Objective: This study was conducted to investigate the effect of transport stress on physiological and hematological responses and milk performance in lactating dairy cows. Methods: Ten lactating dairy cows were randomly divided into 2 groups. The treatment group (TG) was transported 200 km for 4 h by truck, and the control group (NTG) was restrained by stanchion for 4 h in Konkuk University farm. Blood and milk samples were collected at 24 h pre-transport; 1, 2, and 4 h during transport; and 2, 24, and 48 h post-transport. Milk yields were measured at 24 h pre-transport, 0 h during transport, and 24, 48, and 72 h post-transport. Results: Leukocyte, neutrophil, and monocyte numbers in the TG were significantly higher than those of the NTG at each experimental time point. Lymphocyte numbers in the TG were significantly (p<0.05) higher than those of the NTG at 48 h post-transport. Additionally, the neutrophil:lymphocyte ratio of the TG was 45% and 46% higher than that of the NTG at 4 h during transport and 2 h post-transport, respectively. There were no significant differences in erythrocyte numbers, hemoglobin concentrations, platelet numbers, and hematocrit percentages between two groups. Cortisol levels in the TG were significantly (p<0.05) higher than those in the NTG. Milk yields in the TG were lower than those in the NTG. The somatic cell count (SCC) of the TG was significantly (p<0.05) higher than that of the NTG at 1 and 2 h during transport; that of the TG increased dramatically at 1 h during transport and gradually decreased subsequently. Conclusion: Transport stress increased blood parameters including leucocyte, neutrophil, and monocyte numbers by increased cortisol levels, but did not affect erythrocytes, hemoglobin and hematocrit levels. Additionally, transport resulted in a decrease in milk yield and reduced milk quality owing to an increase in milk SCC.

Background: Systemic inflammatory response was shown to play an important role in development and progression of many cancer types and different inflammation-based indices were used for determining prognosis. We aimed to investigate the prognostic effects of neutrophil to lymphocyte ratio (NLR) and prognostic nutritional index (PNI) in patients with non-small cell lung cancer (NSCLC). Materials and Methods: NSCLC patients diagnosed in our institution were retrospectively reviewed. Demographic and clinicopathologic characteristics were recorded. NLR and PNI was calculated before the application of any treatment. Results: A total of 138 patients were included in the study. Patients were divided into two groups according to NLR (<3.24 or ${\geq}3.24$) and PNI (<49.5 or ${\geq}49.5$). While median overall survival was 37.0 (95% CI 17.5-56.5) months in the group with low NLR, it was calculated as 10.0 (95%CI 5.0-15.0) months in the group with high NLR (p<0.0001). While median overall survival was 7.0 (95%CI 3.5-10.5) months in the group with low PNI, it was calculated as 33.0 (95% CI 15.5-50.4) months in the group with high PNI (p<0.0001). Stage, NLR and PNI levels were evaluated as independent risk factors for overall survival for all patients in multivariate analysis (p<0.0001, p=0.04 and p<0.001, respectively). Conclusions: NLR (${\geq}3.24$) and PNI (<49.5) at diagnosis is an independent marker of poor outcome in patients with NSCLC. NLR and PNI is an easily measured, reproducible prognostic tests that could be considered in NSCLC patients.

This experiment was conducted to examine the effects of cage type (CT) and cage density (CD) on physiological variables in growing rats. Sprague Dawley rats (n=108) weighing an average of 46 g were housed in metallic cage with woodchip bedding (MCWB), metallic cage with wire mesh (MCWM), and plastic shoebox with woodchip bedding (PCWB) separately by sex at normal ($160-cm^2/rat$, ND) and high ($80-cm^2/rat$, HD) CD from 3 to 10 wks of age. All cages were in dimension of $24{\times}40{\times}20$ cm ($W{\times}D{\times}H$). At the end of the experiment, blood samples were collected and 6 rats from each cage were sacrificed. No death was observed among rats at ND, whereas mortality rate at HD was 22.3% for males and 13.9% for females. Heart weight was affected by CT. Doubling CD caused 23, 11.8, 17.9, 8.6, 6.9, and 16.4% decreases in BW and weights of heart, liver, kidney, testis, and ovary, respectively. Except for adrenal gland, other organs for males were heavier than for females. Liver weight of males and females responded differently to CT and CD. Comparing with females, males had 7.3 and 5.2% heavier and 9.9% lighter liver weights in MCWB, MCWM, and PCWB, respectively. As CD doubled, liver weight for males and females decreased by 22.4 and 13.1%, respectively. Mean adrenal gland weight increased by 8.4% and decreased by 9.7% for males and females, respectively, with doubling CD. CT affected glucose, TG, Ca, and ALP levels. However, CD did not alter blood chemistry. Rats housed in metallic cages had greater neutrophil count and neutrophil:lymphocyte ratio than rats housed in plastic cages. Doubling CD caused a 24.2% increase in lymphocyte count. There were CT by CD, CT by sex, and CD by sex interaction effects on lymphocyte count. Doubling CD caused 0.1% decrease and 49.8 and 26.7% increases in lymphocyte count for rats housed in MCWB, MCWM, and PCWB, respectively. Comparing with females, lymphocyte count for males housed in MCWB, MCWM, and PCWB had 8.9 and 12.9% greater and 30.3% less lymphocyte counts, respectively. Lymphocyte count decreased by 4.12% for males, whereas it increased by 61.0% for females as CD doubled. Doubling CD resulted in 2.5 and 2.3% increases in erythrocyte count and hematocrit value. These data suggest that animals perform better in metallic cages than in plastic cages and that cage density had pronounceable effects on physiological parameters in a cage type and sex dependent-manner.

Bacteremia and sepsis are common causes of morbidity and mortality worldwide, with incorrect or delayed diagnoses being associated with increased mortality. New tests or markers that allow a more rapid and less costly detection of bacteremia and sepsis have been investigated. The aim of this study was to clarify the cutoff value of the neutrophillymphocyte ratio (NLR) according to procalcitonin (PCT) level in the decision-making processes for bacteremia and sepsis. In addition, other white blood cell subgroup parameters, which are assessed in all hospitals, for bacteremia and sepsis were explored. This retrospective study included 1,468 patients with suspected bacteremia and sepsis. Patients were grouped according to the following PCT criteria: levels <0.05 ng/ml (healthy group), 0.05-0.5 ng/ml (local infection group), 0.5-2 ng/ml (systemic infection group), 2-10 ng/ml (sepsis group), and >10 ng/ml (sepsis shock group). One important finding of this study, which will serve as a baseline to measure future progress, is the presence of many gaps in the information on pathogens that constitute a major health risk. In addition, clinical decisions are generally not coordinated, compromising the ability to assess and monitor a situation. This report represents the first study to determine the limits of the use of NLR in the diagnosis of infection or sepsis using a cutoff value of <5 when sufficient exclusion criteria are used.

Objective: The aim of the present study was to evaluate the associations between hematologic parameters related to systemic inflammation and insulin resistance-associated metabolic parameters in women with polycystic ovary syndrome (PCOS). Methods: Eighty-two women between the ages of 18 and 35 years who were diagnosed with PCOS were included in this study. A 2-hour 75-g oral glucose tolerance test (OGTT) was administered to all study participants; fasting and postprandial glucose and insulin levels were measured simultaneously during the 2-hour OGTT. Hematologic parameters were derived from a standard complete blood count and a differential count of fasting-state blood samples. The correlations between hematologic parameters and insulin resistance-associated clinical and metabolic parameters were evaluated using the Spearman rank correlation and partial correlation coefficients. Hematologic parameters related to systemic inflammation were compared between the two groups, categorized by the presence or absence of insulin resistance. Results: Significant differences in the absolute neutrophil count, absolute monocyte count, platelet count, and neutrophil-lymphocyte ratio were found between the insulin-resistant group and insulin-nonresistant group. Correlation analysis found that all hematological parameters, except for the platelet-lymphocyte ratio, were associated with at least one insulin resistance-associated metabolic parameter. However, these significant correlations between hematological and metabolic parameters were attenuated after controlling for the effects of other covariates using partial correlation analysis. Conclusion: The association between hematologic parameters indicative of systemic inflammation and insulin resistance-associated metabolic parameters seems to be strongly influenced by other anthropometric covariates in women with PCOS.

유기인계 살충제를 음독하였을 경우 임상적으로 치명적인 결과를 가져올 수 있다. 이 연구는 유기인계 살충제 음독으로 인해 사망한 환자와 생존한 환자들의 내원 당시 중성구/림프구 비율을 비교 분석하여 사망률을 얼마나 예측할 수 있는지 알아보기 위해 시행되었다. 연구 자료는 전자의무기록에서 추출하였고, 2008년 1월부터 2018년 11월까지 유기인계 살충제를 음독하고 일개 응급실에 내원한 환자들(150명)을 생존 군(135명)과 사망 군(15명)으로 분류하고 후향적으로 비교 분석하였다. 환자들의 특성(나이, 성별, 기저질환 유무, 음독 후 병원까지 걸린 시간, 음독 양), 혈액검사 결과들과 의학적 중증도에 대한 개별 변수들을 먼저 비교한 후, 유의한 차이를 보이는 변수(나이, 혈중 백혈구 수, 아밀라아제 농도, 크레아티닌 농도, APACHE II점수 및 중성구/림프구 비율) 들에 대해 로지스틱 회귀분석을 시행하였다. 연구결과 나이, APACHE II 점수 및 중성구/림프구 비율이 사망 군에서 생존 군에 비해 유의하게 높았다. 이들 중 중성구/림프구 비율은 응급실에 내원하면 기본적으로 시행하는 전혈 검사를 통해 30분 이내에 신속하고 간단하게 얻을 수 있는 예측 인자이다. 본 연구를 통해 사망을 예측하는 도구로 중성구/림프구 비율이 유용하게 사용될 수 있으며, 특히, 수치가 10 이상으로 높은 경우 환자가 사망할 확률이 높음을 인지하고 집중 감시 및 치료를 해야 할 근거를 제시해 줄 수 있을 것으로 생각된다.

Background: This study aimed to determine the demographical distribution, survival and prognostic factors for neuroendocrine tumors monitored in our clinic. Materials and Methods: Data for 52 patients who were admitted to Cumhuriyet University Medical Faculty Training Research and Practice Hospital Oncology Center between 2006 and 2012 and were diagnosed and treated for neuroendocrine tumors were investigated. Results: Of the total, 30 (58%) were females and 22 (42%) were males. The localization of the disease was gastroenteropancreatic in 29 (56%) patients and other sites in 23 (44%). The most frequently involved organ in the gastroenteropancreatic system was the stomach (n=10, 19%) and the most frequently involved organ in other regions was the lungs (n=10, 19%). No correlation was found between immunohistochemical staining for proteins such as chromogranin A, synaptophysin, and NSE and the grade of the tumor. The patients were followed-up at a median of 24 months (1-90 months). The three-year overall survival rate was 71%: 100% in stage I, 88% in stage II, 80% in stage III, and 40% in stage IV. The three-year survival rate was 78% in tumors localized in the gastroenteropancreatic region, and 54% in tumors localized in other organs. In the univariate analysis, gender, age, performance status of the patients, grade, localization, surgical treatment, and neutrophil/lymphocyte ratio (${\leq}5$ versus >5) affected the prognosis of the patients. Conclusions: Most of the tumors were localized in the gastroenteropancreatic region, and the three-year survival rate in tumors localized in this region was better than the tumors localized in other sites. Surgical treatment was a positive independent prognostic factor, whereas Grade 3 and a neutrophil/lymphocyte ratio of >5 were negative independent prognostic factors.

Background: To evaluate factors for predicting the granulosa cell tumor of the ovary (GCTO) pre-operatively. Materials and Methods: This retrospective designed study was conducted on 34 women with GCTO as the study group and 76 women with benign ovarian cysts as the control group. Data were recorded from the hospital database and included age, body mass index (BMI), parity, serum estradiol ($E_2$) levels, diameter of the mass, ultrasonographic features, serum CA125 level, risk of malignancy index (RMI), duration of menopause, postoperative histopathology result, and the neutrophil/lymphocyte ratio (NLR). Results: The demographic parameters showed no statistically significant difference between the groups. Preoperative diameter of the mass, CA125, duration of menopause, and neutrophil/lymphocyte ratio were significantly different between the groups. ROC curve analysis demonstrated that diameter of the mass, serum estradiol and Ca125 levels, RMI and NLR may be discriminative factors in predicting GCTO preoperatively. Conclusions: In conclusion, we think that a careful preoperative workshop including diameter of the mass, serum estradiol ($E_2$) and Ca125 levels, RMI and NLR may predict GCTO and may prevent incomplete approaches.

Objective : The association of cancer survival and components of the systemic inflammatory response, combined to form inflammation-based prognostic scores (modified Glasgow Prognostic Score (GPS), Neutrophil Lymphocyte Ratio, Platelet Lymphocyte Ratio) is reviewed in this article. Methods and Results : With extensive research of papers in the PubMed, there is good evidence that preoperative measures of the systemic inflammatory response predict cancer survival, independent of tumor stage, in primary operable cancer. GPS also shows its prognostic value as a predictor of survival, independent of tumor stage, performance status and treatment in a variety of advanced cancer. GPS is associated with chemotherapy related toxicities as well as response to treatment and C-reactive protein shows its clinical value as a monitor of chemotherapy response. The systemic inflammatory response is closely related to cachexia and may be suitable measure for the clinical definition of cancer cachexia. Conclusion : Anticipated survival using the inflammation-based prognostic score is a major factor to be taken into consideration when deciding whether active intervention including surgery and chemotherapy or palliation therapy including acupuncture and herb medication is appropriate.
