The present study examined how sunlight radiation, temperature and time in Yola climate can affect the physicochemical properties of drinking water in polyethylene terephthalate (PET) bottle in Yola Metropolis Nigeria. Conductivity, total dissolved solids (TDS), chemical oxygen demand (COD), pH, Cl-, and NO3 - were analyzed using standard methods for 42 days. Solvent extraction and GC-MS analysis were conducted periodically to monitor the appearance and identity of any migrant organic compounds. Sunlight exposure had the highest impact wherein conductivity, TDS, and COD trended upwards while pH decreased over time. However, Cl- and NO3- stayed constant. The GC-MS results showed the highest concentration of organic compounds in the sunlight exposed samples showing the molecular ion peak of benzene. Conversely, the negative control samples, stored in a cool dry place, showed no signs of leachates.

Abstract Background Effective patient-physician communication can improve patient understanding, agreement on treatment and adherence. This may, in turn, impact on clinical outcomes and patient quality of life (QoL). One way to improve communication is by using patient-reported outcome measures (PROMs). Heretofore, studies of the impact of using PROMs in clinical practice have mostly evaluated the use of standardized PROMs. However, there is reason to believe that individualized instruments may be more appropriate for this purpose. The aim of this study is to compare the effectiveness of the standardized QoL-instrument, the European Organization for Research and Treatment of Cancer Quality of Life C-30 (EORTC-QOL-C30) and the individualized QoL instrument, the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW), in clinical practice. Methods In a prospective, open-label, controlled intervention study at two hospital out-patient clinics, 390 patients with gastrointestinal cancer were randomly assigned either to complete the EORTC-QOL-C30 or the SEIQoL-DW immediately before the consultation, with their responses being shared with their physician. This was repeated in 3–5 consultations over a period of 4–6 months. The primary outcome measure was patients’ health-related QoL, as measured by FACIT-G. Patients’ satisfaction with the consultation and survival were secondary outcomes. Results There was no significant difference between the groups with regard to study outcomes. Neither intervention instrument resulted in any significant changes in health-related QoL, or in any of the secondary outcomes, over time. This may reflect either a genuine lack of effect or sub-optimization of the intervention. Since there was no comparison to standard care an effect in terms of lack of deterioration over time cannot be excluded. Conclusions Future studies should focus on the implementation process, including the training of physicians to use the instruments and their motivation for doing so. The effects of situational use of standardized or individualized instruments should also be explored. The effectiveness of the different approaches may depend on contextual factors including physician and patient preferences.

Abstract Health-related quality of life (HRQoL) is severely impaired in persons receiving dialysis. Malnutrition has been associated with some measures of poor HRQoL in cross-sectional analyses in dialysis populations, but no studies have assessed the impact of malnutrition and dietary intake on change in multiple measures of HRQoL over time. We investigated the most important determinants of poor HRQoL and the predictors of change in HRQoL over time using several measures of HRQoL. We enrolled 119 haemodialysis and 31 peritoneal dialysis patients in this prospective study. Nutritional assessments (Subjective Global Assessment [SGA], anthropometry and 24-hour dietary recalls) and HRQoL questionnaires (Short Form-36 [SF-36] mental [MCS] and physical component scores [PCS] and European QoL-5 Dimensions [EQ5D] health state [HSS] and visual analogue scores [VAS]) were performed at baseline, 6 and 12 months. Mean age was 64(14) years. Malnutrition was present in 37% of the population. At baseline, malnutrition assessed by SGA was the only factor independently (and negatively) associated with all four measures of HRQoL. No single factor was independently associated with decrease in all measures of HRQoL over 1 year. However, prevalence/development of malnutrition over one year was an independent predictor of 1-year decrease in EQ5D HSS and 1-year decrease in fat intake independently predicted the 1-year decline in SF-36 MCS and PCS, and EQ5D VAS. These findings strengthen the importance of monitoring for malnutrition and providing nutritional advice to all persons on dialysis. Future studies are needed to evaluate the impact of nutritional interventions on HRQoL and other long-term outcomes.

The Impact

As one of the 10 most polluted rivers in the world, Citarum river pollution has become the world’s spotlight. The pollution that occurred along the Citarum River in West Java has been the concern of the local government. Pollution not only comes from a plant and household, but also from industries. In this study the authors use descriptive quantitative method, where researchers will describe and compare the existing variables to see the possibilities that arise. Variable used is the number of industries that exist and how the impact against BOD. Biochemical Oxygen Demand (BOD) is a measuring instrument that is widely used to see the quality of oxygen levels in the water. In this paper shows that there is a possibility if BOD increases if the number of industries increases.

In order to research the groundwater quality of the Taikang Formation in Tertiary in west of Daqing Oilfield, resistivity logging data of 140 wells in the study area were analyzed to forecast the groundwater total dissolved solids (TDS) distribution of the plane. When the resistivity logging value (Rt) of the Taikang Formation in Tertiary is above 45Ω.m and its corresponding value of Formation water TDS is below 1000 mg/L, the quality of groundwater accords with life standards for drinking. The south area of Hongweixing well area and the east of Xishuiyuan well area, including Ranghulu, Qianjincun, Dulitun and Nanshuiyuan well area are favorable for high quality groundwater. The research provides the evidences to evaluate the groundwater quality in west Daqing Oilfield and determine specific well location, improving the efficiency of exploring the underground drinking water.

The Impact

The impact of partially treated wastewater on the water quality of Notwane river stretch in the Gaborone region of Botswana was investigated. Water samples collected at effluent discharge point and three other sampling sites downstream were analyzed for pH, temperature, Biological Oxygen Demand (BOD5), Ammonia-nitrogen (Ammonia-N) and Nitrate-nitrogen (Nitrate-N). Sampling was conducted bi-weekly between February 2013 and April 2013. The ranges of measured parameters were:  pH (7.6-8.5), temperature (22-23ºC), BOD5 (11.2-27.0 mg/l), Ammonia-N (2.4-60.5 mg/l), Nitrate-N (20.6-28.6 mg/l). Analysis of variance, Games-Howel multiple comparisons and Pearson correlation were used to separate variable means. The results signal river non-point pollution due to runoff inflow of organics mainly from land use and domestic waste dumping by nearby dwellings. Temperature, BOD5, and pH range values were all within the Botswana Bureau of Standards (BOBS) limit while the maximum Ammonia-N and Nitrate-N were above BOBS limit by 50.5 mg/l and 6.6 mg/l, respectively. Regulations on indiscriminate waste dumping and discharge standards adherence should be enforced.

© The Author(s) 2019. Community grandparenting may promote the well-being of older adults. We examined the impact of non-kin and grandparental childcare on quality of life and loneliness using longitudinal data from 2653 older New Zealanders collected over 2 years. Providing both non-kin and grandparental childcare predicted greater self-realisation for women only and was associated with reduced levels of control and autonomy for men. Non-kin childcare was also associated with reduced social loneliness over time independent of gender. Findings suggest that non-kin grandparenting has psychosocial benefits for older adults. Surrogate grandparenting offers promising avenues for those without grandchildren to experience the benefits of grandparenting.

The Impact

The indiscriminate disposal of industrial effluents and solid wastes in surface water bodies is detrimental to humans and aquatic organisms. Water quality monitoring is critical to identify pollutants of concern and develop effective management strategies. Hence, this study was conducted to assess the impact of waste disposal on the water quality of Aba Waterside River, Ogbor hill, Aba. Grab samples were collected upstream, midstream and downstream and some physicochemical and microbiological parameters were analyzed in accordance with standard methods for the analysis of water and wastewater. The results were compared with the Nigerian standard for drinking water quality and the national environmental effluent limitation regulations. Turbidity levels (10 -31mg/l) exceeded the maximum permissible levels for drinking water (5mg/l) and may be associated with higher levels of embedded disease-causing microbes and potentially harmful organic and inorganic substances. The biological oxygen demand midstream (1960mg/l) was remarkably high due to the effluent discharged from the abattoirs at that point. Fecal coliforms (3-198MPN/100ml) were detected in all samples, indicating the presence of other potentially harmful microorganisms. The findings of this study indicate that the water is unsuitable for direct drinking water purposes and stringent water quality control measures should be implemented.

<p>Groundwater is the main source of drinking water in the Nile Delta. Unfortunately, it might be polluted by seepage from polluted streams. This study was carried out to investigate the possible measures  to  protect groundwater  in the Nile delta aquifer using a numerical model (MT3DMS - Mass Transport 3-Dimension Multi-Species). The sources of groundwater contamination were identified and the total dissolved solids (TDS) was taken as an indicator for the contamination. Different strategies were investigated for mitigating the impact of polluted water: i) allocating polluted drains and canals in lower permeability layers; ii)  installing cut-off walls in the polluted drains, and finally, iii) using lining materials in polluted drains and canals. Results indicated these measures effective to mitigate the groundwater pollution. In particular, the cut-off wall was effective for contamination reduction in shallow aquifers, whereas it had no effect in the deep aquifer, while lining materials in polluted drains and canals were able to prevent contamination and to protect the freshwater in the aquifers.  It is worth mentioning that this study was partially supported by a bilateral project between ASRT (Egypt) and CNR (Italy).</p><p> </p><p> </p>
