How Trace Element Levels of Public Drinking Water Affect Body Composition in Turkey.

Since waterborne minerals appear in ionic form and are readily absorbed by the gastrointestinal tract, drinking water could be a crucial source of mineral intake. However, no comprehensive research has yet determined how trace elements in drinking water relate to body composition. We aimed to assess the relationship between clinically important trace elements in public drinking water and body composition in average, overweight and obese individuals in Turkey. The study's population consisted of 423 participants: 143 overweight, 138 obese and 142 healthy control individuals, grouped according to clinical cutoff points of body mass index (BMI). We measured levels of lithium (Li), nickel (Ni), lead (Pb), silicon (Si), tin (Sn), strontium (Sr), boron (B), aluminium (Al), barium (Ba) and rubidium (Rb) in samples from wells of municipal water by using inductively coupled plasma mass spectrometry. We gauged all the participants' body composition measurements with a BC-418 body composition analyser. In all the participants, body weight values showed significant positive correlations with Ni levels in drinking water, as did BMI values with Al levels and percentage of obesity with Ni, Si and B levels. In particular, Ni levels showed significant positive correlations with the basal metabolic rate, activity calories, and total activity of participants. Giving findings showing correlations between obesity-related parameters and Al, Si, B and Ni content in drinking water, we hope that these associations will be clarified with further studies including cellular, experimental and clinical studies. Hence, medical practitioners must be aware of trace element levels in drinking water for overweight and obese patients.

Levels of anxiety and ways of coping of family members of patients hospitalized in the Neurosurgery Intensive Care Unit.

OBJECTIVE: To evaluate the levels of anxiety and ways of coping of family members of patients hospitalized in the Neurosurgery Intensive Care Unit (NICU). METHODS: The descriptive study was carried out with the families of 120 patients hospitalized in the NICU of a University Hospital in Turkey, between November 2005 and July 2006. Data were collected using a questionnaire for demographical information, The State and Trait Anxiety Inventory, and Ways of Coping Inventory. Statistical analysis of the data was carried out with SPSS software, using arithmetic mean and standard deviation, percentage, t test, Kruskall Wallis, Mann-Whitney U, and correlation analyses. RESULTS: Of the family members evaluated, 56.7% were males and the mean age of the family members was 34.7+/-11.13. The average score for the State Anxiety was 47.03+/-9.55, and Trait Anxiety was 44.11+/-7.62. Financial problems were the main source of anxiety, being experienced by 56.7% of the participants due to hospitalization of the patient in the intensive care unit. Submissive and helpless coping styles were observed more frequently, as the level of anxiety increased. CONCLUSION: In light of these findings, it has been found that members of the families of the patients hospitalized in the NICU experienced a significant amount of anxiety, and that they faced difficulties in coping with anxiety, indicating that they require help and support.
