A multicentre, open, investigator-initiated phase IV clinical trial to evaluate the efficacy and safety of ingenol mebutate gel, 0·015% on the face and scalp, and 0·05% on the trunk and extremities, in Korean patients with actinic keratosis (PERFECT).

BACKGROUND: Ingenol mebutate gel is a novel, field-directed topical treatment for actinic keratosis (AK). Most pivotal studies have targeted Western populations. No clinical study has been conducted to investigate its efficacy and safety in Asian populations. OBJECTIVES: To evaluate the efficacy and safety of ingenol mebutate gel for treating AK of face/scalp and trunk/extremities in a large Asian (Korean) population. PATIENTS AND METHODS: In this multicentre, open-label, interventional, parallel-group, prospective phase IV study (PERFECT, trial registration no.: NCT02716714), the eligible patients were allocated into either the face/scalp or the trunk/extremities group, according to their selected treatment area location. After application of ingenol mebutate gel, the participants were followed up for 6 months. The primary efficacy endpoint was complete clearance (CC) of AK lesions in the selected treatment area at day 57. Quality of life was evaluated using Skindex-29. Safety endpoints included local skin responses, scar, pigmentation, pain and adverse events. RESULTS: In total, 78·1% [95% confidence interval (CI) 66·86-86·92%] of subjects had CC at day 57, with 76·6% (95% CI 64·31-86·25%) in the face/scalp group and 88·9% (95% CI 51·75-99·72%) in the trunk/extremities group. Among them, CC was sustained in 88·9% (48 of 54, 95% CI 77·37-95·81%) at month 6. The local skin responses significantly increased 1 day after the treatment compared with baseline, and decreased afterwards. Among the total subjects, 7·8% (6 of 77) had hyperpigmentation on the application area. Scars were not reported. CONCLUSIONS: Ingenol mebutate is effective for the treatment of AK in Asians, with tolerable safety profiles.

Effect of the sexual abstinence period recommended by the World Health Organization on clinical outcomes of fresh embryo transfer cycles with normal ovarian response after intracytoplasmic sperm injection.

This study was to investigate whether the sexual abstinence period (SAP) recommended by the World Health Organization (WHO) affects clinical outcomes. We compared the rate of clinical outcomes between 2-7 and ≥8 days of SAP in first fresh embryo transfer after intracytoplasmic sperm injection (ICSI) in groups of young maternal age (YMA: <38 years) and old maternal age (OMA: ≥38 years). We conducted a retrospective study of 449 first ICSI cycles with a normal ovarian response. SAP was identified before collecting the semen samples. Semen analysis was performed based on the guidelines recommended by WHO (2010). Sperm preparation was made using the swim-up method. Patients' baseline characteristics in the YMA and OMA groups did not differ. The rates of fertilisation, top-quality embryos on day 3, biochemical pregnancy, clinical pregnancy, ongoing pregnancy, abortion and implantation per cycle were not significantly different between 2-7 and ≥8 days of SAP in the YMA or OMA group. In conclusion, SAP beyond the recommended period by WHO was not associated with the rates of a lower fertilisation and pregnancy in human in vitro fertilisation (IVF). We think that a new criterion of SAP for clinical application in human IVF needs to be considered by WHO.

Effects of depression co-morbidity and treatment on quality of life in patients with acute coronary syndrome: the Korean depression in ACS (K-DEPACS) and the escitalopram for depression in ACS (EsDEPACS) study.

BACKGROUND: Depression is common after acute coronary syndrome (ACS) with adverse effects on prognosis. There is little evidence on whether depression treatment improves quality of life (QoL) in ACS patients. The aim of this study was to investigate the effects of co-morbid depression and its treatment on QoL in ACS. METHOD: In total, 1152 patients were recruited at baseline, 2-14 weeks after a confirmed ACS episode, and 828 were followed 1 year thereafter. Of 446 baseline participants with co-morbid depressive disorders, 300 were randomized to a 24-week double blind trial of escitalopram or placebo, while the remaining 146 received medical treatment only (MTO). QoL was measured by the World Health Organization Quality of Life -Abbreviated form (WHOQOL-BREF). RESULTS: At baseline, QoL was significantly lower in patients with co-morbid depressive disorder than those without. QoL improvement was significantly greater in those receiving escitalopram than those receiving placebo over the 24-week treatment period. In the 1-year follow-up, the better outcomes associated with escitalopram remained evident against both placebo and MTO. CONCLUSIONS: Depression was significantly associated with worse QoL even in patients with recently developed ACS. Depression treatment was associated with QoL improvement in ACS patients in the 24-week treatment period, the effects of which extended to 1 year.

Cutaneous Serratia marcescens infection in two dogs.

We describe two canine cases of cutaneous infection caused by Serratia marcescens. A 2-year-old castrated male mixed dog (Case 1) presented with multiple ulcerations on the dorsal trunk, which were observed 4 days after shampooing. A 4-year-old male wolf shepherd mix dog (Case 2) presented with ulceration and purulent discharge on the nasal bridge. Cytological examination of both cases revealed pyogranulomatous inflammatory cells with rod-like infectious agents identified as S. marcescens in aerobic bacterial culture. Both patients were treated with oral antibiotics and topical chlorhexidine. Case 1 received enrofloxacin 10 mg/kg once daily for 1 week, followed by trimethoprim/sulfamethoxazole 15 mg/kg twice daily for 3 weeks. Case 2 received doxycycline 10 mg/kg twice daily for 4 weeks. No skin lesions were detected 2 weeks after the initial administration. The antibiotics were discontinued after a total 4 weeks of administration, and the skin lesions did not reappear.

Impact of personality and depression on quality of life in patients with severe haemophilia in Korea.

Among reports on the psychological variables that influence quality of life (QoL), none has addressed the impact of personality on QoL in patients with haemophilia. We investigated the impact of psychosocial variables including depression and personality on QoL in patients with severe haemophilia. A cross-sectional survey examining psychosocial and clinical characteristics was administered to Korean patients with severe haemophilia. Personality traits were ascertained using the 10-item short version of the Big Five Inventory, which quantifies five personality dimensions including extraversion, agreeableness, conscientiousness, neuroticism and openness. Patient QoL and depression were measured by the World Health Organization Quality of Life-abbreviated version and the Beck Depression Inventory (BDI) respectively. Multivariate linear regression analyses were used for each domain to determine the impact of psychological variables on QoL. Of the 53 subjects who consented to participate, 46 cases were finally analysed. Multivariate linear regression analyses demonstrated that agreeableness was significantly and positively associated with the physical health domain of QoL. Openness was independently and positively associated with the psychological and social relationship domains of QoL. BDI scores were significantly and negatively associated with all four domains of the QoL. Persistent pain and joint impairment showed strong associations with all domains in a univariate analysis, but the impact was attenuated after adjusting for psychosocial variables. Personality and depression had strong impacts on QoL independent of physical status in patients with severe haemophilia. Providing psychological screening and intervention are recommended for enhancing QoL in patients with severe haemophilia.

Effects of synchronization of carbohydrate and protein supply in total mixed ration with korean rice wine residue on ruminal fermentation, nitrogen metabolism and microbial protein synthesis in holstein steers.

Three Holstein steers in the growing phase, each with a ruminal cannula, were used to test the hypothesis that the synchronization of the hourly rate of carbohydrate and nitrogen (N) released in the rumen would increase the amount of retained nitrogen for growth and thus improve the efficiency of microbial protein synthesis (EMPS). In Experiment 1, in situ degradability coefficients of carbohydrate and N in feeds including Korean rice wine residue (RWR) were determined. In Experiment 2, three total mixed ration (TMR) diets having different rates of carbohydrate and N release in the rumen were formulated using the in situ degradability of the feeds. All diets were made to contain similar contents of crude protein (CP) and neutral detergent fiber (NDF) but varied in their hourly pattern of nutrient release. The synchrony index of the three TMRs was 0.51 (LS), 0.77 (MS) and 0.95 (HS), respectively. The diets were fed at a restricted level (2% of the animal's body weight) in a 3×3 Latin-square design. Synchronizing the hourly supply of energy and N in the rumen did not significantly alter the digestibility of dry matter, organic matter, crude protein, NDF or acid detergent fiber (ADF) (p>0.05). The ruminal NH3-N content of the LS group at three hours after feeding was significantly higher (p<0.05) than that of the other groups; however, the mean values of ruminal NH3-N, pH and VFA concentration among the three groups were not significantly different (p>0.05). In addition, the purine derivative (PD) excretion in urine and microbial-N production (MN) among the three groups were not significantly different (p>0.05). In conclusion, synchronizing dietary energy and N supply to the rumen did not have a major effect on nutrient digestion or microbial protein synthesis (MPS) in Holstein steers.

Superior mesenteric artery syndrome in a tetraplegic patient, 11 years after a spinal cord injury: a case report.

STUDY DESIGN: Case report. OBJECTIVE: To report on the need to consider the possibility of the superior mesenteric artery syndrome (SMAS) even after a long time from the initial spinal cord injury. SETTING: Ulsan, South Korea. METHODS: A 41-year-old man with complete tetraplegia was evaluated for nausea and vomiting. He had a cervical cord injury 11 years previously and his body mass index was 18.6 on admission. The contrast-enhanced abdominal computed tomography (CT) showed intestinal obstruction at the third-portion of the duodenum. With frequent position change and intravenous electrolyte support, the symptoms resolved. There was no relapse of the symptoms with some lifestyle modifications. CONCLUSION: Patients with spinal cord injury may develop SMAS even long after their initial injury.

Development of an in vitro submerged culture system to synthesize epidermal ceramides in canine keratinocytes.

Ceramides (CERs) in the stratum corneum (SC) are known to play a crucial role in determining skin barrier function in dogs. We aimed to develop an in vitro culture system that synthesized epidermal CER classes to better understand the synthesis of CER classes in canine SC-. Canine keratinocyte cells (MSCEK) at appropriate confluency were incubated with high Ca2+ (1.8 mM CaCl2) supplemented serum-free medium. Eight days post Ca2+ application, the surface of cultured MSCEK was broadly stained with anti-loricrin antibody implying that the keratinocytes had stratified into stratum granulosum. MSCEK cells synthesized heterogenous epidermal CERs, similar to those seen during the stratification of canine keratinocytes. CER fractions obtained from MSCEK cells were comparable to those from canine SC, including CER[EOS] (combination of ω-hydroxy fatty acids and sphingosines), CER[NP] (combination of non-hydroxy fatty acids and phytosphingosines), and CER[EOP] (combination of ω-hydroxy fatty acids and phytosphingosines), all of which are lowered in the SC during canine atopic dermatitis. Thus, the present study provides a simple culture system as a tool for in-depth analysis of CER production in canine keratinocytes.

Prognosis of surgical hernia repair in cirrhotic patients with refractory ascites.

BACKGROUND: Abdominal wall hernias are common in patients with ascites. Elective surgical repair is recommended for the treatment of abdominal wall hernias. However, surgical hernia repair in cirrhotic patients with refractory ascites is controversial. In this study, we aimed to evaluate the outcomes of elective surgical hernia repair in patients with liver cirrhosis with and without refractory ascites. METHOD: From January 2005 to June 2018, we retrospectively reviewed the records of consecutive patients with liver cirrhosis who underwent a surgical hernia repair. RESULTS: This study included 107 patients; 31 patients (29.0%) had refractory ascites. Preoperatively, cirrhotic patients with refractory ascites had a higher median model for end-stage liver disease (MELD) score (13.0 vs 11.0, P = 0.001) than those without refractory ascites. The 30-day mortality rate (3.2% vs 0%, P = 0.64) and the risk of recurrence (hazard ratio 0.410; 95% CI 0.050-3.220; P = 0.39) did not differ significantly between cirrhotic patients with refractory ascites and cirrhotic patients without refractory ascites. Among cirrhotic patients with refractory ascites, albumin (P = 0.23), bilirubin (P = 0.37), creatinine (P = 0.97), and sodium levels (P = 0.35) did not change significantly after surgery. CONCLUSION: In advanced liver cirrhosis patients with refractory ascites, hernias can be safely treated with elective surgical repair. Mortality rate within 30 days did not differ by the presence or absence of refractory ascites. Elective hernia repair might be beneficial for treatment of abdominal wall hernia in cirrhotic patients with refractory ascites.

Mutations, chromosomal aberrations, and tumors in insects treated with oncogenic virus.

An increased incidence of lethal mutations, visible mutations, chromosomal losses, chromosomal nondisjunctions, and tumors resulted when drosophila were placed in medium containing Rous-sarcoma virus. In the group treated, a few mosaics of the eye and translocations appeared as well. There is a suggestion, from preliminary data, that the size of chromosomal puffs may be reduced by this RNA virus, but the difference is not significant. Tests for the persistence of virus in progeny have been negative so far.

Heterogeneity in the processing defect of SLC26A4 mutants.

BACKGROUND: Mutations in the SLC26A4 gene are responsible for Pendred syndrome and non-syndromic hearing loss (DFNB4). This study analysed non-synonymous SLC26A4 mutations newly identified in East Asians, as well as three common mutations in Caucasians, to characterise their molecular pathogenic mechanisms and to explore the possibility of rescuing their processing defects. METHODS: A total of 11 non-synonymous disease associated mutations were generated and their effects on protein processing and on ion transporting activities were examined. RESULTS: Most of the mutations caused retention of the SLC26A4 gene product (pendrin) in the intracellular region, while wild-type pendrin reached the plasma membrane. Accordingly, these mutations abolished complex glycosylation and Cl(-)/HCO(3)(-) exchange activities of pendrin. However, significant heterogeneity in the processing of mutant pendrin molecules was observed. Each mutant protein exhibited a different cellular localisation, a different degree of N-glycosylation, and a different degree of sensitivity to the treatments that rescue processing defects. For example, H723R-pendrin, the most common mutation in East Asians, was mostly expressed in endoplasmic reticulum (ER), and its defects in protein processing and ion transporting activities were restored considerably by low temperature incubation. On the other hand, L236P-pendrin, the most common mutation in Caucasians, was mainly in the centrosomal region and was temperature insensitive. CONCLUSION: These results indicate that the processing of pendrin mutant protein is determined by mutant specific mechanisms, and that a mutant specific method would be required to rescue the conformational defects of each folding mutant.

Substance P as a potential biomarker of pain assessment in dogs.

BACKGROUND: Substance P (SP) is a neuropeptide that functions as a neuromodulator. It is released mainly in the brain stem and in nerve endings. AIMS: The present study aimed to provide fundamental data that may be applied to the assessment of pain in dogs by evaluating their serum SP concentrations. METHODS: Two groups of dogs were designated as pain groups that included 10 dogs with medial patella luxation (MPL) and 10 dogs with fractures, respectively, and 20 healthy dogs were enrolled as the control group. RESULTS: The SP concentrations in the serum of the pain groups reached 485.5 ± 250.1 pg/ml that was significantly higher than those of the control group, which reached 116.4 ± 38.5 pg/ml. In particular, serum SP concentrations in dogs with fractures (663.3 ± 225.3 pg/ml) were significantly higher compared to those of dogs with MPL (307.8 ± 105.3 pg/ml), indicating that serum SP levels increased when the dogs experienced greater pain. CONCLUSION: These findings propose the possibility that SP might be a useful biomarker for pain assessment in dogs. The present study may provide fundamental data that can aid in future pain management in dogs.

Changes in folate, vitamin B12 and homocysteine associated with incident dementia.

OBJECTIVES: Prospective findings have not been consistent for folate, vitamin B(12) and homocysteine concentrations as predictors of dementia. This study aimed to investigate both baseline concentrations of folate, vitamin B(12) and homocysteine and changes in these concentrations as predictors/correlates of incident dementia. METHODS: Of 625 elderly patients without dementia at baseline, 518 (83%) were followed over a 2.4 year period and were clinically assessed for incident dementia and Alzheimer's disease (AD). Serum concentrations of folate, vitamin B(12) and homocysteine were measured at the baseline and follow-up assessments. Covariates included age, sex, education, disability, depression, alcohol consumption, physical activity, vascular risk factors, serum creatinine concentration, vitamin intake and weight change. RESULTS: Only baseline lower folate concentrations predicted incident dementia. The onset of dementia was significantly associated with an exaggerated decline in folate, a weaker increase in vitamin B(12) concentrations and an exaggerated increase in homocysteine concentrations over the follow-up period. These associations were reduced following adjustment for weight change over the same period. CONCLUSIONS: Incident dementia is more strongly associated with changes in folate, vitamin B(12) and homocysteine than with previous concentrations. These changes may be linked to other somatic manifestations of early dementia, such as weight loss.

Peroneal neuropathy after liver transplantation.

INTRODUCTION: The incidence of peroneal neuropathy (PN), occurring predominantly in the left leg, increases after the incorporation of intermittent pneumatic compression (IPC) devices among adult liver transplantation (OLT) recipients in our hospital. The aim of this study was to investigate the possible risk factors for PN and the reason for the left-leg predominance. METHODS: We retrospectively reviewed the medical records of 501 OLT recipients. The patients were first divided into 2 groups, PN (n = 33) and non-PN (n = 468), to assess possible risk factors. The patients were then categorized into IPC (n = 262) and non-IPC (n = 239) groups according to the use of IPC devices. In a subsequent prospective study, we measured the degree and duration of the tilt of the operating table during OLT to investigate their relationship to the predominant left-leg PN. RESULTS: The rate of IPC device use was significantly greater among the PN than non-PN group (78.8% vs 50.4%, P < .01). The incidence of PN was significantly higher among the IPC than non-IPC group (9.9% vs 2.9%, P < .01). The degree and duration of left tilt of the operating table were greater and longer than the right tilt. CONCLUSIONS: The use of IPC devices during OLT increased the occurrence of PN and the left tilt of the operating table was strongly related to the predominant left-leg PN. Careful protection of the vulnerable point and minimization of the tilting of the operating table is advised during OLT, especially when IPC devices are used.

Effect of topical loteprednol etabonate with lid hygiene on tear cytokines and meibomian gland dysfunction in prosthetic eye wearers.

PurposeTo assess tear cytokine levels and clinical outcomes in meibomian gland dysfunction (MGD) in the blind eye of patients wearing an ocular prosthesis after 2 months of treatment with topical loteprednol etabonate and eyelid scrubs with warm compresses.Patients and methodsThis study included patients with MGD wearing a unilateral ocular prosthesis for more than 1 year. All patients topically received 0.5% loteprednol etabonate and were instructed to scrub their eyelids with warm compresses on the prosthetic eye for 2 months. We evaluated tear cytokine levels using Multiplex Bead Immunoassays, performed biomicroscopic examination of the lid margins and meibomian gland, conducted meibography imaging, and assessed MGD-related ocular symptoms using a questionnaire for the prosthetic eye before and 2 months after treatment.ResultsThirty consecutive patients were included. There were significant reductions in the levels of interleukin (IL)-6, interferon-γ, monocyte chemotactic protein-1, IL-8, tumor necrosis factor-α, and IL-1ß (P<0.001 for each cytokine). Moreover, there were improvements in ocular symptoms (P=0.001), lid margin abnormalities (P<0.001), meibomian gland expressibility (P<0.001) and meibography findings (P=0.037).ConclusionTopical loteprednol etabonate in conjunction with eyelid scrubs and warm compresses were effective in treating MGD in prosthetic eye wearers. Furthermore, tear cytokine measurements may serve as an additional approach for evaluating the efficacy of anti-inflammatory treatment for MGD in prosthetic eye wearers.

In vitro selection and characterization of human immunodeficiency virus type 1 resistant to Zidovudine and tenofovir.

In this study, we undertook to generate HIV-1 resistance to PMPA by in vitro passage and to characterize the cross-resistance patterns and RT mutations in the generated resistant virus. The HIV-1 A102-resistant to AZT was serially passaged for 4 months in the presence of increasing concentrations of PMPA up to maximum of 40 microM on the fresh MT-2 cells. After 25 passages, HIV-1 developed decreased sensitivity to PMPA after long-term in vitro exposure. Selected HIV-1 mutants were characterized by decreased susceptibility to PMPA (4-fold). This decrease could be related to PMPA resistant caused by an amino acid change associated with a V148M substitution. From these results, additional studies will be needed to determine whether a similar mutation in HIV RT develops in patients receiving PMPA or its orally bioavailable prodrug, tenofovir dipivoxil fumarate.

Preoperative clinical features of reactivated of Graves' orbitopathy after orbital decompression.

PurposeTo investigate the incidence and preoperative clinical features of reactivated Graves' orbitopathy (GO) after orbital decompression.MethodsThis study included patients with GO who underwent orbital decompression for disfiguring proptosis and not compressive optic neuropathy and received postoperative follow-up care for more than 12 months. Patients who experienced active inflammatory signs within 6 months of decompression were excluded from analysis. The demographic characteristics, ophthalmic manifestations, and biochemical parameters of the patients were analyzed for association with reactivation of GO by logistic regression analysis.ResultsOut of the 92 patients included in this study, seven (7.6%) experienced reactivation of GO after orbital decompression. The mean time interval between surgery and reactivation of GO was 36.3±14.3 weeks. Univariate logistic regression analysis identified age, existing smoking habits, and modified NOSPECS and Gorman scores as significant factors for the reactivation of GO. The results of multivariate logistic regression analysis revealed that smoking and modified NOSPECS and Gorman scores were associated with the reactivation of GO.ConclusionsQuitting smoking is important for the prevention of reactivation of GO after orbital decompression. Patients with severe symptoms, especially those with restrictive myopathy, should be carefully monitored for reactivation of GO after orbital decompression.

Inhibition of UL54 and UL97 genes of human cytomegalovirus by RNA interference.

Short interfering RNAs (siRNAs), namely siUL54-1 and siU54-2 targeting UL54 (DNA polymerase) gene, and siUL97-1 and siUL97-2 targeting UL97 (phosphotransferase) gene, were used to inhibit respective genes of Human cytomegalovirus (HCMV) and consequently the virus infection process in human foreskin fibroblast (HFF) cultures. The virus infection was monitored by cell morphology (CPE), levels of UL83 and IE86 mRNAs, and virus antigen. The results showed that siUL97-2 remarkably inhibited viral CPE while other siRNAs were less inhibitory. The siRNAs reduced the levels of UL83 mRNA but not that of IE86 mRNA; again, siUL97-2 was most inhibitory. Particularly, siUL97-2 reduced the UL83 mRNA level 14, 19, 203, and 37 times at 24, 48, 72, and 96 hrs post infection (p.i.), respectively. When tested for the effect on viral antigen by immunofluorescent assay (IFA), UL97-2 exerted a marked inhibition. These results demonstrate the effectiveness of siRNAs against experimental HCMV infection and indicate their therapeutic potential.

Immunohistochemical characterization of sebaceous epithelioma in two dogs.

This report describes two cases of sebaceous epithelioma and its immunohistochemical characterization with CK 14, CK18, p63, Ki67 and Bcl-2 immunostaining. Case 1 was a 12-year-old, intact English Cocker spaniel female presenting with multiple skin nodules over one year. Case 2 was a 7-year-old, spayed poodle female with a five-month history of solitary mass. Hematoxylin and eosin (H&E) staining showed that the nodules in both cases were irregular lobules comprised of epithelial cells around well-differentiated sebocytes. Neoplastic cells were positive for CK14 and p63 but were negative for CK18 cell marker. In addition, immunostaining for Ki67 proliferation marker showed 13.1% and 12.4% positive cells in the two cases, respectively. Furthermore, Bcl-2, which is highly expressed in human benign sebaceous tumors, was seen in basaloid cell nuclei and cytoplasm. CK14, CK18, p63, Ki67, and Bcl-2 antibody application provided further information for diagnosing sebaceous epithelioma and for prognosis in these two cases.

Impaired RBC deformability is associated with diabetic retinopathy in patients with type 2 diabetes.

AIM: Red blood cell (RBC) deformability, the ability of RBCs to change shape under stress, is known to be decreased in type 2 diabetes (T2D). However, as yet little is known of the association between RBC deformability and diabetic complications in T2D. For this reason, this study has investigated the association between RBC deformability and diabetic complications. METHODS: In this cross-sectional study, 452 T2D patients were initially enrolled. RBC deformability was measured using a microfluidic ektacytometer and expressed as an elongation index at 3Pa (EI@3Pa, %). RESULTS: A final total of 373 patients (mean age: 60.04±11.93 years; males: 201) were included in the study. When categorized into quartiles of RBC deformability, the lower EI@3Pa groups had higher glycated haemoglobin (HbA1c), triglycerides and prevalence of diabetic retinopathy compared with the higher quartiles (P<0.05 for trend). In particular, the EI@3Pa was significantly lower in patients with retinopathy than in those without retinopathy (30.53±1.95 vs 31.20±1.53, P=0.001). Between the lowest EI@3Pa quartile (Q1) to the highest (Q4, reference), the odds ratio (OR) for Q1 was 2.81 (95% CI: 1.21-6.49, P=0.004 for trend), after adjusting for age, gender, presence of hypertension and smoking, duration of diabetes, HbA1c, glomerular filtration rate and triglycerides. CONCLUSION: In terms of diabetic complications, the lowest EI@3Pa group was closely associated with only the risk of diabetic retinopathy in our study. These results suggest that RBC deformability might be contributory to the development of the microvascular complication.
