Relationship between Renal Function and Bone Mineral Density in Postmenopausal Women.

Renal insufficiency is a risk factor for osteoporosis and can increase risk of fracture. It may be a result of an age-related decline in renal function or chronic kidney disease. In patients with CKD, accurate diagnosis of osteoporosis or CKD-MBD is important for determining the most appropriate treatment. This was a cross sectional study was done at Institute of nuclear medicine and Allied Sciences, BSMMU, Dhaka from 1st January 2014 to 31st December 2014. Study population was total 69 postmenopausal women age over 50 years. Women with Bilateral hip replacement or bilateral hip pins or screws, metallic rods in spine, Carrying out BMD scan within the week after other radiological investigation using contrast media e.g. Barium meals or enema, IVPs were excluded from study. Clinical variables were- age (years), height (cm), weight (kg), BMI. Laboratory variables were- serum creatinine and BMD (Dexa). Estimated GFR was determined by using the serum Creatinine by MDRD formula. Renal function test and Bone mineral density (BMD) were done in all of these patients. Majority (43.4%) of the patients were in 6th decade. The mean weight was found 57.4±11.2kg. Majority 41(59.4%) patients belonged to T score at hip (-1 to -2.5) and their mean T score at hip was found (-1.1±1.1). Osteopenia and osteoporosis were found in 59.4% and 4.3% respectively according to BMD. High serum creatinine level was found in 10.1% cases. Renal function impairment was found in 79.6% of patient. Majority (50.7%) patients had mild decrease of eGFR (60-89 ml/min/1.73m²), There was Pearson's correlation (r=0.156; p=0.200) but not significant was found between age with T score at hip of the patients. Positive Pearson's correlation (r=0.112; p=0.361) was found but not significant between age and serum creatinine level. A significant negative Pearson's correlation (r= -0.274; p=0.023) was found between T score at hip and serum creatinine level of the patients. A significant negative Spearman correlation (r=-0.278; p=0.021) was found between BMD and serum creatinine of the patients. A significant positive Spearman correlation (r=0.580; p=0.001) was found between BMD and estimated GFR of the patients. This study was undertaken to evaluate the relationship between renal function and bone mineral density in postmenopausal women. Majority of the postmenopausal women were in 6th decade and most of them were overweight and obese. Renal function impairment was found in 79.6% of patient. Osteoporosis was found in 04.3% and 20.3% cases according to T score at hip and T score at lumber spine respectively. Significant negative Pearson's correlation was found between T score at hip and serum creatinine level of the patients. Significant negative Spearman correlation was found between BMD and serum creatinine of the patients. Significant positive Spearman correlation was found between BMD and estimated GFR of the patients.

Neuropharmacological investigation, ultra-high performance liquid chromatography analysis, and in silico studies of Phyla nodiflora.

The increasing burden of neurological disorders is becoming a worldwide health challenge and researchers are continuously struggling to cure them by utilizing the miraculous medicinal properties of plants. The crude methanolic extract of whole herb of Phyla nodiflora (Pn.Cr) was subjected to phytochemical, antioxidant and neuropharmacological assessment. The Pn.Cr was initially exposed to the in vitro examination for phytocomposition through ultra-high performance liquid chromatography (UHPLC). The Sprague Dawley rats were chronically administered with various doses (100, 200 and 300 mg/kg) of Pn.Cr for one month with subsequent exposure to neurobehavioral and biochemical experimentation. The Pn.Cr exhibited a dose-dependent anxiolytic effect (P < 0.05 in comparison to control) as rats preferred central, illuminated and open arm zones in open field (OFT), light/dark (L/D) and elevated plus maze (EPM) tests. Likewise, scopolamine-induced amnesia was noticeably reversed with P < 0.05 by Pn.Cr as animals showed improved spontaneous alternation, discrimination index and shorter escape latencies in Y-maze, novel object recognition (NOR) and Morris water maze (MWM) tests. Subsequently, in vivo enzymatic assays depicted the reduced acetylcholinesterase and malondialdehyde levels. The levels of oxidative stress combating enzymes (glutathione peroxidase and superoxide dismutase) were increased in a dose-dependent style. The UHPLC detected 22 phytocompounds were further investigated in silico studied to predict the interaction of blood-brain barrier (BBB) crossing phytocompounds with human acetylcholinesterase. The four BBB crossing phytocompounds belonging to flavonoids, chalcones and alkaloids showed possible interaction with the target enzyme. We found that the phytocompounds owned by Pn.Cr might be playing multiple roles in modulation of different pathways to hinder the pathophysiology of neurological disorders including anxiety and Alzheimer's disease.
