The article explores the correlation strength of the ten most important cryptocurrencies, emphasizing the examination of differences during the periods of rising and falling prices. The daily and weekly returns of selected cryptocurrencies are taken as the basis for calculating and determining the correlation strength using the Pearson correlation coefficient. The survey covers the period from the beginning of 2017 to Bitcoin’s last local bottom in mid-March 2020. Research findings are as follows: 1) the most important cryptocurrencies are mostly moderately positively correlated with each other over time; 2) correlation strength decreases slightly during the bull period, but mostly remain in the range of moderate correlation; 3) correlation strength increases significantly during the bear period, with most cryptocurrencies strongly correlated with each other. The results do not change significantly if the daily or weekly cryptocurrency returns are used as the basis. A strong correlation in the period of falling prices prevents the effective diversification of the cryptocurrency portfolio, which must be considered when investing funds in the cryptocurrency market.

Abstract Background: Estimation of serum concentrations of free testosterone (FT) and bioavailable testosterone (bioT) by calculation is an inexpensive and uncomplicated method. We compared results obtained with 5 different algorithms. Methods: We used 5 different published algorithms [described by Sodergard et al. (bioTS and FTS), Vermeulen et al. (bioTV and FTV), Emadi-Konjin et al. (bioTE), Morris et al. (bioTM), and Ly et al. (FTL)] to estimate bioT and FT concentrations in samples obtained from 399 independently living men (ages 40–80 years) participating in a cross-sectional, single-center study. Results: Mean bioT was highest for bioTS (10.4 nmol/L) and lowest for bioTE (3.87 nmol/L). Mean FT was highest for FTS (0.41 nmol/L), followed by FTV (0.35 nmol/L), and FTL (0.29 nmol/L). For bioT concentrations, the Pearson correlation coefficient was highest for the association between bioTS and bioTV (r = 0.98) and lowest between bioTM and bioTE (r = 0.66). FTL was significantly associated with both FTS (r = 0.96) and FTV (r = 0.88). The Pearson correlation coefficient for the association between FTL and bioTM almost reached 1.0. Bland-Altman analysis showed large differences between the results of different algorithms. BioTM, bioTE, bioTV, and FTL were all significantly associated with sex hormone binding globulin (SHBG) concentrations. Conclusion: Algorithms to calculate FT and bioT must be revalidated in the local setting, otherwise over- or underestimation of FT and bioT concentrations can occur. Additionally, confounding of the results by SHBG concentrations may be introduced.

Background: Diabetes is a global epidemic with serious complication and there is a clear need for paying special attention to self-management as the cornerstone to optimal control of the disease. Objectives: This study aimed to assess the self-management status and its correlation to disease control indicators in people with diabetes. Methods: In a descriptive cross-sectional study, 220 patients were selected from the list of the referred patients available in Lamerd public health network from December 2014 to June 2015. In the first step, data about demographic information and disease control were collected from the patients’ records. In the second step, the self-management status of each patient was assessed by the Diabetes Self-Management Questionnaire developed by Schmitt et al. To analyze the data, independent sample t-test and Pearson correlation coefficient were used. Results: The mean age of the male and female participants was 56.43 ± 13.50 and 56.46 ± 10.49 years old, respectively. The mean duration of the disease was 6.67 ± 4.72 years for men and 7.07 ± 5.30 years for women. Twenty-one (25.9%) men and 60 (43.7%) women had a history of smoking. The results of the Pearson correlation coefficient showed that there was an inverse and statistically significant relationship between diabetes self-management status and weight, body mass index (BMI), waist circumference, glucose tolerance test (GTT), LDL, and cholesterol. The results of the t-test did not show significant differences between the level of HbA1C (HbA1C7) and self-management scores of the patients (P > 0.05). Conclusions: Patients with better self-management status were in a better disease control condition with respect to weight, BMI, waist circumference, GTT, LDL, and cholesterol levels. Special attention to the control and management of LDL, cholesterol, HbA1C, BMI, and blood pressure levels is recommended in planning for these patients.

Sarcopenia is associated with poor outcomes in a variety of conditions, including malignancy. Abdominal skeletal muscle area (SMA) segmentation using computed tomography (CT) has been shown to be an accurate surrogate for identifying sarcopenia. While magnetic resonance imaging (MRI) segmentation of SMA has been validated in cadaver limbs, few studies have validated abdominal SMA segmentation using MRI at lumbar level mid-L3. Our objective was to assess the reproducibility and concordance of CT and MRI segmentation analyses of SMA at mid-L3. This retrospective analysis included a random sample of 10 patients with renal cell carcinoma (RCC) and CT abdomen/pelvis, used to assess intra-observer variability of SMA measurements using CT. An additional sample of 9 patients with RCC and both CT and T2-weighted (T2w) MRI abdomen/pelvis was used to assess intra-observer variability of SMA using MRI and concordance of SMA between MRI and CT. SMA was segmented using Slice-O-Matic. SMA reproducibility was assessed using intraclass correlation coefficient (ICC). SMA concordance was analyzed using Bland–Altman plot and Pearson correlation coefficient. The intra-observer variability of CT and MRI SMA at mid-L3 was low, with ICC of 0.998 and 0.985, respectively. Bland–Altman analysis revealed bias of 0.74% for T2w MRI over CT. The Pearson correlation coefficient was 0.997 (p < 0.0001), demonstrating strong correlation between CT and T2w MRI. Abdominal SMA at mid-L3 is reproducibly segmented for both CT and T2w MRI, with strong correlation between the 2 modalities. T2w MRI can be used interchangeably with CT for assessment of SMA and sarcopenia. This finding has important clinical implications.

Background: Anemia during pregnancy is linked to major maternal and fetal problems. The aim of the study was to find any correlation between maternal anemia and neonatal cord blood haemoglobin (Hb) levels.Methods: This cross-sectional study was done in the department of pediatrics and department of obstetrics and gynaecology at the Hind Institute of Medical Sciences, Barabanki over 9 months from January 2021 to September 2021. A total of 308 pregnant females more than 34 weeks of gestation who delivered participated in the study and cord blood hemoglobin of their new-born was collected. The mean maternal hemoglobin and mean cord blood hemoglobin were compared using the Pearson correlation coefficient in different groups i.e., non-anemic, anemic, mild, moderate, and severe anemic groups.  Results: Out of 308 pregnant women, 198 (64.3%) were anemic, and 110 (35.7%) were nonanemic. The mean maternal hemoglobin among non-anemic mothers and anemic mothers was 11.91 (0.70) and 9.14 (1.56) respectively. The Pearson correlation coefficient of non-anemic, anemic, mild, moderate, and severe anemic groups were 0.6985, 0.8453, 0.7772, 0.6321, and 0.7226 respectively with a statistically significant p value<0.05 showing a positive correlation between maternal hemoglobin and cord hemoglobin.Conclusions: From this study, we concluded that maternal anemia affects neonatal cord blood hemoglobin. According to the findings, anemic women deliver new-born with lower hemoglobin levels than non-anemic mothers. The findings revealed a linear correlation between maternal hemoglobin and cord blood hemoglobin of their new-born.

AbstrakObesitas dapat dialami oleh semua golongan usia, maupun jenis kelamin. Kemajuan teknologi memberikan dampat positif dan negatif. Dampak positifnya banyak kegiatan menjadi lebih praktis dan cepat, sedangkan dampak negatifnya manusia menjadi semakin malas untuk bergerak. Berkurangnya aktivitas fisik mangakibatkan penyimpanan energi yang tersimpan dalam jaringan lemak, yang menyebabkan kegemukan. Tujuan dari penelitian ini adalah untuk mengetahui dan menganalisis hubungan antara aktivitas fisik dengan obesitas di Puskesmas Tegalrejo Kota Salatiga Jawa Tengah. Jenis penelitian yang digunakan yaitu penelitian deskriptif kuantitatif. Responden adalah pasien aktif di Posyandu Puskesmas Tegalrejo. Jumlah responden sebanyak 59 orang. Data yang diperoleh dalam penelitian ini adalah data primer dan data sekunder. Berdasarkan uji korelasi Indeks Massa Tubuh (IMT) terhadap nilai aktivitas fisik dengan analisis uji Pearson diperoleh p-value 0,000 < 0,05 dan nilai koefisien korelasi r pearson -0,505 yang ini menunjukkan bahwa adanya hubungan yang signifikan antara Indeks Massa Tubuh (IMT) dengan aktivitas fisik pada pasien aktif di Posyandu Puskesmas Tegalrejo, Kota Salatiga. Sedangkan nilai koefisien korelasi r pearson berkorelasi sedang, dan ditunjukkan dengan tanda negatif (-) yang berarti hubungan yang terjadi bersifat berlawanan arah. Sehingga semakin rendah aktifitas fisik maka semakin tinggi nilai IMT atau sebaliknya.Kata Kunci: aktivitas fisik, obesitas. AbstractObesity can be suffered by all age groups, as well as gender. Technological advances provide positive and negative effects. The positive impact of many activities becomes more practical and fast, while the negative impact of humans becomes increasingly lazy to move. Reduced physical activity results in the storage of energy stored in fat tissue, which causes obesity. The purpose of this study was to determine and analyze the relationship between physical activity and obesity at the Tegalrejo Health Center in Salatiga City, Central Java. This type of research is quantitative descriptive research. Respondents were active patients at the Tegalrejo Health Center Posyandu. The number of respondents was 59 people. The data obtained in this study are primary data and secondary data. Based on the correlation test of Body Mass Index (BMI) to the value of physical activity with Pearson test analysis obtained p-value of 0.000 <0.05 and Pearson correlation coefficient value of -0.505 which indicates that there is a significant relationship between Body Mass Index (BMI) and Physical activity in active patients at the Tegalrejo Health Center Posyandu, Salatiga City. While the value of the Pearson correlation coefficient is moderately correlated, and is indicated by a negative sign (-) which means that the relationship is in the opposite direction. So the lower the physical activity, the higher the BMI value or vice versa.Keywords: obesity, physical activity.
