The immune system protects us by producing antibodies against viruses and diseases. Currently,  there is no cure in treating patients infected with COVID-19.  Even though many nations declared extrapolate findings on the COVID-19 vaccine trial, this will require months to develop an effective vaccine successfully. Meanwhile, an immune-enhancing preventive approach can be considered in order to strengthen the immune system that would enhance the host's resistance to infection. Although the leading health authorities of national and international health institutions, the Centers for Disease Control and Prevention (CDCP), and the World Health Organization (WHO) consistently providing standard guidelines focusing on treatment, prevention, and promotion perspectives, this article discussed the promising alternative prophylactic solutions in enhancing host immunity with a highly valuable supplements Zinc, Vitamin D to protect human beings from COVID-19 pandemic disease.

Stroke is a severe health condition that causes morbidity and death all over the world, and nurses have a significant role in the care of patients admitted with stroke. The study aimed to explore knowledge and perception of stroke among nursing students to provide high quality of care. A descriptive, quantitative study was conducted among 192 participants between May 2018 and January 2019. The study included female students, aged 18 and older. The Self- structured questionnaire was used for data collection, composed of socio-demographic and stroke related-knowledge.. The Pilot study was carried out among 10% of volunteers. Descriptive and inferential statistics were conducted using a computer software program (SPSS) version 20. The T-test and chi-squared tests were used with a P-value of 0.05 to ensure the significances of the results. The study was approved by the Institutional Review Board at the college of nursing, and written consent was taken from all participants. More than 90% of participants were single and knew what a stroke was, and more than 50% knew the different types of stroke. Also, participants had moderate knowledge about risk factors, signs, symptoms, and stroke prevention with 45.3%, 47.4%, and 38.0% respectively, and (50.0%) had poor knowledge of post-stroke complications and medications for treatment. Education level had a positive effect on participants’ knowledge, most of the participants in at the fourth class had a moderate level of knowledge about risk factors for stroke, which was statistically significant (p-value was is 0.037), while third and fourth class students had a moderate level of knowledge about’ signs and symptoms of stroke, which was statistically not significant (p-value > 0.005). Overall, students had a moderate knowledge score of stroke perception. Education level has a positive effect on fourth-year students' knowledge compared with students from third and second year classes.

Aims: The study was conducted to assess the risk factors leading to the development of obesity among female students to adopt strategies to combat this problem and decrease the risk.  Methodology A cross-sectional study method was conducted among 129 participants at the University in 2017. Stratified proportional random sampling was taken. The electronic questionnaire and body mass index (BMI) observational checklist were used for consented participants who agreed to participate in the study Results: Descriptive statistics, the Chi-Square, and T-test were used. The studied subject’s ages range from 18> to 25yers, most of them were single (93%), and their economic status was moderate. Most of the participants consumed unhealthy diets rich in carbohydrates, and fat. Also, more than 60 % of participants consumed low vegetables and fruits. Chi squire showed insignificantly overweight among low fruit consumers while the obesity among moderate fruit consumers (p-value 0.813). Conclusion: This study explored the occurrence of both overweight and obesity were strongly associated with risky lifestyles for participants.

Aims: The aims of the study to estimate the prevalence of obesity and overweight among females’ students to adopt strategies to combat these problems and decrease their risk. Study design: A cross-sectional study design. Methodology: It was conducted among 129 participants at Um Al-Qura University collage of nursing, 2017. Stratified proportional random sampling was adopted, structured questionnaire and checklist for body height and weight were used to collect data. Agreement from each participant was taken and then written consent was obtained. The data was analyzed used SPSS version 20. A descriptive statistic was done, BMI was calculated to estimate the prevalence and Chi Square test for statistically significant was used. Results: Shown that the prevalence of overweight and obesity were 9.0% for each and insignificant (P=Value 0.266) similar among age groups. The study included 129 females, 51% at age group of 22-25 years and 88% with moderate family income. Also, a high significant obesity 10%, was found among single, while overweight was a high among married participants 45% (P value= 0.002). Addition to high insignificant obesity associated with high family income (P value=0.450). Conclusions: The study explored that the prevalence of both overweight and obesity were high and similar among participants age groups, and strongly associated with many risk factors which should be considering a serious health problem that need specific attention from the community and health sectors.
