Does the efficacy of regorafenib differ in chemotherapy refractory metastatic colorectal cancer patients who had mucinous pathology compared to those who had non-mucinous pathology?

Purpose: To investigate the importance of mucinous histopathology on the assessment of tumor response in patients with metastatic colorectal cancer (mCRC) receiving regorafenib. Materials and method: All patients diagnosed with histologically confirmed mCRC in 2 oncology centers between 2013 and 2018 were retrospectively analyzed. Among 678 patients diagnosed with mCRC, 103 patients were treated with regorafenib. Ninety-four of these patients who had used at least 2 cycles of regorafenib and evaluable for treatment response were included in the analysis. Histopathologically, 18 patients with mucinous adenocarcinoma and 76 patients with nonmucinous adenocarcinoma were compared in terms of response rate and survival durations. Results: Median follow-up duration of 6 months, median age of the patients was 61 (34-77) years. While 19.1% of the patients had mucinous histology, 80.9% had nonmucinous histology. The overall response rate was significantly lower in the mucinous subgroup than the nonmucinous subgroup (5.6% vs 43.4%, respectively, P = 0.003). Similarly, both progression-free survival (3.0 vs 4.0 months, respectively, P = 0.011) and overall survival duration were shorter in the mucinous subgroup (3.0 vs 7.0 months, P = 0.016, respectively) compared with the nonmucinous subgroup. Conclusion: The histological subgroup may predict tumor response in mCRC patients receiving regorafenib. Its efficacy on nonmucinous histology had significantly more favorable than mucinous subtype.     

Relationship Between Functional Exercise Capacity and Lung Functions in Obese Chidren

Objective:Cardiovascular, respiratory and musculoskeletal system disorders which may affect the functional exercise capacity are common in obese patients. We aimed to investigate the functional exercise capacity and its relationship with functional pulmonary capacity in obese children.Methods:A total of 74 obese and 36 healthy children as a control group were enrolled in the study. Pulmonary functions and functional exercise capacity were measured by spirometry and six-minute walk test (6 MWT), respectively.Results:The distances covered during the 6 MWT in obese and control groups were 570.9±67.5 and 607.8±72.5 meters, respectively (p=0.010). In spirometric pulmonary function tests (PFTs), forced expiratory volume in 1 sec (FEV1) and forced mid-expiratory flows (25-75) were lower in the obese group (p=0.048 and p=0.047, respectively), whereas forced vital capacity (FVC), the FEV1/FVC ratio and peak expiratory flow were not statistically different between the obese and control groups. Multiple regression analysis revealed that among all parameters of anthropometric measures and PFTs, only body mass index standard deviation score (BMI-SDS) was the independent factor influencing 6 MWT.Conclusion:Functional exercise and lung capacities of obese children were diminished as compared to those of non-obese children. The most important factor influencing functional exercise capacity was BMI-SDS.     

Influence of polymerisation method and type of fibre on fracture strength of endodontically treated teeth

The aim of this study was to investigate (i) the effect of direct or indirect polymerisation of adhesive‐impregnated ribbon fibre under 4‐mm bulk‐filled composites on fracture strength; (ii) to compare polyethylene ribbon fibre‐reinforcement composites with short fibre‐reinforced composite; and (iii) the effectiveness of polyethylene ribbon fibre according to the restorative materials used (low‐viscous bulk‐fill composite, high‐viscous flowable composite or conventional paste composite). Seventy molars were divided into seven groups; (groups 1–2) Ribbond‐reinforced Surefil‐SDR; (group 3) Ribbond‐reinforced G Aenial Flo; (group 4) Ribbond‐reinforced G Aenial Posterior; (group 5) short fibre‐reinforced composite everX Posterior; (group 6) unfilled cavity; (group 7) intact teeth. Ribbond was adopted to cavity walls by impregnating an adhesive and using a flowable composite. In group 1, adhesive‐impregnated Ribbond was polymerised directly using a light‐curing‐unit, and indirectly in group 2 under 4‐mm bulk‐filled composite. Direct or indirect polymerisation of adhesive impregnated ribbon fibre under 4‐mm bulk‐filled composite did not change the fracture strength results. Polyethylene ribbon fibre‐reinforced groups (groups 1–4) and short fibre‐reinforced composite group (group 5) displayed similar results. Polyethylene ribbon fibre can be used safely under 4‐mm bulk‐filled composites. Ribbond‐reinforced low‐viscous bulk‐fill, high‐viscous flowable, and conventional paste composite exhibited similar fracture strength results.     

Examining prevalence of urinary incontinence and risk factors in women in third postpartum month

Are pregnancy and birth‐related parameters important risk factors in the development of urinary incontinence (UI)? The aim of this study is to examine the prevalence of UI and associated risk factors in Turkish women in the third postpartum month. Incontinence after childbirth is a common problem. A cross‐sectional study that included 370 women in third postpartum month in Çanakkale is presented in this paper. Wagner's quality of life scale questionnaire exploring the risk factors for UI was used as the principle data collection tool. All women gave consent prior to inclusion in the study. Chi‐square, t test, Mann‐Whitney U test and Binary logistic regression were used for comparison. The prevalence of self‐reported postpartum UI was 35.9%. In this study; age, educational level, parity, number of normal birth, nocturia and constipation were determined to be the associated risk factors for postpartum UI in univariate analysis. When examining these risk factors by using logistic regression, it was found that the number of birth being 2 increased UI 2.7 times (P = 0.002, 95% CI:1.434‐5.324), the number of birth being 3 or more increased UI 20.3 times (P = 0.001, 95% CI:7.130‐58.332) and nocturia being 3 times and more increased UI 2.6 times (P = 0.041, 95% CI:1.042‐6.790). Pregnancy and birth‐related parameters are important risk factors in development of UI. It would be useful to increase the awareness in women in pregnancy and the postpartum period, by providing health training and consultancy services about UI protection and the reduction of risk factors.     

Is GDF-15 level associated with gestational diabetes mellitus and adverse perinatal outcomes?

ObjectiveGrowth differentiation factor-15 (GDF-15), the new member of transforming growth factor (TGF)-beta family, is released as a response of oxidative stress, inflammation and tissue injury. We aimed to determine GDF-15 levels in patients with Gestational Diabetes Mellitus (GDM) and the relation between GDF-15 and adverse perinatal outcomes.Materials and methods:Forty pregnant women with GDM (receiving diet and insulin therapy) and forty healthy pregnant women as control group participated in this current study. GDF- 15 levels were analyzed by enzyme-linked immunosorbent assess kit.ResultsThe median serum GDF-15 level was measured higher in patients with GDM, and it was statistically meaningful (p: 0.000). Logistic regression analysis indicated that with the increase of GDF-15 level, the risk of GDM diseases increases as well. (P: 0.001, OR = 1.009; 95% CI = 1.003–1.014). There were no differences between GDF-15 levels and perinatal outcomes.ConclusionWe concluded that higher GDF-15 levels are related to GDM in the third trimester. The optimal GDF-15 cut-off value was measured as 326 pg/ml for the diagnosis of GDM with 70% sensitivity and 60% specificity in our study. Further studies are needed to show the significance of GDF-15 as a biomarker for the disease.     

Traumatic Effects of the COVID-19 Outbreak in Middle School Students and Caregivers

Objective To investigate the traumatic effects of the COVID-19 pandemic on middle-school students and their parents. Methods This epidemiological cross-sectional study was conducted with middle-school students in Denizli. A questionnaire consisting of the IES-R, CRIES-13 and a sociodemographic data form was delivered online. A total of 1059 participants who fully completed the questionnaire were included for analysis. Results The IES-R total and subdimension scores and the CRIES-13 scores were found to be significantly higher in families with an income level of ≤2,500 TL. The CRIES-13 scores of children were found to be significantly higher in divorced families. No statistically significant difference was determined between the IES-R total and subdimension scores of the parents who were healthcare workers and the CRIES-13 scale scores of their children. Conclusion A statistically significant, positive, moderate relationship was found between the IES-R scale total and subdimension scores of parents and the CRIES-13 scale scores of children. A low socioeconomic level was seen to increase the prevalence of anxiety in adults and adolescents. The children of divorced families were found to be at higher risk of PTSD. Successful management of mental health symptoms in parents will reflect positively on the mental health status of their children.     

Pulsed dye laser treatment of genital warts

BACKGROUND AND OBJECTIVES: Genital warts represent benign epithelial proliferations induced by human papillomavirus. The goal of treatment is the clearance of visible warts. Different regimens are available. Flashlamp-pumped pulsed dye laser (FPDL) represents one of many treatment options for the management of viral warts (verrucae vulgares), its effectiveness being comparable with that of conventional therapies. We evaluated the effectivity of FPDL light for the treatment of genital warts. STUDY DESIGN/MATERIALS AND METHODS: A prospective study was performed to examine the efficacy of FPDL in untreated genital warts in which 22 patients were included. RESULTS: All patients showed complete remission after 1.59 (1-5) laser sessions and no scarring was observed. CONCLUSIONS: This study demonstrate that FPDL is a simple and safe, cost and time saving alternative treatment option for genital warts and should be listed in genital warts treatment guidelines.
