RESUMO

BACKGROUND: In 2022, the International Classification of Diseases (ICD-11) and an update of the Diagnostic Statistical Manual of Mental Disorders (DSM 5 TR) were released for implementation worldwide and now include the new Prolonged Grief Disorder (PGD). The newest definition of PGD is based on robust clinical research from the Global North yet until now has not been tested for global applicability. METHODS: The current study assesses the new PGD ICD-11 criteria in a large international sample of 1393 bereaved adults. The majority of the sample was included from the USΑ. Additionally, we conduct a sub-sample analysis to evaluate the psychometric properties, probable caseness of PGD, and differences in network structure across three regions of residency (USA, Greece-Cyprus, Turkey-Iran). RESULTS: The psychometric validity and reliability of the 33-item International Prolonged Grief Disorder Scale (IPGDS) were confirmed across the whole sample and for each regional group. Using the strict diagnostic algorithm, the probable caseness for PGD for the whole sample was 3.6 %. Probable caseness was highest for the Greece-Cyprus group (6.9 %) followed by Turkey-Iran (3.2 %) and the USA (2.8 %). Finally, the network structure of the IPGDS standard items and cultural supplement items (total of 33 items) confirmed the strong connection between central items of PGD, and revealed unique network connections within the regional groups. LIMITATIONS: Future research is encouraged to include larger sample sizes and a more systematic assessment of culture. CONCLUSION: Overall, our findings confirm the global applicability of the new ICD-11 PGD disorder definition as evaluated through the newly developed IPGDS. This scale includes culturally sensitive grief symptoms that may improve clinical precision and decision-making.

RESUMO

AIM: In order to determine the possible effects of diabetes, we aimed to investigate the expression of extracellular matrix proteins in the theca and granulosa layers in different follicular stages. METHODS: Thirty-two adult Wistar albino male rats were divided into 4 groups as control and sampled groups. Four, eight and twelve weeks after inducing diabetes with an intraperitoneal injection of streptozotocin (40 mg/kg), the expressions of laminin, type IV collagen and α3ß1 integrin in ovarian tissues were evaluated by immunohistochemical method. RESULTS: In our study, in the first month of diabetes, a significant increase was observed in laminin, type IV collagen and α3ß1 integrin expressions in all follicle types compared to the control group in both the theca and granulosa layers. Laminin and type IV collagen immunoreactivity tended to increase in D2 and D3 groups also. Integrin expression did not change in the newly formed follicles in the D2 and D3 groups, however, it tended to change and increase in the developing follicles. CONCLUSIONS: The changes in the expression of laminin, type IV collagen and α3ß1 integrin, which are the extracellular matrix proteins in the follicle, along with diabetes, show that diabetes plays a role in the regulation of follicular development (Tab. 4, Fig. 36, Ref. 29).

RESUMO

AIM: Cornus mas L is commonly used due to its anti-inflammatory, anti-carcinogenic and anti-oxidant properties. In the study, the effects of C. mas L extract on a solid tumor were examined in the Ehrlich solid tumor model developed in Balb/C type mice. METHODS: Ehrlich acid tumor (EAT) cells (1x106 EAT cell) from the stock animal were injected subcutaneously (s.c.) through the nape of the mice. Treatment groups of solid tumor-induced animals received 100 mg/kg and 200 mg/kg of C. mas L extract intraperitoneally (i.p.) for 14 days. RESULTS: Tumor volumes and animal weights were found to be statistically significant compared to the control group (p < 0.05). AgNOR staining was performed in tumor tissues. Statistically significant differences were observed between the groups in terms of TAA/NA ratio (p < 0.05). Immunohistochemical and biochemical parameters were also evaluated. An estimation of tumor proliferation of the lung, liver, brain, kidney, testis and tumor antioxidant parameters viz. lipid peroxidation, reduced glutathione (GSH), glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) was made. CONCLUSIONS: Our study showed that the anti-tumor effect of C. mas L in assisted tumor development with EAT cells, was mediated by the enhancement of oxidative stress with multiple mechanisms (Tab. 6, Fig. 12, Ref. 38).

RESUMO

INTRODUCTION: To evaluate skeletal and nasal volume changes before and after surgery in surgically assisted rapid palatal expansion (SARPE) without pterygomaxillary separation and compare the dental changes by digital model analysis and radiographic analysis. SETTING AND SAMPLE: Population A total of 18 patients (10 females and 8 males) aged 15-33 years and with completed skeletal development, who were referred to Oral and Maxillofacial Surgery Department, Dentistry Faculty, Istanbul University and who had SARPE indication were included in the study. MATERIALS AND METHODS: Skeletal changes, lower nasal volume, transverse diameters of bony nasolacrimal duct and dental changes have been evaluated by using Cone beam computed tomography (CBCT) before and 6 months after the surgery. CBCT data was determined by Mimics v.18.01. Dental changes have been also evaluated by digital model analysis program 'Shape Orthoanalyzer' and the data are compared with those obtained using CBCT. RESULTS: The results obtained from dental measurements made using CBCT and those obtained using scanning three-dimensional (3D) models were consistent with each other. CBCT demonstrated that lower anterior nasal volume and transverse diameters of bony nasolacrimal duct showed statistically significant increase before and after the surgery. CONCLUSIONS: According to the study findings, SARPE without pterygomaxillary separation was noted to be an effective procedure. Lower nasal volumes were increased and the maxilla expanded in the transverse direction in all patients. Dental evaluations that were performed in this digital model analysis also supported our findings in CBCT. Transverse diameters of the bony nasolacrimal duct were shortened at all patients.

RESUMO

INTRODUCTION: The purpose of this retrospective clinical study was to evaluate the indications for and the utility of reconstruction plates in the management of benign mandibular pathological lesions. The complications associated with plate use were also assessed. PATIENTS AND METHODS: The clinical and radiological data of 23 patients (16 males, 7 females) with large, benign mandibular pathologies were evaluated. During operations, reconstruction plates were used to prevent mandibular fracture or to allow for bone reconstruction after segmental or disarticulation resection. The mean follow-up time was 11.2months. RESULTS: Condylar sag was observed in one patient who had undergone disarticulation resection. A reconstruction plate was removed from one patient because of pain. A plate became exposed in one patient who had undergone a disarticulation resection. Two patients reported slight paraesthesia. Screw-loosening was observed in one patient who had received a non-locking plate. CONCLUSION: Reconstruction plates can be safely used to manage benign mandibular lesions. Preoperative bending of the plates on individualised models is useful for reducing the time required for plate adaptation during operation. Locking reconstruction plates are preferable for preventing screw-loosening. All complications can be managed with careful follow up.

RESUMO

ANK3 encodes AnkyrinG (AnkG), a member of the Ankyrin family that is expressed in several different isoforms in many tissues. A unique serine-rich domain and tail domain in the two largest isoforms of AnkG (270 and 480kDa), restrict AnkG to the axon initial segment and nodes of Ranvier of myelinated neurons. At these sites, AnkG is a master regulator, coordinating the strict clustering of components necessary for proper action potential initiation and propagation along the axon. These components include voltage-gated sodium channels, potassium channels and members of the L1 cell adhesion molecule family. Genetic variation in the ANK3 gene has been linked to a range of neuropsychiatric and neurodevelopmental disorders in human, including schizophrenia, bipolar disorder, intellectual disability and autism spectrum disorders. Here, we study the effect of reduced expression of the large isoforms of Ank3 on cognition and behaviour using a heterozygous knockout mouse model. In three independent behavioural tests, being the open field test, elevated plus maze and social interaction test, we found evidence for increased anxiety in our Ank3 mouse model. Besides, we observed specific neuroanatomical defects in heterozygous knockout mice, including a smaller cingulate cortex, granular retrosplenial cortex, primary motor cortex and fimbria of the hippocampus.

RESUMO

UNLABELLED: Venous thromboembolism (VTE) is one of the most common complications in cancer patients. Although factor V Leiden (FVL) is the most common genetic defect causing thrombosis, the impact of gene abnormalities on thrombotic tendency in cancer patients remains poorly explored. Tissue factor (TF) is a major physiologic initiator of blood coagulation. This is the first study regarding the association of TF gene -603A/G and +5466A>G polymorphisms with VTE in malignancy. Materials and Me-thods: The study consists of two groups: cancer patients with VTE were included as Group 1 (n = 46); Group 2 comprises 196 cancer patients without VTE. Restriction fragment length polymorphism method was used for the detection of polymorphisms of TF -603A/G in the 5՛upstream region and TF 5466A/G in intron 2. FVL, PT G20210A and MTHFR C677T polymorphisms were determined by using commercially available Light Cycler kits. The genotype and allele frequencies between the groups were compared using χ2 or Fisher exact test, if appropriate. RESULTS: No differences were observed in the distribution of TF gene -603A/G genotype frequencies between the groups. Although a slightly increased incidence of +5466GA genotype was in Group 1 (17.4% vs 11.2%), it did not achieve statistical significance. The prevalence of FVL was significantly greater in Group 1 compared with Group 2 (41.3% vs 4.1%, p < 0.05). Difference in frequency of 677TT+CT (MTHFR) + 5466GG (TF) genotypes combination was found in women of two investigated Groups (p < 0.05). No differences were also in genotypes and allele frequencies of MTHFR C677T and PT G20210A between two Groups (p > 0.05). CONCLUSIONS: The present study did not show significant association of TF gene -603A/G and +5466A>G polymorphisms with VTE in malignancy, however, further larger studies including different ethnic population are needed to confirm our findings.

RESUMO

OBJECTIVE: Many older women are hesitated to initiate discussions about urinary symptoms and their incontinence. The aim of this study is to determine the prevalence of occult urinary incontinence in outpatient older women and to evaluate its association with other geriatric conditions. PATIENTS AND METHODS: 100 female patients 65 years and older were assessed at the geriatric outpatient clinic. The validated form of the Turkish version of the International Consultation on Incontinence Questionnaire-Short Form was used to evaluate urinary incontinence and quality of life. Comprehensive geriatric assessment including activities of daily living, instrumental activities of daily living, mini mental state examination and geriatrics depression scale was performed. The number of falls, comorbid conditions and number of medications were noted. The association between urinary incontinence and geriatric domains were evaluated with logistic regression analysis. RESULTS: A total of 100 patients were evaluated, 64 of them included in the study. The median age of patients was 72.5. The rate of urinary incontinence was found 40.6%. The association between urinary incontinence and quality of life, performance status and comorbidity was found statistically significant with logistic regression (p = 0.033, p = 0.005, p = 0.031 respectively). Half of the patients with UI believe that it is part of normal aging and no definite treatment is available. CONCLUSIONS: Occult urinary incontinence is a significant problem in older women that inversely affecting the quality of life. The study suggests that awareness and education regarding incontinence should be increased among elderly patients and screening of urinary incontinence is an important part of the geriatric assessment. The evaluation and management of functional status and comorbid conditions should be the initial step during incontinence management in elderly patients.

RESUMO

Neurofibromatosis type 1 (NF1) is an autosomal dominant hereditary neurocutaneous syndrome characterized by multi-system involvement and an increased incidence of both benign and malignant tumors. In this study, we evaluated the clinical presentation and prognosis of NF1 and malignancy. Between 1975 and 2013, 26 (5%) of the 473 patients with NF1 at our center developed non-neurofibroma neoplasms. The patient files of 26 subjects with tumors, other than optic glioma, were analyzed retrospectively to evaluate clinical features and treatment results. The age at diagnosis of NF1 ranged from 3 months to 16 years (median 5.5 years). The age range at tumor diagnosis was 1.5-33 years (median 8 years) in these 26 patients. The tumor histological subtypes included the following: 12 soft-tissue tumors (6 malignant peripheral nerve sheath tumors (MPNST), 5 rhabdomyosarcomas (RMS) and 1 malignant fibrous histiocytoma), 11 brain tumors (6 low-grade gliomas, 3 high-grade gliomas, and 2 medulloblastoma), 2 neuroblastomas and 1 non-Hodgkin's lymphoma. Twelve of 26 patients were alive at the time of the study. Although benign brain tumors with NF1 are more common, high-grade brain tumors also occur. Thus, careful and regular follow-up is crucial for early detection of malignancy in NF1 patients.

RESUMO

AIM: Objective of the present study was to investigate whether calcium antagonist use is associated with lower hemoglobin levels and/or higher erythropoiesis stimulating agent (ESA) requirement in hemodialysis patients. METHODS: A total of 130 adult hemodialysis patients were classified into two groups based on calcium antagonist usage for a period of at least 3 months as calcium antagonist users and calcium antagonist non-users. The two groups were compared cross-sectionally in a retrospective manner in terms of demographics, chronic kidney disease aetiologies, Charlson's Comorbidty Index, blood pressure, type of dialysis access, interdialytic body weight gain, cardiothoracic index, complete blood count, biochemistry, regular medication use and consumption of ESA. All independent variables that were different between the groups were subjected to logistic regression analysis. Linear regression analysis with dependent variable of hemoglobin value was also performed RESULTS: ESA consumption and blood pressure were higher, diabetic nephropathy, doxazosin and ACE inhibitor use were more frequent, and hemoglobin was lower in the calcium antagonist users. After logistic regression analysis, diabetic nephropathy, doxazosin use, ACE inhibitor use and lower hemoglobin were associated with calcium antagonist use. After lineer regression analysis, Age, BMI, gender, predialysis creatinine value, dialysis duration, systolic and diastolic blood pressure, doxazosin use, diabetes mellitus and diabetic nephropathy were not related with hemoglobin value. But, higher amount of ESA consumption, ACE inhibitor use and calcium antagonist use were significantly associated with lower hemoglobin value. CONCLUSION: CA use was associated with lower hemoglobin levels in our hemodialysis patient population.

RESUMO

AIM: Identification of patient with increased risk of cardiotoxicity would allow not only prevention and early diagnosis of chemotherapy related cardiotoxicity but also administration of optimal dose and duration of chemotherapy. MATERIALS AND METHODS: Fifty-two women with HER2(+) breast cancer treated with trastuzumab were included in this study. Patients were prospectively followed with routine cardiac evaluation. Before and after administration of trastuzumab blood samples for NT-proBNP were also taken. RESULTS: The median age was 48.5 year (range: 26-74). Hypertension and obesity were two most common co-morbidities. The median duration application of trastuzumab was 52 weeks. During median 14.5 (3-33) months follow-up cardiac adverse events occurred in 5 (9.6%) patients and 2 out of 5 was grade III-IV heart failure. Both patients had preserved left ventricular ejection fraction and no symptom of heart failure before trastuzumab but older than 65 years old and had diabetes mellitus and obesity. High level of NT-proBNP (> 300 ng/ml) was observed in both patients and heart failure recovery was not observed. There was statistically significant difference regarding body mass index (p = 0.004) and diabetes mellitus (p = 0.002) between patients with and without cardiotoxicity. CONCLUSION: Although, cardiac biomarkers still cannot replace routine cardiac monitoring, natriuretic peptides may provide additional tool for detection of patients with high risk of cardiotoxicity and early detection of cardiotoxicity.

RESUMO

BACKGROUND: Behçet disease (BD) is a chronic, multisystemic disease characterized by relapsing episodes of a wide spectrum of clinical symptoms. Several genetic and immunological factors have been suggested to be involved in the aetiopathogenesis of BD. AIM: To investigate the association between BD and five single nucleotide polymorphisms (SNP) in the gene for interleukin (IL)-23 receptor (IL-23R). METHODS: We recruited 123 patients with BD and 168 controls. A detailed phenotypic investigation of BD was made for each patient. Five SNPs in the IL-23R gene (rs11209026, rs7517847, rs11805303, rs1004819, rs17375018) were investigated. RESULTS: We found that patients with BD had a lower frequency of the rs17375018 GA and AA genotypes, and a higher frequency of the rs17375018 G allele, and these were statistically significant. The rs11209026 G allele frequency was higher in male patients with BD than in male controls, and the rs7517847 G allele was higher in patients with genital ulcers. The rs11805303 G and rs1004819 G alleles were more frequent in patients with papulopustular lesions. CONCLUSIONS: The rs17375018 variant in the IL-23R gene seems likely to be a strong susceptibility factor for BD in the Turkish population. As this variant was also shown to have a higher frequency in BD patients from different ethnic backgrounds in two previous studies, it may be specific for BD.

RESUMO

Breast cancer is the most common female malignant disease in the western countries where a woman's lifetime risk of developing the disease is more than 10%. Nulliparity or use of hormonal replacement therapy, strong family history, or a history of therapeutic thoracic radiation are considerable high risk factors for the development of breast cancer. Nowadays more new effective therapeutic agents have been developed for the intervention of the breast cancer, but prognosis is still remained poor in the metastatic disease. For the general population, screening mammography in women older than 40-45 years has been shown to be effective in identifying early-stage breast cancer and in decreasing the mortality rate. In randomized screening mammography trials for breast cancer, it has been established that screening mammograms reduced breast cancer mortality in women older than 50 years of age by 25 to 30%. This review article summarizes the risk factors for developing breast cancer, methods for risk assessment and the accepted screening guidelines.

RESUMO

According to the analysis on locally advanced breast cancer (LABC) from all breast cancer cases recorded in Surveillance Epidemiology and End Results database between the years 1992-1999 in the United States, the incidence of LABC were found to be 4.6% of all female breast cancers. Clinically, when breast cancer has advanced locoregionally but has not yet spread outside of the breast and regional lymph nodes, it is considered LABC. LABC includes breast cancers that have evidence of a large mass, involve the skin of the breast or the underlying muscles of the chest wall, and cancers that have infiltrated into the local lymph nodes. The prognosis of patients with LABC is relatively poor, with 5-year survival rates less than 50%. Because the incidence of LABC is very low, there are not many studies comparing neoadjuvant chemotherapy regimens in the literature. In management of LABC, initial therapy should be systemic neoadjuvant chemotherapy, aiming pCR. Anthracycline-based chemotherapy regimens are frequently recommended as the standard primary neoadjuvant chemotherapy for the treatment of LABC. Today, the optimal duration of neoadjuvant chemotherapy is unknown. Neoadjuvant endocrine therapy is considered an option for patients with hormone receptor-positive LABC. Ongoing clinical trials are now under way to evaluate the use of novel targeted agents in the neoadjuvant treatment of LABC.

RESUMO

PURPOSE: The role of genetic factors in the development of cancer is widely accepted. Data on the role of ABO blood group and Rh factor in breast cancer is inconclusive. The aim of this study was to investigate the presence of a possible association between HER2 (+) breast cancer in Turkish women and ABO blood groups and Rh factor. METHODS: In 294 female patients with HER2 (+) breast cancer, ABO blood groups and Rh factor were examined. The relationship of blood groups with age, menopausal status, and family history of cancer, estrogen receptor (ER), progesterone receptor (PR) and HER2 status of these patients was evaluated. Blood groups distribution of 22,821 healthy blood donors was also assessed and compared with the patients' blood groups distribution. RESULTS: The median patient age was 47 years (range 20-80) and 56% of the patients were premenopausal. ER and PR were positive in 50 and 60% of the patients, respectively. Overall, the ABO blood group distribution of the 294 HER2 (+) breast cancer patients was similar to that of the healthy blood donors (p=0.36). Likewise there was no correlation between blood type and ER, PR and menopausal status. Rh (-) patients had more frequent family cancer history and this difference was significant for patients with blood group B Rh (-) and O Rh (-) (p = 0.04). CONCLUSION: In the present study we didn't find any relationship between HER2 status and ABO blood group and Rh factor. However, further studies with larger number of patients are needed to establish the role (if any) of blood groups in patients with breast cancer.

RESUMO

This paper describes the design and performance of a new instrument to track temporal changes in physical parameters during the drying behavior of solutions, as well as curing of monomers. This real-time instrument follows in-plane and out-of-plane birefringence, weight, thickness, and surface temperature during the course of solidification of coatings and films through solvent evaporation and thermal or photocuring in a controlled atmosphere. It is specifically designed to simulate behavior of polymer solutions inside an industrial size, continuous roll-to-roll solution casting line and other coating operations where resins are subjected to ultraviolet (UV) curing from monomer precursors. Controlled processing parameters include air speed, temperature, initial cast thickness, and solute concentration, while measured parameters are thickness, weight, film temperature, in-plane and out-of-plane birefringence. In this paper, we illustrate the utility of this instrument with solution cast and dried poly (amide-imide)∕DMAc (Dimethylacetamide) solution, water based black paint, and organo-modified clay∕NMP (N-Methylpyrrolidone) solution. In addition, the physical changes that take place during UV photo polymerization of a monomer are tracked. This instrument is designed to be generic and it can be used for tracking any drying∕swelling∕solidification systems including paper, foodstuffs such as; grains, milk as well as pharmaceutical thin paste and slurries.

RESUMO

AIM: To evaluate the genetic, congenital and metabolic disorders which were detected concurrently with primitive neuroectodermal tumors (PNET) of the central nervous system in children. METHODS: Medical records of 1030 children who were admitted to our department with diagnosis of brain tumor between 1975 and 2005 were reviewed retrospectively. Medulloblastoma and supratentorial PNETs were detected in 289 patients. They were reviewed for associated metabolic conditions, genetic and congenital defects. RESULTS: One of the following conditions were detected in 10 patients with medulloblastoma and supratentorial PNETs: Neurofibromatosis type 1, Gorlin syndrome, juvenile polyposis coli, cancer prone syndrome of total premature chromatid separation and Fanconi anemia, bilateral retinoblastoma, L-2-hydroxyglutaric aciduria, Gilbert syndrome, gray platelet syndrome, cleft lip-palate and left renal agenesis. In the patients with multiple malignant diseases, cancer prone syndrome of total premature chromatid separation and Fanconi anemia, Gorlin syndrome and juvenile polyposis coli were diagnosed after diagnosis of the malignant tumors. Medulloblastoma was the first manifestation in the case with Gorlin syndrome. In case with retinoblastoma, pineal PNET was detected 2 months after diagnosis of retinoblastoma. Cleft lip-palate and L-2-Hydroxyglutaric aciduria were detected previously in the patients before their brain tumors whereas Gray platelet, Gilbert syndrome and left renal agenesis were diagnosed during treatment of medulloblastoma. CONCLUSION: Associated genetic, metabolic and congenital conditions were detected in 3.5% of the cases. Thus the patients with PNET should be followed for these defects.

RESUMO

PURPOSE: To study the efficacy and safety of radiotherapy (RT) with concomitant and subsequent temozolomide in comparison to RT alone in the treatment of patients with newly diagnosed glioblastoma multiforme (GBM) after brain surgical intervention. METHODS: Twenty patients received cranial fractionated RT (60 Gy total dose: 2 Gy/day, 5 days/week, for 6 weeks) with concomitant oral temozolomide (75 mg/m(2)/day x 7 days/ week, for 6 weeks) followed by temozolomide monotherapy (200 mg/m(2)/day × 5 days every 28 days for 6 cycles). Another 20 patients received only cranial RT (Co-60 teletherapy, 60 Gy in 30 fractions). RESULTS: At the end of the study the median time to progression free survival (PFS) was 13 months in the temozolomide plus RT treatment group and 5 months in the RT-alone group (p=0.0001). Median overall survival (OS) in the temozolomide plus RT and the RT-alone group was 19 and 11.5 months, respectively (p=0.0264). The main side effect in the temozolomide plus RT group was myelosuppression. Concomitant treatment resulted in grade 3 hematologic toxicity in 6 patients. CONCLUSION: These data show that the combination of temozolomide, concomitant and subsequent to RT seems more effective than RT alone in patients with newly diagnosed GBM and that multimodality treatment is safe and well tolerated.
