CIRCULATING MIR-132, MIR-146A, MIR-222, AND MIR-320 EXPRESSION IN DIFFERENTIAL DIAGNOSIS OF WOMEN WITH POLYCYSTIC OVARY SYNDROME.

Purpose: The aim of the study was to investigate whether the circulating miR-132, miR-146a, miR-222, and miR-320 levels are used in the differential diagnosis of women with polycystic ovary syndrome (PCOS) and healthy women. Methods: This prospective case-control study included 50 women with PCOS and age- and body mass index- matched 50 healthy controls. The hormone and lipid profiles, levels of microRNAs (miRNAs), and parameters of carbohydrate metabolism were measured. Results: Expression levels of miRNAs were assessed using the two-step quantitative real-time polymerase chain reaction. Circulating miR-132, miR-146a and miR-222 levels were significantly downregulated in the PCOS group compared with the control group. The miR-320 levels did not differ between the two groups. Free testosterone was negatively correlated with miR-132, miR-146a and miR-222. Insulin was negatively correlated with miR-132 and miR-146a. Conclusions: The results of the study revealed that miRNA expression, may suggest a possible distinction between healthy women and PCOS patients. miR-132, miR-146a, and miR-222 may have key functions in the pathogenesis of PCOS.

Interleukin-6 and C-reactive protein load in pre-storage and post-storage white blood cell-filtered red blood cell transfusions in premature infants.

OBJECTIVE: Leukocyte contamination during blood transfusion can cause many adverse effects. Filtration can be performed either at bedside during the transfusion or as pre-storage filtration. Pre-storage filtration is superior to bedside filtration because leukocytes are removed prior to storage, thus preventing further adverse effects associated with the storage of these cells. METHODS AND MATERIALS: One hundred and six infants were randomised into two groups: pre-storage filtration (group 1, n = 53) and bedside filtration (group 2, n = 53). C-reactive protein (CRP) and interleukin-6 (IL-6) levels were analysed within 24 h prior to the transfusion and 24 h after completion of the transfusion. RESULTS: In group 1, pre-transfusion median CRP and IL-6 levels were 2·95 (0·73-10·25) mg L(-1) and 8·59 (3·45-20·55) pg L(-1) , respectively, and post-transfusion median CRP and IL-6 levels were 2·28 (0·44-12·87) mg L(-1) and 6·62 (2·18-27·87) pg L(-1) , respectively. In group 2, pre-transfusion median CRP and IL-6 levels were 1·30 (0·40-7·84) mg L(-1) and 4·40 (2-17·12) pg L(-1) , respectively, and post-transfusion median CRP and IL-6 levels were 3·50 (0·50-7·85) mg L(-1) and 8·30 (3·48-23·75) pg L(-1) , respectively. There were no differences between pre-storage and post-storage leukoreduction average IL-6 and CRP levels in either group (P > 0·05 for both). Packed red blood cell (PRBC)-related necrotizing enterocolitis was detected in one infant in group 2. CONCLUSIONS: Because leukocytes in PRBC transfusions can be associated with many undesirable effects, leukoreduction is the best choice to prevent those effects. However, this method is still controversial. We demonstrated that using pre-storage and post-storage leukoreduction methods in erythrocyte transfusions did not change CRP or IL-6 levels, which are indicators of acute-phase response.

Does tamoxifen citrate prevent pulmonary fibrosis due to silica inhalation?

BACKGROUND: As shown in several studies, besides being used in breast cancer, tamoxifen is also known for its antifibrotic effects via reducing the serum TGF-beta levels. We investigated the possible preventive effect of tamoxifen in rats exposed to silica particles depending on the antifibrotic effect. MATERIALS AND METHODS: A total of 102 adult female Wistar Albino rats were divided into five groups. First two groups (control and tmx) were free of silica and the last three groups (slc, tmx1 and tmx 10) were exposed to crystalline silica. The rats in tmx, tmx1 and tmx10 groups received 10 mg/kg, 1 mg/kg and 10 mg/kg of body weight tamoxifen, respectively. On day 84, all rats were sacrified and tissue samples were obtained together with blood samples. The differences in serum TGF-ß levels, histological grades of fibrosis and inflammation in the lung and liver tissues together with addional biochemical markers were calculated between the groups. RESULTS: Silicosis occurred in slc, tmx1 and tmx10 groups in 100%, 91.7% and 52.1%, respectively. Liver fibrosis did not occur. The highest mean lung fibrosis scores were obtained in slc group while the scores were lower in tmx1 group and the lowest in tmx10 within silica-exposed rats. Nevertheless, the inflammation scores were higher in tamoxifen-administered rats in a dose-dependent pattern. CONCLUSION: Silica inhalation did not result in liver fibrosis. Tamoxifen is found to prevent lung fibrosis and reduce serum TGFß-1 levels while increasing lung inflammation (Tab. 3, Fig. 3, Ref. 27).

Comparison of maternal and umbilical cord blood soluble lectin-like oxidized low-density lipoprotein receptor 1 levels in early- and late-onset preeclampsia.

BACKGROUND: The main purpose of this study was to determine the maternal and umbilical cord blood oxidized LDL (oxLDL) and soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) levels in early- and late-onset preeclampsia (PE). MATERIALS AND METHODS: A case-control study was conducted in pregnant women with early-onset (before 34 weeks' gestation n = 19) and late-onset (after 34 weeks' gestation n = 22) PE compared to healthy normotensive pregnant controls (n = 44). Groups were compared for the maternal and umbilical cord plasma oxLDL and serum sLOX-1 levels. RESULTS: The mean maternal and umbilical cord serum sLOX-1 and plasma oxLDL levels were significantly increased in early- and late-onset PE compared to controls (p < 0.001). When early- and late-onset PE women were compared with serum sLOX-1 levels, the increase was more pronounced in early PE (p < 0.001). However, same comparison is not statistically significant in cord blood for oxLDL where as it is significantly higher in maternal blood for oxLDL in early-onset PE group. Maternal and cord blood oxLDL and sLOX-1 levels are positively correlated with each other; however, they are negatively correlated with fetal weight and gestational age. CONCLUSIONS: According to our results, maternal and umbilical cord blood levels of oxLDL and sLOX-1 were higher in preeclamptic pregnant. Thus, for the first time it has been shown that oxLDL and sLOX-1 levels were higher in fetal circulation as well as plasma of preeclamptic pregnant. However, sLOX-1 levels seem to be more implying than oxLDL for the differentiation of early and late preeclampsia.

Case report: partial trisomy 4q27q35 syndrome.

Partial trisomy 4q is a rare chromosomal abnormality which results in variable clinical features, often including growth and developmental delay, mental retardation and dysmorphic features. We herein report a newborn with the diagnosis of partial trisomy 4q with Hirschsprung's disease who was monitored in neonatal intensive care unit. This is the first report of partial trisomy 4q27q35 with accompanying Hirschsprung's disease.

Effect of hyperbaric oxygen in hepatopulmonary syndrome: an innovative experimental study.

OBJECTIVE: This study aimed to analyze the effect of hyperbaric oxygen treatment (HBOT) in hepatopulmonary syndrome (HPS). MATERIALS AND METHODS: Five-month-old female Wistar-Albino rats were randomly divided into three groups: Group I, the control group; Group II, the cirrhosis group; and Group III, the cirrhosis group + HBOT group. Rats were exposed to HBO sessions (2.4 atm./60 min) for 20 days. Animals were sacrificed 24 hours after the last HBO session. Biochemical analysis, oxygenation parameters, NO and NO synthase (NOS) levels, histopathological changes in the liver and lungs, and pulmonary artery diameter were measured. RESULTS: A total of 24 rats (10 rats were included in Group I, six rats in Group II, and eight rats in Group III) weighing 220-250 g were included in the study. Significant differences were observed for NO and NOS (9.10±1.05 to 12.17±1.85 µmol/L, p<0.05 and 0.46±0.31 to 1.17±0.39 U/ml, p<0.05, respectively) at baseline and day 36 only in group II. Inflammatory cell infiltration and bronchial injury were significantly increased in group II compared to group I (p=0.007 and p=0.008, respectively) but not in group III (p=0.266 and p=0.275, respectively). Pulmonary artery diameter was significantly lower in group III compared with group II at all sites in both lungs (p<0.05). CONCLUSIONS: HBOT may be a promising treatment for HPS by reducing NO and NOS activity, perialveolar arteriolar dilation, lung inflammation, and injury and guiding future clinical trials.

Young population bladder neoplasms.

OBJECTIVE: Bladder urothelial carcinoma is a rare condition that primarily affects the elderly and is rare in people under 40 years of age. There is no definitive information about the prognosis and clinical behavior of bladder cancer in young individuals. In our study, we aimed to investigate the prognosis and clinicopathological features of bladder tumors in patients under 40. PATIENTS AND METHODS: A retrospective analysis was performed on patients diagnosed with urothelial neoplasia who underwent bladder surgery between January 2008 and December 2020. The patient's medical records in our cancer database were collected. The study included stage, grade, multifocality, smoking habits, recurrence, and survival. The cases were divided into two groups: those under 40 (Group 1) and those over 40 (Group 2). The clinical and pathological features of young and old patients were compared. RESULTS: 17 patients (14 men and 3 women) under 40 were identified. The age ranged between 19 and 40, and the average was 30.6. One infiltrating urothelial carcinoma (pT1), twelve papillary urothelial carcinomas (pTa), two papillary urothelial neoplasias with low malignant potential, and two urothelial papillomas were all identified by pathology. Dysuria was the primary symptom that initially manifested. Recurrence occurred in two of 12 patients with low-grade papillary urothelial carcinoma in the young patient group. In a similar group of patients over 40, recurrence was detected in 7 out of 10 patients. Patients with urothelial carcinoma under the age of 40 have been noted to have single, small tumors, unlike older patients. No tumor progression was detected in young patients. All young patients are still alive and have not experienced any recurrences. In the group of older patients, tumor progression was observed in 11 patients (16.4%). CONCLUSIONS: Patients under 40 typically have low-grade and low-stage bladder urothelial cancer. Because urothelial tumors in young people frequently have a good prognosis and seldom recur, transurethral excision is the preferred treatment method for bladder tumors.

Does onlay mesh placement in emergency laparotomy prevent incisional hernia? A prospective randomized double-blind study.

PURPOSE: The objective of this study is to assess the effectiveness and safety of onlay mesh closure of emergency midline laparotomy to prevent incisional hernia. METHODS: This is a prospective randomized double-blind study and was carried out in the General Surgery Clinic, Konya City Hospital, from August 1, 2020 to August, 1, 2021. The study included 108 patients who were randomly grouped in 2 groups: patients with conventional abdominal closure and closure using additional onlay mesh (1:1). The follow-up period was for a year. The primary outcome was the incidence of incisional hernia and secondary outcomes were clinical data like complications, hospital length of stay, re-operations. RESULTS: It was observed that incisional hernia was present in 14 patients (27.4%) in conventional abdominal closure group and was in 2 patients using mesh (4%), (p = 0.001). Clavien-Dindo 3B complications were in rise in conventional closure group (p = 0.02). Of all complications, burst abdomen was significantly more common in conventional closure group (p = 0.04). The rate of surgically treated complications were higher in conventional closure group (p = 0.02). Clavien-Dindo 3A complications were more common in patients with contaminated wound in mesh group (p = 0.02). CONCLUSION: The use of mesh while closing the abdomen in emergency midline laparotomy reduces the risk of incisional hernia. Thus, to lower the risks of incisional hernia and its complications, prophylactic mesh can be used in high-risk patients.

Congenital mirror hand deformity.

Ulnar dimelia or commonly called mirror hand is a rare congenital anomaly of upper extremity characterized by duplication of ulna, absence of the radius with symmetrical polydactyly. This anomaly may be associated with shoulder dislocation, fibular dimelia, idiopathic scoliosis, cirrhosis, pyloric hypertrophy or polycystic kidney. We report a new case of this rare congenital anomaly which was not associated with any other malformation.

The role of laparoscopic sleeve gastrectomy on inflammatory parameters in morbidly obese patients.

BACKGROUND: Obesity is an excessive increase in body fat mass and triggers chronic inflammation which causes increased fat accumulation in the visceral fat tissue. The aim of this study was to analyze serum zinc (Zn), Zn-alpha 2 glycoprotein (ZAG), peroxisome proliferator-activated receptor-γ (PPAR-γ) and nuclear factor kappa-light-chain-enhancer of activated B cell (NF-κB) levels in morbidly obese patients before and after laparoscopic sleeve gastrectomy (LSG) and determine the association between alteration in body mass index (BMI), the % Excess Weight Loss (% EWL) and the biochemical parameters. METHODS: Thirty healthy individuals as a control group and 30 morbidly obese patients who had undergone LSG were enrolled in this study. Routine anthropometric and laboratory biochemical parameters in venous blood samples of groups at baseline and 1 and 12 months after LSG were recorded. RESULTS: Significant weight loss was achieved at 1 and 12 months after LSG. At baseline serum ZAG and PPAR-γ levels were lower, while NF-кB levels were higher in morbidly obese patients compared with the control group. Serum ZAG and PPAR-γ levels increased while NF-кB levels decreased 1 month and 12 months after LSG. Decreased %EWL was negatively correlated with changes in NF-кB, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), fasting plasma glucose and insulin at 12 months after LSG in morbidly obese patients. However, %EWL was positively correlated with changes in ZAG. CONCLUSIONS: Obesity was associated with down-regulated serum ZAG and PPAR-γ levels while up-regulated serum NF-кB. Our findings suggest that LSG ameliorates upregulating PPAR-γ expression, thereby inhibiting NF-κB-mediated inflammation by weight loss.

Factors associated with neurodevelopmental impairment in preterm infants with bronchopulmonary dysplasia.

OBJECTIVE: Bronchopulmonary dysplasia (BPD) is a common and serious complication in preterm infants with very low birth weight and is known to lead to poor neurodevelopmental outcomes. This study aimed to identify factors associated with neurodevelopmental impairment (NDI) in patients with moderate to severe BPD. SUBJECTS AND METHODS: A total of 83 preterm infants born between 24- and 29-weeks' gestation who were admitted to the neonatal intensive care unit and developed moderate/severe BPD between 2013 and 2017 were retrospectively evaluated. Developmental assessment was performed at 18 to 24 months of corrected age using the Bayley Scales of Infant Development II (BSID-II). Patients with NDI (n=41) and without NDI (n=42) were compared. RESULTS: BSID-II Mental Development Index and Psychomotor Development Index scores were 87±11 and 83±8 in the non-NDI group and 57±12 and 52±8 in the NDI group, respectively (p<0.001). The NDI group had significantly lower birth weight (847±174 vs. 1012±192 g) and gestational age (26.1±1.3 and 27.6±1.6 weeks) compared to the non-NDI group (p<0.001). Intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity, exposure to steroids, duration of respiratory support, and length of hospital stay were significantly higher in the NDI group (p<0.001). CONCLUSIONS: Many of the conditions in this study were found to be associated with poor neurodevelopmental outcomes in patients with BPD, such as prolonged respiratory support, prolonged hospitalization, intraventricular hemorrhage, retinopathy, and steroid therapy, can be avoided or prevented with strict protocols and prevention strategies. Appropriate management of comorbid risk factors may help prevent poor neurodevelopmental outcomes.

A case of schistosoma reflexum in a cat with chromosomal aberrations.

A 2-year-old, female Persian cat was presented with a history of distocia. In her first pregnancy, she had whelped four kittens and had eaten all of them right after parturition. She had mated again with the same tomcat. Well-developed foetuses with weak foetal heart beats were observed in the ultrasonographic examination. En block ovariohysterectomy was performed. Three live and mature foetuses were obtained from the uterus; two of them were female foetuses and had no anatomical problem but the third one exhibiting multiple malformations was a male and diagnosed as 'schistosoma reflexum' (SR). The vertebral column deviated markedly to the right (scoliosis) at thoracolumbar region, and the middle lumbar and the sacral vertebrae were directed dorsocranially (lordosis). The entire small intestine, a part of large intestine, stomach, spleen and the right kidney were displayed out of the body, and it seemed that the listed internal organs were protruded from an abdominal cleft associated with the allantoic membrane. Liver, lungs and heart were hypoplastic. The large intestine was seen to have blind end (atresia recti), but anus was normal. Cerebrum and cerebellum were noticed as normal in sizes. Chromosome preparations from lymphocyte cultures of the foetus showed chromosomal aberrations including chromatid and chromosome breaks, exchange figures, non-homologous pairing, whereas no abnormalities were detected in the chromosome preparations from mother's cultures. This is probably the first case of SR in a cat, which was examined in detail from clinical, pathological, radiological and chromosomal angles.

The importance of circulating levels of salusin-α, salusin-ß, and heregulin-ß1 in atherosclerotic coronary arterial disease.

OBJECTIVE: The relationship between the severity of atherosclerotic coronary artery disease (CAD) and circulating levels of salusin-α, salusin-ß and heregulin-ß1 has been investigated. In addition, the relationship with these peptides and high sensitive C-reactive protein (hsCRP) has been investigated. METHODS: The study was conducted on 55 volunteers who had normal coronary angiography (CAG) as the control group, 35 volunteers with the degree of coronary artery stenosis below 50% in CA as the non-critical stenosis group, 37 volunteers with narrowing of one coronary artery above 50% as single vessel group and 41 volunteers with narrowing of more than one coronary artery above 50% as multi-vessel group. One hundred and thirteen volunteers have been included to CAD group. RESULTS: There was no statistically significant difference in serum salusin-α levels between groups. Serum salusin-ß ve hsCRP levels were significantly lower in control group compared to other groups and CAD group. There was no statistically significant difference in salusin-ß and salusin-α levels in reciprocal comparison of other groups other than heregulin-ß1 levels. Heregulin-ß1 levels were significantly lower in 'non-critical occlusion' and 'multiple artery occlusion' groups compared to control group. Heregulin-ß1 levels in 'single artery occlusion' group were significantly higher than control, 'non-critical occlusion' and 'multiple artery occlusion' groups. CONCLUSION: Salusin-α levels does not indicate any significant differences between any groups in our study however the relationship of salusin-α with salusin- ß and heregulin-ß1 levels drives to cogitate that these peptides can be used as biomarkers and therapeutic approaches in CAD. We think that these peptides will be used in laboratories routinely in future in addition to hsCRP for CAD.

Hypertension and hemostatic/fibrinolytic balance disorders.

BACKGROUND: Hypertension is one of the principal risk factors for cardiovascular disease. We aimed to evaluate the impact of hypertension on fibrinolytic balance and endothelial function by measuring plasma levels of plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator antigen (tPA), tPA/PAI-1 complex and fibrinogen. METHODS: Patients enrolled into the study were divided into four groups: 22 essential hypertensive (EH), 22 white coat hypertensive (WCH), 22 renovascular hypertensive (RH) and 22 normotensive control subjects. Plasma PAI-1, tPA, tPA/PAI-1 complex levels were measured by enzyme linked immunosorbent assays. RESULTS: There was no difference in the systolic and diastolic blood pressure measurements of the EH and RH groups. The four groups were comparable for age, gender, smoking habits and BMI. Patients with EH, RH and WCH had increased plasma levels of PAI-1, tPA, tPA/PAI-1 complex and fibrinogen compared with controls. No fibrinolytic parameter was associated with blood pressure in hypretensive subjects. CONCLUSION: This prospective study showed that fibrinolytic markers such as PAI-1, tPA, tPA/PAI-1 complex are independently associated with the development of hypertension. This supports the hypothesis that disturbances in fibrinolysis precede a cardiovascular event. Therefore, hypertension may be associated with impaired fibrinolysis.

Is there a relationship between mastoid pneumatisation and facial canal dimensions?

OBJECTIVE: To evaluate mastoid pneumatisation and facial canal dimensions. METHOD: In this retrospective study, 169 multidetector computed tomography scans of temporal bone were reviewed. Facial canal dimensions were evaluated at the labyrinthine, tympanic and mastoid segments using axial and coronal multidetector computed tomography scans of temporal bone. Mastoid pneumatisation and facial canal dehiscence were evaluated. Facial canal dehiscence was measured if it was found to be present. RESULTS: This study showed that facial canal dimensions decreased in pneumatised mastoids. Facial canal dimensions in females were smaller than in males. Facial canal dehiscence was detected in 5.9 per cent and 6.5 per cent of the patients on the right and left sides, respectively. No correlations were found between facial canal dehiscence and mastoid pneumatisation. The length of dehiscence was 1.92 ± 0.44 mm (range, 0.86-2.51 mm) on the left side. In older subjects, left facial canal dehiscence was detected more, and the length of the dehiscence increased. CONCLUSION: This study concluded that during surgery, facial canal dehiscence should be kept in mind in order to avoid complications.

Expression of CYP and GST in human normal and colon tumor tissues.

We investigated the immunohistochemical staining characteristics of cytochrome P450 1A1 (CYP1A1), CYPB1, CYP2E1, and glutathione S-transferase P1 (GSTP1), GSTT1, GSTO1, GSTK1 in colon tumor and surrounding normal colon tissues. Tissues were obtained from 47 patients with colon adenocarcinoma and the staining intensity of tumor and control tissues was compared. CYP1A1, CYP1B1, CYP2E1, GSTP1, GSTT1, GSTO1 and GSTK1 expressions in colon cancer cells were significantly greater than those in normal colon epithelial cells. No significant relation was found between the isoenzyme expressions and age, gender, smoking status, tumor grade and tumor stage. The higher expressions of CYP1A1, CYP1B1, CYP2E1, GSTP1, GSTO1, GSTT1 and GSTK1 in tumor than in normal colon tissues may be important for colon cancer progression and development.

Immunocharacterization of matrix metalloproteinase-2 and matrix metalloproteinase-9 in canine transmissible venereal tumors.

Matrix metalloproteases (MMPs) are endogenous proteases that are responsible for degradation of extracellular matrix (ECM) proteins and cell surface antigens. The breakdown of ECM participates in the local invasion and distant metastases of malignant tumors. Canine transmissible venereal tumor (CTVT) is a naturally occurring contagious round cell neoplasm of dogs that affects mainly the external genitalia of both sexes. CTVT generally is a locally invasive tumor, but distant metastases also are common in puppies and immunocompromised dogs. We investigated the immune expressions and activities of MMP-2 and MMP-9 in CTVT. The presence of these enzymes in tumor cells and tissue homogenates was demonstrated by immunohistochemistry and western blotting. We used gelatin substrate zymography to evaluate the activities of MMP-2 and MMP-9 enzymes in tumor homogenates. We found that tumor cells expressed both MMP-2 and MMP-9. Electrophoretic bands corresponding to MMP-9 and MMP-2 were identified in immunoblots and clear bands that corresponded to the active forms of MMP-2 and MMP-9 also were detected in gelatin zymograms. Our study is the first detailed documentation of MMPs in CTVT.

Comparing the type and severity of inflammatory bowel disease in relation to IgG4 immunohistochemical staining.

BACKGROUD AND STUDY AIM: The role of immunoglobulin (Ig) G4 in the etiopathogenesis of inflammatory bowel disease (IBD) and its association with endoscopic and pathological activity are not yet completely understood. The purpose of this study was to determine the possible relationship between IgG4 status and IBD. PATIENTS AND METHODS: Endoscopic colon biopsies of 55 patients with ulcerative colitis (UC) and of 17 patients with Crohn's disease (CD) were examined. Numbers of IgG4-positive plasma cells stained immunohistochemically were counted in a minimum of 5 high power fields (HPFs) for each specimen. The presence of > 10 cells/HPF IgG4-positive PCs was considered positive. RESULTS: he prevalence of IgG4-positive plasma cells in the lamina propria of the colonic mucosa was significantly higher in patients with UC than in those with CD (p :0.01). Additionally, the prevalence of IgG4-positive plasma cells increased in line with endoscopic and pathological activity in UC patients. Conversely, we determined no significant correlation between IgG4 positivity and pathological activity in the CD group. IgG4-positive UC patients also exhibited findings of more severe disease compared to IgG4-negative UC patients. CONCLUSION: Immunohistochemical IgG4 staining may predict disease severity in UC and may be a useful marker for distinguishing between UC and CD.

Comparison of automatical thoughts among generalized anxiety disorder, major depressive disorder and generalized social phobia patients.

OBJECTIVE: Automatic thoughts are measurable cognitive markers of the psychopathology and coping styles of individuals. This study measured and compared the automatic thoughts of patients with generalized anxiety disorder (GAD), major depressive disorder (MDD), and generalized social phobia (GSP). PATIENTS AND METHODS: Fifty-two patients with GAD, 53 with MDD, and 50 with GSP and 52 healthy controls completed the validated Automatic Thoughts Questionnaire (ATQ) and a structured psychiatric interview. Patients with GAD, MDD, and GSP also completed the validated Generalized Anxiety Disorder-7 questionnaire, the Beck Depression Inventory (BDI), and the Liebowitz Social Anxiety Scale (LSAS) to determine the severity of their illnesses. All scales were completed before treatment and after diagnosis. The ATQ scores of all pairs of groups were compared. RESULTS: The ATQ scores of the GAD, MDD, and GSP groups were significantly higher than were those of the control group. We also found significant correlations among scores on the GAD-7, BDI, and LSAS. The mean age of patients with GSP was lower than was that of the other groups (30.90 ± 8.35). CONCLUSIONS: The significantly higher ATQ scores of the MDD, GAD, and GSP groups, compared with the control group, underscore the common cognitive psychopathology characterizing these three disorders. This finding confirms that similar cognitive therapy approaches should be effective for these patients. This study is the first to compare GAD, MDD, and GSP from a cognitive perspective.
