RESUMO
Objective To investigate the correlation between admission hyperglycemia and clinical prognosis in elderly patients with community-acquired pneumonia.Methods Based on the electrical medical record (EMR),information of the patients with pneumonia was retrospectively collected and the necessary data were prepared and arranged.Based on clinical outcomes,demographic characteristics and clinical indicators were compared between groups in order to screen potential variables affecting clinical outcomes.Then,the random blood glucose level 8.6 mmol/L was considered to be the cutoff point for grouping patients,with clinical outcomes as outcome variables,random blood glucose levels as grouping variables,propensity score value analysis method was applied along with the ratio of 1:1 nearest neighbor matching method to generate paired samples in order to assess the impact of blood glucose level on mortality rate;With hospitalization time serving as time variable,survive analysis method was used to analyze COX proportional model.Results Five hundred and fifty-eight patients were enrolled in the analysis,197 patients of which were recorded dead during hospitalization (the dead group).After the correction of demographic characteristics,past medical history and blood test indexes,white blood cells,C reactive protein,random blood glucose at admission and triglyceride levels were regarded as potential factors for the deaths of patients (P<0.05).However,the propensity score analysis method suggested that there was no significant difference between the blood glucose levels and mortality.The survival analysis showed that the mortality in the high blood glucose group was higher than that in the normal blood glucose group (HR=1.68,95%CI(1.22,2.31)).Conclusion Admission hyperglycemia is an important indicator of adverse prognosis in elderly patients with pneumonia.It may be of significance for screening and identifying high-risk patients.
RESUMO
Objective To study the development characteristics of cavum sepit pellucidun (CSP)in prematures,neonates,infants and adults with MRI.Methods Brain MR images of different subjects including 141 prematures,106 neonates,171 infants and 35 046 adults were observed to determine the incidence and shape of CSP,and to measure its transverse diameter.Results CSP incidences were 100% (141/141)in prematures,97.17% (103/106)in neonates,2.26%(4/177)in infants and 0.82% (287/35 046)in adults respectively,and the CSP was cylinder (44.00%)or triangle in shape (56.00%)in prematures,triangle (76.40%)or fissure in shape (23.60%)in neonates.For infants or adults,each shape accounted for about a third of three kinds of shape respectively.Its mean transverse diameters were 5.7 mm in prematures,4.1 mm in neonates,13.3 mm in infants and 14.3 mm in adults respectivity.Conclusion CSP has different performances at development periods in human being brain.Most close after birth,while fewer remain in the whole life.
RESUMO
Objective Acrysof IQ Restor multifocal toric intraocular lens ( IOL) is a new product , which allows a single sur-gical procedure for presbyopia correction and corneal astigmatism management .This study was to evaluate the early clinical effects of phacoemulsification cataract surgery with implantation of a diffractive multifocal toric IOL . Methods We retrospectively analyzed 7 cases (9 eyes) of corneal astigmatism ≥1.0 diopter (D) treated by phacoemulsification with implantation of an Acrysof IQ Restor toric IOL.The patients were followed up for 3 months for observation of uncorrected distance visual acuity ( UDVA) , best corrected distance visual acuity ( CDVA) , uncorrected near visual acuity ( UNVA ) , best corrected near visual acuity ( CNVA ) , spherical equivalent (SE) refraction, focal depth, residual astigmatism, rotational stability of the IOL, contrast sensitivity (CS), and spectacle independ-ence preoperatively and at 1 week, 1 month, and 3 months after operation . Results At 3 months after surgery , the UDVA ( log-MAR), CDVA, UNVA, and CNVA were 0.07 ±0.10, 0.02 ±0.11, 0.12 ±0.06, and 0.08 ±0.07, respectively, with an SE re-fraction within ±0.50 D of the attempted spherical correction in 8 eyes (88.9%) and a focal depth of (5.32 ±1.78) D.The residual astigmatism at 3 months was significantly reduced as compared with the baseline ([0.25 ±0.28] vs [1.55 ±0.39] D, P0.05).At 3 months, the mean IOL axis rotation was (3.11 ±1.61)°and CS was remarkably im-proved ( P0.05) except at 18.0 cpd (P<0.05). Conclusion Implantation of the Acrysof IQ Restor multifocal toric IOL provides excellent overall quality of vision, spectacle independence, visual quality, and rotational stability for patients with cataract and corneal astigmatism.
