Relationship between Disease Activity and Calcium Levels with Bone Mineral Density in Rheumatoid Arthritis Patients

Background: Arthritis rheumatoid (AR) is a chronic inflammatory disease that mainly affects the joints. Decreased bone mass and osteoporosis are its complications. Several factors such as dietary calcium, disease activity, physical activity, vitamin D levels, steroids can affect bone mineral density values. Aim: The purpose of this study was to determine the relationship between disease activity, calcium levels and bone mineral densitometry in patients with arthritis rheumatoid. Methods: 23 AR patients based on the 2010 ACR criteria including the inclusion criteria with a cross sectional study approach that had bone mineral densitometry (BMD) data for the last 1 year. Blood samples were also taken to check the total calcium level, the characteristics of the baseline data were collected, and the disease activity was examined using the DAS 28 LED. The relationship between these factors and the bone mass density was analyzed using the Spearman test. The analysis result was considered significant if p <0.05. Results: The results showed that the basic characteristics of the subjects were 45,87 years old, body mass index 24,51 kg / m2, duration of illness 3,96 years, steroid dose 3,48 mg, disease activity 4.35 (moderate disease activity), anti CCP 333,87 U / ml, rheumatoid factor (RF) 10,18 IU / ml, methotrexate 12,17 mg, leflunomide 20 mg. There was no significant relationship between serum calcium levels and disease activity with BMD. However, there was a significant relationship between age and BMI with BMD in the femur neck (p = 0,043), lumbar 3 (p = 0,017) and lumbar 4 (p = 0,048). Conclusion: There is no relationship between disease activity and calcium levels with bone mass density values in AR patients except for age and BMI

Pemanfaatan Resi Gudang Sebagai Opsi Optimalisasi Supply Chain Sebagai Alternatif Solusi Harga Panen Anjlok Pada Kelompok Tani

TSince long ago this agricultural country, Indonesia has never been separated from rice farming. However, the welfare of farmers has not been fully good. The harvest season that should bring joy and profit, not always absolute about the full benefits. Harvest season are often accompanied by problems such as drop of selling price due to abundant supply. The purpose of this study is to diclose that farmer groups can optimize the supply chain flow to overcome the drop of selling price. This research was conducted in descriptive research, by conducting direct observations on Tirta Jaya farmer groups in Demak, then mapping the existing supply chain flow, and finally finding optimization solutions in the flow. The results of this study indicate there is an unoptimal distribution channel for agricultural products, and the warehouse receipt system is the right alternative, and can be applied as one of the new distribution channels to overcome the drop of selling price during the harvest

Fluid pressures at hypocenters of moderate to large earthquakes

Many active faults are expected to develop fluid pressures in excess of hydrostatic pressures below 3 to 7 km depth during interseismic periods. Suprahydrostatic fluid pressures are known to reduce the stresses required for brittle failure. Stress differences that trigger moderate to large earthquakes typically range from 40 to 160 MPa, as indicated by earthquake shear stress drops and paleostress estimates obtained from mylonites. For stresses in this range (40–160 MPa), seismic fault reactivation requires in most cases pore fluid factors (fluid pressure/overburden pressure) higher than for hydrostatic fluid pressures (i.e., >0.37) along misoriented faults with fault angles ≥ 45°, such as many segments of the San Andreas fault system. For example, at a stress difference of 100 MPa and fault angles of 45° – 55°, fault reactivation at 7 to 20 km depth requires hypocentral pore fluid factors of ≈0.8-1 for reverse faults, 0.6–0.9 for strike-slip faults, and <0.8 for normal faults. Pore fluid factors increase with increasing cohesive strength of faults, increasing coefficient of internal friction, and increasing fault angle. Seismic reactivation of cohesive faults at stress differences of 40–160 MPa requires near the base of the seismogenic zone (≈15 km depth) suprahydrostatic fluid pressures at all possible fault angles. Pore fluid factors are ≈0.4–0.9 for normal faults, ≈0.6-1 for strike-slip faults, and ≈0.8–1.05 for thrust or reverse faults. These constraints are potentially useful for the modelling of seismic faulting and earthquake recurrence times
