Determination of macro and trace element levels of serum, tears, saliva, and hair samples in kilis goats with icp-ms

This study is focused on the evaluation of macro and trace elements concentration including sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), copper (Cu), zinc (Zn), selenium (Se), nickel (Ni), titanium (Ti), manganese (Mn), cobalt (Co), and chromium (Cr) of the serum, saliva, tears, and hair samples in Kilis goats. The study involved 33 goats without clinical signs of disease. Individual serum, saliva, tears, and hair samples from each goat were collected for element quantifications through the inductively coupled plasma mass spectrometry (ICP-MS) method after acid digestion in a microwave system. Element concentrations varied and depended on the sample type. The most predominant element in serum and saliva samples was Na (3559±55.2 and 3265±53.6 mg/L, respectively), followed by K>Ca>Mg. Potassium was the most abundant element analyzed in tears and hair samples (3506±305 and 4664±100.5 mg/L, respectively). The major trace element was Fe in all sample types except hair samples. Nickel was detected only in serum samples (83.9±6.35 μg/L) and Mn was detected only in hair samples (12903±3142 μg/L). In all samples, Co was below the detection limit. There was a significant correlation of some elements between serum and hair (Na, K, Mg, Cu), tears and hair (K, Mg, Fe), serum and tears (K) samples. Trace elements concentration did not pose a risk for deficiency or excess. It was concluded that tears and saliva are potential alternative materials for element analysis and simultaneous tears, saliva, and hair along with serum could be useful in predicting the inorganic metabolic status of goats

Analyses of Essential Elements and Heavy Metals by Using ICP-MS in Maternal Breast Milk from Şanlıurfa, Turkey

Maternal breast milk is a unique biological matrix that contains essential micronutrients. Potentially heavy metals may also affect infants’ health and growth through maternal breast milk. The purpose of this study was to determine and compare the essential elements and heavy metals of maternal breast milk of nursery mothers residing in Şanlıurfa province, Turkey. Maternal breast milk concentrations of sodium, magnesium, phosphorus, potassium, calcium, iron, copper, zinc, arsenic, and lead were analyzed in a random sample of the first time in urban and suburban nursery Turkish mothers (n: 42). Eight essential elements and two heavy metals were analyzed using ICP-MS after microwave digestion. For bivariate analyses of variables, we use nonparametric Spearman’s correlation coefficient test. The mean concentrations of essential elements and heavy metals were as follows: sodium 330 ± 417 mg/L, magnesium 32.6 ± 15.5 mg/L, phosphorus 156 ± 46.2 mg/L, potassium 488 ± 146 mg/L, calcium 193 ± 53.2 mg/L, iron 1.65 ± 1.43 mg/L, copper 0.54 ± 0.46 mg/L, zinc 2.89 ± 3.23 mg/L, arsenic < 1 μg/L, and lead < 1 μg/L. Concentrations of heavy metals in maternal breast milk may have the important implication that it is not affected by environmental pollution in this province. This study provides reliable information about maternal breast milk concentrations of nursery mothers residing in Şanlıurfa, Turkey, and also compares the relations between essential elements and socioeconomic conditions, residing areas, and using copper equipment for food preparation of which some have not previously been reported

Romatoid Artrit ve Ankilozan spondilitte vitamin D’nin hastalık aktivitesi ile ilişkisi

Amaç: Vitamin D eksikliğinin, romatoid artrit (RA) ve ankilozan spondilit (AS) gibi otoimmun hastalıklarda başlatıcı bir neden mi yoksa hastalık aktivitesiyle ilişkili mi olduğu hala merak edilen bir konudur. Çalışmamızın amacı, Th1 baskın hastalıklardan olan RA ve AS hastalarında serum vitamin D seviyeleri ile hastalık aktiviteleri arasındaki ilişkiyi değerlendirmektir. Gereç ve Yöntem: Çalışmamız, retrospektif olarak 92 RA’li hasta, 100 AS’li hasta ve 62 sağlıklı kontrolün dosyalarından elde edilmiş bilgileri içermektedir. Çalışmaya alınanların yaşı, cinsiyeti, hastalık süreleri, kullandığı ilaçlar, vitamin D seviyeleri, kalsiyum, C-reaktif protein (CRP) ve eritrosit sedimentasyon hızı (ESH) değerleri kayıt edildi. Hastalık aktiviteleri RA’li hastalarda hastalık aktivite skoru-28 (DAS28) ile, AS’li hastalarda ise bath ankilozan spondilit hastalık aktivite indeksi (BASDAİ) ile değerlendirildi. Bulgular: Vitamin D seviyeleri tüm gruplarda düşüktü. AS hastalarında, vitamin D seviyeleri ile BASDAİ, ESH ve CRP arasında istatiksel olarak negatif korelasyon yoktu (sırasıyla, r=-0.059, p=0.560, r=-0.072, p=0.473, r=-0.112, p=0.268). RA’li hastalarda ise vitamin D düzeyi ile DAS28 arasında anlamlı negatif korelasyon yoktu (r=-0.090, p=0.392). Tartışma: Çalışmamızda, tüm gruplarda vitamin D seviyeleri düşük bulundu ve bu vitamin D eksikliğinin, RA ve AS’in etyolojisinden ziyade hastalık aktivitesi ile ilişkili olabileceğini akla getirmektedir.Aim: Vitamin D deficiency in autoimmune disorders such as rheumatoid arthritis (RA) and ankylosing spondylitis (AS), whether an initiator cause or associated with disease activity is still wondered. The aim of our study is to investigate the association between serum vitamin D levels and disease activity in subjects with RA and AS which are known to be Th1 dominant diseases. Material and Method: The study included the data of 92 patients with RA, 100 patients with AS and 62 healthy controls, which were retrospectively obtained from the patient files. The age, gender, duration of the disease, medications, levels of vitamin D, calcium, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were recorded. Disease activities were evaluated by Disease Activity Score-28 (DAS28) in patients with RA and Bath Ankylosing Spondylitis Disease Index (BASDAI) in patients with AS. Results: Vitamin D levels were low in all groups. In AS patients, there was no statistical negative correlation among vitamin D levels and BASDAI, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) (r=-0.059, p=0.560, r=-0.072, p=0.473, r=-0.112, p=0.268, respectively). In RA patients, there was also no significant negative correlation between vitamin D levels and DAS28 (r=-0.090, p=0.392). Discussion: In our study, low serum vitamin D levels were found in all groups, and it is suggested that vitamin D deficiency may be associated with the disease activity rather than the etiology of RA and AS

Efficacy of subsequent treatments in patients with hormone-positive advanced breast cancer who had disease progression under CDK 4/6 inhibitor therapy.

Background There is no standard treatment recommended at category 1 level in international guidelines for subsequent therapy after cyclin-dependent kinase 4/6 inhibitor (CDK4/6) based therapy. We aimed to evaluate which subsequent treatment oncologists prefer in patients with disease progression under CDKi. In addition, we aimed to show the effectiveness of systemic treatments after CDKi and whether there is a survival difference between hormonal treatments (monotherapy vs. mTOR-based). Methods A total of 609 patients from 53 centers were included in the study. Progression-free-survivals (PFS) of subsequent treatments (chemotherapy (CT, n:434) or endocrine therapy (ET, n:175)) after CDKi were calculated. Patients were evaluated in three groups as those who received CDKi in first-line (group A, n:202), second-line (group B, n: 153) and >= 3rd-line (group C, n: 254). PFS was compared according to the use of ET and CT. In addition, ET was compared as monotherapy versus everolimus-based combination therapy. Results The median duration of CDKi in the ET arms of Group A, B, and C was 17.0, 11.0, and 8.5 months in respectively; it was 9.0, 7.0, and 5.0 months in the CT arm. Median PFS after CDKi was 9.5 (5.0-14.0) months in the ET arm of group A, and 5.3 (3.9-6.8) months in the CT arm (p = 0.073). It was 6.7 (5.8-7.7) months in the ET arm of group B, and 5.7 (4.6-6.7) months in the CT arm (p = 0.311). It was 5.3 (2.5-8.0) months in the ET arm of group C and 4.0 (3.5-4.6) months in the CT arm (p = 0.434). Patients who received ET after CDKi were compared as those who received everolimus-based combination therapy versus those who received monotherapy ET: the median PFS in group A, B, and C was 11.0 vs. 5.9 (p = 0.047), 6.7 vs. 5.0 (p = 0.164), 6.7 vs. 3.9 (p = 0.763) months. Conclusion Physicians preferred CT rather than ET in patients with early progression under CDKi. It has been shown that subsequent ET after CDKi can be as effective as CT. It was also observed that better PFS could be achieved with the subsequent everolimus-based treatments after first-line CDKi compared to monotherapy ET
