ABSTRACT
Background Hepatitis C, a highly contagious viral infection transmitted through blood-to-blood contact, poses a significant threat to public health owing to its potential to induce extensive liver damage, leading to the development of life-threatening conditions such as liver cirrhosis and hepatocellular carcinoma, commonly known as liver cancer. Objective This cross-sectional study aims to assess the level of awareness of hepatitis C among the general population in Riyadh, Saudi Arabia. Methodology The study was conducted in Riyadh, Saudi Arabia. A national cross-sectional survey was conducted using a predesigned self-administered validated electronic questionnaire. The questionnaire was distributed electronically to the general population from April to September 2023. Results Out of the 800 participants, most were females (472, 59%), and the largest age group was between 23 and 29 years old (305, 38.1%). Saudi Arabians constituted the highest proportion of participants (609, 76.1%), and most participants were single (437, 54.6%). In terms of occupational status, 288 (36%) worked in occupations not listed. The study found that 463 (57.9%) participants had a low level of awareness about the global prevalence of hepatitis C. Additionally, 489 (61.1%) were aware that hepatitis C can cause both acute and chronic hepatitis, and 441 (55.1%) knew that most infected patients may develop chronic hepatitis. A majority (484, 60.5%) were aware of the importance of washing with soap and water after an accidental needle stick injury. Most participants (574, 71.8%) were aware of the common modes of hepatitis C transmission, such as unsterilized instruments, needle stick injuries, and sharing contaminated needles during drug use. Furthermore, 548 (73%) were aware of the transmission risk through unscreened blood transfusion, and 561 (70.1%) were aware of the higher risk of infection for individuals with multiple sexual partners. Conclusion The study highlights a low level of awareness among participants regarding the treatment and prevention of hepatitis C. To address the low level of awareness regarding the treatment and prevention of hepatitis C, targeted strategies and interventions are needed. This includes the development and implementation of public awareness campaigns, creation of informative educational materials, specialized training programs for healthcare professionals, establishment of support groups and counseling services for individuals living with hepatitis C, and continued support for research efforts and knowledge dissemination. By increasing awareness about hepatitis C, its treatment, and prevention, we can improve outcomes for individuals affected by the disease and reduce its overall burden on communities.
ABSTRACT
Polymeric poly (lactic-co-glycolic acid) (PLGA)-lipid hybrid nanoparticles (PNPs)-based therapy are powerful carriers for various therapeutic agents. This study was conducted to evaluate the chemotherapeutic potential of free 5-flurouracil (5FU) and synthetized 5FU-PNPs and impact on p53-dependent apoptosis in mammary carcinomas (MCs) grown in mice. Breast cancer cells were injected in Swiss albino female mice and 2 bilateral masses of MC were confirmed after one week. Mice were distributed to five experimental groups; Group 1: MC control group. Groups 2 and 3: MC + free 5FU [5 or 10 mg per kg] groups. Groups 4 and 5: synthetized MC+ 5FU-PNPs [5 or 10 mg per kg] groups. Medications were administered orally, twice weekly for 3 weeks. Then, tumors were dissected, and sections were stained with hematoxylin-eosin (HE) while the other MC was used for measuring of cell death and inflammatory markers. Treatment with 5FU-PNPs suppressed the MC masses and pathologic scores based on HE-staining. Similarly, greater proapoptotic activity was recorded in 5FU-PNPs groups compared to free 5FU groups as shown by significant upregulation in tumoral p53 immunostaining. The current results encourage the utility of PNPs for improving the antitumor effect of 5FU. The chemotherapeutic potential was mediated through enhancement of tumoral p53-mediated p53 up-regulated modulator of apoptosis (PUMA) genes. Additional studies are warranted for testing the antitumor activity of this preparation in other mouse models of breast cancer.
ABSTRACT
Wernicke's encephalopathy (WE) is an acute neuropsychiatric emergency due to thiamine deficiency. This report includes a case of a young pregnant female in her second trimester (17th weeks) complaining of hyperemesis gravidarum, who, due to excessive vomiting, developed severe vitamin B1 deficiency, leading to WE and Korsakoff's psychosis. The typical triad of confusion, ocular signs, and ataxia is fundamental for the diagnosis of WE, yet not all cases present with the entire triad; however, our patient presented with all the symptoms. Replacement of thiamine, which is a crucial vitamin that plays an important role in the integrity of the nervous system, is the first step in the management of WE.
ABSTRACT
Background Sudden infant death syndrome (SIDS) refers to the unexpected and unexplained death of a child under one year old. The pathogenesis of SIDS remains unclear. However, certain factors such as the child's sleeping position, sleeping on a soft mattress, and maternal smoking have been suggested to contribute to its occurrence. The objective of this study was to evaluate the level of awareness of SIDS among Saudi Arabian women in 2023. Methodology A cross-sectional study was conducted among 300 mothers in Saudi Arabia, over a period of three months, from June to August 2023, using an online questionnaire to gather socio-demographic information from mothers of infants younger than one year old in Saudi Arabia, the sleeping practices of their infants, and their knowledge about SIDS risk factors. Data were coded using the Statistical Package for Social Sciences (SPSS) (IBM SPSS Statistics, Armonk, NY), and statistical significance tests were employed for data analysis. A p-value of <0.05 was considered significant. Results Among the 277 participating mothers, 44% were 31-40 years old, 93% were Saudi, 60% were employed, 65% were nonsmokers, and 64% placed babies in a supine position for sleep. About 37% of mothers used a duvet for bedding during summer, compared to 66% who used a duvet during winter, and 81% utilized a soft mattress cover in their children's beds. Additionally, 67% of mothers reported that their children used a pacifier while sleeping. More than half (54%) of mothers were aware of SIDS with media as their primary source of information. Among those under 21 years old, 50% demonstrated a high level of awareness, compared to 36% of those aged over 50. Conclusion Most women in this study were found to be unaware of SIDS. Among those who were aware, the media was the primary source of information. Higher educational attainment was associated with better understanding.
