Associations of the ITGB3 gene rs5918T>C and the APOA1 gene rs1799837C>T markers with serum lipid metabolism in coronary artery disease patients

Aim

The relationship between hypercholesterolemia, particularly elevated low density lipoprotein-cholesterol (LDL-C) levels and coronary artery disease is recognized by the evidence from previous epidemiologic studies. Importantly, genetic polymorphisms on different genes have been reported to be associated with plasma lipid levels. In this particular study, we aimed to investigate the relationship between the ITGB3 gene rs5918 T>C and APO-A1 gene rs1799837 C>T markers and serum lipid metabolism.

Patients and methods

A total of 100 subjects with CAD and 250 healthy subjects were involved in the current study. A basic biochemical analysis, including serum glucose, total serum cholesterol, HDL-C, LDL-C and triglycerides, was performed for each participant. Genotyping for the ITGB3 gene and APO-A1 gene polymorphisms was performed by polymerase chain reaction followed by restriction fragment length polymorphism (RFLP) analysis.

Results

With respect to the genotype and allele distributions of ITGB3 rs5918 T>C polymorphism, the frequency of the C allele was higher in the coronary artery disease (CAD) group compare to control group (p=0.001). Moreover, there was a statistically significant association detected between ITGB3 rs5918 CC genotype and serum total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C) (p=0.0006, p=0.016 respectively) in CAD group. However there was no statistically significant association was identified between the APOA1 rs1799837 C>T polymorphism and biochemical parameters in control and CAD group.

Conclusion

The results demonstrated that rs5918 T>C variant within the ITGB3 gene might have a clinical importance as a genetic marker which increases the susceptibility to CAD. Therefore, the ITGB3 gene rs5918 C allele may be offered as a screening option for CAD in Turkish Cypriot population who come in for medical check-up.

Mastalgia Due to Degenerative Changes of the Spine

BACKGROUND

Mastalgia is a common and enigmatic condition; the cause and optimal treatment are still inadequately defined. Cervical radiculopathy, which is the result of cervical nerve root pathology often caused by spaceoccupying lesions such as cervical disc herniation, spondylosis, or osteophytosis, is frequently encountered in physical therapy.

OBJECTIVES

The aim of the study was to evaluate the incidence of vertebral pathologies in patients with non-cyclic mastalgia and the efficacy of conservative treatment of these pathologies on relieving breast pain.

MATERIAL AND METHODS

One hundred patients were included in the study, all with breast pain continuing throughout the day and lasting at least three months. Breast and axillary physical examinations, mammographic and/or ultrasonographic evaluations were normal in all the patients. The patients' pain levels were scored using a visual analog scale (VAS). Cervical and thoracic spine magnetic resonance imaging (MRI) was performed on all the participants.

RESULTS

Among 96 patients that had pathological findings on magnetic resonance imaging (96%), 49 women had diffuse annular bulging of the cervical spine, and 47 had cervical disc protrusion. Additionally, 12 patients had thoracic disc protrusion. At the end of the three-month period, the patients who were given only conservative treatment returned for follow-up evaluations. According to the VAS scores, five patients had mild to moderate improvement, 55 showed significant improvement, and 29 achieved complete remission.

CONCLUSIONS

The authors concluded that if none of the known causes of breast pain are found in a patient, the patient should be evaluated for vertebral pathologies.

Comparison of the Effects of Plateletrich Plasma Prepared in Various Forms on the Healing of Dermal Wounds in Rats

OBJECTIVE

This study was designed to evaluate the effects of 3 different forms of platelet-rich plasma (PRP) on the healing process, wound healing rate, and histopathological changes that occur during recovery of open dermal wounds.

MATERIALS AND METHODS

A 2 cm x 1 cm full-thickness skin defect was made on the backs of 40 Wistar female rats that were divided into 4 groups of 10. In group 1 (control group), the wounds were cleaned with saline; in group 2, the wounds were covered with PRP gel obtained by single centrifugation; in group 3, the wounds were covered with liquid PRP obtained by double centrifugation; and in group 4, PRP gel obtained by double centrifugation with added thrombin was applied on the dermal wounds. All treatments were applied on postoperative days 1, 4, 7, and 10.

RESULTS

In all PRP groups, the wound closure was almost complete on day 14 while the wound contraction progressed more slowly in the control group. The mean histopathological scores of epithelialization, inflammation, and fibrosis were significantly better in all PRP groups than the scores in the control group.

CONCLUSION

In conclusion, although all PRP preparations had positive effects on dermal wound healing, double centrifuged PRP topical treatments (with or without thrombin activation) are more effective than single centrifuged PRP, and double centrifugation methods should be preferred for the preparation of PRP.

Evaluation of intraabdominal adhesion generating potentials of ankaferd and calcium alginate used as hemostatic agents

AIM

The present study aimed to evaluate intra-abdominal adhesion generating potential of Ankaferd Blood Stopper (ABS), which was used as postoperative hemostatic agent in the rats that underwent surgery, in comparison with Ca-alginate.

MATERIAL AND METHOD

Totally, 30 rats were randomized into 4 groups. In the control group, 1x1 cm peritoneum was removed from the right lower quadrant after cecal abrasion. In the other two study groups, the same procedure was performed after Ankaferd Blood Stopper and Ca-alginate application respectively. RESULTS were evaluated both histopathologically and by adhesion scoring methods. All results underwent statistical analysis.

RESULTS

Comparing overall results, no statistically significant difference was found between the sham, control, ABS and Ca-alginate groups (p = 0.099). Paired group comparisons revealed no statistically significant difference between the sham group and the control, ABS, and Ca-alginate groups (p = 0.222, p = 0.222, and p = 0.833 respectively). It was observed that there was no statistically significant difference between the control and ABS groups (p = 0.505), but there was a statistically significant difference between the control and Ca-alginate groups with Bonferroni correction (p = 0.028). Histopathological examination revealed no statistical difference between the groups.

CONCLUSION

In conclusion, intra-abdominal adhesion generating potentials of Ca-alginate and ABS were experimentally evaluated and macroscopic and microscopic comparisons revealed no significant difference between sham, control, Ca-alginate, and ABS groups (Fig. 8, Ref. 36). Text in PDF www.elis.sk. agent.

Diffusion tensor magnetic resonance imaging in patients with multiple sclerosis and its relationship with disability

Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system. Diffusion tensor magnetic resonance imaging (DTI) can yield important information on the in vivo pathological processes affecting water diffusion. The aim of this study was to quantitatively define water diffusion in normal-appearing white matter (NAWM) distant from the plaque, in the plaque, and around the plaque, and to investigate the correlation of these changes with clinical disability. Conventional MRI and DTI scans were conducted in 30 patients with MS and 15 healthy individuals. Fractional anisotropy maps and visible diffusion coefficients were created and integrated with T2-weighted images. Regions of interest (ROIs) were placed on the plaques on the same side, white matter around the plaques and NAWM on the opposite side. Only the white matter of healthy individuals in the control group, and FA and ADC values were obtained for comparison. The highest FA and lowest ADC were detected in the control group at the periventricular region, cerebellar peduncle and at all ROIs irrespective of location. There was a significant difference in comparison to the control group at all ROIs in patients with MS (p < 0.001 for all comparisons). No significant correlation between diffusion parameters and expanded disability state scale (EDSS) scores was found in patients with MS. DTI may provide more accurate information on the damage due to the illness, compared to T2A sequences, but this damage may not be correlated with the clinical disability measured by EDSS score.

Determinants of the intention of preconception care use: lessons from a multi-ethnic urban population in the Netherlands

OBJECTIVES

To investigate the determinants of the intention of preconception care use of women in a multi-ethnic urban population.

METHODS

The ASE-model-a health behaviour model-was used as an explanatory framework. A representative sample was taken from the municipal population registers of two districts in Rotterdam, the Netherlands, 2009-2010. 3,225 women (aged 15-60 years) received a questionnaire, which was returned by 631: 133 Dutch, 157 Turkish and Moroccan, and 341 Surinamese and Antillean. Descriptive, univariate and multivariate analyses were performed.

RESULTS

The multiple logistic analyses showed that intention to attend preconception care was significantly higher in women with a Turkish and Moroccan background (β 1.02, P = 0.006), a higher maternal age (β 0.04, P = 0.008) and a positive attitude (β 0.50, P < 0.001). Having no relationship (β -1.16, P = 0.004), multiparity with previous adverse perinatal outcome (β -1.32, P = 0.001), a high educational level (β -1.23, P = 0.03), having paid work (β -0.72, P = 0.01) and experienced barriers level (β -0.15, P = 0.003) were associated with less intention to use preconception care.

CONCLUSIONS

Modifiable determinants as attitude and barriers can be addressed to enhance preconception care attendance.

Does the presence of a mesh have an effect on the testicular blood flow after surgical repair of indirect inguinal hernia?

PURPOSE

Modern treatment of inguinal hernias includes prosthetic mesh repairs. However, direct contact of the mesh to the vessels in the inguinal canal and perimesh fibrosis may have a negative impact on testicular flow. The aim of this prospective study was to evaluate the effect of mesh implantation/perimesh fibrosis on testicular flow after repair of indirect inguinal hernias (IIHs).

METHOD

Forty-eight male patients with unilateral IIH were included. Both testicular parenchyma were assessed using gray-scale sonography, and color/spectral Doppler sonography was performed to evaluate testicular arterial impedance, perfusion, and venous flow. Measurements were made bilaterally at the level of the inguinal canal 1 day before and at the end of the 2nd month after the operation.

RESULTS

There was no difference in testicular and echotexture perfusion between the hernia and the control sides pre- and postoperatively. No venous thrombosis was found. In all groups, resistance index and pulsatility index, measured at 4 levels, were highest in the proximal inguinal canal and lowest at the extratesticular-intrascrotal level (p < 0.05). For all Doppler parameters there was no significant difference between the pre- and postoperative measurements on both the hernia and the control sides.

CONCLUSION

Mesh implantation/perimesh fibrosis does not adversely affect ipsilateral testicular flow. Mesh application is still a safe procedure in male patients in whom testicular function is important.

Bias and precision of cholesterol analysis by physician's office analyzers

We studied the bias and precision of serum cholesterol analysis by physician's office analyzers. Total imprecision (CV range, %) for analysis of serum pools was: Abbott Vision 1.5%-1.9%; Ames Seralyzer 3.9%-4.5%; BMD Reflotron 2.3%-3.8%; Chrometrics Cholesterol Test System 2.3%-2.8%; Kodak DT-60 1.6%-2.2%. The Ames Seralyzer exhibited an excessive between-run component of variation. We collected, from 109 volunteers, samples of venous serum, heparin-treated whole blood, heparin-treated plasma, and fingerstick whole blood, and analyzed each type (where possible) with each system; serum was also analyzed in duplicate (by a proposed Reference Method) at the Centers for Disease Control. For assays with serum, the BMD Reflotron and Kodak DT-60 exhibited negative bias. All systems gave lower results for plasma and whole blood than for serum. All systems except the Kodak DT-60 were less precise for analysis of patients' sera than for analysis of serum pools; between-specimen variables may influence the results of these systems.
