RESUMEN

BACKGROUND: Tertiary hyperparathyroidism describes the autonomous and excessive secretion of parathyroid hormone (PTH) by the parathyroid glands after longstanding secondary hyperparathyroidism in chronic kidney disease. Brown tumors are a sign of uncontrolled hyperparathyroidism. In this case, we have reported a refractory and destructive hyperparathyroidism storm. Also, it presented with atypical onset and unexpected adenoma location. CASE PRESENTATION: A 37-year-old man was diagnosed with end-stage kidney disease 22 years ago. He has been undergoing dialysis treatment since that time. Recently, he was admitted to the ophthalmology department due to the unilateral anterior bulging of the right eye and drooping of the eyelid. Magnetic resonance imaging exhibited an extraconal mass lesion located in the right orbital posterior superolateral position. Computerized tomography scans considered expansile bone lesion with peripheral calcification and originating from the sphenoid wing. The bone mass lesion was resected via craniotomy due to the compressive effect. The pathological findings were consistent with brown tumors. Plasma intact PTH level was 4557 pg/mL. The patient informed that he underwent parathyroidectomy and two leg fractures operation in a medical query. Parathyroid scintigraphy determined three distinct foci consistent with adenomas and one of them was in mediastenum. Second parathyroidectomy was recommended to the patient but the patient refused surgery. Despite his medication and dialysis regimen being revised, PTH levels were maintained at higher levels in follow-up. CONCLUSIONS: We presented a hyperparathyroidism case that was resistant to all treatments and exhibited all the severe complications in a long-term dialysis patient. Furthermore, this case has revealed the importance and difficulty of secondary hyperparathyroidism management.

RESUMEN

STUDY OBJECTIVE: Various retropubic and midurethral sling techniques have shown high cure rates in the treatment of stress urinary incontinence (SUI). This study aimed to compare single-incision midurethral sling (SIMS) and laparoscopic Burch colposuspension (LBC) procedures in patients with SUI in terms of the effectiveness, patient satisfaction, surgical complications and results. DESIGN: This is a prospective randomized study. SETTING: A university tertiary hospital. PATIENTS: Forty patients with clinically and/or urodynamically proven SUI who agreed to surgical treatment were randomized to the SIMS and LBC groups and included in the study. INTERVENTIONS: Patients were treated with SIMS and LBC operations. MEASUREMENTS AND MAIN RESULTS: Demographic characteristics of patients, physical and pelvic examination, preoperative and postoperative clinical findings, Kings Health Questionnaire form, Female Sexual Function Index and Prolapse Quality of Life Questionnaire form, postoperative day 1 visual analog scale score, and postoperative complications were recorded. Objective and subjective success rates were recorded by re-evaluating the patients in the first and sixth months of the operation. Objective success was defined as having a negative stress test and subjective success was defined as the absence of stress-induced urine leakage after surgery in a validated questionnaire. The primary result of our study was considered to be objective success, whereas the secondary result was subjective success and life quality tests. Twenty patients each in the SIMS group and the LBC group were included in the study. No significant difference was found in objective success (90% vs 85%, p = .633) or subjective success (85% vs 75%, p = .695) between the 2 groups at 6-month follow-up. A significant improvement in life quality was observed in the postoperative period for both groups; however, the difference between the groups was not significant. There was an improvement in sexual function in both groups. Nonetheless, although this improvement was significant in the SIMS group, it was not significant in the LBC group. In addition, surgery time, catheterization time, and hospitalization time were shorter in the SIMS group than in the LBC group. The visual analog scale score on postoperative day 1 was lower in the SIMS group. Groups were not different in terms of preoperative and postoperative complications. CONCLUSION: This preliminary study is the first randomized study that compares the LBC and SIMS procedures in the literature. It shows that SIMS and LBC procedures have not different objective and subjective success rates in the short term. It was also observed that they increase both sexual and life quality results in a positive and similar way.

RESUMEN

BACKGROUND: Microscopic polyangiitis (MPA), a kind of antineutrophil cytoplasmic autoantibody associated vasculitis (AAV), predominantly affects small-sized vessels. MPA is a significant cause of the pulmonary-renal syndrome. Pauci-immune necrotizing and crescentic glomerulonephritis is the typical renal histological feature of AAV. Tubulointerstitial lesions may occur and mostly form with inflammatory cell infiltration in the interstitium. However, a few cases reported only tubulointerstitial involvement without glomerular lesions in patients with MPA. CASE PRESENTATION: We present an MPA case, a 70-year-old male patient diagnosed with acute kidney injury accompanying the dialysis requirement. Only acute tubulointerstitial nephritis was revealed in kidney biopsy without evidence of glomerular injury. Also, interstitial pulmonary fibrosis was determined on computerized tomography, and myeloperoxidase antineutrophil cytoplasmic autoantibody was positive. Consequently, we have considered the main diagnosis as MPA. We did not prefer a standard tubulointerstitial nephritis treatment regimen due to the presence of life-threatening systemic vasculitis. Treatment was established like crescentic glomerulonephritis. Induction therapy consisted of pulse steroid, cyclophosphamide, and plasmapheresis. Unfortunately, severe SARS-CoV-2 infection caused death during induction therapy in this case. CONCLUSIONS: The lack of glomerular injury and solely interstitial inflammation is atypical regarding AAV involvement in the kidney. This diversity might be initially considered as only a simple histological elaboration. However, it is a significant entity for guiding the treatment of AAV.

RESUMEN

Thin endometrium, defined as an endometrial thickness of less than 7 mm during the late follicular phase, is a common cause of frequent cancelation of embryo transfers or recurrent implantation failure during assisted reproductive treatment. Small proteoglycans regulate intracellular signaling cascades by bridging other matrix molecules and tissue elements, affecting cell proliferation, adhesion, migration, and cytokine concentration. The aim of the study is to investigate the role of small leucine-rich proteoglycans in the pathogenesis of thin and thick human endometrium and their differences from normal endometrium in terms of fine structure properties. Normal, thin, and thick endometrial samples were collected, and small leucine-rich proteoglycans (SLRPs), decorin, lumican, biglycan, and fibromodulin immunoreactivities were comparatively analyzed immunohistochemically. The data were compared statistically. Moreover, ultrastructural differences among the groups were evaluated by transmission electron microscopy. The immunoreactivities of decorin, lumican, and biglycan were higher in the thin endometrial glandular epithelium and stroma compared to the normal and thick endometrium (p < .001). Fibromodulin immunoreactivity was also higher in the thin endometrial glandular epithelium than in the normal and thick endometrium (p < .001). However, there was no statistical difference in the stroma among the groups. Ultrastructural features were not profoundly different among cases. Telocytes, however, were not seen in the thin endometrium in contrast to normal and thin endometrial tissues. These findings suggest a possible role of changes in proteoglycan levels in the pathogenesis of thin endometrium.

RESUMEN

Glioblastoma (GBM) is the most common type of primary brain tumors in adults, characterized by its ability to proliferate rapidly and its tendency to aggressively and strongly invaded the surrounding brain tissue. The standard treatment approach of GBM is surgical resection followed by simultaneous chemotherapy and radiation. However, a significant number of GBM cases develop resistance to currently used chemotherapeutic drugs. Therefore, there is a need for the development of new chemotherapeutic agents. Trifoliumpratense L. is an endemic plant containing various isoflavones such as biochanin A, genistein, daidzein, and formononetin in high concentrations, and it has been shown in various studies that these molecules can function as anticancer agents. The present study was designed to determine the effect of the possible anticarcinogenic effects of the Trifolium pratense L. which grown in our country and to obtain new treatment approaches alternative to the classical treatment protocols applied in the treatment of GBM. C6 glioblastoma cells were cultured with Trifolium pratense L. Cell proliferation, apoptotic cell morphology, and cell structure were evaluated with CCK8, Annexin V, cytochrome c, CD117, and Betatubulin labeling, respectively. And also, investigated effects of this Turkish tetraploid on GBM by TEM. Decreased cell proliferation and increased number of apoptotic cells were observed depending on the increasing doses of Trifolium pratense L. In addition, intense morphological changes were detected depending on increasing doses. In this context, we believe that the plant Trifolium pratense L., may be a new alternative and adjuvant agent for the treatment of GBM.

RESUMEN

Nomophobia has been studied extensively due to its negative effects on human health and psychology. In terms of clinical psychology, nomophobia has been linked consistently to depression and anxiety. Studies also investigated whether it is a dependency, an impulse control problem, an obsession or a phobia; however, no clear clinical representation was confirmed. Although it was proposed to be added as an official diagnosis to DSM-5, these attempts were inconclusive. In this study, nomophobia was examined clinically by SCL-90 factors. A hierarchical regression analysis was performed by controlling anxiety, depression, phobia and obsessions by putting them in the first step. At the next step, paranoid ideation was entered while interpersonal sensitivity was introduced at the last step. The variables were assigned according to the steps according to their connections confirmed by the literature, the correlation coefficients and ß weights obtained in the current study. The hierarchical regression analysis confirmed that after controlling anxiety, depression, phobia and obsessions, nomophobia is explained by interpersonal sensitivity. Paranoid ideation is also an important variable in step 2, but it lost its significance in the last step. Nevertheless, it was thought that what makes people sensitive to interpersonal issues is a kind of fear of missing out others' experiences (FoMO) which is related to nomophobia. This fear of missing out might prepare people to constantly check on mobile phones thinking paranoid about what they might have been missing or deprived of. Clinical implications and limitations were discussed.

RESUMEN

RESEARCH QUESTION: Endoplasmic reticulum stress (ERS) is caused by the accumulation of the misfolded or unfolded proteins in the endoplasmic reticulum and induces the unfolded protein response (UPR). Peritoneal fluid is important in the pathogenesis of endometriosis. In this study, the role of UPR associated with ERS in endometriosis, and peritoneal fluid, were investigated. DESIGN: Normal, eutopic and ectopic endometrium tissues were divided into menstrual cycle phases, and endometrial stromal cells (ESC) were treated with 10-20% concentration of control peritoneal fluid and peritoneal fluid obtained from women with endometriosis for 10, 30 and 60 min, and 24 and 48 h. The UPR signalling proteins were analysed immunohistochemically and immunocytochemically. Data were compared statistically. RESULTS: p-IRE1 was increased in ectopic glandular and stromal cells in the early proliferative phase compared with normal and eutopic endometrium. p-PERK increased in ectopic glandular and stromal cells in the late proliferative phase compared with normal endometrium. ATF6 was increased in ectopic glandular epithelium compared with normal endometrium in the proliferative phases, versus eutopic endometrium in the late secretory phase. p-IRE1 and p-PERK were increased in high concentrations of ESC treated with peritoneal fluid obtained from women with endometriosis for 10, 30 and 60 min compared with controls. In ESC treated with peritoneal fluid from women with endometriosis, p-IRE1 decreased at 24-48 h compared with 30 min. CONCLUSIONS: In endometriosis, UPR pathways are activated as highly dependent on cell type and phase. Also, p-PERK and p-IRE1 increased because of exposure to high-dose peritoneal fluid from women with endometriosis in stromal cells. Our findings provide a basis for further studies searching for a potential biomarker for the diagnosis of endometriosis.

RESUMEN

AIM: This study aimed to determine the approaches of family physicians in Turkey towards the fasting of diabetic patients and whether they used international treatment guidelines when making recommendations. In addition, this study also aimed to increase the awareness of family physicians about this issue before Ramadan, which is a month of fasting. MATERIAL AND METHOD: The study herein comprised cross-sectional, observational research. Before Ramadan 2018, a structured questionnaire form, which was unique to this study, was prepared based on the guidelines of the International Diabetes Federation (IDF) and the American Diabetes Association (ADA), through platforms where family physicians gather via social media and mail groups, and sent to family physicians in Turkey via a link using an electronic questionnaire preparation and application programme. Moreover, the total knowledge level, attitude, and approach scores were calculated from the questions prepared from the relevant guidelines. RESULTS: Participating in the survey were 262 family physicians. Only 22% of the family physicians stated that they were aware of the international guidelines for Ramadan and diabetes management, and only 10% said that they had read them. The mean knowledge level, attitude, and approach scores were determined to be lower than expected, and a significant difference was found between the scores and academic titles. CONCLUSION: The lack of international guidelines on the subject, and of knowledge and experience about Diabetes Mellitus (DM) patient management during the month of fasting, stood out as the biggest problems. This study revealed that the awareness and competence of family physicians in disease management should be increased, in addition to that of fasting before, during, and after Ramadan in patients with DM, which has increasing prevalence in Turkey.

RESUMEN

The purpose of this study was to investigate the opinions of health professionals (HPs) who provide family planning counselling (FPC) within the scope of primary health care services since they are perceived as role models by the society. The number of HPs providing family planning counselling in primary health services in Turkey was 43,000 and 40,000 of these individuals were invited to participate in this observational, cross-sectional study via e-mail and social media. There were 740 responders and all were included in the study. Physicians providing FPC within the scope of primary health care services consisted of 45.1% of the responders and the remaining were nurses. Among all HPs, 59.7% had insufficient awareness regarding Turkey's population growth. Most of the HPs (52.4%) believed that the ideal number of children was 2 or less. The abortion rate was 9.1% in all pregnancies of HPs. The rate of caesarean section was 56% in all live births. According to responses, 75.6% of all pregnancies experienced by HPs were planned. According to 42.1% of the HPs, abortion must be performed if there is a life-threatening situation for the mother or if the fetus has some abnormalities. The most common method of birth control used by married HPs between the ages of 18 and 49 was male condoms (39.9%), while the pull-out method ranked first in the general population (25.5%). It was found that HPs, who had different opinions and practices about family planning than the general population, had insufficient awareness regarding population growth. Increased awareness of demography and FPC among HPs will likely contribute to the quality of service and the general wellbeing of the population.

RESUMEN

Victimology concerns victims of various traumas from accidents, disasters, assaults to wars. Survivors of trauma are also an area in clinical psychology since it is interested in the assessment and diagnosis of psychopathology and psychotherapy. Stress and mental health are intertwined; increased stress results in difficulties in feeling, thinking and behaving. The stress symptoms are an intrusion, avoidance, negative cognitions and mood, and arousal and reactivity. A trauma survivor might develop post-traumatic stress disorder. Healing trauma is so comprehensive that many professionals work from different aspects. From attorneys to mental health workers, many professionals deal with the aftereffects of trauma. Engaging with details of the trauma endangers not only the victims but also the professionals working with the victims. These professionals end up having psychological effects such as secondary trauma, vicarious trauma, compassion fatigue, countertransference and occupational burnout. Trauma has serious effects on its victims but not all effects are negative and paralyzing. Trauma victims might change their priorities in a way that they report more personal control over their life. This phenomenon is called posttraumatic growth. The paper aims to collaborate victimology with clinical psychology by highlighting psychopathology and psychological assessment.

RESUMEN

BACKGROUND: Cognitive impairment is common among hemodialysis (HD) patients and is associated with poor treatment compliance and mortality. The aim of this study is to evaluate relatively young HD patients with less comorbidities using the Montreal Cognitive Assessment (MoCA) and identify clues for earlier detection of cognitive impairment with the help of cognitive subscale scores. MATERIALS AND METHODS: A total of 103 chronic HD patients (mean age 48.3 years) and 37 stage-3 to 5 chronic kidney disease (CKD) patients with similar demographics were included. Patients with cerebrovascular disease, dementia, depression, malignancy, and infections were excluded. All participants were tested with MoCA. Patients with an MoCA global score < 24/30 were considered cognitively impaired. Groups were compared for MoCA subscales and clinical features. RESULTS: 75 patients (72.8%) in the HD group and 19 in the CKD group (51.3%) had impaired cognition. The number of patients with cognitive impairment was significantly higher in the HD group compared with the CKD group (p = 0.024). The mean total MoCA score was lower in the HD group (p = 0.043). MoCA subscale analysis revealed that the mean score for visuospatial/executive domain was significantly lower in the HD group (p = 0.001). CONCLUSION: In this study, we showed that cognitive impairment was more common in HD patients compared with predialytic CKD patients. This difference was predominantly related to the difference in executive scores. We may think that young HD patients with less comorbidities are also at risk for cognitive impairment. Noticing progressive declines in MoCA cognitive domains, before the development of global cognitive impairment, could be beneficial for HD patients.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the effect of mineralized plasmatic matrix (MPM), comprising a combination of synthetic graft and platelet concentrates, on bone regeneration. METHODS: Critical size defects of 6-mm diameter were created on the tibias of 6 male sheep, with the animals subsequently assigned into 2 groups. Of the 5 bone defects generated per animal, 4 were randomly filled with MPM, beta-tricalcium phosphate graft (ß-TCP), platelet-rich fibrin (PRF) + ß-TCP, and autogenous graft. One defect was left empty as a control group. Animals were killed at 3 weeks (early healing group) and 6 weeks (late healing group). The specimens underwent histologic and histomorphometric analysis to evaluate new bone formation. RESULTS: In both healing periods, new bone formation from autogenous bone was observed significantly more often than from biomaterials or the empty defect. The degree of new bone formation for MPM was significantly higher than that of the control group at all healing periods. In addition, it was significantly higher in both healing periods than that of ß-TCP albeit only in the late healing period than that of the PRF + ß-TCP combination. In all biomaterial groups, residual graft ratios decreased from early to late healing periods. CONCLUSION: The results indicated that MPM, representing growth factors in a fibrin network, increases new bone formation in surgically created defects in sheep tibia as confirmed by histologic assessment.

RESUMEN

OBJECTIVES: Type 2 diabetes (T2DM) is one of the most serious challenges of the 21th century with life-threatening complications and excessive health care costs. In diabetic patients, the main goal in T2DM treatment is the regulation of both blood glucose and lipid levels. For that, Gliclazide (GLZ), an oral antidiabetic, and Atorvastatin (ATV), a lipid lowering agent, are widely used drugs as combination. Diabetes has been reported severe impacts on male reproductive system; however, data obtained about ATV and GLZ treatment alone or in combination are conflicted or insufficient. Herein the effects of ATV and GLZ on male reproductive system in type 2 diabetic male rats have been investigated in the present study. METHODS: T2DM was induced by high-fat diet and single injection of streptozotocin (STZ) (35 mg/kg) in young adult male Sprague-Dawley rats. The diabetic rats were given ATV (10 mg/kg), GLZ (10 mg/kg) and ATV/GLZ (1:1, 10 mg/kg) combination by oral gavage for 28 days. The hormone levels were determined in the cardiac blood samples; and the histopathological and ultrastructural analyses were conducted in the testicular tissues and epididymal sperms. RESULTS: It was observed that diabetes had severe effects on testicular tissue and spermatogenesis. ATV treatment did not affect sperm count and testes structure (p > 0.05), however ameliorated sperm morphology (p < 0.05). GLZ treatment increased sperm count, and improved sperm morphology, testes structure and spermatogenesis (p < 0.05). ATV/GLZ combination treatment enhanced sperm morphology and improved testicular structure (p < 0.05) while did not affect sperm count (p > 0.05). CONCLUSION: GLZ treatment regenerated testicular damage and sperm parameters whether alone or in combination with ATV in diabetic rats without affecting hypothalamic-pituitary-gonadal axis.

RESUMEN

OBJECTIVE: Parathyroid hormone (PTH) enhances bone healing. Strontium ranelate (SR) is an antiresorptive agent that increases bone formation. Reports about combined effects of PTH and SR on local bone regeneration in osteoporotic subjects are limited. We aimed at investigating the efficacy of PTH and SR for promoting new bone formation in critical-sized defects of ovariectomized rats. MATERIALS AND METHODS: Parathyroid hormone- and/or SR-containing poloxamer implant tablets with/without chitosan microparticles were delivered locally to calvarial defects of 90 Wistar rats. Biopsies were analyzed histologically and histomorphometrically at 4 and 8 weeks of healing. RESULTS: Histomorphometry revealed that PTH alone promoted new bone formation at 4 weeks but the efficiency declined in 8 weeks. There was no positive effect of SR alone on bone formation at 4 or 8 weeks. Calvarial defects treated with PTH+SR combinations showed statistically significant greater new bone formation than either treatment alone at both time intervals. Tissue responses were modest and supported the good biocompatibility of the biomaterials used. CONCLUSION: Parathyroid hormone and SR combinations can be effective for calvarial bone regeneration of ovariectomized rats. PTH plus SR may have potential use as bone graft material in orthopedic and dental surgery to enhance bone healing and osseointegration.

RESUMEN

BACKGROUND: This study investigated the effect of laparoscopic sleeve gastrectomy (LSG) performed for morbid obesity on serum lipid levels of dyslipidemic and normolipidemic patients. METHODS: 141 patients who underwent LSG between September 2014 and January 2016 were included in the study. RESULTS: The patients' mean body mass index was 46.27 ± 6.79 kg/m2 preoperatively, 31.60 ± 5.37 kg/m2 in the 6th month postoperatively and 27.80 ± 4.25 kg/m2 in the 12th month (p < .001). Preoperatively and 12 months after the operation, mean total cholesterol (TC) levels and mean LDL cholesterol, mean HDL cholesterol, and mean triglyceride (TG) levels were statistically significantly decreased (p < .01). Comparing TC levels in the 12th month with preoperative levels, dyslipidemic patients showed a statistically more significant decrease than normolipidemic patients. LDL cholesterol levels were significantly decreased in both the groups. HDL cholesterol levels increased significantly in both groups while mean TG levels decreased significantly in patients with high preoperative TG levels, but not in patients with normal preoperative TG levels. CONCLUSIONS: Although this technique exerts its effect primarily by reducing gastric volume, besides its metabolic and hormonal effects, it also improves serum lipid levels (decreasing TC, LDL cholesterol and TG levels, and increasing HDL cholesterol levels). It therefore contributes to decreasing cardiovascular diseases.

RESUMEN

BACKGROUND: The effects of the menstrual cycle in women with and without primary dysmenorrhea on phase-related postural sensory organization are controversial. RESEARCH QUESTION: This study was carried out to examine postural sensory organization in three phases of the menstrual cycle in women with and without primary dysmenorrhea and to evaluate whether there is a difference between women with/without primary dysmenorrhea in this regard. METHODS: Women aged 18-30 years were divided into two groups as primary dysmenorrhea group (PDG, n = 14) and control group (CG, n = 15). Computerized dynamic posturography were applied to the participants on the follicular, ovulation, and luteal phases of the menstrual cycle. Outcome measures were antero-posterior and medio-lateral Sensory Organization Test (SOT-somatosensory, vestibular and visual scores) and Limits of Stability test (LoS). The findings obtained were analyzed with the two-factor ANOVA, paired samples t test, and independent samples t test. RESULTS: In the PDG, follicular phase antero-posterior somatosensory scores were lower compared to luteal phase (p = 0.002). Follicular phase antero-posterior and medio-lateral vestibular scores were lower than ovulation (p = 0.003, p = 0.004, respectively) and luteal (p = 0.005, p = 0.001, respectively) phases. Follicular phase LoS scores were lower than ovulation (p = 0.001) and luteal (p = 0.002) phases. In the CG, ovulation phase antero-posterior somatosensory scores were lower than follicular phase (p = 0.003). Follicular phase LoS scores were lower than ovulation phase (p = 0.002). The PDG had lower follicular phase antero-posterior somatosensory (p = 0.019), vestibular (p = 0.031), and medio-lateral somatosensory (p = 0.019) scores than those of the CG. The PDG had lower luteal phase antero-posterior somatosensory scores than those of the CG (p = 0.029). The PDG showed lower follicular phase LoS scores than those of the CG (p = 0.009). SIGNIFICANCE: This study revealed that primary dysmenorrhea impairs postural sensory organization. Decreased sensory organization may predispose women to injury. The risk of injury should be investigated and necessary precautions should be taken.

RESUMEN

Periodical health examination is one of the important factors influencing a healthy lifestyle. Patients undergoing routine physical examination in primary care are included in the scope of preventive medical services, which is the most basic principle of primary care. Identifying the risk factors enables individuals to adopt healthier lifestyle practices. In our study, we examined the correlation between patients undergoing coronary angiography for suspected coronary stenosis and the extent of primary care services they had received in their medical history, along with the severity of stenosis observed during the angiography. Patients were interviewed using a pre-structured questionnaire to gather information about their past utilization of primary healthcare services related to coronary matters and their cardiovascular (CV) risk profile as documented in their medical history. The necessary standard tests for angiography procedures were retrieved from patient records. The SYNTAX score, a tool that aids in the objective assessment of the severity of coronary artery disease (CAD), was computed and documented. This score was then compared with the history of primary care utilization. The patients' utilization of services from the Primary Healthcare Center (PHC) was evaluated using a scoring system, with an average score of 29.27 ±â€…11.27 out of 100 points (minimum: 20; maximum: 60). The average SCORE Türkiye indicating the 10-year risk of CV events for all patients was calculated as 14.31% ±â€…8.65% (high-very high risk), while the average SYNTAX score was 15.20 ±â€…9.97. There was a positive and significant correlation found between fasting blood glucose and creatinine values with both SYNTAX score and SCORE Türkiye (respectively; R = 0.238, P = .013; R = 0.289, P = .002). Factors such as smoking and metabolic syndrome were associated with CAD severity. It important to highlight that individual recommended for angiography had a notably lower utilization of healthcare services from the PHC based on their medical histories. This circumstance has resulted in individuals who do not undergo CV event screenings at PHCs having higher SYNTAX scores, indicating more severe CAD that necessitates angiography. Conducting regular periodical health examinations at PHCs can help mitigate these statistics.

RESUMEN

OBJECTIVE: The aim of the present study was to investigate the effects of the February 6, 2023, earthquakes in Turkey and recurrent aftershocks on balance and post-traumatic stress in surviving victims. METHODS: Our study included 1004 participants aged 18-65 years who were exposed to the February 6 earthquakes and aftershocks in Turkey. After obtaining online consent from all participants, the Vertigo Symptom Scale (VSS), the Dizziness Handicap Index (DHI), and the Posttraumatic Post-Traumatic Disorder Checklist Scale (PCL-5) were administered online, and the interactions between the variable sets were examined using a correlational screening model. RESULTS: As a result of the structural equation model established with the observed variables, it was found that VSS total scores had a statistically significant positive effect on PCL-5 (ß1 = 0.56; p = 0.001 < 0.05). In addition, statistically significant positive high-level correlations were found between VSS and DHI (covVSS-DHI = 0.71), and a positive low level correlation with the number of days with dizziness (covVSS-number of days with dizziness = 0.34), and a positive low level correlation with frequency of days with dizziness (covVSS-frequency of days with dizziness = 0.37). A statistically significant positive low-level relationship was found between DHI and the number of days with dizziness (covDHI-number of days with dizziness = 0.34) and a positive low-level correlation between DHI and the frequency of days with dizziness (covDHI-frequency of days with dizziness = 0.29). CONCLUSION: The structural equation modeling analysis showed that post-traumatic stress disorder had a significant effect on balance and dizziness.

RESUMEN

Purpose: Brain metastases are common among adult patients with solid malignancies and are increasingly being treated with stereotactic radiosurgery (SRS). As more patients with brain metastases are becoming eligible for SRS, there is a need for practical review of patient selection and treatment considerations. Methods and Materials: Two patient cases were identified to use as the foundation for a discussion of a wide and representative range of management principles: (A) SRS alone for 5 to 15 lesions and (B) a large single metastasis to be treated with pre- or postoperative SRS. Patient selection, fractionation, prescription dose, treatment technique, and dose constraints are discussed. Literature relevant to these cases is summarized to provide a framework for treatment of similar patients. Results: Treatment of brain metastases with SRS requires many considerations including optimal patient selection, fractionation selection, and plan optimization. Conclusions: Case-based practice guidelines developed by the Radiosurgery Society provide a practical guide to the common scenarios noted above affecting patients with metastatic brain tumors.
