Background. Nutrition and lifestyle elements can significantly support the therapeutic process in colorectal cancer (CRC) patients, which is the basis for tertiary prevention. The study aimed to assess the nutritional strategies and lifestyle of CRC patients and to determine differences in these behaviors depending on gender and age. Methods. The study group included 202 CRC patients. The research was carried out in two hospitals and using the snowball method. The research tool was an original questionnaire. Data were processed in statistical programs. p < 0.05 was considered statistically significant. Results. Patients reported many behavioral–nutritional side effects. Half of them did not use a therapeutic diet (n = 101; 50.0%). The majority of patients declared that they ate three meals a day (57.4%). Fruits and vegetables were mainly eaten raw (69.3%). Almost a quarter of patients were not physically active at all (22.3%). Men chose to fry meat significantly more often than women (27.7% vs. 19.3%) (p = 0.003). The elderly consumed fast food significantly less often than middle-aged (88.5% vs. 72.3%) (p = 0.03). Conclusions. Patients showed both pro- and anti-health activities. The findings revealed several noteworthy disparities in dietary habits and lifestyle choices based on gender and age, indicating that these factors can significantly influence the health management of CRC patients. The patients’ behaviors should be constantly monitored and intensified, especially through regular consultations and educational meetings with an oncology dietitian for nutritional tertiary prevention of chronic disease.

Background/Objectives: This nationwide population-based study investigated the overall survival (OS) of patients with metastatic pancreatic cancer (mPC) receiving first-line chemotherapy. Methods: Data from the National Health Insurance Service linked to the Korea Central Cancer Registry were used. Patients with mPC receiving first-line chemotherapy (2012–2019) were included and followed up until 2020. The gemcitabine plus nab-paclitaxel (GnP) and FOLFIRINOX groups were matched according to age, sex, and comorbidities. Results: In total, 8652 patients with mPC were treated with chemotherapy. GnP and FOLFIRINOX have been administered since 2016 and 2017, respectively. The median OS increased annually from 6 months in 2012–2013 to 10 months in 2018–2019. The median OSs in the GnP and FOLFIRINOX groups were significantly longer than those in patients receiving gemcitabine ± erlotinib. A total of 1134 patients from both the GnP and FOLFIRINOX groups were selected using propensity score matching. Before matching, the median OS was longer in the FOLFIRINOX group than in the GnP group (p = 0.0029). After matching, however, there was no significant difference in the median OS between the two groups (11 vs. 11 months, respectively, p = 0.2438). Conclusions: Patients with mPC receiving chemotherapy have shown improved OS since the introduction of GnP and FOLFIRINOX. After matching, OS did not differ between the GnP and FOLFIRINOX groups.

Background/Objectives: Stearoyl-coenzyme A desaturase 1 (SCD1) plays a crucial role in fatty acid metabolism. However, its roles in the feeding habit transformation of mandarin fish (Siniperca chuatsi) remain largely unknown. Methods: Juvenile mandarin fish (10.37 ± 0.54)g were trained to feed on an artificial diet and then divided into artificial diet feeders and nonfeeders according to their feed preference. Afterwards, the scd1 gene of mandarin fish (Sc-scd1) was identified and characterized, and its transcription difference was determined between S. chuatsi fed live artificial diets and those fed prey fish. Results: Our results show that Sc-scd1 coding sequence is 1002 bp long, encoding 333 amino acids. The assumed Sc-SCD1 protein lacks a signal peptide, and it contains 1 N-linked glycosylation site, 24 phosphorylation sites, 4 transmembrane structures, and 3 conserved histidine elements. We found that Sc-SCD1 exhibits a high similarity with its counterparts in other fish by multiple alignments and phylogenetic analysis. The expression level of Sc-scd1 was detected with different expression levels in all tested tissues between male and female individuals fed either live prey fish or artificial diets. Conclusions: In particular, the Sc-scd1 expression level was the highest in the liver of both male and female mandarin fish fed artificial diets, indicating that scd1 genes may be associated with feed adaption of mandarin fish. Taken together, our findings offer novel perspectives on the potential roles of scd1 in specific domestication, and they provide valuable genetic information on feeding habits for the domestication of mandarin fish.

Background: An antidiabetic medication regimen is crucial for maintaining glycemic control. Type 2 diabetes mellitus (T2DM) and cognitive dysfunction have a bidirectional relationship. This study aims to explore the impact that adjusting antidiabetic medication regimens has on medication adherence, glycemic control, and cognitive function in patients with T2DM and mild cognitive impairment (MCI). Methods: This is an observational cross-sectional analysis that includes 364 consecutive inpatients with T2DM. Clinical data were collected, medication adherence was assessed using the Medication Adherence Report Scale (MARS-5), and cognitive status was evaluated using the Chinese version of the Montreal Cognitive Assessment (MoCA) and Mini-mental State Examination (MMSE). These data were obtained both during hospitalization and at a three-month follow-up. Multivariable logistic regression analysis was applied to determine the association between changes in medication regimens and medication adherence, glycemic control, and cognitive function. Results: Baseline medication adherence was high across all three different cognitive status groups, with no significant difference in MARS-5 scores. At the 3-month follow-up, the group with a high adjustment ratio of antidiabetic medication regimens showed an increase in their hemoglobin A1c (HbA1c) level compared to the baseline, while the group with a low adjustment ratio showed a decrease in this level. In addition, the MoCA, MMSE, and MARS-5 scores of the high-adjustment group were significantly lower than those of the low-adjustment group. Conclusions: A high ratio of medication adjustment was significantly associated with worse medication adherence and glycemic control in T2DM patients with MCI. Patients with a low ratio of medication adjustment had good adherence and better glycemic control. Clinicians should take cognitive status into account when adjusting antidiabetic regimens for T2DM patients and may need to provide additional guidance to patients with cognitive impairment to improve adherence and glycemic outcomes.

Background/Objectives: The direct bridge to urgent heart transplant (HT) with venoarterial extracorporeal membrane oxygenation (VA-ECMO) support has been associated with high morbidity and mortality. The objective of this study is to analyze the morbidity and mortality of patients transplanted with VA-ECMO and compare the presumed differences between various eras over a 17-year timeline. Methods: This is a prospective, observational study on consecutive patients stabilized with VA-ECMO and transplanted with VA-ECMO from July 2007 to December 2023 at a reference center (98 patients). Objective variables were mortality and morbidity from renal failure, venous thromboembolic disease (VTD), primary graft dysfunction (PGD), the need for tracheostomy, severe myopathy, reoperation, post-transplant ECMO, vascular complications, and sepsis/infection. Results: The percentage of patients who reached transplantation without the need for mechanical ventilation has increased over the periods studied. No significant differences were found between the study periods in 30-day mortality (p = 0.822), hospital discharge (p = 0.972), one-year mortality (p = 0.706), or five-year mortality (p = 0.797). Survival rates in these periods were 84%, 75%, 64%, and 61%, respectively. Comorbidities were very frequent, with an average of 3.33 comorbidities per patient. The most frequent were vascular complications (58%), the need for post-transplant ECMO (57%), and myopathy (55%). The development of myopathy and the need for post-transplant ECMO were higher in recent periods (p = 0.004 and p = 0.0001, respectively). Conclusions: VA-ECMO support as a bridge to HT allows hospital discharge for 3 out of 4 transplanted patients. This survival rate has not changed over the years. The comorbidities associated with this device are frequent and significant. Full article

Background: Varicella infections follow a benign course in around 90% of cases, with more severe forms occurring in adults. To identify potential pockets of susceptibility and to improve targeted immunization strategies, this study aims to critically assess immunological status by evaluating varicella seroprevalence among adults (18–99 years) in the province of Florence (Italy), nearly a decade after Tuscany introduced the vaccination program. Methods: A convenience sample of 430 subjects aged 18 to 94 years (mean age 51.8 ± 18.8 years), stratified by age and sex (53.7% of subjects were female; N = 231), was collected between 2018 and 2019. Sero-analytical analyses were conducted utilizing EUROIMMUN Anti-VZV ELISA (IgG) kits. Results: Most of them were of Italian nationality (87.4%; N = 376). Among the 430 tested samples, 385 (89.5%) were positive and 39 (9.1%) were negative. The remaining six sera (1.4%), confirmed as equivocal, were excluded from further analysis. No significant differences were found based on sex (p-value = 0.706) or nationality (p-value = 0.112). The application of trend tests (Mantel–Haenszel; Kendall Tau-b) showed a significant trend (p < 0.024 and p < 0.032, respectively), with an increasing probability of finding a positive anti-varicella serological status passing from a lower age group (84.2%) to a higher one (93.0%). By considering the female population aged 18–49 years, the seroprevalence of anti-varicella antibodies was found to be 88.4%, with a susceptibility of 11.6%, highlighting the risk of acquiring infection during pregnancy. Conclusions: The introduction of varicella vaccination has had a significant impact on public health in Tuscany and in Italy more generally. However, further efforts should be made to reduce the number of individuals still susceptible in adulthood, with particular attention given to women of childbearing age and the promotion of vaccination through mass and social media and institutional websites.

Background: The outstanding capabilities of modern Positron Emission Tomography (PET) to highlight small tumor lesions and provide pathological function assessment are at peril from image quality degradation caused by respiratory and cardiac motion. However, the advent of the long axial field-of-view (LAFOV) scanners with increased sensitivity, alongside the precise time-of-flight (TOF) of modern PET systems, enables the acquisition of ultrafast time resolution images, which can be used for estimating and correcting the cyclic motion. Methods: 0.25 s so-called [¹⁸F]FDG PET histo image series were generated in the scope of for detecting respiratory and cardiac frequency estimates applicable for performing device-less data-driven gated image reconstructions. The frequencies of the cardiac and respiratory motion were estimated for 18 patients using Short Time Fourier Transform (STFT) with 20 s and 30 s window segments, respectively. Results: The Fourier analysis provided time points usable as input to the gated reconstruction based on eight equally spaced time gates. The cardiac investigations showed estimates in accordance with the measured pulse oximeter references (p = 0.97) and a mean absolute difference of 0.4 ± 0.3 beats per minute (bpm). The respiratory frequencies were within the expected range of 10–20 respirations per minute (rpm) in 16 out of 18 patients. Using this setup, the analysis of three patients with visible lung tumors showed an increase in tumor SUV_max and a decrease in tumor volume compared to the non-gated reconstructed image. Conclusions: The method can provide signals that were applicable for gated reconstruction of both cardiac and respiratory motion, providing a potential increased diagnostic accuracy. Full article

Background: Breast cancer (BC) comprises multiple subtypes with distinct molecular features, which differ in their interplay with host immunity, prognosis, and treatment. Non-invasive blood analyses can provide valuable insights into systemic immunity during cancer. The aim of this study was to analyze the expression of transcriptional isoforms in peripheral blood mononuclear cells (PBMCs) from BC patients and healthy women to identify potential BC immune biomarkers. Methods: RNA sequencing and isoform-level bioinformatics were performed on PBMCs from 12 triple-negative and 13 luminal A patients. Isoform expression validation by qRT-PCR and clinicopathological correlations were performed in a larger cohort (156 BC patients and 32 healthy women). Results: Transcriptional analyses showed a significant (p < 0.001) decrease in the ENST00000374459 RASGEF1A isoform in PBMCs of BC compared to healthy subjects, indicating disease-related expression changes. The decrease was associated with higher ctDNA and Ki-67 values. Conclusions: The levels of the RASGEF1A transcriptional isoform ENST00000374459 may have the potential to distinguish between BC and healthy subjects. The downregulation of ENST00000374459 in breast cancer is associated with higher proliferation and ctDNA shedding. Specialized bioinformatics analyses such as isoform analyses hold significant promise in the detection of biomarkers, since standard RNA sequencing analyses may overlook specific transcriptional changes that may be disease-associated and biologically important.

Background: Thyroid cancer is the most common endocrine carcinoma, accounting for 3.26% of all cancers. The most histologically, well-differentiated thyroid cancer is papillary thyroid carcinoma (PTC). Although PTC is regarded as an indolent tumor, a portion of the cancer cells metastasize to lymph nodes around the thyroid gland. Lymph node metastasis (LNM) is a critical risk factor for tumor recurrence in PTC, which strongly affects disease prognosis and the quality of life. Methods: This study aims to examine how differences in the level of the thyroid profile and other risk factors may influence LNM incidence in patients with PTC in Taiwan. We carried out a single-center retrospective study. These PTC patients were retrospectively reviewed by the Department of Endocrinology from 2016 to 2019. A total of 165 patients were included in our research. Results: The findings revealed a close relationship with the level of free thyroxine (FT4), the level of the thyroid-stimulating hormone (TSH), and lymph node metastases. The correlation in terms of FT4 (p = 0.005) and TSH (p = 0.417) with LNM was found as a result of the univariate regression analysis. In the multiple regression analysis, the findings revealed a close relationship between LNM, FT4 (p < 0.001), and TSH (p = 0.008). Conclusions: Although the predictability of the TSH should be examined further, the association between LNM and FT4 or TSH should not be ignored. The results could help guide decision-making and patient counseling, using the level of serum FT4 or the TSH as a possible predictive factor of the LNM in PTC. Full article

Background/Objectives: This study examined the differences in participant force production and pain between a squat maximal voluntary isometric contraction (IMVIC) performed with either a waist belt (WB) or full-body harness (FBH) on the Desmotec D.EVO isoinertial device (D.EVO). Agreement between FBH IMVIC and a traditional force plate squat MVIC (TMVIC) was also assessed. Methods: Twenty adults completed FBH, WB, and TMVIC assessments on two separate occasions. Two-way treatment x time ANOVAs were conducted to compare force outputs and pain between treatments (FBH vs. WB) across time. Test-retest reliability was assessed using intraclass correlation coefficients. Associations between outcomes were determined using Pearson’s r. Standard error of estimate, constant error, total error, and Bland-Altman plots were used to assess agreement between IMVIC and TMVIC. Results: FBH and WB IMVIC exhibited good to excellent reliability (ICC_2,1 = 0.889–0.994) and strong associations (r = 0.813 and 0.821, respectively) when compared to TMVIC. However, agreement between FBH and TMVIC was poor. No significant interaction or main effects were observed for pain. FBH maximum isometric force (MIF) was significantly higher than WB MIF. WB IMVIC was the only significant predictor of TMVIC (R² = 0.674). Conclusions: Our findings indicate that the D.EVO should not be utilized as a replacement for a traditional MVIC setup.

Background and Objectives: With increases in cancer incidence and the number of cancer survivors, the demand for cancer management is growing. However, studies on dental prosthetic treatment for patients with cancer are rare. We aim to investigate the dental prosthetic treatment in patients with cancer aged ≥65 years after expanded health insurance coverage. Materials and Methods: This retrospective study included patients who were treated with implants and removable dentures at Ulsan University Hospital in South Korea between June 2015 and June 2023. Data on age, sex, cancer location, comorbid systemic diseases, number of remaining teeth, dental prosthetic treatment history, type of dental prosthetic treatment, and insurance coverage status were extracted from patient medical records and panoramic radiographs. The influence of multiple variables on dental prosthetic treatment was analyzed using the Chi-square and Fisher’s exact tests. Results: The study included 61 patients with cancer (32 men, 29 women; average age: 70.9 years). Among them, 56 (91.8%) had insurance coverage benefits, and 34 (55.7%) received treatments such as implants, removable partial dentures, or complete dentures for the first time. Treatment types included 37 (60.7%) cases of implant prostheses and 24 (39.3%) conventional removable dentures. No statistical differences were observed in the type of dental prosthetic treatment according to sex, age, cancer location, number of systemic diseases, and dental prosthetic treatment history (p > 0.05). Patients with <10 remaining teeth received treatment with conventional removable dentures, which was statistically significant (p < 0.001). Conclusions: Of the 61 patients, 56 (91.8%) received insurance benefits, and 34 (55.7%) underwent dental prosthetic treatment for the first time. Within the limitations of this retrospective study, the expanded health insurance coverage alleviated the unmet demand for dental prosthetic treatment. As cancer prevalence continues to increase, expanding customized health insurance coverage is crucial to meet this demand. Full article

Background: With the advent of da Vinci SP, surgical methods using da Vinci SP are becoming popular in thyroid surgery. The authors previously reported on a new surgical method called the single-port robotic areolar (SPRA) approach, which evolved from the previous bilateral axillary breast approach (BABA). This paper reports a comparative analysis of SPRA and BABA over one year. Methods: The data on SPRA and BABA thyroid surgery performed at the authors’ hospital from December 2022 to December 2023 were analyzed. Results: 111 SPRA and 159 BABA surgeries were performed. SPRA was performed overwhelmingly on women (1 man vs. 110 women), and the body mass index (BMI) was lower in SPRA patients (23.63 ± 3.49 vs. 25.71 ± 4.39, p < 0.001). The proportion of total thyroidectomy was significantly higher in BABA patients, and a modified radical neck dissection (MRND) was only performed using the BABA method. The time for flap formation before robot docking was significantly shorter in SPRA patients (12.08 ± 3.99 vs. 18.34 ± 5.84 min, p < 0.001). Postoperative drain amount was also significantly lower in SPRA patients (53.87 ± 35.45 vs. 81.74 ± 30.26 mL, p < 0.001). Hospital stay after surgery was significantly shorter with SPRA (3.04 ± 0.48 vs. 3.36 ± 0.73 days, p < 0.001). Thyroglobulin levels after a total thyroidectomy (0.06 ± 0.13 vs. 0.45 ± 0.78, p = 0.002) and stimulated Tg level before the RAI (1.03 ± 0.74 vs. 5.01 ± 13.63, p = 0.046) were significantly lower in the SPRA group. No significant differences were observed between the two groups according to the postoperative complications, including vocal cord palsy and hypoparathyroidism. Conclusions: Based on the authors’ experience, SPRA is a less invasive robot thyroid surgery method than BABA. Full article

(1) Background: This study aimed to establish the effect of calcium lactate enamel pretreatment related to different fluoride types and concentrations on the enamel uptake of alkali-soluble fluorides. (2) Materials: In a blind and randomized in vitro study, a total of 60 teeth are used. The first 30 teeth were cut and randomly allocated into one of the following treatments: (A) calcium lactate pretreatment followed by three different fluoride solutions; (B) the “Fluoride only” group, with slabs treated with three different fluoride solutions; (C) the “Calcium only” group, with slabs treated with calcium lactate solution; (D) slabs treated with deionized water (negative control group). The next 30 teeth underwent all the above described group procedures but were treated with lower fluoride concentrations. Fluoride was extracted from enamel using 1 M KOH solution and analyzed using a fluoride ion-specific electrode. (3) Results: The findings revealed that slabs treated with NaF following calcium lactate pretreatment exhibited significantly greater enamel uptake of alkali-soluble fluoride compared to other substrates. This significant effect was not observed at lower fluoride concentrations. (4) Conclusion: The study demonstrates that pretreatment with calcium lactate followed by treatment with NaF at 226 ppm F significantly enhances the uptake of alkali-soluble fluoride in enamel compared to other fluoride types.

Remote-sensing technology has gradually become one of the most important ways to extract sea–land boundaries due to its large scale, high efficiency, and low cost. However, sea–land segmentation (SLS) is still a challenging problem because of data diversity and inconsistency, “different objects with the same spectrum” or “the same object with different spectra”, and noise and interference problems, etc. In this paper, a new sea–land segmentation method (PMFormer) for remote-sensing images is proposed. The contributions are mainly two points. First, based on Mask2Former architecture, we introduce the prompt mask by normalized difference water index (NDWI) of the target image and prompt encoder architecture. The prompt mask provides more reasonable constraints for attention so that the segmentation errors are alleviated in small region boundaries and small branches, which are caused by insufficiency of prior information by large data diversity or inconsistency. Second, for the large intra-class difference problem in the foreground–background segmentation in sea–land scenes, we use deep clustering to simplify the query vectors and make them more suitable for binary segmentation. Then, traditional NDWI and eight other deep-learning methods are thoroughly compared with the proposed PMFormer on three open sea–land datasets. The efficiency of the proposed method is confirmed, after the quantitative analysis, qualitative analysis, time consumption, error distribution, etc. are presented by detailed contrast experiments.

Background: Experimental models of neurocysticercosis (NCC) are helpful for an improved understanding of the pathophysiological mechanisms of human diseases and for testing novel therapeutic approaches. Controlling inflammation without reducing the effectiveness of anthelmintics is an important challenge in treating neurocysticercosis. This study investigates the effects of currently used drugs (Albendazole and Dexamethasone) in treating murine extraparenchymal NCC. Methods: Twenty-two rats were inoculated with Taenia crassiceps in the subarachnoid space. The animals underwent magnetic resonance imaging to ascertain the success of infection 3 months after inoculation. The infected animals were randomly assigned to one of the three groups (five rats each): control (no treatment), Albendazole (ABZ), or Albendazole + Dexamethasone (ABZ + DXM) for 14 days. The animals were subsequently euthanised for morphological assessment 2 weeks after the end of treatment. Results: Macroscopically integrated cysts were found in all animals. The ABZ + DXM animals demonstrated lower ventricular sizes, lymphocyte infiltration rates, and immunopositivity for IL-6, with statistical differences in lymphocytes within the arachnoid region. Conclusions: This experimental model, which has previously shown similarities to human infections, is also helpful in reproducing the morphological changes upon treatment with Albendazole and Dexamethasone.
