Exploring Regional Disparities in Heart Failure Epidemiology and Outcomes: A Comprehensive Study Across Geographical Regions in Türkiye.

Background: Heart failure (HF) is a common condition that affects 1-3% of the general population. Its prevalence exhibits notable international and intranational disparities, partly explained by socioeconomic status, religion, ethnic diversity, and geographic factors. A comprehensive understanding of the epidemiological symptoms of HF in different regions of Türkiye has yet to be revealed. Aims: To examine epidemiological data from 2016 to 2022, focusing on crucial patient characteristics and geographical regions, to determine the incidence and prevalence of HF in Türkiye across seven diverse geographical regions. Study Design: A nationwide population-based retrospective cohort study. Methods: The comprehensive National Electronic Database of the Turkish Ministry of Health was used in this study to obtain data that covers the whole Turkish population from January 1, 2016, to December 31, 2022. The International Classification of Diseases-10 (ICD-10) codes were used to identify adults with HF (n = 2,701,099) and associated comorbidities. Türkiye is divided into seven geographically distinct regions. Epidemiological characteristics and survival data of these regions were analyzed separately. All-cause mortality was set as the primary outcome. Results: In , the total estimated prevalence of adult patients with HF is 2.939%, ranging from 2.442% in Southeastern Anatolia to 4.382% in the Black Sea Region. Except for the Eastern Anatolia Region, the three most often reported comorbidities were hypertension, dyslipidemia, and anxiety disorders. The rates of prescribing guideline-directed medical therapy (GDMT) for HF and other medications varied significantly. GDMT prescription rates were lowest in the Eastern Anatolia Region (82.6% for beta-blockers, 48.7% for RASi, 31.8% for mineralocorticoid receptor antagonists, and 9.4% for SGLT2i). The Mediterranean and Aegean regions had the highest median N-terminal brain natriuretic peptide (NT-proBNP) levels of 1,990,0 pg/ml (518.0-6,636,0) and 1,441,0 pg/ml (363.0-5,000,0), respectively. From 2016 to 2022, 915,897 (33.9%) of 2,701,099 patients died. The Eastern Anatolia Region had the lowest all-cause mortality rate of 26.5%, whereas the Black Sea Region had the highest all-cause mortality rate of 35.3%. Conclusion: Our real-world analysis revealed geographic disparities in HF characteristics, such as decreased mortality in socioeconomically challenged regions. Higher stress susceptibility in developed regions may increase the likelihood of adverse outcomes.

Processed meat products and snacks consumption in ADHD: A case-control study.

OBJECTIVE: Attention-deficit hyperactivity disorder (ADHD) has been linked to "unhealthy" food consumption, but the studies in this area are insufficient. The aim of this study is to investigate the relationship between ADHD/related symptoms and processed meat products and snack consumption. METHODS: This study was conducted on 390 children aged between 6 and 17 with 169 ADHD (38 Girls, 131 Boys) and 221 healthy controls (93 Girls, 128 Boys). Food consumption was evaluated by a modified food frequency questionnaire, including 18 food containing processed meat products and snacks. ADHD symptoms were evaluated by the teacher and parent Turgay DSM-IV-Based Child and Adolescent Disruptive Behavioral Disorders Screening and Rating Scale (T-DSM-IV-Scale) and Conners' Rating Scale (CPRS, CTRS). RESULTS: Children with ADHD consumed more processed meat products, milk-based desserts, and chocolate-sweets than controls (p<0.05). A positive correlation was observed between the ADHD symptom scores and the consumption amount of all snacks, the amount of chocolate-sweets consumption, the frequency of consumption of sujuk, chocolate, jelly beans, sweets, cakes, and chocolate spread (p<0.05). CONCLUSION: Children with ADHD consume more foods rich in saturated fat and sugar than their healthy peers. Processed food consumption of children with ADHD may be associated with ADHD symptoms.

Turkish Version of Structured Interview of Psychosis-Risk Syndromes (SIPS) and Proposal of a Brief Version of SIPS as a Pretest Risk Enrichment.

Introduction: The Structured Interview of Psychosis Risk Syndromes (SIPS) was created to identify patients with Clinical High Risk for psychosis (CHR). This study aimed i) to translate and validate the Scale of Prodromal Syndromes (SOPS) in Turkish adolescents, ii) to explore the factor structure of the SIPS/SOPS in the adolescent population, especially focusing on those under the age of 15, iii) to generate a brief version of SIPS (SIPS-B). Methods: A total of 150 adolescents aged between 12 and 18 years, were consecutively interviewed using SIPS/SOPS. Patients with psychotic syndrome (n=20), psychosis risk syndrome (PRS) (n=59), and clinical controls (CC) (n=71) were included in the study. Results: Principal component analysis (PCA) yielded three latent factors, explaining 62.7% of the total variance in the whole clinical sample, including positive symptom factor, disorganized symptom factor, and negative symptom factor. The area under curve calculated in ROC analyses involving PRS and CC supported the four-item form of the SIPS-B (optimal cut-off=12.5, sensitivity=87%, specificity=80%). Conclusion: Our study results support the notion that the Turkish translation of SIPS/SOPS meets the reliability and validity criteria in Turkish adolescents. The SIPS-B could aid clinicians in their routine clinical practice to expedite referral procedures.

The Comparison of the Right and Left Sigmoid Sinus Cross-Sectional Areas in Fetal Period and the Factors Affecting the Venous Dominance.

OBJECTIVES: Skull base is an important and a challenging area for surgeons. Success in skull base surgery depends on various factors such as pre-operative evaluation, appropriate surgical technique, anesthesia duration, intraoperative neuromonitorization and wound care. MATERIALS AND METHODS: This study was performed in the Anatomy dissection laboratory of M.U. Medical Faculty (Ethical committee approval number 2010-103). Twelve fetuses between 17-33 gestational weeks fixed with formaldehyde were enrolled to the study. RESULTS: This study was planned to investigate the cross sectional areas of the sigmoid sinus in three levels to compare the right-left sides and the probable relationship among the levels in fetuses to further delineate the developmental factors on jugular foramen asymmetry. The cross-sectional measurements of sigmoid sinus lumen were done on 3 levels which are described as A1 level; sinodural angle, A2 level; the midpoint between the sinodural angle and endocranial orifice and A3 level as the entrance (endo-cranial orifice) of the jugular foramen. There is a strong positive correlation between left (L) A1 and L A2 and also the same for L A1 and right (R) A2. These strong and positive correlations are all valid between L A2-L A3, L A2-R A2, L A2-R A3, L A3-R A3, R A1-R A2. CONCLUSION: Multicenter studies would be beneficial to investigate the topic with greater number of fetuses also on the different regions for genetic differences.

Standard triple therapy in Helicobacter pylori eradication in Turkey: Systematic evaluation and meta-analysis of 10-year studies.

BACKGROUND/AIMS: This study aims at evaluating the mean eradication rate by a systematic compilation of the studies which involved the standard triple therapy (STT) in first-line Helicobacter pylori (Hp) eradication in Turkey over a period of 10 years between 2004 and 2013 using the meta-analysis method. MATERIALS AND METHODS: The systematic compilation and meta-analysis were carried out according to the PRISMA standards defined in the Cochrane handbook. The results of full-text studies published in national and international journals in English and Turkish languages on Turkish population in a period of 10 years, from 2004 to 2013, are included in this study. The studies include open-label trials, controlled trials, treatment arms, and case series that included a triple therapy regimen consisting of standard doses of a proton pump inhibitor (PPI; omeprazole 20 mg BID, lansoprazole 30 mg BID, pantoprazole 40 mg BID, esomeprazole 40 mg BID, or rabeprazole 20 mg BID) along with clarithromycin 500 mg BID and amoxicillin 1 g BID for 7-14 days. They were scanned electronically via the search engines Google Scholar, PubMed, and the Turkish Medicine Index using specific keywords. The related keywords used were Turkey, Helicobacter pylori, infection, standard triple treatment, first-line therapy, eradication, omeprazole, lansoprazole, pantoprazole, rabeprazole, esomeprazole, clarithromycin, and amoxicillin. Studies carried out with adults were included in the evaluation. The publication year of the studies and the included number of patients, their age, gender, treatment duration (7, 10, and 14 days), and PPIs used were evaluated by two separate gastroenterologists and biostatisticians. Studies that used at least one reliable method (histology, urea breath test (UBT), or Helicobacter pylori stool antigen (HpSA) test) four weeks after completing the treatment for the control of Hp eradication were included. Only naive patients were accepted, and patients who had previously received eradication treatment were excluded. The effectiveness of the Hp eradication was analyzed using an intention-to-treat (ITT) or per-protocol (PP) analysis. RESULTS: The STT regime of 45 studies complying with the inclusion criteria was evaluated. A total of 3715 patients were included in the study. Of the 3010 patients whose gender information was available, 55% were women and 45% were men; the weighted age average given explicitly in the studies was 42.14±0.67. The treatment lasted for 14 days in 42 studies, for 7 days in six studies, and for 10 days in 1 study. The eradication rates evaluated according to the ITT and PP analyses were 60% (95% CI: 56%-63%) and 57% (95% CI: 51%-62%), respectively. The rates for 7 days of treatment were 57% (95% CI: 46%-68%) and 60% (95% CI: 51%-67%) and for 14 days of treatment were 60% (95% CI: 56%-63%) and 56% (95% CI: 50%-62%), respectively. The ITT eradication rate of the only 10-day study was 78% (95% CI: 66%-86%). In the meta-regression analysis, the treatment duration, PPI, age, and gender ratio (women/men) used for the ITT analysis had no effect. The gender ratio and age were not considered in this analysis because they were not clearly stated in studies using the PP analysis. The duration of treatment and the PPI used had no effect. CONCLUSION: A systematic meta-analysis of studies conducted during the period 2004-2013 in Turkey revealed that the rate of first-line Hp eradication using STT was unacceptably low, and the duration of treatment and PPI used made no difference.

Histopathologic evaluation of Ecballium elaterium applied to nasal mucosa in a rat rhinosinusitis model.

This study aimed to evaluate the antimicrobial effects of the medicinal plant Ecballium elaterium, which is topically applied as a traditional medicine for the treatment of rhinosinusitis. Pure and extract forms of E elaterium were applied to the nasal cavity of rats for the treatment of Streptococcus-pneumoniae -induced rhinosinusitis. The nasal mucosa, soft palate, and trachea of the rats were harvested in the first hour, third day, and third week for histopathologic evaluation. This experiment revealed the anti-inflammatory effects of E elaterium and showed that it reduced fibrosis. The anti-inflammatory effect of all forms of E elaterium was found to reach its maximum level on the third day, decreasing by the third week. We also observed that the pure form of E elaterium caused severe epithelium loss in the first hour after application. The mechanism of the anti-inflammatory effect of different levels of extract forms needs to be further analyzed with different doses and duration of treatment.

The Measurement of Various Anatomical Structures and Assessment of Morphometric Development of Fetal Skull Base.

BACKGROUND: As the skull base has a complex anatomy, we underline the importance of anomalies for side asymmetry. It is useful to investigate relationship between anatomical structures for the surgical procedure orientations. Dural adherence, enlarged superior petrosal sinus, influence of neural crest cells, and cranial base ossification are among the factors in morphometric growth on skull base. MATERIAL AND METHODS: Twenty-five fetuses of an estimated gestational age ranging from 17 to 34 weeks were studied in the Anatomy Laboratory of Mersin University Medical Faculty. Craniotomy was made to each fetus and brain hemispheres were dissected. We put plates, passing from the external points of lateral and anterior-posterior borders of fetus heads that are perpendicular to each other. An analytical calculation was formulated for the angle of foraminae to the root of zygoma by using different formulations depending on their posterior or anterior location to the root of zygoma. Statistical method was based on correlation analysis, simple regression, independent 2 group t tests, SPSS20.0, and MedCalc 11.5 (MedicReS, New York, NY). RESULTS: Neither side dominance for the jugular foramen, nor the differences of foramen rotundum, spinosum, and ovale to anterior skull wall, root of zygoma, and to midline were found to be significant. CONCLUSION: There is a debate on asymmetry of foramina of the skull base. No certain consensus about the initiation time and the causes of asymmetry in the past was documented. Studies are to be encouraged to further enlighten pre-postnatal factors affecting the fetal skull base morphometrism.

Effects of Hypericum perforatum on an Experimentally Induced Diabetic Wound in a Rat Model.

OBJECTIVE: The aim of this study was to investigate the probable effects of Hypericum perforatum (HP) on wound healing in diabetic rats. MATERIALS AND METHODS: Thirty-five male Wistar rats were divided evenly into 5 groups. Diabetes formation was induced by intraperitoneal streptozotocin (60 mg/kg) administration for groups 1 (HP extract in olive oil), 2 (HP extract in ethanol), 3 (povidone-iodine application), and 4 (diabetic rats without any applied medication); group 5 was the control. Dorsal dermoepidermal incision was performed on each rat after 48 hours. The aforementioned solutions were applied only to groups 1, 2, and 3; groups 4 and 5 did not receive solution applications. At the end of the 7-day period, the cutaneous tissue was resected from the center of the incised and sutured region and divided into 3 pieces for biomechanical, biochemical, and histopathological assessments. RESULTS: Ultimate stress and toughness significantly decreased in groups 3, 4, and 5 compared to group 1. There was a significant difference between groups 2 and 3 for the same parameters (P < .05). Compared with group 4, tissue malondialdehyde levels were found to be lower in the HP groups (P < .05). Histopathological evaluation revealed the fibroblast count was reduced considerably in the HP-applied rats compared with other groups (P < .05). CONCLUSION: Application of HP may be recommended as effective on wound healing in diabetic rats, but further investigation is needed to adapt the findings for clinical use.

Serum RDW and MPV in Ankylosing Spondylitis: Can they show the disease activity?

OBJECTIVE: To determine RDW and MPV levels in Ankylosing Spondylitis (AS) and to investigate their relations with disease activity. MATERIALS AND METHODS: 133 patients with AS (male: 80, female: 53) and age-sex matched 133 controls (male: 79, female: 54) were enrolled. Demographic data, disease activity scores, Complete Blood Count (CBC), Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) levels were recorded. RESULTS: The mean ages of patients and controls were 41.9±11.2 and 39.7±14.2 years respectively (p = 0.16). RDW (14.5±1.6% and 13.2±0.8%, p < 0.0001 respectively) and MPV (10.1±0.8fl and 9.9±0.7fl, p = 0.03, respectively) were significantly higher in patients with AS than in controls. There was a significant difference in RDW between patients with active AS (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) >4) and those with inactive AS (BASDI <4) patients (14.84±1.79fl, 14.24±1.37fl, p = 0.035 respectively). RDW was positively correlated with BASDAI (r = 0.33, P < 0.0001), ESR (r = 0.45, P < 0.0001) and CRP (r = 0.42, P < 0.0001) and PLT levels (r = 0.24, P = 0.004). While MPV was not correlated with BASDAI, it was negatively correlated with ESR (r = -0.19, P = 0.03), CPR (r = -0.26, P = 0.004) and PLT levels (r = -0.39, P = <0.0001). CONCLUSIONS: RDW and MPV were significantly higher in the patients with AS than in the controls. While RDW was correlated with BASDAI and APRs, MPV was only correlated with APRs.

Can mean platelet volume and red blood cell distribution width show disease activity in rheumatoid arthritis?

AIM: To evaluate the relationship between mean platelet volume (MPV) and red cell distribution width (RDW), and disease activity in rheumatoid arthritis (RA). PATIENTS & METHODS: Hundred RA and 100 controls were included. RESULTS: MPV and RDW were higher in RA (p < 0.0001). The cut-off levels of RDW and MPV were 14.8 and 10.4. Patients with RDW >14.8 had higher Disease Activity Score 28 (DAS28; p = 0.002) and pain score (p = 0.0007). RDW was positively correlated with DAS28 and pain. But, DAS28 and pain were not different between patients with MPV >10.4 and <10.4. CONCLUSION: MPV and RDW were significantly higher in RA. RDW and MPV were similar to erythrocyte sedimentation rate and C-reactive protein to indicate inflammatory activity. RDW was correlated with pain and DAS28, but MPV was not associated with them.

Sleep quality in patients with chronic low back pain: a cross-sectional study assesing its relations with pain, functional status and quality of life.

OBJECTIVE: The aim of this study was to investigate sleep quality in patients with chronic low back pain (CLBP) and its relationship with pain, functional status, and health-related quality of life (HRQOL). METHODS: Two hundred patients with CLBP aged 20-78 years (mean: 50.2 years) and 200 sex- and age-matched pain-free healthy controls (HCs) aged 21-73 years (mean: 49.7 years) were included in this study. After lumbar region examination, in patients, pain was evaluated with the Short Form-McGill Pain Questionnaire (SF-MPQ), functional capacity with the Functional Rating Index (FRI), and health-related quality of life with the Short Form-36 (SF-36). The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality of both groups.The sleep quality was compared between the patients and HCs. In patients with CLBP, its relations with pain, functional status and HRQOL were also investigated. RESULTS: The patients had significantly higher total scores (8.1 ± 4.3, 4.6 ± 3.4, P< 0.001, respectively) and subscale scores (P< 0.001) for PSQI compared to HCs. The groups were only similar in use of sleeping medication (P> 0.05) Among the patients, sleep quality was worse in women, in the patients with complaints more than 11 years, in the patients with low back and two leg pain (P< 0.05). Mean scores of the FRI, SF-MPQ, and visual analog scale in the patients were 8.5 ± 3.0, 16.7 ± 8.0, 6.9 ± 1.2, respectively. The PSQI total scores of patients were positively related with both SF-MPQ and FRI scores (P< 0.001). Also, there were negative relationships between the physical component summary score of the SF-36 and all subscale scores of the PSQI, without sleep duration of PSQI (P< 0.001). CONCLUSION: The sleep quality of patients with CLBP was worse compared to HCs, and there were positive relations between the sleep quality with pain and functional status. Also, the poor sleep quality had negative effect on the physical component of quality of life.

The effect of tumor necrosis factor-α inhibitor soon after hypoxia-ischemia on heart in neonatal rats.

AIMS: Perinatal hypoxic-ischemic insult has acute and long term deleterious effects on many organs including heart. Although tumor necrosis factor alpha (TNF-α) has been reported to increase soon after hypoxia, the inhibition of this mediator has not been documented. The aim of this study was to investigate the effects of a TNF-α inhibitor (etanercept) on contractility and ultrastructure of rat heart muscles exposed to hypoxia-ischemia during neonatal period. MAIN METHODS: Forty-five seven-day old rats divided into three groups were included in this study. The right carotid arteries of Saline and Etanercept groups of rats were ligated and kept in a hypoxia chamber containing 8% oxygen for 2h. Immediately after hypoxia, while Etanercept group was administered 10mg/kg etanercept, Saline group had only saline intraperitoneally. The carotid arteries of rats in Sham group were located without ligation and hypoxia. Mechanical activity of heart was recorded and tissue samples were examined by electron microscopy in the sixteenth week following the hypoxia-ischemia. KEY FINDINGS: While atrial contractile force in Etanercept group was similar to Sham group, there was significant decrease in Saline group (p<0.001). However, there was only non-significant decrease in ventricular contractility of Saline group comparing to Sham group (p>0.05). After hypoxia-ischemia, ultrastructural degenerative changes and mitochondrial damage in atriums of Etanercept group were significantly less severe than Saline group. SIGNIFICANCE: This study demonstrated that neonatal hypoxia-ischemia caused long term cardiac dysfunction and ultrastructural degenerative changes in the heart of rats. TNF-α inhibitor administration soon after hypoxia-ischemia may have heart protective effect.

Affirmative effects of iloprost on apoptosis during ischemia-reperfusion injury in kidney as a distant organ.

OBJECTIVE: Apoptosis and its regulatory mechanisms take part in renal ischemia-reperfusion (I/R) injury which can result in acute renal failure and the inhibition of the caspase is considered as a new therapeutic strategy. In this context, we investigated the antiapoptotic and cytoprotective effects of iloprost, a prostacyclin analog, in kidney as a distant organ. METHODS: Wistar albino rats were randomized into five groups (n = 12 in each) as sham, ischemia, I/R, iloprost (10 µg kg(-1)), and I/R + iloprost (10 µg kg(-1)). A 4 h reperfusion procedure was carried out after 4 h of ischemia. Caspase-8 was evaluated for death receptor-induced pathways, whereas caspase-9 was evaluated for mitochondria-dependent pathways and caspase-3 was investigated for overall apoptosis. Superoxide dismutase (SOD) enzyme activity and nitrite content as an indicator of nitric oxide (NO) production were also analyzed in kidney tissues. RESULTS: Caspases-3, -8, and -9 were all significantly elevated in both ischemia and I/R groups compared to the sham group; however, treatment with iloprost reduced caspases-3, -8, and -9. SOD enzyme activity was attenuated by iloprost when compared to ischemic rats. The different effects of NO were found which change according to the present situation in ischemia, I/R, and treatment with iloprost. CONCLUSIONS: These findings suggested that iloprost prevents apoptosis in both receptor-induced and mitochondria-dependent pathways in renal I/R injury and it may be considered as a cytoprotective agent for apoptosis. Understanding the efficiency of iloprost on the pathways for cell death may lead to an opportunity in the therapeutic approach for renal I/R injury.

Quantitative ultrasound biomicroscopy study of biometry of the lens and anterior chamber.

PURPOSE: To quantify the changes induced by cataract extraction (CE) in angle recess area (ARA), angle opening distance at 250 and 500 µm (AOD250, AOD500), and aqueous depth (AQD) in comparison with axial lens thickness (LT) and to reveal effects of LT and lens position (LP) on angle parameters and AQD using ultrasound biomicroscopy (UBM). METHODS: Thirty-five eyes of 35 patients (22 male; mean age 69.5 ± 7.8 years) with senile or presenile cataract who consecutively underwent cataract surgery were enrolled in this institutional study. We performed UBM examinations before and 1 month after surgery under a standard protocol. Axial images of the anterior segment and radial sections of the angle at 4 quadrants were obtained. Aqueous depth and LT were measured in immersion A-scan mode and we used UBM Pro 2000® software for the ARA, AOD250, and AOD500. RESULTS: Aqueous depth and angle parameters at 4 quadrants were increased significantly after CE (p<0.05). The mean LT was 4.53 ± 0.37 mm and LP was 4.96 ± 0.25 mm preoperatively. There were statistically significant correlations between LT, LP, and AQD and angle parameters preoperatively. We also determined statistically significant correlations between LT, LP, and postoperative changes in AQD and angle parameters In comparison with LT, the mean increases in AQD, ARA, AOD250, and AOD500 were 0.21, 0.014, 0.012, and 0.017 times, respectively. CONCLUSIONS: The results suggest that LT is as a significant factor as LPon the final dimensions of the anterior chamber and angle.

The association between cyclooxygenase-2 (COX-2/PTGS2) gene polymorphism and osteoarthritis.

OBJECTIVES: This study aims to investigate the relationship between the risk for the development of osteoarthritis and Cyclooxygenase-2 (COX 2) -765G>C gene polymorphism. PATIENTS AND METHODS: We included a total of 100 osteoarthritis patients (18 males, 82 females; mean age 60.4±8.4 years; range 41 to 81 years) who were treated in the Physical Therapy Clinic and 100 healthy subjects without a history of arthritis (40 males, 60 females; mean age 30.9±7.5 years; range 16 to 48 years) in our study between September 2006 and May 2008. The frequency of -765G>C gene polymorphism in the COX-2 promoter region was investigated in the osteoarthritis patients and the control group without a history of arthritis using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The data were analysed with chi-square and logistic regression analysis. RESULTS: The frequencies of -765G>C polymorphism for GG, GC and CC genotypes were found to be 54%, 35%, and 11% in the control group and 48%, 34% and 18% in the osteoarthritis group, respectively. CONCLUSION: Based on the data obtained, it can be stated that there is no significant relation between COX-2 -765G>C polymorphism and osteoarthritis disease. Furthermore, this study presents the first results of COX-2 promoter variant in Turkish patients with osteoarthritis.

The effect of pelvic organ prolapse on sexual function in a general cohort of women.

INTRODUCTION: This is a report about the effects of pelvic organ prolapse on sexual function in women. AIM: To determine the effect of pelvic organ prolapse on sexual function in women. METHODS: The study group consisted of 1,267 sexually active women. Baseline characteristics, medical and obstetric history of the patients were recorded. All women underwent vaginal examination to determine the degree of prolapse by pelvic organ prolapse quantification (POPQ) system. Of 1,267 women, 342 (27.0%) had prolapse stage ≥2. MAIN OUTCOME MEASURE(S): The Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaire short form (PISQ-12) scores of the women were recorded. RESULT(S): Women with genital prolapse had lower PISQ-12 scores than women without it. The difference resulted mainly from urinary incontinence during sexual activity, fear of incontinence and avoidance of intercourse due to prolapse. Multivariate analyses showed that genital prolapse was one of the confounding factors for sexual function. CONCLUSION(S): Pelvic floor dysfunction is a multi-faceted problem because it has both anatomical and functional aspects. Although pelvic organ prolapse had an effect on some aspects of sexuality, it has no effect on certain aspects of sexual function such as orgasm and sexual satisfaction.

[How exactly can we predict the prognosis of COPD]. / KOAH hastalarinin progresyonlarini ne ölçüde tahmin edebiliriz?

Predictive models play a pivotal role in the provision of accurate and useful probabilistic assessments of clinical outcomes in chronic diseases. This study was aimed to develop a dedicated prognostic index for quantifying progression risk in chronic obstructive pulmonary disease (COPD). Data were collected prospectively from 75 COPD patients during a three years period. A predictive model of progression risk of COPD was developed using Bayesian logistic regression analysis by Markov chain Monte Carlo method. One-year cycles were used for the disease progression in this model. Primary end points for progression were impairment in basal dyspne index (BDI) score, FEV(1) decline, and exacerbation frequency in last three years. Time-varying covariates age, smoking, body mass index (BMI), severity of disease according to GOLD, PaO2, PaCO(2), IC, RV/TLC, DLCO were used under the study. The mean age was 57.1 + or - 8.1. BDI were strongly correlated with exacerbation frequency (p= 0.001) but not with FEV(1) decline. BMI was found to be a predictor factor for impairment in BDI (p= 0.03). The following independent risk factors were significant to predict exacerbation frequency: GOLD staging (OR for GOLD I vs. II and III = 2.3 and 4.0), hypoxemia (OR for mild vs moderate and severe = 2.1 and 5.1) and hyperinflation (OR= 1.6). PaO2 (p= 0.026), IC (p= 0.02) and RV/TLC (p= 0.03) were found to be predictive factors for FEV(1) decline. The model estimated BDI, lung function and exacerbation frequency at the last time point by testing initial data of three years with 95% reliability (p< 0.001). Accordingly, this model was evaluated as confident of 95% for assessing the future status of COPD patients. Using Bayesian predictive models, it was possible to develop a risk-stratification index that accurately predicted progression of COPD. This model can provide decision-making about future in COPD patients with high reliability looking clinical data of beginning.

Comparison of bladder perceptions during cystometry in pediatric and adult patients.

OBJECTIVES: This study was designed to evaluate the reliability of bladder perception in children and compare it with that in adults. METHODS: A total of 30 children were included in the study. The average patient age was 11 years (range 7-16). In the first phase of the study, a catheter was fixed to the skin without introducing it through urethra. After the children were told that the test had begun, they were asked to report any sensations. In the second phase, although an 8F urodynamics catheter had been introduced, nothing was infused. In the third phase, regular filling cystometry was performed. The final phase of the study was performed using the same method as for the second phase. The intervals that elapsed until each sensation was perceived were recorded in seconds and were used to compare the perceptions. RESULTS: Of the 30 children, 4 were excluded because of sensation defects in the cystometric evaluation. In the first phase, none of the children reported any first sensation, first desire, normal desire, or strong desire. In the second phase, 3 of the children reported a first sensation and 2 reported a first desire. In the third phase, all 26 children reported sensations and the first sensation/normal desire percentage was 41% and the first desire/normal desire percentage was 52%. In the fourth phase, none of the children reported sensations. CONCLUSIONS: In our previous studies, we reported that an important percentage of adults perceived false sensations in the fake phases. The children had no significant perceptions in the fake phases (first, second, and fourth phases). Thus, the sensations reported by children during urodynamics studies are more reliable than those reported by adults.

The monitoring of progress in apoptosis of liver cells in bile duct-ligated rats.

BACKGROUND/AIMS: We aimed to determine the progress of lipid peroxidation and ultrastructural changes established in the rat liver after acute bile duct ligation. METHODS: Groups A1, B1, C1 and D1 were the controls of groups A2, B2, C2 and D2, which represented the 1st, 3rd, 5th and 8th days after bile duct ligation. Serum bilirubin and malondialdehyde, liver malondialdehyde and reduced glutathione levels, and inducible nitric oxide synthase expression were determined. Liver tissue was examined with light and electron microscopy. RESULTS: Serum bilirubin increased progressively. Serum and liver malondialdehyde and inducible nitric oxide synthase expression reached a peak level at day 3, reduced at the 5th day and continued at a constant rate. Reduced glutathione decreased progressively. Ductal proliferation increased progressively to a plateau at day 5. The marked electron microscopic changes were detected at day 3 (B2) and continued constantly. CONCLUSIONS: The first five days after acute bile duct ligation are the most critical.

[Effect of dynamic hyperinflation on exertional dyspnea, exercise performance and quality of life in COPD]. / KOAH'da dinamik hiperinflasyonun egzersiz dispnesi, egzersiz kapasitesi ve yasam kalitesine etkisi.

There is increasing evidence that dynamic hyperinflation (DH) have negative effects on exercise performance and quality of life in chronic obstructive pulmonary disease (COPD) patients. The aim of this study was to investigate effect of dynamic hyperinflation on exertional dyspnea, exercise performance and quality of life in patients with COPD. 72 clinically stable patients with moderate to severe COPD and 30 healthy age-matched control subjects were included in this study. Pulmonary function tests including lung volumes and maximal respiratory muscle forces, arterial blood gas analyses, evaluation of exertional dyspnea with the Borg scale, and The Saint George Respiratory Questionnaire (SGRQ, Turkish version) were performed at rest and after a 6-min walk test. We measured the change in inspiratory capacity (AlphaIC) after exercise to reflect DH. 80% of patients with COPD significantly decreased IC after exercise (DH). AlphaIC were -0.27 +/- 0.26 L in COPD and 0.8 +/- 0.17 L in controls (p= 0.001). A stepwise multiple regression analysis showed that to be a patient with COPD, Basal Dyspnea Index (BDI) and AlphaIC were the best predictors of 6 MWD (r(2)= 0.53, p< 0.001). FEV1 added an additinal 9% to the variance in 6 MWD. Exertional dyspnea (AlphaBorg) correlated with AlphaIC (r= -0.44, p= 0.0001) and BDI (r= 0.34, p= 0.02). AlphaIC significantly correlated with symptom (r= -0.36, p= 0.008), activity (r= -0.31, p= 0.03) and total scores (r= -0.30, p= 0.04) of SGRQ. Dynamic hyperinflation can often occur during exersice in patients with COPD. Extent of dynamic hyperinflation could able to explain exercise capacity limitation, exercise dyspnea, and poor quality of life in patients with COPD.
