Emergence of High Antimicrobial Resistance among Critically Ill Patients with Hospital-Acquired Infections in a Tertiary Care Hospital.

Background and Objectives: Inappropriate antibiotic usage in hospitalized patients contributes to microbial resistance. Our study aimed to examine the incidence of clinical bacterial isolates and their antibiotic resistance burden among critically ill patients in different hospital units. Materials and Methods: A single-centered cross-sectional study was conducted in a 120-bed tertiary care hospital that included 221 critically ill patients with hospital-acquired infections. Bacterial cultures and sensitivity reports were obtained and followed by a formal analysis of the antibiogram results to explore recovered isolates' prevalence and antibiotic susceptibility patterns. Results: Gram-negative bacteria were the most predominant pathogens among recovered isolates from the various hospital units (71%). Klebsiella sp. was the most prevalent microbe, followed by Acinetobacter sp., with an incidence level of 28% and 16.2%, respectively. Among the Gram-positive organisms, the coagulase-negative Staphylococci were the most predominant organism (11.3%), while (6.3%) methicillin-resistant Staphylococcus aureus (MRSA) isolates were recovered from different hospital units. Antibiotic sensitivity testing showed that polymyxin B was the most effective antibiotic against Gram-negative bacteria, whereas vancomycin and linezolid were the most active antibiotics against Gram-positive pathogens. Moreover, 7% of the Gram-negative bacteria isolated from different units showed positive production of extended-spectrum beta-lactamase (ESBL). Conclusions: The current study describes the high antibiotic resistance patterns in various hospital units that need extra legislation to prevent healthcare providers from misprescription and overuse of antibiotics.

Evidence for the Efficacy of a High Dose of Vitamin D on the Hyperinflammation State in Moderate-to-Severe COVID-19 Patients: A Randomized Clinical Trial.

Background and Objectives: Vitamin D supplementation plays a key effect in lowering cytokine storms among COVID-19 patients by influencing the activity of the renin-angiotensin system and the production of the angiotensin-2 converting enzyme. The study was conducted to explore the effect of high-dose intramuscular vitamin D in hospitalized adults infected with moderate-to-severe SARS-CoV-2 in comparison with the standard of care in the COVID-19 protocol. Materials and Methods: Two groups of patients were compared in this prospective randomized controlled trial as the vitamin D was administered orally to group 1 (alfacalcidol 1 mcg/day) and intramuscularly to group 2 (cholecalciferol 200,000 IU). One hundred and sixteen participants were recruited in total, with fifty-eight patients in each group. Following the Egyptian Ministry of Health's policy for COVID-19 management, all patients received the same treatment for a minimum of five days. Results: A significant difference was recorded in the length of hospital stay (8.6 versus 6.8 days), need for high oxygen or non-invasive mechanical ventilator (67% versus 33%), need for a mechanical ventilator (25% versus 75%), clinical improvement (45% versus 55%), the occurrence of sepsis (35% versus 65%), and in the monitored laboratory parameters in favor of high-dose vitamin D. Moreover, clinical improvement was significantly associated with the need for low/high oxygen, an invasive/non-invasive mechanical ventilator (MV/NIMV), and diabetes, while mortality was associated with the need for MV, ICU admission, atrial fibrillation, chronic obstructive pulmonary disease, asthma, and the occurrence of secondary infection. Conclusions: Our study showed that high-dose vitamin D was considered a promising treatment in the suppression of cytokine storms among COVID-19 patients and was associated with better clinical improvement and fewer adverse outcomes compared to low-dose vitamin D.

Assessment of Oral Health-Related Quality of Life and Its Associated Factors among the Young Adults of Saudi Arabia: A Multicenter Study.

Oral health-related quality of life (OHRQoL) is an essential indicator of people's overall health and health-related quality of life. Poor oral health and OHRQoL among young adults lead to numerous negative consequences and an increased burden on the healthcare system. The present study is aimed at assessing the OHRQoL among the young adults of Saudi Arabia, identifying self-rated oral health, and determining the relationship between sociodemographic and lifestyle factors with the OHRQoL. The present analytical cross-sectional survey was conducted among 1152 health and non-health-related college university students from three randomly selected universities. The OHRQoL was evaluated using the validated Arabic version of the oral health impact profile-14 questionnaire (OHIP-14). Of the population studied, one-fourth of the participants (24.9%) reported poor or fair oral health, and the highest OHIP-14 score was found in the domains of physical pain (4.14), followed by psychological discomfort (4.07). Logistic regression analysis revealed that the poor oral health category was significantly associated with male gender (ref: female: adjusted OR (AOR) = 1.89, 95%CI = 1.23-2.94, p = 0.004), daily smokers (ref: nonsmokers: AOR = 3.47, 95%CI = 1.97-4.82, p < 0.001), chocolate and candies intake more than once a day (ref: never; AOR = 1.54, 95%CI = 1.10-2.19, p = 0.034), and did not seek periodical dental care (ref: periodic dental care received: AOR = 2.23, 95%CI = 1.53-2.86, p = 0.002). The present study revealed the factors associated with poor OHRQoL. The concerned authorities should consider the implementation of periodic dental checkups for university students, especially for the high-risk group. Furthermore, it is recommended to have regular health education programs that will help to change the student's lifestyle and poor oral health behaviors.
