RESUMO

Background: The neuroendocrine system and the hypothalamic-pituitary-adrenal axis are among the possible neurobiological factors that may be involved in the emergence and persistence of post-traumatic stress disorder. Here, we determined the levels of vasopressin and oxytocin in the peripheral blood of people with post-traumatic stress disorder, investigating their correlation with post-traumatic stress disorder symptoms. Methods: The study included patients with post-traumatic stress disorder according to the Diagnostic and Statistical Manual of Mental Disorders Version 4 and healthy controls. People who accepted to participate in the study, who did not have any additional diseases, who had the ability to understand the questionnaires, and who did not use medications during the 3 months preceding the study onset were enrolled. The levels of vasopressin and oxytocin were measured using the enzyme-linked immunosorbent assay. Results: Twenty-eight subjects with post-traumatic stress disorder and 19 healthy controls were included. The 2 groups were not significantly different in terms of oxytocin blood levels (P = .481). However, subjects with post-traumatic stress disorder had a significantly lower vasopressin level than controls (P < .001). We found no significant correlations of trauma duration and scale scores with oxytocin or vasopressin levels. Conclusion: The findings of this study show that blood vasopressin may play a role in post-traumatic stress disorder. Prospective studies based on a larger number of participants are warranted to clarify how neuromodulators may affect the pathogenesis of post-traumatic stress disorder.

RESUMO

OBJECTIVES: Adipocytokines and oxidative stress (OS) are involved in the pathogenesis of both obesity and periodontitis. The aim of this study was to evaluate periodontal therapy outcomes in terms of serum and gingival crevicular fluid (GCF) levels of adipocytokines and OS markers in obese patients with periodontitis, in order to have an insight into the association between obesity and periodontitis. MATERIALS AND METHODS: A total of 39 patients (20 obese, 19 non-obese) with periodontitis were included in this study. Clinical periodontal parameters were assessed; serum and GCF levels of adipocytokines and OS markers were evaluated by ELISA at baseline and 3 months after non-surgical periodontal therapy. RESULTS: Significant improvements in clinical periodontal parameters were observed in both groups at 3 months (p < 0.01). While serum levels of TNF-α, leptin, and total oxidant status (TOS) in the obese group were higher at baseline (p < 0.01), leptin levels remained higher at 3 months despite a significant decrease (p < 0.01). Although NSPT improved GCF levels of total antioxidant status (TAS) and TOS in both groups, they were significantly different between the groups after therapy (p < 0.05). CONCLUSIONS: It seems that leptin, TNF-α, and TOS contribute to systemic inflammatory and oxidative state in patients with obesity. Despite improvements in clinical periodontal parameters, obesity might be a modulating factor in the development and progression of periodontal disease in terms of some adipocytokines and OS markers. CLINICAL RELEVANCE: Since the global burden of both obesity and periodontitis is continuously increasing, the management of these inflammatory diseases has become more important. The current study contributes to our understanding of the role of OS and adipocytokines on the relationship between obesity and periodontitis by response to periodontal treatment.

RESUMO

INTRODUCTION: Ischemia/reperfusion injury occurs after testicular torsion, levels of free oxygen radicals and inflammatory cytokines are increased in both the torsional and contralateral testis, leading to testicular injury. OBJECTIVE: The present study investigated whether orchiopexy or orchiectomy after testicular torsion was superior in terms of fertility potential in the long term. STUDY DESIGN: Following 720°, 4 h left testicular torsion, orchiectomy or orchiopexy was performed on 84 rats, which were then sacrificed and evaluated for testicular function at day 1, at 3 months and 6 months (n = 14 per group). An additional 14 rats were in the control group. RESULTS: Follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were significantly lower in the orchiopexy group than the orchiectomy and control groups after 3 months. However, there were no significant differences in hormone parameters among the three groups after 6 months. The hormone levels, Johnsen score, seminiferous tubule diameter, and inducible nitric oxide synthase (iNOS) expression at 3 and 6 months were not significantly different between the orchiectomy group and controls. Histopathological analyses at 3 and 6 months indicated significant decreases in Johnsen score and seminiferous tubule diameter in the ipsilateral testis in the orchiopexy group. At 3 months, the level of iNOS expression in the contralateral testis was significantly lower in the orchiopexy group than in other groups. At 6 months, however, it was not significantly different between the orchiopexy and control groups. There were no significant differences in iNOS expression at 3 or 6 months in the orchiectomy group compared to controls. DISCUSSION: The ipsilateral testis in the orchiopexy group began to atrophy at 3 months, and the degree of atrophy became more evident at 6 months. The level of iNOS expression was low in the bilateral testis at 3 months in the orchiopexy group, and sperm in the contralateral testis were not yet functionally healthy. The level of iNOS expression in the ipsilateral testis decreased further at 6 months in the orchiopexy group, while that in the contralateral testis returned to the normal level. CONCLUSION: Testicular functions were restored faster after orchiectomy compared to orchiopexy following testicular torsion. However, follow-up of the rats for 6 months demonstrated that orchiopexy or orchiectomy procedures conducted on the testicular torsion had no effect on future fertility potential after 4 h of torsion.

RESUMO

PURPOSE: This study was conducted to determine the prevalence and severity of postoperative pain in the first 24 hours after surgery and to emphasize the importance of postoperative pain assessment. DESIGN: A descriptive study. METHODS: This study was carried out on May 21, 2019 with 898 patients who had completed the postoperative 24th hour in the surgical clinics of 10 training and research hospitals in Istanbul, the capital of Turkey. Point prevalence was used in the study. Data were collected using a questionnaire developed by the researchers and the Revised American Pain Society Patient Outcome Questionnaire. Descriptive statistics were presented as frequency, percentage, mean, and standard deviation. Nonparametric tests were used for data without normal distribution (Kolmogorov-Smirnov Test, P < .05). Two-group comparisons were performed using the Mann-Whitney U test. The Kruskal Wallis-H test was used for the comparison of three or more groups. Statistical significance was set as P < .05. FINDINGS: The three main types of surgery were general surgery with 31.8%, gynecologic surgery with 12.9%, and orthopedic surgery with 12.7%. The mean lowest level of pain felt by the patients included in the study in the first 24 hours was 3.90 ± 2.94, and the mean highest level of pain was 6.38 ± 4.45. CONCLUSIONS: Postoperative pain is a subjective phenomenon and may be affected by factors such as type of surgery, previous experience of surgery, duration of surgery, the length of the surgical incision, the type of anesthesia, the quality of postoperative care, individual characteristics and experiences, and fear anxiety; thus, the experience of pain may vary from person to person.

RESUMO

OBJECTIVES: This prospective study aimed to compare changes in serum thiamine and pyridoxine levels of patients who underwent liver transplant or living donor hepatectomy. MATERIALS AND METHODS: Between January 2013 and November 2013, 35 patients with chronic liver disease who underwent liver transplant (the recipient group) and 30 healthy individuals who underwent living donor hepatectomy (the control group) during the same period were prospectively compared in terms of both preoperative and postoperative serum thiamine and pyridoxine levels. The groups were also subjected to intragroup analysis of preoperative and postoperative changes in serum vitamin levels to determine how a major surgical procedure affected serum vitamin levels. Mann-Whitney U test and Wilcoxon signed-rank test were used for intergroup comparisons and intragroup repeated measurements, respectively. RESULTS: The intergroup comparisons revealed significant differences in favor of the control group with respect to preoperative thiamine (P < .026) and postoperative thiamine (P < .017) levels, whereas there were statistically significant differences in favor of the recipient group with respect to the preoperative pyridoxine (P < .006) and postoperative pyridoxine (P < .001) levels. The intragroup comparisons showed significant increases in serum thiamine (P < .001) and pyridoxine (P < .031) levels compared with the preoperative serum levels of both vitamins at postoperative day 5 in the recipient group. In the control group, serum thiamine level (P < .001) at postoperative day 5 was significantly different from the preoperative level. On the other hand, a drop in serum pyridoxine level was detected at postoperative day 5, although this was not statistically significant (P < .21). CONCLUSIONS: This study showed a lower serum thiamine level but a higher serum pyridoxine level in patients with chronic liver disease versus healthy controls. This difference persisted into the early postoperative period. This study also showed significant increases in thiamine and pyridoxine levels after transplant surgery.

RESUMO

BACKGROUND: Androgenetic alopecia (AGA) is the most common type of hair loss and affects approximately 50% of the male population. AIMS: In the present study, to investigate microinflammation, perifollicular fibrosis, and oxidative stress in AGA cases, some serum biomarker levels were measured and evaluated. PATIENTS/METHODS: Serum samples were drawn from patients (n = 58) and control (n = 30) groups referring to Atatürk Training and Investigation Hospital Dermatology Outpatient clinic. In serum samples, NF-κB, TNF-α, TGF-ß1, thioredoxin, nitric oxide, TOS, TAS, and thiol disulfide homeostasis (native thiol, total thiol, disulfide) were measured and evaluated. RESULTS: In patients with AGA, NF-κB (P = .005), TNF-α (P = .008), TGF-ß1 (P = .028), thioredoxin (P = .004), nitric oxide (P < .001), and TOS (P < .001) serum levels were found to be significantly higher than those in control group, while TAS (P = .003), native thiol (P < .001), total thiol (P < .001), and disulfide (P < .001) serum levels were found to be significantly lower. CONCLUSIONS: According to the results of the present study, it was concluded that in that AGA androgens lead to oxidative stress by increasing free oxygen radicals, which accelerates hair loss by causing microinflammation and fibrosis. The recognition of the effect of androgens and associated factors on the hair follicle cycle is essential for the development of new and effective treatment methods.

RESUMO

The aim of this study was to investigate whether overactive bladder (OAB) influences hip fractures in climacteric women by comparing the frequency of OAB and nocturia symptoms in patients with hip fractures and their age-matched controls in pre-fracture period. A total of 30 climacteric patients with a history of hip fracture were compared to a control group of 51 women in terms of OAB, nocturia and nocturia-QoL. A questionnaire composed of structured questions and Turkish validated versions of the specific questionnaires for OAB, OAB-Quality of Life (OAB-q) and nocturia-QoL was directed to the two groups. We did not detect statistically relevant differences between the groups for the presence or severity of OAB and OAB-q (p > .05). However, Nocturia-QoL was worse in the group with hip fracture (p = .022). Overactive bladder has no contribution to the overall risk of hip fracture, whereas, the severity of nocturia seems to play a role as a risk factor in the formation of hip fracture. Impact statement What is already known on this subject: Hip fracture is associated with high morbidity, mortality and the cost. Prevention of hip fracture is a high priority for the patients, physicians and the public health. Several studies and consensus opinions have investigated the risk factors for the hip fractures. What the results of this study add: Although urinary symptoms were not evaluated in previous studies as a risk factor, desire of urination makes people stand up and move to their toilet, and may put them in a hurry if it is sudden and uncontrollable one. Therefore, we hypothesised that overactive bladder (OAB) and nocturia may be a risk factor in the formation of hip fractures. Our study showed that Nocturia Quality of Life is worse in patients with the hip fracture. Therefore, overactive bladder may not have a role on the overall risk of hip fracture, but the severity of nocturia seems as a risk factor in the fracture process. What the implications are of these findings for clinical practice and/or further research: The getting up from the bed would probably be harder than getting up from a chair in elderly, and life style modifications such as illumination bedroom and organisation of living place may be helpful to minimise the risks.

RESUMO

OBJECTIVE: Trichomoniasis is a parasitic infection that occurs with the settlement of Trichomonas vaginalis in female and male urinary and reproductive tracts. This infection is generally asymptomatic in males, and males are thought to be a carrier for the transmission of infection. In this study, our aim was to detect trichomoniasis using nested polymerase chain reaction among males who were referred to a hospital with suspected urinary tract infection. METHODS: Urine samples were collected from 138 male patients between 18 and 50 years of age who were referred with suspected urinary system infection to the Urology Outpatient Clinic at Malatya University Medical Center Malatya between December 2013 and May 2014. Direct microscopy, two different culture methods, and nested Polymerase chain reaction (PCR) were performed for the investigation of T. vaginalis in urine samples. RESULTS: Urinary tract infection was diagnosed in 47 of the 138 patients according to white and red blood cell counts in the urine samples. T. vaginalis infection was detected in 6.5% (9/138) of the suspected patients by nested PCR, while none of the samples tested positive by direct microscopy and culture examinations. Statistical significance was found between infection of the urinary tract and nested PCR positivity for T. vaginalis. CONCLUSIONS: According to our results, nested PCR is the most sensitive method for the detection of trichomoniasis in male patients. We strongly recommend using nested PCR for the differential diagnosis of urinary infections in males.

RESUMO

OBJECTIVE: Schizophrenia is a chronic psychotic disorder in which genetics and environmental factors such as infection and the corresponding immune response play a role in the etiopathogenesis. The aim of this study was to compare some immune factors such as nuclear factor-B (NF-B) activation, myeloperoxidase (MPO), the anti-inflammatory cytokine interleukin-4 (IL-4), and regulatory cytokine transforming growth factor- (TGF-) in schizophrenia patients and an age- and gender-matched control group. METHOD: Plasma levels of IL-4, TGF-, MPO, and NF-B activation in 20 subjects with treatment-resistant schizophrenia and 20 age- and gender-matched healthy controls were analyzed. Disease severity was evaluated using the Brief Psychiatric Rating Scale (BPRS). RESULTS: Plasma TGF- levels were found to be significantly lower and NF-B to be significantly higher in antipsychotic treatment-resistant schizophrenia patients than in controls in this study. No significant differences were found between the patient and control groups for serum IL-4 and MPO levels. CONCLUSION: The low TGF- level in treatment-resistant schizophrenia patients in the symptom exacerbation period indicates that there is inadequate Th1/Th2 balance. Large-scale studies are required to investigate whether this is responsible for resistance in schizophrenia. The fact that the increase in NF-B that we found in treatment-resistant schizophrenia patients in this study has also been reported in the first attack in untreated schizophrenia patients in previous studies indicates that NF-B plays a role in the disorder's physiopathology from the beginning.

RESUMO

The aim of this study was to determine the frequency of haemostatic abnormalities in women with menorrhagia and to evaluate their effect on quality of life (QoL). The study population was composed of patients with menorrhagia seen in the outpatient clinic, having a score of >185 with a pictorial blood assessment chart. Structured questionnaires were used in the assessment of demographic characteristics and QoL, and patients were tested for bleeding disorders. Ninety women were recruited for the study. Bleeding disorders were detected in 40% of them: 11.1% had von Willebrand disease, 2.2% had low von Willebrand factor and 26.7% had platelet function disorders (PFD). In 22 (91.6%) cases with PFD the, defect was non-specific and impaired aggregation response to ristocetine (37.5%) was the most commonly detected problem. Bleeding disorders were not associated with any significant reduction in QoL (p > .05). Hereditary bleeding disorders may be the cause of unexplained menorrhagia even in the middle-aged women, but they had no prominent effect on QoL.

RESUMO

OBJECTIVE: To investigate the effect of a previous IVF failure on the quality of life and emotional distress, in couples undergoing IVF treatment. Experiencing IVF failure might cause differences on the anxiety-depression and quality of life scores of the couples, compared to the ones who were undergoing IVF treatment for the first time. STUDY DESIGN: This study included 64 couples who had previously experienced at least one IVF failure (Group 1) and 56 couples without history of IVF failure (Group 2) in a private Assisted Reproductive Center, Istanbul, Turkey. A sociodemographic data form, the FertiQoL International and Hospital Anxiety (HAD-A) and Depression scale (HAD-D) for evaluating the status of distress, were administered for the study. RESULT(S): FertiQoL scores were compared between the groups, the environment scale of the quality of life in treatment section was found to be significantly higher in Group 1 compared with Group 2 (p=0.009). The HAD-A and HAD-D scores did not differ significantly between the groups. Group-variables were investigated using multilevel analysis, the infertility duration and income level were found to have an effect on the subscales of quality of life (p=0.009 and p=0.001 respectively) in Group 2. Depression scores were higher in couples with infertility duration of below five years in Group 1 and Group 2 compared to couples with infertility duration of five years or above (MANOVA analysis). The level of education was found to affect the scores of HAD-D in Group 2, but not in Group 1 (p=0.011). The score of HAD-D was significantly affected by the family type only in Group 2 (p=0.009); the depression score of the couples living with a nuclear family was found to be higher compared with the couples living in a traditional family (p=0.021). CONCLUSION(S): Fertility-specific quality of life scores reveals better results regarding the orientation to the treatment environment in the couples with a previous IVF failure, compared to first IVF cycle couples. Treatment failure does not elevate the level of anxiety, while the effect on depression scores changes according to duration of infertility.

RESUMO

PURPOSE: To evaluate lenticular oxidative stress in rat menopausal models. METHODS: Forty Wistar female albino rats were included in this study. A total of thirty rats underwent oophorectomy to generate a menopausal model. Ten rats that did not undergo oophorectomy formed the control group (Group 1). From the rats that underwent oophorectomy, 10 formed the menopause control group (Group 2), 10 were administered a daily injection of methylprednisolone until the end of the study (Group 3), and the remaining 10 rats were administered intraperitoneal streptozocin to induce diabetes mellitus (Group 4). Total oxidant status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI) measurements of the crystalline lenses were analyzed. RESULTS: The mean OSI was the lowest in group 1 and highest in group 4. Nevertheless, the difference between the groups was not statistically significant in terms of OSI (p >0.05). The mean TOS values were similar between the groups (p >0.05), whereas the mean TAC of group 1 was significantly higher than that of the other groups (p <0.001). CONCLUSIONS: Our results indicate that menopause may not promote cataract formation.

RESUMO Objetivo: Avaliar o estresse oxidativo lenticular em modelos de ratas na menopausa. Métodos: Quarenta ratos albinos femininos tipo Wistar foram incluídos neste estudo. Trinta ratas foram submetidas à ooforectomia para gerar o modelo de menopausa e 10 ratas formaram o grupo controle (Grupo 1). Dentre as ratas ooforectomizadas, 10 formaram o grupo controle menopausa (Grupo 2), 10 ratas receberam injeção diária de metilprednisolona até ao final do estudo (Grupo 3) e 10 ratas receberam estreptozotocina por via intraperitoneal para induzir diabetes mellitus (Grupo 4). O estado oxidante total (TOS), a capacidade total antioxidante (TAC) e as medições do índice de estresse oxidativo (OSI) dos cristalinos foram analisados. Resultados: A média de OSI foi menor no grupo 1 e maior no grupo 4. Todavia, a diferença entre os grupos não foi estatisticamente significativa (p>0,05). Os valores médios TOS foram semelhantes entre os grupos (p>0,05), enquanto a média de TAC grupo 1 foi mais elevada do que nos outros grupos ( p<0,001). Conclusões: Nossos resultados indicam que a menopausa podem não promover a formação de catarata.

RESUMO

BACKGROUND: At present, the rates of breast cancer are continuously increasing, with over a million new cases being diagnosed worldwide each year. Hence, the development of new breast cancer chemopreventive drugs with acceptable efficacy and toxicity that are suitable for use for a protracted period of time is urgently needed. The present study investigated the potential preventive effects of zoledronic acid [ZOL] and radiotherapy [RT], both alone and in combination, on precancerogenic changes on the breast tissues of females. MATERIALS AND METHODS: Wistar rats were treated with 7,12-dimethylbenz [a] anthracene [DMBA] at the acute phase. Fifty female rats were divided into seven groups: Control group [I]; ZOL, group [II]; RT, group [III]; DMBA, group [IV]; DMBA + RT, group [V]; DMBA + ZOL, group [VI]; and DMBA + ZOL + RT, group [VII]. RESULTS: The treatment of DMBA-exposed rats with ZOL and RT, both alone and in combination, successfully upregulates the transcriptional levels of Bax, caspase-3, caspase-9, p21, and BRCA 1 in mammary tissues, which may account for the elevated apoptotic activities observed and the eventual inhibition of tumor growth. The administration of RT and ZOL both alone and in combination was found to be effective for inhibiting the DMBA-induced precancerogenic changes on breast tissues and modulating the expression of apoptosis-associated proteins in the acute phase. CONCLUSIONS: The combination of RT and ZOL was more effective than either agent alone. Our results suggest that the administration of ZOL and irradiation in combination can offer maximal protection against DMBA-induced mammary precancerogenic changes.

RESUMO

OBJECTIVE: We aim to evaluate and describe the tissue elasticity characteristics of various ovarian lesions with sonoelastography. METHODS: 35 patients (age range 16-85 years; mean age 40.8 years) underwent sonoelastography and later MRI. Histopathological confirmation of all lesions was carried out, except eight of endometriomas and six of septated cysts which were confirmed on MRI and follow-up ultrasonography. Strain ratios and elastogram patterns were recorded. Lesions were classified into three groups (Group 1: cystic lesions, Group 2: benign tumours and Group 3: malignant lesions) and findings were compared between groups for both observers. Interobserver agreement was analyzed. Optimal cut-off values for strain ratios were achieved with receiver operating characteristic curve analysis. RESULTS: Ovarian endometriomas and complex cystic lesions were observed hard on elastograms with high strain ratios, and malignant lesions were observed mostly soft with very small strain ratios. Benign tumours had average tissue stiffness, observed harder than the malignant lesions, and strain ratios ranged from 4 to 14. The differences in patterns and strain ratios between groups were statistically significant (p < 0.05 for both observers). CONCLUSION: Our study revealed that malignant ovarian lesions have softer tissue property than benign lesions and cystic lesions in terms of elastogram patterns and strain ratios. ADVANCES IN KNOWLEDGE: Most ovarian lesions contain solid and cystic parts which make the malignant and benign lesions look similar on imaging modalities. Using real-time sonoelastography as an adjunct to other imaging modalities may improve the differentiation of malignant ovarian lesions from benign lesions.

RESUMO

INTRODUCTION AND HYPOTHESIS: Steroid soaking may decrease mesh-triggered inflammatory reaction in tissue. We aimed to investigate the tissue reaction to a steroid-soaked mesh material and an unsoaked mesh material in the rat model. METHODS: Neutral and steroid-soaked type I macroporous polypropylene (PP) monofilament and polyvinylidene fluoride (PVF) mesh materials were implanted on the rectus abdominis muscle of 20 mature Wistar albino rats. Animals were divided into four groups: PP mesh with steroid (PP-S), PP mesh without steroid, PVF mesh with steroid (PVF-S), and PVF mesh without steroid. The rats were killed after 12 weeks, and histologic, immunohistochemical and electron microscopic examinations were performed. For immunohistochemical analysis, polyclonal rabbit anti-mouse CD3, rabbit anti-mouse CD68, rabbit anti-mouse CD15, and rabbit anti-mouse CD34 antibodies were used for the detection of lymphocytes, macrophages, polymorphonuclear leukocyte foreign body giant cells, and fibromyocyte stem cells, respectively. Samples were stained with hematoxylin and eosin for the histologic evaluation of inflammation and with Masson's trichrome stain for the evaluation of collagen deposition. Pore size and mesh ultrastructure were evaluated by electron microscopy. RESULTS: Expression of CD3 was lower in the PVF, PVF-S and PP-S groups, and expression of CD34 was higher in the PVF-S and PP-S groups than in the PP groups (p < 0.05). Collagen deposition was lower in the PVF, PVF-S and PP-S groups (p < 0.05). Histologically, the intensity of inflammation was lower in the PVF-S and PP-S groups than in the PP mesh group (p < 0.05). There were no significant differences among the groups in terms of pore size and mesh ultrastructure on electron microscopic examination (p > 0.05). CONCLUSIONS: PVF mesh induces less inflammation than PP mesh, and in both mesh types steroid soaking further decreases inflammation without changing the pore size.

RESUMO

OBJECTIVE: To investigate the healing effects of erythropoietin (EPO) and stem cells (SCs) in traumatic brain injury (TBI). METHODS: Twenty-nine Wistar albino rats were used and separated into the following groups: control (C), EPO, SC, and SC+EPO. Group C received a TBI only, with no treatment. In the EPO group, 1000 U/kg EPO was given intraperitoneally at 30 minutes after TBI. In SC group, immediately after formation of TBI, 3 × 10,000 CD34(+) stem cells were injected into the affected area. In the SC+EPO group, half an hour after TBI and the injection of stem cells, 1000 U/kg EPO was injected. Before and after injury, trauma coordination performance was measured by the rotarod and inclined plane tests. RESULTS: Seven weeks after trauma, rat brains were examined by radiology and histology. Rotarod performance test did not change remarkably, even after the injury. Compared with group C, the SC+EPO group was found to have significant differences in the inclined plane test results. CONCLUSIONS: Separately given, SCs and EPO have a positive effect on TBI, and our findings suggest that their coadministration is even more powerful.

RESUMO

OBJECTIVES: Electroconvulsive therapy (ECT) is the most effective option for several psychiatric conditions, including treatment-resistant schizophrenia. However, little is known about the molecular mechanism of action of ECT. The link between inflammatory system and schizophrenia is the focus of recent studies. However, the impact of ECT on inflammatory functioning in this disorder remains elusive. Whether ECT could modulate inflammatory factors in patients with schizophrenia was examined. METHODS: Plasma levels of interleukin-4 (IL-4), transforming growth factor-ß (TGF-ß), myeloperoxidase (MPO), and nuclear factor-κB (NF-κB) activation were analyzed in 20 schizophrenic patients, mainly with resistant to antipsychotic medication disorders, and in 20 sex- and age-matched healthy controls. Disease severity was evaluated using the Brief Psychiatric Rating Scale. All patients were followed with measurement of the inflammatory factors before and after ECT treatment and compared with the controls. RESULTS: Patients with schizophrenia had markedly raised NF-κB and but decreased TGF-ß levels compared with healthy controls. On the other hand, no significant differences were found for the levels of IL-4 and MPO levels. The clinical improvement during repeated ECT was accompanied by a gradual and significant increase in IL-4 and TGF-ß level, but MPO and NF-κB activation were left unaffected. Increases in TGF-ß were negatively correlated with the change in Brief Psychiatric Rating Scale scores after ECT. CONCLUSIONS: It is shown that ECT, while increasing the anti-inflammatory response such as the levels of IL-4 and TGF-ß, it did not affect the levels of MPO and NF-κB activation in this study.

RESUMO

OBJECTIVE: To investigate ways of coping with stress in infertile men and women. STUDY DESIGN: The study population was composed of 255 women and 238 men (total, 493) admitted to an infertility clinic between May 2012 and December 2012. A questionnaire was used to gather information and the Ways of Coping inventory was used for the evaluation of patients. RESULTS: The mean age of the study population was 28.33 ± 5.59 (mean ± SD) for females and 31.60 ± 5.64 for males. We found similar coping scores for men and women in all subscales (Self-confident, Desperate, Obedient, Optimistic, Social Support Seeking) (p > 0.05). The variables affected Coping with Stress Scores in a similar way for both women and men except for "age" and "the desire for psychological support." The Optimistic approach score was worse in men over age 35 and better in those desiring psychological support in both sexes (p < 0.05). CONCLUSION: Infertile men and women use similar coping strategies and have similar coping scores. They mainly use active strategies at a moderate level. Increasing age in the male group, and lack of desire for psychological support in both sexes, are the factors negatively affecting the Optimistic approach scores.
