Adipokines and ghrelin in gastric cancer cachexia

AIM： To investigate the roles of the adipocytokines, ghrelin and leptin in gastric cancer cachexia.
METHODS： Resistin, ghrelin, leptin, adiponectin, insulin and insulin-like growth factor （IGF-Ⅰ）, were measured in 30 healthy subjects, and 60 gastric cancer patients of which 30 suffered from cancerinduced cachexia and 30 served as a control group. The relationships between hormones, body mass index （BMI） loss ratio, age, gender, and Glasgow Prognostic Score （GPS） were investigated.
RESULTS： Cachexia patients had higher tumor stage and GPS when compared with non-cachexia patients （P 〈 0.05）. Ghrelin, resistin, leptin, adiponectin and IGF- Ⅰ, showed a significant correlation with BMI loss ratio and GPS （P 〈 0.05）. A strong correlation was seen between GPS and BMI loss （R = -0.570, P 〈 0.0001）. Multivariate analysis indicated that BMI loss was significantly independent as a predictor of ghrelin, resistin, leptin and IGF-Ⅰ （P 〈 0.05）. Existence of an important significant relationship between resistin and insulin resistance was also noted.
CONCLUSION： These results showed that serum ghrelin, leptin, adiponectin, and IGF-Ⅰ play important roles in cachexia-related gastric cancers. No relationship was found between resistin and cancer cachexia. Also, because of the correlation between these parameters and GPS, these parameters might be used as a predictor factor.     

The effect of parity on pelvic floor muscle strength and quality of life in women with urinary incontinence: a cross sectional study

[Purpose] The purpose of this study was to analyze the pelvic floor muscle (PFM) activity after vaginal birth, and the effect of parity on PFM strength and quality of life (QoL) in women with urinary incontinence. [Subjects and Methods] Patients (n=241) who gave birth vaginally and experienced urinary incontinence were divided into three groups: group 1 consisted of women having 1–3 children, group 2 consisted of women having 4–6 children, and group 3 consisted of women having more than 6 children. All patients underwent detailed examination of the PFM. The Turkish version of the self-administered Incontinence Quality of Life Instrument (I-QoL) questionnaire was used to evaluate the effects of stress urinary incontinence on participants’ QoL. [Results] Comparison of PFM strengths showed a significant intergroup difference. Group 1 showed significantly higher PFM strength scores than those of groups 2 and 3. I-QoL scores related to stress incontinence showed a significant intergroup difference. As number of deliveries increased, quality of life decreased. Comparison of PFM strengths and I-QoL scores related to stress incontinence showed a significant intergroup difference. [Conclusion] Increasing the awareness of PFM training in women will reduce potential postpartum incontinence due to a weak PFM strength; and will increase quality of life.Key words: Parity, Pelvic floor muscle strength, Urinary incontinence     

A Technique for Retrofitting a Metal Ceramic Crown to an Attachment‐Retained Removable Partial Denture: A Clinical Report

In dental applications, precision attachments have been used to retain removable partial dentures (RPDs) for several decades. Various types of extracoronal attachments are commonly used in combination with fixed partial dentures and RPDs to achieve retention and stability. Fracture of the framework, fracture of the roots or teeth, and irretrievable decrease of retention are common reasons for a failed attachment‐retained RPD. Another complication of metal ceramic crowns with precision attachment is decementation of the crowns. When fixed components of the attachment‐retained RPD fail, the traditional treatment approach requires remaking both the fixed and removable components of the attachment‐retained RPD. This technique describes retrofitting of a metal ceramic crown to a resilient attachment‐retained RPD.     

New microsatellite markers for multi-scale genetic studies on Phlebotomus ariasi Tonnoir,vector of Leishmania infantum in the Mediterranean area

The population structure of Phlebotomus ariasi, a proven vector of Leishmania infantum in the Mediterranean area, is still poorly understood. Previously, only two microsatellite loci had been developed to study the population genetics of this species. Herein we use these loci and determined fourteen novel microsatellite loci, useful for the characterization of P. ariasi populations. These loci were tested on three populations of P. ariasi, two from France and one from Portugal. In addition, the usefulness of these markers was also evaluated on seven other sandfly species.     

Obstructive sleep apnea syndrome and erectile dysfunction: does long term continuous positive airway pressure therapy improve erections?

ObjectivesThe aim of this age-matched, controlled, prospective clinical study was to investigate frequency and degree of erectile dysfunction (ED) in patients with obstructive sleep apnea syndrome (OSAS) and to evaluate the results of only continuous positive airway pressure (CPAP) therapy on ED in patients with OSAS.ResultsWhen compared to the control group, a decrease in IIEF-5 scores was found in patients with OSAS. However, this decrease was not statistically significant. After 3 months of CPAP usage in patients with mild to moderate and severe degree OSAS, improvement in IIEF-5 scores was statistically significant. Mean value of IIEF-5 score was 16.63±5.91 before CPAP and were improved up to 20.92±6.79 (P=0.001).ConclusionIt is not certainly possible to say that OSAS is clearly associated with ED. However, after 3 months of regular CPAP usage, ED complaints in patients with OSAS might improve positively. Trials with larger series may give more conclusive data.     

Assessments of the associations of thrombus localization with accompanying disorders,risk factors,D-dimer levels,and the red cell distribution width in pulmonary embolism

OBJECTIVE:

Pulmonary embolisms occur as a wide spectrum ranging from clinically asymptomatic thrombi to massive thrombi that lead to cardiogenic shock. The purpose of this study was to determine the associations of thrombus localization with risk factors, accompanying disorders, D-dimer levels and the red blood cell distribution width in patients with pulmonary embolism.

MATERIAL AND METHODS:

In 148 patients diagnosed with pulmonary embolism, the presence and anatomical localization of the thrombus were assessed via computed tomographic pulmonary angiography. The accompanying disorders, risk factors, serum D-dimer levels, and red blood cell distribution width of the patients were retrospectively evaluated. ClinicalTrials.gov: NCT02388841.

RESULTS:

The mean age of the patients was 54±16.0 years, and 48 patients were ≥65 years of age. The most frequent accompanying disorders were chronic obstructive pulmonary disease (22%) and malignancy (10.1%), and the most frequent risk factors were recent operation (14.1%) and immobilization (18.2%). Thrombi were most frequently observed in the right pulmonary artery (37.8%). In 31% of the patients, the thrombus was localized to the main pulmonary arteries. Immobile patients exhibited a higher proportion of thrombi in the main pulmonary arteries than mobile patients. The mean D-dimer level and the mean red blood cell distribution width in the patients with thrombi in the main pulmonary arteries were higher than those in the patients with thrombi in more distal pulmonary arterial branches.

CONCLUSION:

Significant associations of proximally localized thrombi with immobilization, the D-dimer levels, and the red blood cell distribution width were observed.     

Effects of intra-abdominal pressure on adrenal gland function and morphology in rats

Intra-abdominal hypertension and abdominal compartment syndrome (IAH/ACS) are life-threatening conditions and caused by several clinical status. Although there is insufficient data regarding its effects on adrenal glands. This study aimed to identify whether elevated intra-abdominal pressure (IAP) caused any alteration on the morphology and function of adrenal glands in a rat model. Twenty four Sprague-Dawley male rats were included in the study. Animals were allocated into 4 groups. IAP was elevated to 15 mmHg for one hour and four hours in group 2 and 4. Group 1 and 3 were sham groups. Blood samples were taken for the assessment of plasma adrenaline, noradrenaline, and corticosterone levels and adrenalectomies were performed to evaluate apoptosis. Blood adrenaline, noradrenaline and corticosterone levels were significantly higher in the study groups compared with the sham groups. However, there were no significant changes in apoptotic index scores in the study groups as compared to sham groups. These results support that increased IAH leads to discharge of catecholamine and corticosterone from the adrenal glands. Failure to demonstrate similar changes in apoptotic index score may be concluded as apoptosis is not a leading pathway for impairment of adrenal glands during IAH period.
