Surgical site infections are among the most prevalent and costly healthcare-associated infections, resulting in poor patient outcomes and even death. Cefazolin is a first-generation cephalosporin antibiotic that is widely used for surgical prophylaxis in a variety of surgical disciplines. Although previous studies showed that cefazolin is effective in preventing surgical site infections, other agents, such as cefuroxime and ceftriaxone, were used excessively for surgical patients. The present analysis included only clinical trials comparing the efficacy of cefazolin to cefuroxime, ceftriaxone, and cefamandole in lowering SSIs using PubMed, Google Scholar, and ClinicalTrials.gov. Review Manager software (RevMan version 5.4) was used to conduct the meta-analyses. A total of 12,446 patients were included in the study. Among these patients, 6327 patients received cefazolin and 6119 patients received cefamandole, cefuroxime, or ceftriaxone. Our analysis showed that cefazolin is as effective as cefuroxime, cefamandole, and ceftriaxone in preventing surgical site infections. Hence, our findings have provided evidence for the use of cefazolin before surgeries because of its efficacy, as previous studies showed that it is inexpensive and safer than other agents.

Gentamicin causes kidney injury due to its accumulation in proximal tubule epithelial cells via the megalin/cubilin/CLC-5 complex. Recently, shikonin has been shown to have potential anti-inflammatory, antioxidant, antimicrobial, and chloride channel-inhibiting effects. The current study investigated the alleviation of gentamicin-induced renal injury by shikonin while preserving its bactericidal effect. Nine-week-old Wistar rats were administered 6.25, 12.5, and 25 mg/kg/day shikonin orally, one hour after the i.p. injection of 100 mg/kg/day gentamicin for seven days. Shikonin significantly and dose-dependently alleviated gentamicin-induced renal injury, as revealed by restoring normal kidney function and histological architecture. Furthermore, shikonin restored renal endocytic function, as indicated by suppressing the elevated renal megalin, cubilin, and CLC-5 and enhancing the reduced NHE3 levels and mRNA expressions induced by gentamicin. These potentials could be attributed to the modulation of the renal SIRT1/Nrf2/HO-1, TLR-4/NF-κB/MAPK, and PI3K/Akt cascades, which enhanced the renal antioxidant system and suppressed renal inflammation and apoptosis, as indicated by enhancements of SIRT1, Nrf2, HO-1, GSH, SOD, TAC, Iκb-α, Bcl-2, PI3K, and Akt levels and mRNA expressions, with reduction of TLR-4, NF-κB, MAPK, IL-1β, TNF-α, MDA, iNOS, NO, cytochrome c, caspase-3, Bax levels, and Bax/Bcl-2 ratio. Therefore, shikonin is a promising therapeutic agent for alleviating gentamicin-induced renal injury.

Telepharmacy is a technology-based service that provides promoted services such as counseling, medication administration and compounding, drug therapy monitoring, and prescription review. It is unclear whether hospital pharmacists possess the necessary knowledge, attitudes, and willingness to practice telepharmacy. The current study sought to investigate Saudi Arabian hospital pharmacists’ understanding, attitudes, and level of preparedness for telepharmacy services. A total of 411 pharmacists responded to the survey. Only 43.33% of the respondents agreed that telepharmacy is available in Saudi Arabia and 36.67% of the respondents agreed that patients in rural areas can have more medication access and information via telepharmacy. Only 29.33% of pharmacists agreed that telepharmacy improves patient medication adherence, and about 34.00% of the pharmacists agreed that telepharmacy saves patients money and time by eliminating the need for them to travel to healthcare facilities. This research found that hospital pharmacists were unsure of their level of knowledge, their attitude toward telepharmacy, and their willingness to incorporate it into their future pharmacy practices. To ensure that tomorrow’s pharmacists have the skills they need to provide telepharmacy services, telepharmacy practice models must be incorporated into the educational programs that prepare them.

Background: Angiotensin receptor-neprilysin inhibitor (ARNI) prescription in the United States remains suboptimal despite strong evidence for efficacy and value in heart failure with reduced ejection fraction. Factors responsible for under prescription are not completely understood. Economic limitations may play a disproportionate role in reduced access for some patients. Methods: This is an analysis of the Get With The Guidelines-Heart Failure registry, supplemented with data from the Distressed Community Index. Data were fit to a mixed-effects regression model to investigate clinical and socioeconomic factors associated with ARNI prescription at hospital discharge. Missing data were handled by multilevel multiple imputation. Results: Of the 136 144 patients included in analysis, 12.6% were prescribed an ARNI at discharge. The dominant determinants of ARNI prescription were ARNI use while inpatient (odds ratio [OR], 72 [95% CI, 58–89]; P <0.001) and taking an ARNI before hospitalization (OR 9 [95% CI, 7–13]; P <0.001). Having an ACE (angiotensin-converting enzyme) inhibitor/angiotensin receptor blocker (ARB)/ARNI contraindication was associated with lower likelihood of ARNI prescription at discharge (OR, 0.11 [95% CI, 0.10–0.12]; P <0.001). Socioeconomic factors associated with lower likelihood of ARNI prescription included having no insurance (OR, 0.60 [95% CI, 0.50–0.72]; P <0.001) and living in a ZIP Code identified as distressed (OR, 0.81 [95% CI, 0.70–0.93]; P =0.010). The rate of ARNI prescription is increasing with time (OR, 2 [95% CI, 1.8–2.3]; P <0.001 for patients discharged in 2020 as opposed to 2017), but the disparity in prescription rates between distressed and prosperous communities appears to be increasing. Conclusions: Multiple medical and socioeconomic factors contribute to low rates of ARNI prescription at hospital discharge. Potential targets for improving ARNI prescription rates include initiating ARNIs during hospitalization and aggressively addressing patients’ access barriers with the support of inpatient social services and pharmacists.

The uncertainty about COVID-19 outcomes in angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) users continues with contradictory findings. This study aimed to determine the effect of ACEI/ARB use in patients with severe COVID-19. This retrospective cohort study was done in two Saudi public specialty hospitals designated as COVID-19 referral facilities. We included 354 patients with a confirmed diagnosis of COVID-19 between April and June 2020, of which 146 were ACEI/ARB users and 208 were non-ACEI/ARB users. Controlling for confounders, we conducted multivariate logistic regression and sensitivity analyses using propensity score matching (PSM) and Inverse propensity score weighting (IPSW) for high-risk patient subsets. Compared to non-ACEI/ARB users, ACEI/ARB users had an eight-fold higher risk of developing critical or severe COVID-19 (OR = 8.25, 95%CI = 3.32–20.53); a nearly 7-fold higher risk of intensive care unit (ICU) admission (OR = 6.76, 95%CI = 2.88–15.89) and a nearly 5-fold higher risk of requiring noninvasive ventilation (OR = 4.77,95%CI = 2.15–10.55). Patients with diabetes, hypertension, and/or renal disease had a five-fold higher risk of severe COVID-19 disease (OR = 5.40,95%CI = 2.0−14.54]. These results were confirmed in the PSM and IPSW analyses. In general, but especially among patients with hypertension, diabetes, and/or renal disease, ACEI/ARB use is associated with a significantly higher risk of severe or critical COVID-19 disease, and ICU care.
