As medicine strives to become more patient-centered, patient-reported outcomes (PROs) are often used to describe patients' symptoms, function, and quality of life. This review describes the key concepts of PROs specific to heart failure in clinical trials and their potential role in clinical practice.
As the Food and Drug Administration has increasingly emphasized how it values PROs as clinical outcome assessments, including its recent qualification of the Kansas City Cardiomyopathy Questionnaire (KCCQ), clinical trials have increasingly used them to evaluate novel therapies. This has been enhanced by an increasing understanding of how to interpret KCCQ scores. Its use in clinical practice, including the importance of providers sharing results with their patients, is just emerging. PROs provide unique insights into the benefits of treatment from patients' perspectives and while their role in clinical care is just beginning, they offer an important opportunity to improve the patient-centeredness of care.

In the present research, the permeation barrier, selectivity and all thermodynamic functions for passing of four different molecules including CH4, H2S, N2 and CO2 gases on four types of porous graphene which is doped by two, three and six nitrogen atoms using quantum mechanical modelling, based on the density functional theory, B97D, and cc-pVTZ basis set have been evaluated. We find that the permeation barrier of all studied gases especially carbon dioxide decreased by considering the functionalized porous graphene by two, three and six nitrogens-doped, respectively. The results of our study propose using a porous graphene sheet as highly efficient and highly selective membranes for gas separations.
The aim of this study was to introduce a complete 3D workflow for immediate implant retained prosthetic rehabilitation following maxillectomy in cancer surgery. The workflow consists of a 3D virtual surgical planning for tumor resection, zygomatic implant placement, and for an implant-retained prosthetic-obturator to fit the planned outcome situation for immediate loading.
In this study, 3D virtual surgical planning and resection of the maxilla, followed by guided placement of 10 zygomatic implants, using custom cutting and drill/placement-guides, was performed on 5 fresh frozen human cadavers. A preoperatively digitally designed and printed obturator prosthesis was placed and connected to the zygomatic implants. The accuracy of the implant positioning was obtained using 3D deviation analysis by merging the pre- and post-operative CT scan datasets.
The preoperatively designed and manufactured obturator prostheses matched accurately the per-operative implant positions. see more All five obturators could be placed and fixated for immediate loading. The mean prosthetic point deviation on the cadavers was 1.03 ± 0.85 mm; the mean entry point deviation was 1.20 ± 0.62 mm; and the 3D angle deviation was 2.97 ± 1.44°.
It is possible to 3D plan and accurately execute the ablative surgery, placement of zygomatic implants, and immediate placement of an implant-retained obturator prosthesis with 3D virtual surgical planning.The next step is to apply the workflow in the operating room in patients planned for maxillectomy.

To compare clinical, functional, and radiological outcomes in patients with bicondylar tibial fractures treated with either double-plate or Ilizarov external fixation.
Patients with Schatzker type 5 and 6 tibial plateau fractures who were treated with double-plate (Group O) and Ilizarov external fixations (Group E) between March 2012 and April 2018 were selected. Demographic data and preoperative, intraoperative, and postoperative variables were analyzed and compared. In the last follow-up, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford Knee Score (OKS), Knee Society Score-Knee (KSS-Knee), KSS-Function (KSS-F), and Short-Form Health Survey (SF-36) were used to measure clinical and functional outcomes. Treatment costs and complication rates were also recorded and compared.
A total of 64 patients (43 men and 21 women) were included in the study (group O 36, group E 28). WOMAC, KSS-F, KSS-Knee, and OKS scores were similar between the two groups (P > 0.05). The role limitations due to emotional problems, emotional well-being, and social functioning domains of SF-36 were higher in group O (P < 0.001). Three (8.3%) deep infections occurred in group O, whereas no deep infection was observed in group E (P = 0.035). The treatment cost was higher in group O (P < 0.001).
In bicondylar tibial plateau fractures, functional outcomes of ORIF and Ilizarov method milar were sibut, role limitations due to emotional problems, emotional well-being and social functioning domains of SF-36 score were higher in ORIF group. However, Ilizarov method is more cost-effective and related with lesser complications.

During a standard dorsal longitudinal mid-line approach to the carpus, an extensor digitorum brevis manus (EDBM) muscle was found taking its origin from the dorsal wrist capsule overlying the lunate with innervation from the posterior interosseous nerve (PIN). Electrical stimulation of the muscle belly demonstrated abduction of the middle finger. The EDBM is a rare anatomical variant of the extensor compartment of the wrist and may be encountered during surgical approaches. Where possible these variant muscles should be carefully dissected off underlying structures, preserved and repaired at the conclusion of a procedure to ensure no perceived functional deficit to the patient. We present a case of a previously undescribed EDBM muscle function of pure finger abduction with no extension and a surgical technique of preserving its origin. We propose that the middle finger variant of the EDBM should be re-named the extensor digitorum brevis medius to reflect our findings.
Ultrasound with superb microvascular imaging (SMI) is a novel microvascular imaging technology which may be useful to assess the vascularity of the torn anterior cruciate ligament (ACL) as a potential measure of healing potential following surgery. This study aimed to quantify the vascularity of the torn and intact ACL using ultrasound with SMI.
23 patients (mean age ± standard deviation, 27.1 ± 12.8years), who were diagnosed with an ACL tear with an intact contralateral ACL were enrolled (ACL injury group). Ten healthy volunteers (36.1 ± 4.9years) who had intact ACLs in both knees were also recruited (ACL healthy controls). The vascularity of the ACL was assessed using SMI within 15mm from the tibial insertion in both knees. The amount of the vascular signal was assessed using a semi-quantitative grading scale (vascularity grade grade 0-3) and a quantified ratio of vascularized area with respect to total area of the region of interest (vascularity ratio).
In the ACL injury group, a significantly higher vascularity grade and ratio were observed in the torn ACL (vascularity grade 0-3 1, 8, 7, and 7 patients, respectively; vascularity ratio 1.3 ± 1.4%) than the contralateral intact ACL (vascularity grade 0-3 21, 1, 1, and 0 patients, respectively; vascularity ratio 0.1 ± 0.5%) (P < 0.001), whereas no significant difference was observed between both ACLs in the ACL healthy control group.
SMI was useful to assess the increased vascularity in torn ACL, which may reflect the potential for, or state of, ACL maturation following reconstruction or repair.

We postulated that the increased lifetime risk of chronic kidney disease (CKD) in young-onset diabetes is attributable to both long disease duration and more aggressive disease. We examined whether age at diabetes diagnosis modifies the effect of diabetes duration on risk of CKD.
We included 436,744 people with incident type 2 diabetes in the Hong Kong Diabetes Surveillance Database (HKDSD) and 16,979 people with prevalent type 2 diabetes in the Hong Kong Diabetes Register (HKDR). We used Poisson models to describe joint effects of age at diabetes diagnosis, diabetes duration and attained age on incidence of CKD in HKDSD. We used Cox proportional hazards models to examine interaction effect of age at diabetes diagnosis and diabetes duration on risk of CKD with adjustment for confounders in HKDR.
During a median follow-up of 5.3years, 134,043 cases of CKD were recorded in the HKDSD. The incidence rate ratio for CKD comparing people of the same attained age but diagnosed with diabetes at ages 5years apart was higher for people with a younger age at diabetes diagnosis, but decreased with increasing age at diabetes diagnosis. During a median follow-up of 6.3years, 6500 people developed CKD in the HKDR. The increased risk of CKD with longer diabetes duration decreased with older age at diabetes diagnosis. The adjusted HR for CKD associated with 5year increase in diabetes duration was 1.37 (95% CI 1.13, 1.65) in people with diabetes diagnosed at 20-29years and 1.01 (95% CI 0.87, 1.18) in those diagnosed at ≥70years.
Young age at diabetes diagnosis amplified the effect of increasing diabetes duration on increased risk of CKD.

To evaluate the factors associated with the development of ocular candidiasis (OC) and ocular prognosis with echinocandin therapy for candidemia.
The medical records of 56 consecutive patients with a positive blood culture for Candida species between November 2016 and October 2019 were retrospectively reviewed. Information on patient characteristics, isolated Candida species, treatment details for candidemia, and ocular findings were extracted to identify factors associated with OC development.
The leading pathogen of candidemia was Candida albicans(C.albicans) (41.1%). Of 56 patients, 18 (32.1%) were diagnosed with chorioretinitis, categorized as either probable (8 patients) or possible OC (10 patients). There was no case of endophthalmitis with vitritis. The incidence of probable OC was not significantly different between the groups treated with echinocandins and other antifungal drugs (15.2% vs. 11.1%, p = 1.00). In all probable OC cases, systemic antifungal therapy was switched from echinocandins to azoles, and no case progressed to endophthalmitis.
