AimsWe examined the impact of memory complaints on the concordance between self-report (SR) and electronically monitored (EM) medication adherence, independent of depression symptoms, among adults with type 2 diabetes (T2D).MethodsAdults (N = 104, age = 56.6 ± 9.2; 64% female) completed a prospective and retrospective memory questionnaire (PRMQ) and a depression symptom interview at baseline. EM was tracked over 3 months and participants rated adherence using SR. Multiple linear regression evaluated PRMQ as a moderator of the relationship between EM and SR, adjusting for depression and other covariates.ResultsPRMQ was correlated with lower SR (r = ?0.31, p = 0.001), but not with EM. PRMQ moderated the relationship between SR and EM, independent of depression symptoms. At low levels of PRMQ, SR and EM were closely related (β = 0.76, p < 0.001); at high levels of PRMQ the relationship was weaker (β = 0.28, p = 0.02). Participants who under-reported their adherence (SR < EM) had higher PRMQ scores than more concordant reporters (p = 0.016).ConclusionsSR and EM measures were less concordant among adults with T2D who endorsed higher PRMQ scores. Memory complaints may contribute to under-reporting of medication adherence in adults with T2D.  相似文献

BackgroundProximal tibia vara has drawn interest since the concept of constitutional varus was introduced. Proximal tibia vara is a condition where the knee varus tilt the tibia condyle medially and shift the tibial articular surface medially. This condition affects medial proximal tibial angle measurements and the placement of the tibial implant in knee replacement surgery. Thus, it challenged the neutral knee arthroplasty alignment target because some people may present a proximal tibia vara. This study assesses the prevalence of the proximal tibia vara and the correlation to knee osteoarthritis grade.MethodsThis retrospective study was carried out from January 2021 to June 2021. Eighty-five limbs were included with the following inclusion criteria: knee osteoarthritis patients who received a long view lower extremity radiograph. The exclusions criteria were (1) patients who had undergone arthroplasty and lower extremity surgery before and (2) valgus knee deformity. The outcomes in this study were HKAA, MAD, TAD, MPTA, PTRP, LDFA, and PTS. Intraclass correlation (ICC) using two-way mixed was used to assess the reproducibility of the radiographic parameters. Multiple logistic regression was used to evaluate the correlation between knee osteoarthritis grade and radiographs parameters (MAD and TAD).ResultA total 85 limbs from 52 patients were assessed in this study. Proximal tibia vara was found in 18 knees (21%.). The logistic regression was performed to assess the correlation between the severity of the knee osteoarthritis and radiographic parameters (MAD, TAD, LDFA, and PTS) with an overall p-value < 0.001 and pseudo-R2 = 0.29.ConclusionA significant portion of patients with knee osteoarthritis have proximal tibia vara, and it is a pre-existing condition. Since the pre-existing proximal tibia vara affects preoperative measurements, a long-standing lower extremity x-ray is recommended to be obtained as part of knee replacement preparation.  相似文献
