ABSTRACT

In primary prevention for cardiovascular diseases, there are significant barriers to adherence including freedom from symptoms, long latency for therapeutic benefits, life-long duration of treatment, and need for combined lifestyle changes. However, to implement more systematic approaches, the focus on adherence improvement needs to be shifted away from patient factors to the effects of the treatment team and healthcare system. In addition to conventional educational approaches, more patient-oriented approaches such as patientcentered clinical communication skills, counseling using motivational strategies, decisionmaking by patient empowerment, and a multi-disciplinary team approach should be developed and implemented. Patients should be involved in a program of self-monitoring, self-management, and active counseling. Because most effective interventions on adherence improvement demand greater resources, the health care system and educational or training system of physicians and healthcare staff need to be supported for systematic improvement.

ABSTRACT

Background@#Single free flaps are a commonly used reconstructive method for multiple soft tissue defects in digits. We analyzed the flap size, division timing, and degree of necrosis in cases with various types of flap division. @*Methods@#We conducted a retrospective review of the medical charts of patients who had undergone single free flap reconstruction for multiple soft tissue defects across their digits from 2011 to 2020. The flap types included were the lateral arm free flap, venous forearm free flap, thenar free flap, hypothenar free flap, anterolateral thigh free flap, medial plantar free flap, and second toe pulp free flap. Flap size, anastomosed vessels, division timing, and occurrence of flap necrosis were retrospectively investigated and then analyzed using the t-test. @*Results@#In total, 75 patients were included in the analysis. The success rate of the free flaps was 97.3%. All flaps were successfully divided after at least 17 days, with a mean of 47.17 days (range, 17–243 days) for large flaps and 42.81 days (range, 20–130 days) for the medium and small flaps (P=0.596). The mean area of flap necrosis was 2.38% in the large flaps and 2.58% in the medium and small flaps (P=0.935). Severe necrosis of the divided flap developed in two patients who had undergone flap division at week 6 and week 34. @*Conclusions@#In cases where blood flow to the flap has been stable for more than 3 weeks, flap division can be safely attempted regardless of the flap size.

ABSTRACT

Background@#Fingertip injuries are very common; however, the reconstruction of volar pulp defects with nail bed defects is challenging in the absence of the amputated segment. We reconstructed fingertip amputations with nail bed defects using a new surgical approach: a subcutaneous flap and composite graft. @*Methods@#We treated 10 fingertip amputation patients without an amputated segment, with exposed distal phalangeal bone and full-thickness nail bed defects between February 2018 and December 2020. All patients underwent two-stage surgery: in the first stage, a subcutaneous flap was performed to cover the exposed distal phalanx, and in the second stage, a composite graft, consisting of nail bed, hyponychium, and volar pulp skin, was applied over the subcutaneous flap. @*Results@#All flaps survived and all composite grafts were successful. The wounds healed without any significant complications, including the donor site. The average follow-up duration was 11.2 months (range, 3–27 months). The new nail and the shape of the volar pulp were evaluated during follow-up. All patients were satisfied with their natural fingertip shapes and the new nails did not have any serious deformities. @*Conclusions@#A subcutaneous flap in combination with a composite graft fitting the shape of the defect could be another option for fingertip injuries without amputated segments.

ABSTRACT

Purpose@#The programmed death protein 1 (PD-1) pathway is the critical mechanism in development of hepatocellular carcinoma (HCC). The present study analyzed the prognostic impact of pretransplant serum soluble PD-1 (sPD-1) concentration and α-FP–des-γ- –tumor volume (ADV) score in patients with previously untreated HCC undergone liver transplantation (LT). @*Methods@#This retrospective single-center study enrolled 100 patients with HCC who underwent living donor LT from 2010 to 2016. Concentrations of sPD-1 were measured in stored serum samples. @*Results@#Receiver operating characteristic curve analysis of 2-year tumor recurrence resulted in an sPD-1 cutoff of 177.1 µg/mL, which was associated with higher rates of tumor recurrence (P = 0.022), but not with overall patient survival (P = 0.460). The derived cutoff for pretransplant ADV score was 5.4log, which was associated with higher tumor recurrence rate (P 177.1 µg/mL (hazard ratio [HR], 2.26; P = 0.020) and pretransplant ADV score of >5.4log (HR, 3.56; P < 0.001) were independent risk factors for posttransplant HCC recurrence. The combination of these 2 factors enabled the stratification of patients into 3 groups, with groups having 0, 1, and 2 risk factors differing significantly in the prognosis of tumor recurrence (P < 0.001) and overall patient survival (P = 0.006). @*Conclusion@#Both sPD-1 concentration and ADV score have prognostic impacts in patients who underwent LT for untreated HCCs. These factors, both individually and combined, can help in predicting posttransplant prognosis.

ABSTRACT

Purpose@#This study sought to evaluate the clinical effectiveness of the shortening effect of the modified Weil osteotomy for the treatment of Freiberg’s disease. @*Materials and Methods@#We reviewed 21 cases treated with the modified Weil osteotomy for Freiberg’s disease from November 2005 to June 2019. The average follow-up period was 32.5 months and the mean age of the patients was 38.3 years. The clinical results were analyzed using the American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal-interphalangeal scale, the visual analogue scale (VAS), and the range of motion (ROM) of the metatarsophalangeal joint. In the radiologic evaluation, the length of preoperative and postoperative metatarsal shortening was compared. @*Results@#The average AOFAS lesser metatarsophalangeal-interphalangeal scale showed an improvement from 60.5 preoperatively to 90.9 at the latest follow-up. VAS showed a decrease from 5.4 preoperatively to 0.9 at the latest follow-up. ROM of the affected metatarsophalangeal joint increased from 40.2 degrees preoperatively to 58.6 degrees at the latest follow-up. The mean length of metatarsal shortening was 6.7 mm. There was no transfer metatarsalgia, osteonecrosis, and definite joint space narrowing. @*Conclusion@#Modified Weil osteotomy with second layer cutting is an effective treatment option to restore the joint surface and painless joint motion for patients with Freiberg’s disease.

ABSTRACT

Objective@#To assess the feasibility and reproducibility of pancreatic surface lobularity (PSL) quantification derived from abdominal computed tomography (CT) in a population of patients free from pancreatic disease. @*Materials and Methods@#This retrospective study included 265 patients free from pancreatic disease who underwent contrast-enhanced abdominal CT between 2017 and 2019. A maximum of 11 individual PSL measurements were performed by two abdominal radiologists (head [5 measurements], body, and tail [3 measurements each]) using dedicated software.The influence of age, body mass index (BMI), and sex on PSL was assessed using the Pearson correlation and repeated measurements. Inter-reader agreement was assessed using the intraclass correlation coefficient (ICC) and Bland Altman (BA) plots. @*Results@#CT images of 15 (6%) patients could not be analyzed. A total of 2750 measurements were performed in the remaining 250 patients (143 male [57%], mean age 45 years [range, 18–91]), and 2237 (81%) values were obtained in the head 951/1250 (76%), body 609/750 (81%), and tail 677/750 (90%). The mean ± standard deviation PSL was 6.53 ± 1.37. The mean PSL was significantly higher in male than in female (6.89 ± 1.30 vs. 6.06 ± 1.31, respectively, p < 0.001). PSL gradually increased with age (r = 0.32, p < 0.001) and BMI (r = 0.32, p < 0.001). Inter-reader agreement was excellent (ICC 0.82 [95% confidence interval 0.72–0.85], with a BA bias of 0.30 and 95% limits of agreement of -1.29 and 1.89). @*Conclusion@#CT-based PSL quantification is feasible with a high success rate and inter-reader agreement in subjects free from pancreatic disease. Significant variations were observed according to sex, age, and BMI. This study provides a reference for future studies.

ABSTRACT

Calcification in the tendon is a common disease especially in the rotator cuff. The condition can be treated conservatively in the chronic stage, but surgically in the acute stage. On the other hand there are few reports of calcification in the cruciate ligament of the knee joint, especially calcification of the posterior cruciate ligament. A 51-year-old patient with symptomatic calcification in the mid-substance of the posterior cruciate ligament was treated conservatively. The symptoms did not improve after eight months of conservative treatment, so arthroscopic surgery was performed. During arthroscopic removal of the calcification, the ligament was damaged beyond preservation.Eventually a posterior cruciate ligament reconstruction was performed. At two years after surgery, radiography confirmed no recurrence of the calcification, and the patient was free. We report this case study with a review of the relevant literature.

ABSTRACT

Cereblon (CRBN), a negative modulator of AMP-activated protein kinase (AMPK), is highly expressed in the retina. We confirmed the expression of CRBN in ARPE-19 human retinal cells by Western blotting. We also demonstrated that CRBN knock-down (KD) could effectively downregulate IL-6 and MCP-1 protein and gene expression in LPS-stimulated ARPE-19 cells. Additionally, CRBN KD increased the phosphorylation of AMPK/acetyl-coenzyme A carboxylase (ACC) and the expression of heme oxygenase-1 (HO-1) in ARPE-19 cells. Furthermore, CRBN KD significantly reduced LPS-induced nuclear translocation of NF-κB p65 and activation of NF-κB promoter activity. However, these processes could be inactivated by compound C (inhibitor of AMPK) and zinc protoporphyrin-1 (ZnPP-1; inhibitor of HO-1). In conclusion, compound C and ZnPP-1 can rescue LPS-induced levels of proinflammatory cytokines (IL-6 and MCP-1) in CRBN KD ARPE-19 cells. Our data demonstrate that CRBN deficiency negatively regulates proinflammatory cytokines via the activation of AMPK/HO-1 in the retina.

ABSTRACT

BACKGROUND@#Prophylaxis for hepatitis B virus (HBV) recurrence is essential after liver transplantation (LT) in HBV-associated recipients. We conducted real-world analysis of HBV prophylaxis after LT in the Korean population.@*METHODS@#Korean Organ Transplantation Registry (KOTRY) database and additionally collected data (n = 326) were analyzed with special reference to types of HBV prophylaxis.@*RESULTS@#The study cohort comprised 267 cases of living-donor LT and 59 cases of deceased-donor LT. Hepatocellular carcinoma (HCC) was diagnosed in 232 (71.2%) of these subjects. Antiviral agents were used in 255 patients (78.2%) prior to LT. HBV DNA was undetectable in 69 cases (21.2%) and detectable over wide concentrations in the other 257 patients (78.8%) prior to LT. Polymerase chain reaction analysis of the store blood samples detected HBV DNA in all patients, with 159 patients (48.9%) showing concentrations > 100 IU/mL. Post-transplant HBV regimens during the first year included combination therapy in 196 (60.1%), hepatitis B immunoglobulin (HBIG) monotherapy in 121 (37.1%), and antiviral monotherapy in 9 (2.8%). In the second post-transplant year, these regimens had changed to combination therapy in 187 (57.4%), HBIG monotherapy in 112 (34.4%), and antiviral monotherapy in 27 (8.3%). Trough antibody to hepatitis B surface antigen titers > 500 IU/mL and >1,000 IU/mL were observed in 61.7% and 25.2%, respectively. The mean simulative half-life of HBIG was 21.6 ± 4.3 days with a median 17.7 days. Up to 2-year follow-up period, HCC recurrence and HBV recurrence developed in 18 (5.5%) and 6 (1.8%), respectively. HCC recurrence developed in 3 of 6 patients with HBV recurrence.@*CONCLUSION@#Combination therapy is the mainstay of HBV prophylaxis protocols in a majority of Korean LT centers, but HBIG was often administered excessively. Individualized optimization of HBIG treatments using SHL is necessary to adjust the HBIG infusion interval.

ABSTRACT

Purpose@#This study evaluated the results of two groups—the early group and midterm group—comparatively in the treatment of hallux valgus using a scarf osteotomy. @*Materials and Methods@#From January 2005 to December 2009 (Group 1) and from January 2010 to December 2013 (Group 2), this study compared hallux valgus cases treated by a scarf osteotomy by a single surgeon with at least a five-year follow-up. @*Results@#The average ages of Group 1 and Group 2 were 50.5 and 51.7 years old, respectively. The average follow-up of Groups 1 and 2 were 7.4 and 6.2 years, respectively. Groups 1 and 2 had 86 cases (53 patients) and 93 cases (64 patients) with at least a five-year followup, respectively. The average hallux valgus angle (HVA) and 1-2 intermetatarsal angle (IMA) of Group 1 were improved from 31.3° and 13.9° preoperatively to 11.3° and 6.8° at the final follow-up, respectively (p<0.001). The average HVA and 1-2 IMA of Group 2 were improved from 31.7° and 13.4° preoperatively to 8.9° and 6.6° at the final follow-up, respectively (p<0.001). The mean American Orthopaedic Foot and Ankle Society (AOFAS) score of both groups increased from 48.5 and 45.0 points preoperatively to 73.7 and 82.4 points at the final follow-up, respectively. The numbers of patient-assessed subjective satisfaction of Groups 1 and 2 at the final follow-ups were as follows: excellent, 27 and 36 (31.4%, 38.7%); good, 34 and 49 (39.5%, 52.7%); fair, 13 and 5 (15.1%, 5.4%); poor, 12 and 3 (13.9%, 3.2%);respectively. Neither troughing nor stress fractures occurred in both groups. @*Conclusion@#Scarf osteotomy for treating hallux valgus is an excellent surgical method with a relatively low incidence of complications.The results in Group 2 were better than those in Group 1, showing that more surgical experience and evolution of the techniques provided better results.

ABSTRACT

Background@#For volar soft tissue defects of the proximal interphalangeal (PIP) joint, free flaps are technically challenging, but have more esthetic and functional advantages than local or distant flaps. In this study, we compared the long-term surgical outcomes of arterial (hypothenar, thenar, or second toe plantar) and venous free flaps for volar defects of the PIP joint. @*Methods@#This was a single-center retrospective review of free flap coverage of volar defects between the distal interphalangeal and metacarpophalangeal joint from July 2010 to August 2019. Patients with severe crush injuries (degloving, tendon or bone defects, or comminuted/intra-articular fractures), thumb injuries, multiple-joint and finger injuries, dorsal soft tissue defects, and defects >6 cm in length were excluded from the study, as were those lost to follow-up within 6 months. Thirteen patients received arterial (hypothenar, thenar, or second toe plantar) free flaps and 12 received venous free flaps. Patients’ age, follow-up period, PIP joint active range of motion (ROM), extension lag, grip-strength ratio of the injured to the uninjured hand, and Quick Disabilities of Arm, Shoulder & Hand (QuickDASH) score were compared between the groups. @*Results@#Arterial free flaps showed significantly higher PIP joint active ROM (P=0.043) and lower extension lag (P=0.035) than venous free flaps. The differences in flexion, grip strength, and QuickDASH scores were not statistically significant. @*Conclusions@#The surgical outcomes of arterial free flaps were superior to those of venous free flaps for volar defects of the PIP joint.

ABSTRACT

Background@#The introduction of the partial second toe pulp free flap has enabled superior aesthetic and functional results for fingertip reconstruction in adults. Children undergoing fingertip amputation for various reasons have limited options for reconstruction. Conventional treatment could shorten the finger, leading to poor cosmesis and function. We report 18 years of our experiences with fingertip reconstruction using partial second toe pulp free flaps in patients in early childhood. @*Methods@#Medical charts of children who had undergone fingertip reconstruction using partial second toe pulp free flaps from 2001 to 2018 were retrospectively reviewed. The surgical procedures were identical to those for adults, except for the usage of 11-0 nylon sutures. Patients’ demographic data, vessel size, flap dimensions, length of the distal phalanx, and functional outcomes over the course of long-term follow-up were documented. The statistical analysis was performed with the Student t-test, the Mann-Whitney U test, and Pearson correlation analysis. @*Results@#Eighteen toe pulp flaps in 17 patients (mean age, 3.0 years) were identified. All the flaps survived without any major complications. In long-term follow-up, the flap-covered distal phalanges showed growth in line with regular development. There was no donor-site morbidity, and all children adapted to daily life without any problems. In two-point discrimination tests, the fingertip sensation recovered to almost the same level as that in the contralateral finger. @*Conclusions@#Partial second toe pulp free flaps are an excellent option for fingertip reconstruction in young children, as well as in adults.

ABSTRACT

Background@#This study compared clinical outcomes and second-look arthroscopic evaluations between anterior cruciate ligament (ACL) anteromedial (AM) bundle augmentation and single-bundle ACL reconstruction.Purpose: We compared the clinical results and the second-look arthroscopic findings between (1) single-bundle ACL reconstruction in complete rupture and (2) ACL AM bundle augmentation in isolated AM bundle rupture. @*Materials and methods@#Two groups of patients underwent ACL surgery from January 2013 to December 2018. Group 1, who had 64 cases of single-bundle ACL reconstruction with second-look arthroscopy, and Group 2, who had 21 cases of AM bundle augmentation of ACL with second-look arthroscopy, were targeted. We evaluated and compared the clinical results (Lysholm score, Tegner activity score, Lachman test, and pivot-shift test) and synovialization at second-look arthroscopy before the operation and in the final follow-up period, between Group 1 and Group 2. @*Results@#The Lysholm score (p = 0.96) and Tegner activity score (p = 0.351) at final follow-up (mean 27.1 months) were 78.3 and 7.2 in Group 1 and 89.1 and 8.1 in Group 2, respectively. The Lachman test (p = 0.074) and pivot-shift test (p = 0.031) results at final follow-up were improved; however, there was no statistical significance. Second-look arthroscopy showed that percentages of synovialization area of grafted tendon at mean 15.6 months follow-up were 61.4% and 93.1% in Group 1 and Group 2, respectively (p = 0.008). The synovial coverage in Group 2 was higher than in Group 1. @*Conclusion@#The AM bundle augmentation for ACL injury in which the posterolateral bundle was preserved showed better clinical scores and synovial coverage than single-bundle ACL reconstruction for complete ACL rupture.

The synovial coverage in Group 2 was higher than in Group 1. @*Conclusion@#The AM bundle augmentation for ACL injury in which the posterolateral bundle was preserved showed better clinical scores and synovial coverage than single-bundle ACL reconstruction for complete ACL rupture.

ABSTRACT

BACKGROUND/AIMS: Patients with chronic kidney disease (CKD) have a high risk of gastrointestinal tract bleeding because of platelet dysfunction attributable to uremia, a poor blood supply, and frequent use of anticoagulant agents. We describe the colonoscopic characteristics of lower gastrointestinal tract bleeding (LGIB) in patients with CKD. METHODS: A total of 230 hospitalized patients with CKD who underwent colonoscopy because of suspected LGIB between January 2003 and August 2016 were reviewed retrospectively. We categorized CKD into five stages according to the estimated glomerular filtration rate and compared the colonoscopic findings and clinical manifestations among these five subgroups. RESULTS: Of the 230 patients with CKD suspected of LGIB, 73 (31.7%, 103 cases) were colonoscopically confirmed to exhibit LGIB. Their mean age was 65.7 ± 12.8 years, and 52.1% were female (n = 38). The most common causes of LGIB were hemorrhoidal bleeding (32 cases, 43.8%), followed by bleeding of colorectal ulcers (21 cases, 28.8%), diverticular bleeding (12 cases, 16.4%), colitis-related bleeding (12 cases, 16.4%), and angiodysplastic bleeding (12 cases, 16.4%). As the CKD stage progressed, the incidence of LGIB increased (p = 0.043). On multivariate logistic regression analysis, LGIB was more common in CKD patients with hemorrhoids (odds ratio [OR]: 4.349, 95% confidence interval [CI]: 2.043–9.256, p < 0.001) or colorectal ulcers (OR: 20.001, 95% CI: 4.780–83.686, p ℃ 0.001) and in those on hemodialysis (OR: 6.863, 95% CI: 1.140–41.308, p = 0.035). CONCLUSIONS: In CKD patients, the risk of LGIB is significantly increased by hemorrhoids, colorectal ulcers, and a positive hemodialysis status.

ABSTRACT

BACKGROUND: Underweight is associated with increased mortality, relative to the normal weight category. The importance of managing underweight patients has not yet been recognized seriously in South Korea, and little information is available on the prevalence of underweight and its associated risk factors. This study aims to investigate changes in the prevalence of underweight by gender and age and analyze its trend.METHODS: Data were obtained from individuals aged >20 years, from the Korean National Health and Nutrition Examination Survey between 1995 and 2015. The subjects of this study included 134,613 adults (male, 61,152; female, 73,461). The prevalence of underweight was determined as defined by the Asia-Pacific Perspective, and socioeconomic factors associated with a predisposition to underweight were analyzed using the chi-squared test and multiple logistic regression analysis.RESULTS: Among Korean adults, the age-adjusted prevalence of underweight (body mass index < 18.5 kg/m²) was 3.1% in men and 6.3% in women. Overall, a U-shaped relationship was established between the prevalence of underweight by gender and age. There was no significant difference in socioeconomic factors related to the prevalence of underweight in men and women in their twenties. The prevalence of underweight in women aged 20–59 years showed an increasing trend (P for trends < 0.05).CONCLUSION: In individuals aged 20–29 years, the prevalence of being underweight was higher in women than in men. Recently, there has been an increasing trend in the prevalence of underweight young women of reproductive age. This requires national public health attention.
