ABSTRACT
BACKGROUND@#Keloids are benign fibrous growths that are caused by excessive tissue build-up. Severe keloids exert more significant effects on patients' quality of life than do mild keloids. We aimed to identify factors associated with the progression from mild keloids to severe keloids, as distinct from those associated with the formation of keloids.@*METHODS@#In this retrospective case-control study, 251 patients diagnosed with keloids at West China Hospital between November 2018 and April 2021 were grouped according to the severity of lesions (mild [n = 162] or severe [n = 89]). We collected their basic characteristics, living habits, incomes, comorbidities, and keloid characteristics from Electronic Medical Records in the hospital and the patients' interviews. Conditional multivariable regression was performed to identify the independent risk factors for the progression of keloids.@*RESULTS@#Eighty-nine patients (35.5%) were classified as having severe keloids. We found the distribution of severe keloids varied with sex, age, excessive scrubbing of keloids, family income, the comorbidity of rheumatism, disease duration, characteristics of the location, location in sites of high-stretch tension, the severity and frequency of pain, the severity of pruritus, and infection. Multivariable analysis revealed significant associations between severe keloids and infection (odds ratio [OR], 3.55; P = 0.005), excessive scrubbing of keloids (OR, 8.65; P = 0.001), low or middle family income (OR, 13.44; P = 0.021), comorbidity of rheumatism (OR, 18.97; P = 0.021), multiple keloids located at multiple sites (OR, 3.18; P = 0.033), and disease duration > 15 years (OR, 2.98; P = 0.046).@*CONCLUSION@#Doctors should implement more active and thorough measures to minimize the progression of mild keloids in patients who have any of the following risk factors: infection, excessive scrubbing of keloids, low or middle family income, comorbidity of rheumatism, multiple keloids located at multiple sites, and disease duration > 15 years.

Objective To observe the influence of comprehensive rehabilitation on lung function and exercise tolerance in geriatric patients with chronic obstructive pulmonary disease (COPD).Methods Totally 51 patients with COPD were enrolled in this study and divided into two groups:treatment group and control group.For treatment group,each patient was given health education about COPD and the rehabilitation program with medication therapy.The program included aerobic exercises,breathing exercises and upper limb strength training.The control group was given medication therapy only.The treatment group was tested by 6 minute walking distance (6MWT) and both groups had lung function examination before the program started,and were retested 1 year later.Results In the treatment group,lung function including vital capacity (VC),forced expiratory volume in one second (FEV1),FEV1 ％,and 6MWT were significantly improved after 1 year of treatment as compared with those indices before treatment [(2.94±0.67)L vs.(2.62±0.65) L,(2.88±0.70)L vs.(2.58±0.65)L,(1.89±0.79)L vs.(1.60±0.67)L,(80.7±28.3)％ vs.(67.7 ±25.9)％,(426.40±71.37)m vs.(326.23±110.80)m,t=2.86,2.27,4.28,4.73,-3.639,respectively,P=0.006,0.027,0.000,0.000,0.001].There was no significant difference in lung function before versus 1 year after intervention in the control group.After 1 year of intervention,the only difference was in FEV1 ％ between the treatment and control groups [(80.7±28.3)％ vs.(71.90± 16.5) ％,t=9.88,P=0.000].Conclusions Comprehensive rehabilitation can improve the lung function and exercise tolerance in geriatric patients with COPD.
ABSTRACT
@#ObjectiveTo explore the validity of Frenchay Activities Index on Chinese stroke patients.MethodsThe 39 stroke patients as stroke group and 39 healthy subjects as control group were assessed by the same rater using Frenchay Activities Index twice. In the first assessment, Barthel index was addititionally used to measure the activities of daily living for the stroke group. The Spearman's correlation coefficient was used to analyse the concurrent validity of the Barthel Index and Frenchay Activities Index in the stroke group. The paired t test was used to compare the scores of Frenchay Activities Index between two groups.ResultsThe correlation coefficient of Frenchay Activities Index and Barthel Index was 0.727 in the stroke group(P<0.001). The scores of each items and the total scores of the Frenchay Activities Index in the stroke group were significantly lower than that of the control group(P<0.01).ConclusionFrenchay Activities Index is acceptable for stroke.
