Microalbuminuria, Kidney Function, and Daily Physical Activity
Baris Afsar
International Journal of Nephrology , 2013, DOI: 10.1155/2013/248416
Abstract: The present study was carried out to investigate independent relationship between daily physical activity, microalbuminuria, and kidney function. The demographic characteristics and laboratory parameters were recorded for all patients. The determination of daily activities was carried out by Nottingham Extended Activities of Daily Living Scale (NEADLS) which was performed for each patient in an interview. Totally 139 patients were enrolled. In the whole group NEADLS score was correlated with age (rho: ?0.759, ), clinical systolic blood pressure (rho: ?0.212, : 0.018), blood urea nitrogen (rho: ?0.516, ), creatinine (rho: ?0.501, ), uric acid (rho: ?0.308, ), albumin (rho: 0.382, ), total cholesterol (rho: ?0.194, : 0.022), LDL-cholesterol (rho: ?0.230, : 0.008), hemoglobin (rho: 0.256, : 0.002), creatinine clearance (rho: 0.565, ), 24-hour urinary protein excretion (rho: ?0.324, ), and 24-hour urinary albumin excretion (UAE) (rho: ?0.483, ). The multivariate linear regression of independent factors corelated with logarithmically converted NEADLS score (as a dependent variable) has shown that age ( ), presence of coronary artery disease ( : 0.011), hemoglobin ( : 0.020), 24-hour creatinine clearance ( : 0.004), and 24-hour urinary albumin excretion ( ) were independently corelated with NEADLS score. In conclusion, both UAE and kidney function were independently associated with daily physical activity. 1. Introduction Patients with chronic kidney disease (CKD) often have decreased physical fitness and activity [1]. The main causes are muscle atrophy [2], myopathy [3], inactivity [4], malnutrition [5], and lower albumin levels [6]. Besides, anemia, inflammation, and uremic acidosis also play a role [7]. It was well demonstrated that increased urinary protein and albumin excretion are well-known risk factors for cardiovascular end-organ damage [8, 9]. Emerging data suggest that greater physical activity may be associated with less albuminuria and physical activity could protect against albuminuria [10, 11]. However, the relationship between physical activity and albuminuria is not uniform. For example, in diabetic patients, physical activity is associated with lower albumin excretion, and physical activity has led to regression of albuminuria in interventional studies [12, 13]. However, in nondiabetics these associations were not observed [14, 15]. The relationship between physical activity and albumin/protein excretion become more complex by the phenomenon of postexercise proteinuria. Transient proteinuria, including albuminuria, is common after intense

Medical Journal of Bakirk?y , 2008,
Abstract: Objective: Ever since the introduction of peritoneal dialysis in the management of renal failure, complications related to technique, particularly peritonitis, have restricted its wider use and acceptance in continuous ambulatory peritoneal dialysis (CAPD) patients. In this study, we aimed to determine the frequency, most common causative agents and risk factors for peritonitis among our CAPD patients. Material and Methods: We included 132 CAPD patients (63 M, 69 F; age: 40.41±14.17 years, CAPD duration: 38.27±18.60 months) followed-up in our peritoneal dialysis center between January 1996-December 2003. Peritonitis was defined as the presence of organisms on gram stain or culture of peritoneal dialysis uid, leukocytes greater than 100 cells/mm3, neutrophil count >50% of the dialysate or symptoms of peritoneal in ammation. The patients were divided into three groups according to the number of peritonitis attacks; Group I= No attacks of peritonitis; Group II= 1 attack of peritonitis; Group III= ≥2 attacks of peritonitis. The patients in Group III were further evaluated for the presence of underlying risk factors for the development of peritoneal infection. Results: We observed no attacks in 74 patients, 1 attack in 42 patients and ≥2 attacks in 16 patients. Mean number of attacks was 2.31±0.47. The major causative microorganisms of peritonitis in our CAPD patients were Staphylococcus aureus and Staphylococcus epidermidis. The further evaluation of the patients with ≥2 attacks revealed that concomitant diabetes mellitus, secondary organ tuberculosis, and amyloidosis came forward as underlying risk factors for repeated peritonitis. Conclusions: Concomitant diabetes mellitus, secondary organ tuberculosis, and amyloidosis were risk factors in CAPD patients with repeated episodes of peritonitis. Our results emphasize that in patients with repeated attacks; patients’ risk factors must be carefully evaluated, (if possible) eliminated, and appropriately treated.

Journal of Geoscience and Environment Protection (GEP) , 2016, DOI: 10.4236/gep.2016.44008
Abstract: Flooding has been one of the recurring occurred natural disasters that induce detrimental impacts on humans, property and environment. Frequent floods is a severe issue and a complex natural phenomenon in Pakistan with respect to population affected, environmental degradations, and socio-economic and property damages. The Super Flood, which hit Sindh in 2010, has turned out to be a wakeup call and has underlined the overwhelming challenge of natural calamities, as 2010 flood and the preceding flood in 2011 caused a huge loss to life, property and land use. These floods resulted in disruption of power, telecommunication, and water utilities in many districts of Pakistan, including 22 districts of Sindh. These floods call for risk assessment and hazard mapping of Lower Indus Basin flowing in the Sindh Province as such areas were also inundated in 2010 flood, which were not flooded in the past in this manner. This primary focus of this paper is the use of Multi-criteria Evaluation (MCE) methods in integration with the Geographical Information System (GIS) for the analysis of areas prone to flood. This research demonstrated how GIS tools can be used to produce map of flood vulnerable areas using MCE techniques. Slope, Aspect, Curvature, Soil, and Distance from Drainage, Land use, Precipitation, Flow Direction, and Flow Accumulation are taken as the causative factors for flooding in Lower Indus Basin. Analytical Hierarchy Process-AHP was used for the calculation of weights of all these factors. Finally, a flood hazard Map of Lower Indus Basin was generated which delineates the flood prone areas in the Sindh province along Indus River Basin that could be inundated by potential flooding in future. It is aimed that flood hazard mapping and risk assessment using open source geographic information system can serve as a handy tool for the development of land-use strategies so as to decrease the impact from flooding.

Pakistan Journal of Biological Sciences , 2003,
Abstract: Phytosocio logical analysis carried out in 53 stands, created in habitat of wintering Houbara in Balochistan, suggests presence of at least 90 species, appearing in different combinations in 21 communities distributed under different conditions of soil, temperature and altitudes. The constancy of appearance of most of the species is low (> 20% only for Rhazya stricta, Anabasis sp., Pennisetum dichotomum, Calligonum comosum and Haloxylon ammodendron). There is a good degree of intra-stand homogeneity and most of the stands have < I I species. Shrubs constitute the only regular layer, herbs appearing during some part of the year and no regular tree layer. Vegetation appears in patches. Vegetative cover ranges between 0.87 and 34.17 % but generally it ranges between I and 15%. Most of the species are vigorous, reproducing sexually and/or a sexually and exhibit different degree of xerophytic characters. The phenological cycle exhibited by different species can be explained on temperature and precipitation pattern.
