Adipokines and Systemic Inflammation in Weight-Losing Lung Cancer Patients

Background  

Cancer cachexia is a devastating condition leading to loss of function and independence, decreased performance status, decreased quality of life, and poor prognosis. Adipokines play a role in a wide variety of physiological or pathological processes, including immunity and inflammation, in addition to having significant effects on metabolism and lipogenesis. The objective of the present study was to investigate the relationship of adipokines and systemic inflammation in weight-losing advanced-stage non-small-cell lung cancer (NSCLC) patients.     

Effects of different surface treatments on shear bond strength in two different ceramic systems

The purpose of this study was to evaluate the influence of different surface treatments (sandblasting, acid etching, and laser irradiation) on the shear bond strength of lithium disilicate-based core (IPS Empress 2) and feldspathic ceramics (VITA VM 9). One hundred ceramic discs were divided into two groups of 50 discs each for two ceramic systems: IPS Empress 2 (group I) and VITA VM 9 (group II). Each of the two groups was further divided into five surface treatment groups (ten each) as follows: group SB, sandblasting with alumina particles (50 μm); group HF, 5 % hydrofluoric acid etching; group L, Er:YAG laser irradiation (distance, 1 mm; 500 mJ; 20 Hz; 10 W; manually, noncontact R14 handpiece); group SB–L, sandblasting + Er:YAG laser; and group HF–L, 5 % hydrofluoric acid + Er:YAG laser. Luting cement (Panavia 2.0) was bonded to the ceramic specimens using Teflon tubes. After 24 h of water storage, a shear bond strength test was performed using a universal testing machine at a crosshead speed of 0.5 mm/min. The data were analyzed with a two-way analysis of variance (ANOVA) and Tukey's honestly significant difference tests (α?=?0.05). The two-way ANOVA indicated that the shear bond strength was significantly affected by the surface treatment methods (p?<?0.05), but there was no significant interaction between the ceramic systems. Group SB–L had the highest mean values for each ceramic system. Sandblasting, followed by Er:YAG laser irradiation, enhanced the bond strength, indicating its potential use as an alternative method. The atomic force microscopic evaluation revealed that group SB had the most distinct sharp peaks among the groups.     

Low ERCC1 expression is associated with prolonged survival in patients with bladder cancer receiving platinum-based neoadjuvant chemotherapy

PurposeExcision repair cross-complementation group 1 enzyme (ERCC1) plays a key role in the removal of platinum induced DNA adducts and cisplatin resistance. Prognostic role of ERCC1 expression in the neoadjuvant setting in bladder cancer has not been reported before. We evaluated the prognostic role of ERCC1 expression in bladder cancer receiving platinum-based neoadjuvant chemotherapy.Materials and methodsThirty-eight patients with muscle invasive bladder cancer who received neoadjuvant platinum-based chemotherapy were included. Clinical and histopathologic parameters along with immunohistochemical ERCC1 staining were examined and correlated with response rates and survival.ResultsPathologic complete response rates were similar between patients with low and high ERCC1 expression. Median disease-free survival (DFS) was 9.3 vs. 20.5 months (P = 0.186) and median overall survival (OS) was 9.3 vs. 26.7 months (P = 0.058) in patients with high ERCC1 expression compared with those with low expression, respectively. In multivariate Cox regression analysis: pathological complete response (pCR) after chemotherapy (hazard ratio (HR) 0.1, 95% CI 0.012–0.842, P = 0.034) and high ERCC1 expression (HR 3.7, 95% CI 1.2–11.2, P = 0.019) were significantly associated with DFS. Patient age (>60 vs. ≤60 years) (HR 3.4, 95% CI 1.2–9.4, P = 0.018), the presence of pCR (HR 0.11, 95% CI 0.014–0.981, P = 0.048) and high ERCC expression (HR 6.1, 95 CI 1.9–19.9, P = 0.002) were significantly associated with OS.ConclusionsOur results showed that high ERCC1 expression was independently associated with shorter disease-free and overall survival in patients with bladder cancer who received neoadjuvant platinum-based chemotherapy. ERCC1 may represent a potential predictive marker for platinum-based treatment in bladder cancer.     

Endoscopic evacuation of cerebellar hematoma in a term newborn

Intracerebellar hemorrhage is very rare in term infants and only severe cases with massive intracranial hemorrhage, posthemorrhagic hydrocephalus and clinical deterioration due to increased intracranial pressure require neurosurgical evacuation. In recent adult studies endoscopic hematoma evacuation has been shown as a rapid, effective, and safe technique. A term newborn hospitalized for meconium aspiration syndrome showed hypertonia, jitteriness and abnormal amplitude integrated electroencephalogram findings. He was diagnosed with cerebellar hematoma which caused hydrocephalus by cranial magnetic resonance imaging (MRI). The hematoma was successfully evacuated neuroendoscopically as the first case in literature to our knowledge. Neurologic, a-EEG and MRI findings resolved.     

Environmental determinants of atopic eczema phenotypes in relation to asthma and atopic sensitization

BACKGROUND: There is still uncertainty about the determinants of atopic eczema (AE). To explain the heterogeneity of the disease, different phenotypes of AE have been suggested. METHODS: The cross-sectional PARSIFAL study included 14 893 school-age children of farmers or children attending Steiner schools and their respective reference groups. A detailed questionnaire was completed, and house dust was collected for the measurement of endotoxin and glucans. Atopic sensitization was defined by allergen-specific IgE levels in the serum. RESULTS: In multivariate analyses, helping with haying was the only variable related to a farming environment having a consistent inverse association with both current symptoms and a doctor's diagnosis of AE [aOR = 0.65 (95% CI: 0.46-0.93) and 0.73 (0.51-1.05)], respectively. Severe lower respiratory tract infections (LRTI) in the first 2 years of life and usage of antibiotics ever were found to be positively related only to asthma-associated AE, whereas the effect of LRTI on AE without asthma had an opposite effect. Levels of beta(1-->3)-glucans in mattress dust were inversely related to a doctor's diagnosis of asthma-associated AE [aOR = 0.75 (0.57-0.98)], and endotoxin levels to current symptoms of asthma-associated AE [aOR = 0.73 (0.57-0.94)]. CONCLUSIONS: The analyses of the PARSIFAL study revealed two different phenotypes of AE, depending on the association with asthma and wheezing ever. With regard to the hygiene hypothesis, help with haying, exposure to beta(1-->3)-glucans and endotoxin were found to be inversely associated with the AE phenotype associated with asthma and wheezing.     

Ovarian torsion in puerperium: A case report and review of the literature

INTRODUCTION

Ovarian torsion (OT) is a rare cause of acute abdominal pain that requires prompt recognition and treatment during puerperium. Diagnosis of OT can be challenging due to nonspecific clinical features and uncommon objective findings. The management of OT is often delayed because of diagnostic uncertainty. Early and timely recognition and prompt intervention are crucial to preserve ovarian function and to minimize morbidity.

PRESENTATION OF CASE

We report a 29-year-old postpartum woman who presented to the emergency department (ED) with severe right flank pain, nausea and anorexia initially considered as renal colic. After further investigation, OT caused by large mucinous cyst was diagnosed. Right-sided salpingo-oophorectomy was performed due to hemorrhagic ovary and huge cystic mass causing ischemic OT.

DISCUSSION

OT is often diagnosed based on the clinical presentation, including severe, sharp, sudden onset of unilateral lower abdominal pain and tenderness with a palpable laterouterine pelvic mass and nausea/vomiting. Emergency surgical intervention should be performed if OT is suspected to confirm the diagnosis and uncoil the twist to prevent ovarian damage.

CONCLUSION

In conclusion, emergency physicians should be aware of the possibility of OT in postpartum women. Therefore, early and timely surgical intervention should be undertaken.     

The relationship of Prohepcidin levels with anemia and inflammatory markers in non-diabetic uremic patients: a controlled study

Introduction: Hepcidin, a small peptide hormone synthesized in the liver, plays central role in regulation of iron metabolism. Hepcidin generation in chronic kidney disease (CKD) is dependent on iron status, anemia, inflammation, and hypoxia and erythropoietin levels. In our study, the relationship between Prohepcidin levels and inflammation and iron indices in non-diabetic uremic patients was investigated. Methods: This study has a cross-sectional design which includes four groups: Non-diabetic 21 patients with stage 4 CKD (predialysis), 20 hemodialysis (HD) and 21 peritoneal dialysis (PD) patients and 17 healthy volunteers as the control group. Complete blood count, iron, total iron binding capacity (TIBC), ferritin, high-sensitive C-reactive protein (hsCRP), fibrinogen, parathyroid hormone, interleukin (IL)-6 and Prohepcidin levels were recorded. Results: Serum Prohepcidin levels in the predialysis, HD, PD and the control groups were 119.6?±?45.1?ng/mL, 140.2?±?41.8?ng/mL, 148.2?±?35.0?ng/mL and 93.8?±?21.9?ng/mL, respectively (p?r?=?0.345, p?=?0.002), creatinine (r?=?0.465, p?r?=?0.253, p?=?0.025), hsCRP (r?=?0.275, p?=?0.019), duration of dialysis treatment (r?=?0.443, p?r?=?0.467, p?r?=?0.615, p?r?=??0.286, p?r?=??0.573, p?r?=??0.473, p?r?=??0.351, p?=?0.002) and hematocrit (r?=??0.342, p?=?0.002) levels. Discussion: Prohepcidin levels increase with deepening anemia and show positive correlation with inflammatory markers. Therapeutic interventions regarding Prohepcidin action on inflammatory status may play a role in the treatment of anemia due to inflammation. Functional iron deficiency is frequent in uremic patients. It may be beneficial to measure Prohepcidin level together with ferritin among these patients.     

Internalized Stigma in Pediatric Psoriasis: A Comparative Multicenter Study

BackgroundInternalized stigma, adoption of negative attitudes and stereotypes of the society regarding persons'' illness, has not been studied previously in pediatric psoriasis patients.ObjectiveWe aimed to investigate the internalized stigma in pediatric psoriasis patients and to determine differences according to factors affecting internalized stigma compared to adult psoriasis patients.MethodsThis multicenter, cross-sectional, comparative study included 125 pediatric (55 female, 70 male; mean age±standard deviation [SD], 14.59±2.87 years) and 1,235 adult psoriasis patients (577 female, 658 male; mean age±SD, 43.3±13.7 years). Psoriasis Internalized Stigma Scale (PISS), Dermatology Life Quality Index (DLQI), Perceived Health Status (PHS), and the General Health Questionnaire (GHQ)-12 were the scales used in the study.ResultsThe mean PISS was 58.48±14.9 in pediatric group. When PISS subscales of groups were compared, the pediatric group had significantly higher stigma resistance (p=0.01) whereas adult group had higher scores of alienation (p=0.01) and stereotype endorsement (p=0.04). There was a strong correlation between mean values of PISS and DLQI (r=0.423, p=0.001). High internalized stigma scores had no relation to either the severity or localization of disease in pediatric group. However, poor PHS (p=0.007) and low-income levels (p=0.03) in both groups, and body mass index (r=0.181, p=0.04) in the pediatric group were related to high PISS scores.ConclusionInternalized stigma in pediatric patients is as high as adults and is related to poor quality of life, general health, and psychological illnesses. Unlike adults, internalized stigma was mainly determined by psoriasis per se, rather than disease severity or involvement of visible body parts, genitalia or folds.
