This study seeks to find out if chronic exposure via drinking water to high doses of a mixture of metals found as contaminants in tap and bottled water sources can alter the systemic physiology of residents.

A case control study was designed, 18 subjects drinking mainly tap water as main group (group I) and 15 subjects drinking exclusively bottled water as control group (group II) for a minimum of two years. Cadmium, lead, chromium and iron concentrations in drinking tap and bottled water samples were measured. The effect potential of the same metals were evaluated by assessing liver and kidney functions and haemoglobin levels for the studied subjects.

Iron concentration was found to be significantly higher in drinking tap water samples compared to bottled. Chromium, lead and iron were significantly higher in blood samples of group I subjects compared to the control group. Blood creatinine levels were positively correlated with that of chromium and cadmium of group I; and chromium levels of group II. Urea levels was positively correlated with lead levels of group I. Haemoglobin was positively correlated with iron blood levels of group I and negatively with lead levels of group II. No appreciable changes were found in the blood clinical markers of the liver functions of either group.

This study gives a concise idea about the higher level of some heavy metals in tap water compared to bottled and how heavy metal contaminants in drinking water may affect kidney function and haemoglobin level of consumers.

The purpose of this paper is to identify the extent of actual malnutrition and its risk among cancer patients receiving radiotherapy and/or chemotherapy in the Libyan city of Benghazi.

A cross‐sectional nutritional assessment study using the patient‐generated subjective global assessment (PG‐SGA) was carried out on 200 (91 males and 109 females) cancer patients undergoing chemotherapy and/or radiotherapy.

A total of 25 per cent of the subjects were severely malnourished while 73.5 per cent were either at risk of malnutrition or suspected to be malnourished. Almost all (99.5 per cent) needed some degree of intervention (critical in nature for 83.5 per cent). Family income and physical activity were associated with nutritional status (p<0.05). Body Mass Index alone is an insensitive criterion for identifying malnutrition among such patients. All the sections and subsections of the PG‐SGA had a statistically significant positively correlation with its total score (r=0.51‐0.96, p<0.05). Dieticians played a very limited role in patient nutritional care.

It is suggested that dieticians should play a more participatory and prominent role in a multidisciplinary team involved in patient nutritional care. The PG‐SGA can help identify areas where tailor made strategies to counteract specific malnutrition or its risk can be planned, implemented and monitored.

There exists a considerable prevalence of malnutrition among Benghazi cancer patients undergoing chemotherapy and/or radiotherapy, most of whom need critical intervention.

The level of mental alertness among students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University. The level of self-competence of female students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University. To learn about the relationship between mental alertness and self-competence among students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University.

The researchers used the experimental method by following the experimental design with two measurements, tribal and posterior, for two groups, one experimental and the other control, due to its suitability to the nature of this research. Research sample: the research community included female students stumbling in the scientific path of Rayyan, the second semester of the academic year 2020–2021 AD, where the researchers selected the research sample in a deliberate manner from the stalled students of 25 students and a random sample of 10 female students was withdrawn to conduct the exploratory study. The number of the basic research sample is 15 female students. Reasons for selecting the search sample: all of the sample members are female students stumbling in the scientific path of Al-Rayyan for the academic year 2020–2021 and all sample members agree to apply the research.

The researchers refer to this to the virtual psychological guidance program-specific objectives, as well as the follow-up of the scientific principles and principles and the legalization of the measurement tools used in the research and the diversity of the program within the parts of the program and the training sought to develop the ability to manage pressures and emotions and training in social skills, awareness and self-awareness and the use of exercises relaxation, breathing and modern self-help, as well as the use of different methods and techniques such as the method of dialogue, discussion, awareness of feelings and problem-solving, which led to a change in behavior and personal characteristics, which led to a change in behavior and personal characteristics, leading to the development of behavior and personal characteristics.

The study aims to design a hypothetical psychological counseling program as a method of health care and its effect on the level of mental alertness and the level of self-efficacy of students who have struggled to study at the Deanship of the preparatory year – Imam Abdul Rahman bin Faisal University. The researchers used the experimental approach and applied this study on a sample of 25 students from the students who failed to study at the Deanship of the preparatory year for the second semester of the academic year 2020–2021 AD and the most important results were that the psychological counseling program as a method of health care had a positive effect on improving the level of mental alertness and the level of self-efficacy among the students who had failed to study. There is a positive correlation between the level of mental alertness and self-efficacy of struggling students as a way of health care.
