We aimed to find the most useful biomarker by examining the prognostic effect of neutrophil‐lymphocyte ratio (NLR), lymphocyte‐monocyte ratio (LMR), platelet‐lymphocyte ratio (PLR), and lymphocyte‐C reactive protein ratio (LCR) in patients with coronavirus disease 2019 (COVID‐19). Three hundred and four patients diagnosed with COVID‐19 infection in our hospital within 5 months (April–August 2020) were examined. Laboratory values and demographic findings of the patients were analyzed retrospectively. Thirty‐six patients were diagnosed with severe cases. The ratio of NLR, LMR, PLR, and LCR of patients with severe and those with nonsevere clinical symptoms were statistically analyzed. The NLR and PLR ratios of those with severe clinical symptoms were significantly higher (
p
< 0.001), the LCR rate was significantly lower (
p
< 0.001), and there was no significant difference in the LMR rate (
p
= 0.199). When we examined other peripheral blood parameters, we found that CRP was high, lymphocyte and monocyte were low (
p
< 0.001), but neutrophil (
p
= 0.416) and platelet (
p
= 0.998) were not statistically different between the groups. According to the results, routine blood values are abnormal in patients with COVID‐19. NLR, PLR, and LCR ratios can be used as more significant biomarkers than other values in predicting the prognosis of patients.
The authors aim to determine the periorbital soft tissue anthropometric norms for Turkish young adults for right and left eyes using a noninvasive two-dimensional photogrammetric analysis. Anthropometric measurements of the periorbital soft tissue were taken from 172 female and 56 male Turkish adults aged between 18 and 24 years. The periorbital soft tissue profiles (ocular and palpebral) for males and females were digitally analyzed using linear measurements made with standardized photographic records, taken in a natural head position. Statistically significant differences were found for ocular soft tissue measurements according to gender except inner intercanthal distance (P = 0.125) and right horizontal palpebral aperture (P = 0.240). Statistically significant differences were found for palpebral soft tissue measurements according to gender except right pretarsal skin height (P = 0.112) and left pretarsal skin height (P = 0.056). Results were compared with other ethnic groups. Normal periorbital soft tissue measurements are fundamental anatomical parameters utilized in ophthalmology, optometry, ophthalmic industry, oculoplastic surgery, clinical genetics, dermatocosmetology. Further, normal anthropometric measurements generate reference data for studies in craniofacial dysmorphology, oculoplastic surgery, dermatocosmetology, and comparative physical anthropology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
