Abstract	Background: The groin flap is axial pedicled and versatile. Until now, this flap has been used with many modifications for the reconstruction of forearm and hand defects. However, this flap has not been used in forearm, hand, and thumb reconstruction as a pedicled sensate osteocutaneous flap. In this study, a pedicled sensate osteocutaneous groin flap was used for the reconstruction of composite tissue defects on the forearm, hand, and thumb. Patients and methods: A pedicled sensate osteocutaneous groin flap was used to reconstruction composite tissue defects on the forearm, hand, and thumb in 7 patients. The mean age of the patients was 42 years. The defects were located on the dorsal surface of the forearm and hand in 2 patients, the dorsal surface of the hand and finger in 2 patients, and the thumb in 3 patients. The dimensions of the flap skin paddle ranged from 7 × 11 cm to 8 × 23 cm, and the dimensions of the bone component ranged from 1 × 1.5 × 3.5 cm to 1 × 1.5 × 5 cm. The mean follow-up duration was 26 months. Results: All the flaps survived. Flap debulking was performed using 3 flaps. Sensory recovery in the flaps was completed approximately 18 months after the first operation. When the results of static 2-point discrimination test and Semmes-Weinstein monofilament test were evaluated at 18 months postoperatively, it showed that protective sensation was obtained. Except for 1 patient, motion restriction did not develop in the wrist, elbow, or shoulder joints. An acceptable aesthetic result, minimal donor site deformity, and protective sensation were obtained in all patients. Conclusions: The pedicled sensate osteocutaneous groin flap can be safely used in the reconstruction of forearm and hand composite tissue defects that do not have available vascular structures for free flaps in the recipient area and in thumb reconstruction where toe transfer and pollicization cannot be performed.

Abstract	Background: The lower-extremity fillet flap is a suitable option for the repair of complex (multiple or complicated with osteomyelitis) stage IV pressure sores. If prepared from a nonfunctional extremity, it can close complex wounds and avoid the unnecessary burden of a nonfunctional organ that restricts patient movement, thereby improving quality of life. Methods: We used a lower extremity fillet flap for reconstruction in 5 patients with complex stage IV pressure sores. The flaps were prepared from the nonfunctional lower extremity with multiple lesions by using iliofemoral disarticulation. The mean age of the patients was 60 years old, and the mean follow-up period was 18 months. A plantar flap was used in 1 patient for prophylactic padding of the lumbosacral region. In another patient, the plantar flap was used as a sensate flap. Results: No major complications, such as total or partial flap loss, occurred in these patients. In 1 patient, a hematoma developed under the flap that led to dehiscence; however, it healed uneventfully without flap loss. Patients developed minimal pelvic stability and balance loss because of iliofemoral disarticulation, but it did not affect their sitting ability and mobility. After the operation, all patients became increasingly active and mobile because of the absence of excess weight on their nonfunctional legs, allowing them to easily perform daily activities such as turning in bed, using a wheelchair, eating, and dressing. Pressure sores did not develop in any of the patients during the postoperative follow-up period. The patient who underwent lumbosacral padding with a sensate plantar flap began to perceive touch over the flap in the fifth postoperative month. Conclusions: These results suggest that a lower-extremity fillet flap can be a good repair option in complex stage IV pressure sores because it prevents recurrence and enables patients to perform daily activities more easily. Furthermore, plantar flaps can provide prophylactic padding in the lumbosacral region.

Abstract	Background: The reverse superior labial artery flap was introduced in 2015 as a reconstructive option for medial cheek defects. Notably, this flap can be redesigned as a more effective repair tool for large facial defect reconstruction. In this study, we redesigned the reverse superior labial artery flap to include the vascular territories of the infraorbital and transverse facial arteries in larger sizes for the repair of large facial defects. Methods: A reverse superior labial artery flap was used to repair large facial defects in 17 patients with a mean age of 74 years. The defects were located in the orbital region and entirely nasal sidewall in patient two, buccal region in patient three, and in lower lip and malar areas in patient five. The flap sizes ranged from 3.5 × 10 to 7 × 15 cm. A sensory examination was performed on the flaps at 6 and 12 months postoperatively. The mean follow-up period was 12 months. Results: All flaps survived without partial or total loss. In a small number of flaps minor complications such as venous congestion, epidermolysis, and dehiscence were seen. No functional disability was observed in the lower eyelid or lower lip, and the esthetic appearance was evaluated as satisfactory by the patients. In all the flaps, the protective sensation was recovered in the postoperative 12th month. Conclusions: The reverse superior labial artery flap has an extensive arc of rotation, a reliable vascular pedicle, and a large cutaneous paddle. Therefore, this flap may be a versatile surgical repair tool for large cheek defects.

Abstract	Objective: This study examines the relationships between HIV stigma dimensions, self-related mechanisms, and depressive symptoms among persons living with HIV. Background: HIV stigma hinders the well-being of individuals living with HIV, which is linked to depressive symptoms and increased risk of poor clinical outcomes. However, the mechanisms underlying stigma's impact on depression are poorly understood. Psychosocial theories propose that experiencing HIV stigma leads to internalized stigma, impacting self-concept and mental health. Method: Using Bayesian network analysis, we explored associations among HIV stigma processes (experienced, anticipated, internalized, perceived community stigma, and HIV status disclosure) and self-related mechanisms (self-esteem, fear of negative evaluation [FNE], self-blame coping, and social exclusion), and depressive symptoms. Results: Our diverse sample of 204 individuals, primarily men, gay/bisexual, Black, and lower-middle SES, who experienced stigma showed increased anticipated, internalized, and perceived community stigma, FNE, and depressive symptoms. Internalized stigma contributed to self-blame coping and higher depressive symptoms. Anticipated and perceived community stigma and FNE correlated with increased social exclusion. Discussion: This study investigates potential mechanisms through which HIV stigma may impact depression. Identifying these mechanisms establishes a foundation for future research to inform targeted interventions, enhancing mental health and HIV outcomes among individuals living with HIV, especially from minority backgrounds. Insights gained guide evidence-based interventions to mitigate HIV stigma's detrimental effects, ultimately improving overall well-being and health-related outcomes for people with HIV.

Abstract	An increasing body of evidence suggests that a postoperative rise in cardiac troponin, even in the absence of other diagnostic criteria for myocardial infarction, is still associated with a range of postoperative complications including myocardial death and all-cause mortality. Myocardial injury after non-cardiac surgery is the term used to describe these cases. The true incidence of myocardial injury after non-cardiac surgery is unknown and likely underestimated. The strength of correlation with postoperative complications is also uncertain as are likely risk factors - though these are likely similar to those for infarction given the similar pathological mechanism. This review article seeks to summarise the literature which has been published over the preceding decades addressing these questions.

Abstract	Developing numerical methods to solve polydispersed flows using a Population Balance Equation (PBE) is an active research topic with wide engineering applications. The Extended Quadrature Method of Moments (EQMOM) approximates the number density as a positive mixture of Kernel Density Functions (KDFs) that allows physical source terms in the PBEs to compute continuous or point-wise form according to the moments. The moment-inversion procedure used in EQMOM has limitations such as the inability to calculate certain roots even if it is defined, absence of consistent result when multiple roots exist or when the roots are nearly equal. To address these limitations, the study proposes a modification of the moment-inversion procedure to solve the PBE based on the proposed Halley-Ridder (H-R) method. Although there is no significant improvement in the extent of variability relative to the mean of the tested shape parameter

Abstract	Background: Workplace-based assessment methods are essential in the assessment and evaluation of competency-based cardiology residency training. This study aims to determine the assessment and evaluation methods used in cardiology residency training in Türkiye and to reach the opinions of the institutions on the applicability of the workplace-based assessments. Methods: In this descriptive study, a Google Survey was sent to the heads/trainers of residency educational centers and their opinions about the currently used assessment and evaluation methods, applicability of cardiology competency exams, and the workplace-based assessments were asked. Results: Responses were received from 65 (76.5%) of 85 training centers. Of the centers, 89.2% reported using resident report cards, 78.5% case-based discussion, 78.5% direct observation of procedural skills, 69.2% multiple-choice questions, 60% traditional oral exams, and less commonly other exam types. About 74% of responders gave a positive opinion on the requirement of being successful in the Turkish Cardiology Competency knowledge exam before specialty. Case-based discussion was the most common work-place-based assessments that the centers think could be applied as suggested by the current literature. A common idea was the adaptation of workplace-based assessments based on international standards and our national norms. The trainers supported a nationwide examination for all training centers to ensure standardization. Conclusion: In Türkiye, it was promising to see that the trainers are positive about the applicability of workplace-based assessments, but they commonly thought that the proposed workplace-based assessments should be adapted before nationwide applicability. Medical educators and field experts need to work together on this issue.

Abstract	Objective: This study aimed to determine whether maternal cortisol levels affect fetal heart rate patterns in primiparous pregnant women in the third trimester. Methods: This cross-sectional descriptive study included 400 primiparous pregnant women with uncomplicated pregnancies between November and December 2022. The study included primiparous pregnant women over 18 years old in the third trimester who had not exercised for at least 2 h before the fetal heart rate monitoring and had a healthy pregnancy without consuming any food or drink. Fetuses with decelerating heartbeats and pregnant women who showed uterine contraction and cervical dilation during the fetal heart rate monitoring were excluded from the study. Research data were collected with the data collection form. The fetal heart rate data were collected using a cardiotocograph. At least two accelerations during the 20-min nonstress test period were the basis for diagnosing a reactive nonstress test. About 5 mL of maternal saliva for cortisol measurements was collected before fetal heart rate monitoring. Research data were analyzed with IBM SPSS Statistics for Macintosh, Version 28.0. A p-value of <0.05 was considered significant. Results: There were no significant differences in the comparison of the groups in terms of education and income status, family type, fetal gender, pregnancy planning status, BMI and age averages, or gestational week averages (p>0.05). The number of at least two accelerations required for the diagnosis of reactive NST was also higher in Group 1 (maternal salivary cortisol level ≤24.20). A moderately positive relationship between fetal heart rate and maternal salivary cortisol was observed (r=0.448, p=0.000). In total, 11.9% of the total change in fetal heart rate level is explained by maternal cortisol (R2=0.119). Maternal cortisol increases fetal heart rate level (ß=0.349). Conclusion: These findings suggest that stress in primiparous pregnant women with high cortisol levels may influence fetal heart rate patterns. It was revealed that the increase in cortisol level, considered a stress hormone, may be a harbinger of fetal tachycardia.

Title translation	Predicción de la proporción de aspartato aminotransferasa a alanina aminotransferasa (De Ritis) para detectar necrosis intestinal en pacientes con hernia inguinal incarcerada.
Abstract	Purpose: Early diagnosis of necrotic bowel segment resulting from incarcerated inguinal hernia (IIH) is crucial for reducing morbidity and mortality. The aim of this study was to investigate the efficacy of the De Ritis ratio (DRR), also known as the ratio of aspartate aminotransferase to alanine aminotransferase, as a biomarker for intestinal necrosis. Methods: This retrospective study included 132 patients who underwent emergency surgery for IIH. Patients were divided into two groups: those who underwent bowel resection for necrosis (Group 1) and those who did not (Group 2). Patients' demographic and clinical data were recorded. Using laboratory test results, DRR, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and lymphocyte-to-CRP ratio (LCR) were calculated. Results: The morbidity and mortality rates and the length of stay for Group 1 were statistically significantly different (p < 0.0001). The DRR, NLR, PLR, LMR, and LCR values of the same group were also significantly different (p < 0.05). Conclusion: DRR can be used as a biomarker for early diagnosis of bowel necrosis in patients with IIH.
