Conclusion
This real-world cohort study shows that all 3 surgical approaches are effective for HD, providing comparable short-term symptomatic relief and patient satisfaction. These techniques appear equally valid treatment options, and the choice of procedure may best be individualized based on patient-specific characteristics and surgeon preference.Trial registration: ClinicalTrials.gov identifier: NCT05429060

Objective:
This study aims to investigate the levels of nesfatin-1-hormone in patients with Antisocial Personality Disorder (ASPD) and their relationship with clinical variables.
Methods:
A total of 90 people (45 ASPD, 45 controls) were included in our study. Sociodemographic Data Form, Beck-Depression-Inventory (BDI), Beck-Anxiety-Inventory (BAI), Barratt Impulsivity Scale (BIS-11), Buss-Durkee-Hostility-Inventory (BDHI) were applied to all participants. Venous blood samples were taken from participants at the same time of the day when they were hungry.
Results:
It was found that the BDI and BAI scores of the ASPD were higher than those of the controls (p<0.001, for both scales). The scores in BIS-11; motor and nonplanning-impulsivity subscales were higher than those of the controls (p<0.001, 0.036, respectively). The scores obtained by the ASPD were higher in all subscales of BDHI (p<0.001). For the nesfatin-1-hormone, the values of the ASPD were lower than those of the controls (p=0.044). No relationship was found between the nesfatin-1-hormone and any other laboratory parameters and applied scales (p>0.05).
Conclusion
This is the first study to examine the nesfatin-1-hormone levels in patients with any personality disorder. Further studies with more participants are needed in different types of personality disorders to understand the relationship between personality disorder and nesfatin-1-hormone levels.

. The aim of the present study was to investigate the effects of surface treatments on the bond strengths between polymer-containing restorative materials and two dual-cure resin cements. MATERIALS AND METHODS.In the present study, rectangular samples prepared from Lava Ultimate (LU) and Vita Enamic (VE) blocks were used. The specimen surfaces were treated using CoJet sandblasting, 50 μm Al2O3 sandblasting, % 9 HF (hydrofluoric) acid, ER,Cr:YSGG laser treatment, and Z-Prime. Dual-cure resin cements (TheraCem and 3M RelyX U 200) were applied on each specimen’s treated surface. A micro-tensile device was used to evaluate shear bond strength. Statistical analysis was performed using the SAS 9.4v3. RESULTS. While the bond strengthusing TheraCem with LU or VE was not statistically significant (P=.164), the bond strength using U200 with VE was statistically significant (P=.006). In the TheraCem applied VE groups, Z-Prime and HF acid were statistically different from CoJet, Laser, and Sandblast groups. In comparison of TheraCem used LU group, there was a statistically significant difference between HF acid and other surface treatments. CONCLUSION. The bondingperformance between the restorative materials and cements were material type-dependent and surface treatment had a large effect on the bond strength. Within the limitations of the study, the use of both U200 and TheraCem may be suggested if Z-prime was applied to intaglio surfaces of VE. The cementation of LU using TheraCem is suitable after HF acid conditioning of the restoration surfaces.

OBJECTIVE: We aimed to assess the association between cord blood brain-derived neurotrophic factor (BDNF) concentration and maternal depression during pregnancy. METHODS: A total of 48 pregnant women, admitted for elective caesarean section to Department of Obstetrics and Gynecology, The Konya Research and Training Hospital and Konya Necmettin Erbakan University Meram Medical Faculty, were included in this study. The study group included 23 women diagnosed as having depression during pregnancy and the control group included 25 pregnant women who did not experience depression during pregnancy. RESULTS: The groups had similar sociodemographic characteristics. Cord blood BDNF concentration was significantly lower in babies born to mothers with major depression as compared with those in the control group. We didn't find any correlation between the umbilical cord blood BDNF levels and BDI scores. CONCLUSION: The results suggest that the existence of major depression in pregnant women may negatively affect fetal circulating BDNF levels.

PURPOSE: The aim of this study was to evaluate the correlations between measurements made using panoramic radiography and cone-beam computed tomography (CBCT) based on certain anatomical landmarks of the jaws, with the goal of preventing complications due to inaccurate measurements in the pre-surgical planning phase of dental implant placement. MATERIALS AND METHODS: A total of 56 individuals who underwent panoramic radiography and a CBCT evaluation before dental implant surgery were enrolled in the study. Measurements were performed to identify the shortest vertical distance between the alveolar crest and neighboring anatomical structures, including the maxillary sinus, nasal floor, mandibular canal, and foramen mentale. The differences between the measurements on panoramic radiography and CBCT images were statistically analyzed. RESULTS: Statistically significant differences were observed between the measurements on panoramic radiography and CBCT for all anatomical structures (P < .05). The correlation coefficients (r) between the paired samples obtained from panoramic radiography and CBCT were closely correlated (P < .05), with r values varying from 0.921 and 0.979 for different anatomical regions. CONCLUSION: The results of this study support the idea that panoramic radiography might provide sufficient information on bone height for preoperative implant planning in routine cases or when CBCT is unavailable. However, an additional CBCT evaluation might be helpful in cases where a safety margin cannot be respected due to insufficient bone height.

INTRODUCTIONRestless legs syndrome (RLS), also known as Willis-Ekbom disease, is characterised by abnormal sensations in the legs as well as dysaesthesia. Although the aetiology of RLS has not yet been determined, it may be associated with systemic inflammation. The neutrophil-to-lymphocyte ratio (NLR) is a new and simple marker indicating systemic inflammation. The present study aimed to investigate the relationship between systemic inflammation and RLS through the use of the NLR.
METHODSA total of 75 newly diagnosed patients with RLS and 56 healthy control subjects were included in the study. Baseline NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count. The NLRs of the two groups were compared.
RESULTSThere were no significant differences in gender and age between the two groups. The NLR was 1.96 ± 0.66 in the patient group and 1.67 ± 0.68 in the control group (p = 0.005). Receiver operating characteristic analysis was performed to determine the cut-off value of NLR to predict RLS. The NLR was predictive at 1.58 with a 64% sensitivity and 50% specificity (95% confidence interval 0.55-0.74, area under curve 0.648 ± 0.05). The NLR was found to be statistically higher in patients with RLS and may be used to predict RLS.
CONCLUSIONThe aetiology of RLS remains undetermined. The present study showed that systemic inflammation may play a role in RLS. However, RLS could also be associated with systemic inflammatory diseases. This relationship is supported by high NLR values, which are related to chronic systemic inflammation.

Hepaticojejunostomy is an important part of many surgical procedures including pancreaticoduodenectomy. Biliary leakage from hepaticojejunostomy may be associated with intraabdominal abscess formation, biliary peritonitis, and even mortality. A 72-year-old female patient was admitted to our hospital with obstructive jaundice. After initial evaluation, she was diagnosed with distal common bile duct obstruction without accurate diagnosis. Before planned pancreaticoduodenectomy, biliary drainage with a T-tube was performed due to the presence of cholangitis. After the first operation, pancreaticoduodenectomy was performed. Postinflammatory changes around the hilar region made the hepaticojejunostomy risky. A bilio-digestive anastomosis was performed using a new technique. A nasogastric tube was placed into the common bile duct proximal to the anastomosis. The postoperative course of the patient was uneventful. The use of a nasogastric tube as a stent in risky hepaticojejunostomies is a simple technique that can be beneficial.

OBJECTIVE: Many neurochemical systems have been implicated in the development of Posttraumatic Stress Disorder (PTSD). The prolidase enzyme is a cytosolic exopeptidase that detaches proline or hydroxyproline from the carboxyl terminal position of dipeptides. Prolidase has important biological effects, and to date, its role in the etiology of PTSD has not been studied. In the present study, we aimed to evaluate prolidase activity in patients with PTSD. METHODS: The study group consisted of patients who were diagnosed with PTSD after the earthquake that occurred in the province of Van in Turkey in 2011 (n=25); the first control group consisted of patients who experienced the earthquake but did not show PTSD symptoms (n=26) and the second control group consisted of patients who have never been exposed to a traumatic event (n=25). Prolidase activities in the patients and the control groups were determined by the ELISA method using commercial kits. RESULTS: Prolidase activity in the patient group was significantly lower when compared to the control groups. Prolidase activity was also significantly lower in the traumatized healthy subjects compared to the other healthy group (p<0.01). CONCLUSION: The findings of the present study suggest that the decrease in prolidase activity may have neuroprotective effects in patients with PTSD.

OBJECTIVE: Human serum paraoxonase (PON1) prevents lipids from peroxidation and functions as an antioxidant mechanism. Malonyldialdehyde (MDA) is the final product of lipid peroxidation and can be used as an indicator of oxidative stress. The aim of this study was to investigate PON1, MDA, and arylesterase (ARY) levels in schizophrenic patients who are taking typical, atypical, or combined (typical and atypical) antipsychotic drug treatment, with respect to those of healthy controls. METHODS: We evaluated 41 patients (11 taking typical antipsychotics, 19 taking atypical antipsychotics, 11 taking combined anti-psychotics) and 43 healthy controls. RESULTS: MDA levels were higher in schizophrenic patients taking typical antipsychotics compared with healthy controls (p=0.001). ARY levels were higher in patients taking atypical antipsychotics compared with healthy controls (p=0.005). PON1 activity was similar in all groups. CONCLUSION: Our results indicate that treatment with typical antipsychotic drugs could be related to increased MDA levels; and antipsychotic medication may increase PON1 levels in schizophrenic patients.
