Effect of Pfizer/BioNTech and Oxford/AstraZeneca vaccines against COVID-19 morbidity and mortality in real-world settings at countrywide vaccination campaign in Saudi Arabia

Mortality analyses of elderly patients with proximal femoral fracture during the pandemic: vaccination affects or not

PURPOSE

To evaluate the mortality rate, intensive care unit (ICU) referral, and Charlson comorbidity index (CCI) between different types of vaccinated and non-vaccinated patients operated on due to intertrochanteric femoral fracture (IFF) during the pandemic.

METHODS

Ninety-six patients (43 males, 53 females) who had proximal femur nails (PFN) for the IFF during the pandemic were included in the study. The patients were divided into four subgroups; non-vaccinated, and different types of vaccinated. Mortality rates, ICU referrals, and CCI relations were evaluated.

RESULTS

No significant difference was observed in terms of demographic data such as age, gender, side, CCI, and ICU referrals between the subgroups (p = 0.164, p = 0.546, p = 0.703, p = 0.771, p = 0.627 respectively). The mortality rate was significantly lower in the Sinovac + BioNTech subgroup (p = 0.044).

CONCLUSION

No relationship was found between mortality rate, ICU referral, and CCI in different types of vaccinated and non-vaccinated patient subgroups.

Ocular Complications Following Vaccination for COVID-19: A One-Year Retrospective

Vaccination efforts as a mitigation strategy in the corona virus disease 2019 (COVID-19) pandemic are fully underway. A vital component of understanding the optimal clinical use of these vaccines is a thorough investigation of adverse events following vaccination. To date, some limited reports and reviews have discussed ocular adverse events following COVID-19 vaccination, but a systematic review detailing these reports with manifestations and clinical courses as well as proposed mechanisms has yet to be published. This comprehensive review one-year into vaccination efforts against COVID-19 is meant to furnish sound understanding for ophthalmologists and primary care physicians based on the existing body of clinical data. We discuss manifestations categorized into one of the following: eyelid, orbit, uveitis, retina, vascular, neuro-ophthalmology, ocular motility disorders, and other.
