    Abstract Objective: Male erectile dysfunction is an important complication of rectal surgery. In this research, the effect of prostate dimensions on the development of postoperative erectile dysfunction in patients diagnosed with mid-rectum adenocarcinoma who underwent low anterior resection (LAR) is examined.
    Patients and methods: Thirty-one male patients diagnosed as mid-rectal adenocancer were included. The International Index of Erectile Function (IIEF) questionnaire was used to determine the patients' pre and postoperative erectile dysfunction levels, and the level of relationship between the change in these IIEF scores and prostate measurements determined by computed tomography were evaluated.
    Results: There were statistically significant differences between IIEF index score and anterior posterior (AP) and transverse (TR) measurements (p≤0.001; p≤0.001), but no statistically significant difference was found between craniocaudal (CC) measurement values (p=0.169).
    Conclusions: The risk of nerve injury will be higher in those with a small prostate transverse diameter. Intraoperative nerve monitoring should be recommended primarily in younger patient groups.

    Abstract The aim of this study was to evaluate the effect of the All-on-4 design and 4 alternative implant-supported fixed prosthesis designs on stress distribution in implants, peri-implant bone, and prosthetic framework in the edentulous mandible under different loading conditions using three-dimensional finite element analysis (3D-FEA).Five different experimental finite element models (Model A (unsplinted 6), Model B (splinted 6), Model C (All-on-4), Model D (axial; 2 anterior, 2 posterior), and Model E (4 interforaminal)) were created. Three different loading conditions were applied (canine loading, unilateral I-loading, and unilateral II-loading). The highest minimum (Pmin) and the maximum (Pmax) principal stress values were acquired for cortical and trabecular bones; the highest von Mises (mvM) stress values were obtained for implants and metal frameworks. Model B and Model D showed the most favorable stress distribution. The All-on-4 design (Model C) also showed acceptable stress values close to those of Model B and Model D in the cortical and trabecular bones. In accordance with the stress values in the bone structure, the lowest stress values were measured in the implants and Co-Cr framework in Model B and Model D. The highest stress values in all structures were measured for unilateral loading- II, while the lowest values were found for canine loading. It was concluded that Model B and Model D experimental models showed better biomechanical performance in all structures. Furthermore, the use of a splinted framework, avoiding cantilevers, results in lower stress transmission. On the other hand, canine loading and unilateral loading-I exhibited the best loading conditions.

    Abstract Many radiological techniques are used to locate the adenoma preoperatively in cases of primary hyperparathyroidism, but the location of many adenomas still cannot be detected. Since adenomas are hypervascular lesions, their temperature is high. Infrared thermal scanning can reveal local temperature differences in hypervascular lesions. The location of the adenoma could not be determined by preoperative radiological examinations in a 58-year-old male patient who was scheduled for surgery with the diagnosis of primary hyperparathyroidism. By infrared thermal scanning, a nearly 2°F higher temperature was measured in the inferior of the right thyroid lobe compared to the other perithyroidal regions. During the exploration, the adenoma was found at this point and removed. Infrared thermal scanning of the neck is promising as a new technique that can be used both preoperatively and intraoperatively to locate the adenoma in primary hyperparathyroidism cases.

    Abstract Purpose: The aim of this finite element analysis was to evaluate the stress distribution along a premolar's root dentin, its post, and post luting agent when materials with different elastic modulus are used to fabricate one-piece post-and-cores in 2 different design.
    Materials and methods: Two 3D virtual models (for cylindrical and conical post designs) of a mandibular premolar restored with one-piece post-and-core restorations were obtained by using a software. A total of eight post-and-core materials (polyether-ether-ketone (PEEK), polyether-ketone-ketone (PEKK), glass fiber-reinforced polyether-ether-ketone (GFR-PEEK), carbon fiber-reinforced polyether-ether-ketone (CFR-PEEK), gold-palladium alloy (Au-Pd), titanium (Ti), zirconia (Zi) and chromium-nickel (Cr-Ni)) were tested. Maxiumum principals stress (MPS) in the post, post luting agent, and root dentin were determined. A load of 150 N was applied to the buccal cusp in linguo-labial direction at an angle of 45° oblique to the longitudinal axis of the crown.
    Results: The highest MPS value in post structure was observed with Cr-Ni material for both post designs. Similarly, the highest MPS value in the post luting agent was observed for Cr-Ni, the material with the highest elastic modulus. However, in the root dentin, the highest value was observed in PEEK, the material with the lowest elastic modulus.
    Conclusion: Post material and design influenced the stress concentration in the post, post luting agent, and root dentin. The stress at root dentin was slightly higher for polymeric materials. Cylindrical post design revealed lower stresses than conical post design at root dentin for all post-and-core materials tested.

    Abstract Tools to measure layout people's knowledge about palliative care are very limited. This study aimed to examine the validity and reliability of the Palliative Care Knowledge Scale (PaCKS) in Turkish on layout people other than healthcare professionals. Perception of Health Scale (PHS) and European Health Literacy Survey (EHLS) scales were used to ensure concurrent validity of PaCKS. Cronbach's alpha value of the scale was found to be .846. In item analysis, item-total score correlations were found to be between .343 and .691. Intraclass correlation coefficient of PaCKS total score was found to be .862,

    Abstract In this study, datasheet provided temperature coefficients of commercially available photovoltaic modules were investigated by taking into account the actual performance parameters (output peak power, short-circuit current and open-circuit current) under different sky profiles (clear, partly cloudy and cloudy) at field by introducing a new validation procedure. This procedure is based on two cases. The first case covers irradiation and temperature whereas the second case covers only irradiation by neglecting the temperature coefficient parts in the actual performance parameters calculation. The actual performance parameters of mono crystalline silicon and cupper indium gallium selenide photovoltaic modules were measured under different sky profiles at field and calculated for considered cases. Measured and calculated results were compared by using the root mean square error and the relative mean error tools. It has been founded that temperature coefficients of commercially available photovoltaic modules could deviate from their datasheet provided values under cloudy sky profile at field. As a result of this, it has been concluded that users should take into account sky profiles at the site where photovoltaic modules are going to be deployed in order to calculate the actual performance parameters and the output energy accurately.

    Abstract Background: Iconographical Falls Efficacy Scale (Icon-FES) is the first visual scale for fear of falling. Unlike the others, Icon-FES, including 30 items offers a unique perspective to assess the fear of falling by providing more precise contexts.
    Objectives: The study aimed to introduce the 30-item Icon-FES, the first visual content fear of falling scale, into Turkish and to explore its psychometric properties.
    Methods: First, the Turkish language validity of Icon-FES was ensured by following the forward-backward translation protocol. A total of 150 older adults independent in their daily living activities were included in the study. Falls Efficacy Scale International (FES-I) and Activities Specific Balance and Confidence Scale (ABC), which are frequently preferred in the literature for the same purpose, were used to provide the criterion validity of the scale. The exploratory factor analysis method was utilised for the construct validity of the scale.
    Results: Factor analysis revealed a two-factor structure. 52.22% of the total variance was explained with single-factor analysis. In the criterion validity analysis, while there was a strong positive correlation between Icon-FES and FES-I (r = 0.910, p < 0.01), a strong negative correlation was found between Icon-FES and ABC (r = -0.887, p < 0.01). The Cronbach Alpha value for the internal consistency of the scale was calculated as 0.965. The intraclass correlation coefficient between two measurements performed one-week interval was found to be 0.985 (p < 0.001).
    Conclusion: The study showed that Icon-FES is a valid, reliable and rapid result assessment tool for community-dwelling older adults without cognitive dysfunction.

    Abstract Purpose: The number of lymph nodes is used to determine the prognosis in patients with gastric cancer undergoing D2 lymph node dissection. However, a group of extraperigastric lymph nodes, including lymph node 8a, are also considered to be effective in prognosis. In our clinical experience, in most patients during D2 lymph node dissection, the lymph nodes are removed en-bloc with the specimen and are not marked separately. The aim was to analyze the importance and prognostic impact of 8a lymph node metastasis in patients with gastric cancer.
    Methods: Patients who underwent gastrectomy and D2 lymph node dissection for gastric cancer between 2015 and 2022 were included in the study. Patients were divided into two groups based on metastasis to the 8a lymph node: metastatic and nonmetastatic. The effect of clinicopathologic features and the prevalence of lymph node metastasis on the prognosis of the two groups were analyzed.
    Results: The present study included 78 patients. The mean number of dissected lymph nodes was 27 (IQR, 15-62). There were 22 (28.2%) patients in the 8a lymph node metastatic group. Patients with 8a lymph node metastatic disease had shorter overall survival and shorter disease-free survival. Those with metastatic 8a lymph nodes among pathologic N2/3 patients had shorter overall and disease-free survival rates (p < 0.05).
    Conclusion: In conclusion, we believe that anterior common hepatic artery (8a) LN metastasis is a key factor that negatively affects both disease-free and overall survival in patients with locally advanced gastric cancer.

    Abstract The objective of this paper is to calculate the single diode model parameters (A, Rs, Rsh, IL, and I0) of photovoltaic modules in most straightforward way no using iterative techniques and an additional information of pre-measured/digitized current-voltage curves. For that purpose, a new method based on solely datasheet information is introduced. The novelty of this method is to use a dark saturation current as an initial parameter as calculating the single diode model parameters. The effectiveness of proposed was validated using current-voltage curves of five commercially available photovoltaic modules at standard test conditions. The current-voltage curves were simulated using the proposed method and compared with datasheet supplied current-voltage curves by means of a root means square error tool. It has been founded that the new method, which proposes a very simple calculation procedure to obtain the single diode model parameters, meets international standards as simulating current-voltage curves of photovoltaic modules.

    Abstract Objective: Surgical site infections (SSI) are incomparably troublesome and complicated, and some of them require an open abdomen (OA) procedure. While deciding the timing of abdominal closure, wound area calculation method and laboratory parameters can be used to guide the timing of abdominal closure after OA procedures.
    Patients and methods: The records of the patients who had undergone open abdomen during their treatment course and were followed up with vacuum-assisted closure (VAC) technique between December 2015 and December 2019 were retrospectively analyzed. The laboratory results before the first VAC application and the results after the VAC change were compared to determine a predictive parameter. The ImageJ program was used in five patients to compare the size of the wounds at the time of the decision to close them and before the first VAC application.
    Results: 102 patients were analyzed. The ratio of the last wound area to the wound area at the time of the first VAC application in five patients was 0.30, 0.41, 0.34, 0.27, 0.46 (mean: 0.36, standard deviation: 0.078) which were measured and calculated by ImageJ software.
    Conclusions: We think that the concept of wound reduction ratio, which was calculated by a computer program, can be used as a concrete equivalent of the wound closure eligibility criteria decided by clinical experience.
