Retinopathy in severe aplastic anaemia

Association between HDL cholesterol with diabetic retinopathy in diabetic patients: a cross-sectional retrospective study

OBJECTIVE

Diabetic patients are often comorbid with dyslipidemia, however, the relationship between high-density lipoprotein cholesterol(HDL-C) and diabetic retinopathy (DR) in the adult diabetic population remains to be fully elucidated.The aim of this study is to evaluate the associations between HDL-C and DR in the United States adults with diabetes.

METHODS

A total of 1708 participants from the National Health and Nutrition Examination Survey (NHANES) 2005-2008 were enrolled in the present study. Fundus images of all study subjects were captured and evaluated using a digital camera and an ophthalmic digital imaging system, and the diagnosis of DR was made by the severity scale of the Early Treatment Diabetic Retinopathy Study (ETDRS).Roche Diagnostics were used to measure serum HDL-C concentration. The relationship of DR with HDL-C was investigated using multivariable logistic regression. The potential non-line correlation was explored with smooth curve fitting approach.

RESULTS

The fully-adjusted model showed that HDL-C positively correlated with DR(OR:1.69, 95%CI: 1.25-2.31).However, an inverted U-shaped association between them was observed by applying the smooth curve fitted method. The inflection point of HDL-C(1.99mmol/l) was calculated by utilizing the two-piecewise logistic regression model. In the subgroup analysis, the inverted U-shaped nonlinear correlation between HDL-C and DR was also found in female, Non-Hispanic White, and lower age groups.

CONCLUSION

Our study revealed an inverted U-shaped positive relationship between HDL-C and DR.The findings may provide us with a more comprehensive understanding of the association between HDL-C and DR.

Analysis of Continuous Nursing Intervention on Aplastic Anemia Patients Based on the "Information-Motivation-Behavioral Skills Model"

Objective

To explore the effect of continuous nursing care based on the “information-motivation-behavioral skills model” (IMB) in the intervention of patients with aplastic anemia.

Methods

A total of 90 patients with aplastic anemia who were admitted to our hospital from June 2019 to January 2021 were included in the study. The patients were divided into an observation group and a control group according to the random number table, with 45 patients in each group. The control group received routine nursing care, while the observation group received continuous nursing care based on IMB on the basis of the control group. Patients were followed up for 3 months, and their health knowledge was assessed with our self-made health knowledge rating scale. Patients' medication compliance was assessed using the Morisky medication compliance questionnaire. The self-care ability was assessed with the self-made self-care ability scale in our hospital. The comprehensive quality of life assessment questionnaire (GQOLI-74) was used to assess the quality of life of patients. A self-prepared nursing satisfaction questionnaire was used to score patients' nursing satisfaction. The total effective rate of nursing was evaluated.

Results

The awareness scores of basic disease knowledge, medication knowledge, and daily self-care knowledge in the observation group were higher than those in the control group (P < 0.05). The scores of medication compliance in the observation group were higher than those in the control group (P < 0.05). The self-care abilities such as healthy diet, psychological adjustment, self-care skills, oral care, and perianal care in the observation group were higher than those in the control group (P < 0.05). The quality of life scores of patients in the two groups in the 3 months of nursing were higher than those when they were discharged from hospital (P < 0.05). The GQOLI-74 score of 3 months' nursing care in the observation group was higher than that in the control group (P < 0.05). The nursing satisfaction degree of the observation group (97.78%) was higher than that of the control group (82.23%) (P < 0.05). The total effective rate of nursing care in the observation group (97.78%) was higher than that in the control group (77.78%) (P < 0.05).

Conclusion

IMB-based continuous nursing care can significantly increase the awareness of health knowledge in patients with aplastic anemia, effectively improve medication compliance, significantly enhance self-care ability, and thus, improve the quality of life.

Spontaneously resolved severe retinopathy associated with aplastic anemia

Aplastic anemia is a rare, usually autoimmune disorder of bone marrow stem cells leading to pancytopenia and hypoplastic marrow that presents with anemia, infection or bleeding which can be potentially sight and life-threatening. Patients with aplastic anemia may present with various ocular manifestations; lid and orbital hematoma, sub-conjunctival hemorrhage, sudden visual loss due to vitreous hemorrhage or retinopathy and optic disc edema. A young male patient had symptomatic sever bilateral hemorrhagic retinopathy secondary to aplastic anemia; succeeding systemic allogenic hematopoietic stem-cell transplantation showed almost complete spontaneous resolution of the retinopathy and significant improvement in vision over a period of 16 weeks.
