Increased serum renalase in hemodialysis patients: is it related to left ventricular hypertrophy?

Introduction: Left ventricular hypertrophy (LVH) is one of the most common cardiac abnormalities in patients with end stage renal disease (ESRD). Hypertension, diabetes, increased body mass index, gender, age, anemia, and hyperparathyroidism have been described as risk factors for LVH in patients on dialysis. However, there may be other risk factors which have not been described yet. Recent studies show that renalase is associated with cardiovascular events. The aim of this study was to reveal the relation between renalase, LVH in patients under hemodialysis (HD) treatment.

Methods: The study included 50?HD patients and 35 healthy controls. Serum renalase levels and left ventricle mass index (LVMI) were measured in all participants and the relation between these variables was examined.

Findings: LVMI was positively correlated with dialysis vintage and C-reactive protein (CRP) (r?=?0.387, p?=?0.005 and r?=?0.597, p?r?=??0.324, p?=?0.022 and r?=??0.499, p?r?=?0.263, p?=?0.065). Serum renalase levels were significantly higher in HD patients (212?±?127?ng/mL) compared to controls (116?±?67?ng/mL) (p?r?=?0.677, p?r?=?0.625, p?Discussion: In our study, LVMI was correlated with dialysis vintage, residual diuresis, CRP, and hemoglobin. LVMI tends to correlate with renalase and this correlation may be significant in studies with more patient numbers. The main parameters affecting renalase levels are dialysis vintage and serum creatinine.     

Luteal phase support in intrauterine insemination cycles: a prospective randomized study of 300 mg versus 600 mg intravaginal progesterone tablet

Vaginal progesterone (P) has been suggested to be used for luteal phase support (LPS) in controlled ovarian stimulation (COH)–intrauterine insemination (IUI) cycles, however, no concensus exists about the best P dose. Therefore, considering the fecundability rate as the primary end point, our main objective was to find the optimal dose of P in COH–IUI cycles, comparing the two groups of women, each of which comprised of 100 women either on 300?mg or 600?mg of intravaginal P tablets, in a prospective randomized study design. The mean age of the women, duration of infertility, basal and day of hCG injection hormone levels in the female and sperm parameters were similar in the two study groups. Also, duration and dose of gonadotropin given, number of follicles, endometrial thickness, the total, ongoing and multiple pregnancy rates were comparable in both groups. We, therefore, claim that 300?mg of intravaginal micronized P should be the maximum dose of LPS in IUI cycles.     

Tenascin C levels in patients with mild and severe preeclampsia

Objective: To determine the serum tenascin-C (TN-C) levels in cases with mild and severe preeclampsia.

Methods: Pregnant women were divided into three groups, namely healthy pregnants (Group 1, n?=?20), pregnants with mild preeclampsia (Group 2, n?=?20) and pregnants with severe preeclampsia (Group 3, n?=?20). The groups were formed so as to match each other in terms of gestational week. From each pregnant woman, pre- and post-delivery blood samples were obtained to measure serum TN-C levels. The data were evaluated using the Kruskall–Wallis variance analysis. For the obtained values of p?<?0.05, the groups were compared in pairs. A p value of <?0.017 was accepted as significant.

Results: In Groups 1, 2 and 3, the prepartum TN-C levels were 5.02?±?0.4?µg/ml, 12.8?±?2.9?µg/ml and 33.8?±?11.7?µg/ml, and in the postpartum TN-C levels were 4.7?±?0.1?µg/ml, 11.7?±?1.8?µg/ml and 50.6?±?33.8?µg/ml, respectively. There was a significant difference between the groups in terms of the prepartum and postpartum TN-C levels (p?<?0.017, Mann–Whitney U [MWU] test). There was also a significant difference in the prepartum TN-C levels between Groups 2 and 3 (p?<?0.017, MWU test).

Conclusions: The prepartum and postpartum TN-C levels were significantly higher in mild and severe preeclampsia than those in healthy pregnants.     

Successful sleeve lobectomy of pediatric inflammatory myofibroblastic tumor

Inflammatory myofibroblastic tumor (IMT) is an uncommon solid tumor that was originally described in the lung. A 4‐year‐old girl was admitted to hospital with urticarial rash. On chest radiographs, an opacity was seen in the inferior zone of the left lung, and computed tomography showed a mass in the left lower lobe. Left lower sleeve lobectomy was performed, and the diagnosis was confirmed as IMT. Sleeve resection is the best option in lesions located in the mainstem bronchus or secondary carina. Herein, we present a rare case of IMT of the lung that was successfully treated with sleeve lobectomy. There have been fewer than 15 childhood cases of IMT reported in the literature, and the present 4‐year‐old patient is one of the youngest.     

Effects of multivitamin supplementation on DNA damage in lymphocytes from elderly volunteers

The aim of this study was to evaluate the effect of a mixture of vitamins and minerals on oxidative DNA damage and the resistance of DNA to H(2)O(2)-induced DNA strand breaks in lymphocytes from 80 elderly volunteers ex vivo by means of Comet assay. The intervention with vitamin complex decreased significantly the levels of DNA damage. Our results demonstrate that the vitamin complex was able to decrease H(2)O(2)-induced DNA breakage. Our data suggest that the consumption of some vitamins may reduce the effects of oxidative DNA damage and may be useful for attaining healthy aging.     

Cefuroxime-induced lupus

Drug-induced lupus erythematosus (DILE) is a syndrome that shares symptoms and laboratory characteristics with idiopathic systemic lupus erythematosus. Recognition of DILE is important because it usually reverts within a few weeks after stopping the offending drug. Antibiotics are uncommonly associated with DILE, and cefuroxime has never been incriminated as a cause. We present herein the first case of DILE induced by cefuroxime. Although this is the first report of cefuroxime-induced DILE, we should be aware of this occurrence.     

Sequential prevalence estimation with pooling and continuous test outcomes

Prevalence estimation is crucial for controlling the spread of infections and diseases and for planning of health care services. Prevalence estimation is typically conducted via pooled, or group, testing due to limited testing budgets. We study a sequential estimation procedure that uses continuous pool readings and considers the dilution effect of pooling so as to efficiently estimate an unknown prevalence rate. Embedded into the sequential estimation procedure is an optimization model that determines the optimal pooling design (number of pools and pool sizes) under a limited testing budget, considering the trade‐off between testing cost and estimation accuracy. Our numerical study indicates that the proposed sequential estimation procedure outperforms single‐stage procedures, or procedures that use binary test outcomes. Further, the sequential procedure provides robust prevalence estimates in cases where the initial estimate of the unknown prevalence rate is poor, or the assumed distribution of the biomarker load in infected subjects is inaccurate. Thus, when limited and unreliable information is available about the current status of, or biomarker dynamics related to, an infection, the sequential procedure becomes an attractive estimation strategy, due to its ability to mitigate the initial bias.
