Low muscle density in children with osteogenesis imperfecta using opportunistic low-dose chest CT: a case-control study.

BACKGROUND: The aim of the study was to investigate the muscle differences in children with osteogenesis imperfecta (OI) using opportunistic low-dose chest CT and to compare different methods for the segmentation of muscle in children. METHODS: This single center retrospective study enrolled children with OI and controls undergoing opportunistic low-dose chest CT obtained during the COVID pandemic. From the CT images, muscle size (cross-sectional area) and density (mean Hounsfield Units [HU]) of the trunk muscles were measured at the mid-T4 and the mid-T10 level using two methods, the fixed thresholds and the Gaussian mixture model. The Bland-Altman method was also used to compute the strength of agreement between two methods. Comparison of muscle results between OI and controls were analyzed with Student t tests. RESULTS: 20 children with OI (mean age, 9.1 ± 3.3 years, 15 males) and 40 age- and sex-matched controls were enrolled. Mean differences between two methods were good. Children with OI had lower T4 and T10 muscle density than controls measured by the fixed thresholds (41.2 HU vs. 48.0 HU, p < 0.01; 37.3 HU vs. 45.9 HU, p < 0.01). However, children with OI had lower T4 muscle size, T4 muscle density, T10 muscle size and T10 muscle density than controls measured by the Gaussian mixture model (110.9 vs. 127.2 cm2, p = 0.03; 44.6 HU vs. 51.3 HU, p < 0.01; 72.6 vs. 88.0 cm2, p = 0.01; 41.6 HU vs. 50.3 HU, p < 0.01, respectively). CONCLUSIONS: Children with OI had lower trunk muscle density indicating that OI might also impair muscle quality. Moreover, the fixed thresholds may not be suitable for segmentation of muscle in children.

Association of Low Back Pain with Shift Work: A Meta-Analysis.

Shift work (SW) is the main working schedule worldwide, and it may cause sleep disorders, breast cancer, and cardiovascular disease. Low back pain (LBP) is a common problem in the workplace; however, the association between LBP and SW remains unclear. Therefore, we conducted a meta-analysis to determine the association between SW and LBP. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed, Embase, and Web of Science databases using a set of associated keywords were queried. The inclusion criteria were as follows: (1) adult employees hired by a company or organization; (2) SW exposure; and (3) the outcome of LBP according to examination or assessment. A total of 40 studies were included that met the inclusion criteria for the meta-analysis. SW was significantly associated with LBP (odds ratio [OR]: 1.31, 95% confidence interval [CI]: 1.18−1.47, p < 0.00001). Furthermore, it was observed that LBP was significantly associated with night shift (NS) (OR: 1.49, 95% CI: 1.24−1.82, p < 0.0001) but not with rotating shift (RS) (OR: 0.96, 95% CI: 0.76−1.22, p = 0.49). Moreover, LBP was significantly associated with SW in health care workers (HCWs) (OR: 1.40, 95% CI: 1.20−1.63, p < 0.0001) but not in non-HCWs (OR: 1.19, 95% CI: 0.94−1.50, p = 0.14). SW was significantly associated with LBP. Furthermore, the subgroup analysis showed that NS, but not RS, was associated with LBP. Compared with SW in non-HCWs, SW in HCWs was significantly associated with LBP.

Symptomatic Bunionette Treated with Sliding Oblique Metatarsal Osteotomy-Case Series.

Background: The purpose of this study is to investigate the clinical and radiological results of a sliding oblique metatarsal osteotomy (SOMO) to correct bunionette deformity. Methods: We retrospectively reviewed 44 patients (51 feet, left/right: 29/22) from December 2010 to December 2018 who underwent SOMO and compared radiographic measurements and clinical outcome scores preoperatively and postoperatively. Radiographic measurements included 4th and 5th intermetatarsal angle (IMA), metatarsophalangeal angle (MTPA), and lateral deviation angle (LDA). Clinical outcome measurements included The American Orthopedic Foot and Ankle Society (AOFAS) score for lesser metatarsophalangeal procedures and visual analog scale (VAS) pain score. The mean follow-up period was 26.6 months (minimum 18 months). Based on Coughlin and Fallat classification, all cases were separated into four subtypes: 6 type I, 10 type II, 12 type III, 23 type IV cases included.) Results: All radiographic parameters significantly improved after SOMO procedure (IMA/MTPA/LDA, p value < 0.001). Clinical scores also showed a significant improvement in AOFAS and VAS scores (p value < 0.001). In terms of subgroup based on each type, both radiographic measurements and clinical scores revealed significant improvements in each subgroup (p value < 0.05), except LDA of type I subgroup (p value = 0.09). Three cases reported pin-tract infection but recovered with good healing after removal of the K-wire and a prescription of oral antibiotic. Conclusion: The SOMO procedure may be considered as a reliable and simple treatment for most types of bunionette deformity with satisfactory outcomes and no severe complications. Level of Evidence: Level IV, case series.

Effect of the traditional Chinese herb Helminthostachys zeylanica on postsurgical recovery in patients with ankle fracture: A double-blinded randomized controlled clinical trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Helminthostachys zeylanica (HZ), which is also called "Dao-Di-U-Gon" in Taiwan, has anti-inflammatory and antiedema effects and is commonly used to treat edema in patients with fractures. The ugonin K component of HZ can induce osteogenesis and promote bone mineralization, its therapeutic effect, however, its therapeutic effect remains unclear. Therefore, the purpose of the present study was to investigate the effect of HZ on functional recovery in patients with ankle fractures requiring surgical treatment. METHODS: A double-blinded, randomized, controlled study was conducted. A total of 45 patients with ankle fractures requiring surgical treatment were assigned to either the control group (n = 23 patients), which received the oral administration of HZ placebo 1.0 g t.i.d. for 42 days continuously, or to the treatment group (22 patients), which received HZ for 42 days. RESULTS: The serum amino-terminal propeptide of type 1 procollagen (PINP) levels were similar in the first assessment (V1) between the control (45.90 ± 16.31 ng/mL) and treatment groups (52.61 ± 21.02 ng/mL; p = 0.240); the differences in PINP level between the third assessment (V3) and V1 were greater in the treatment group (35.84 ± 24.56 ng/mL) than in the control group (16.34 ± 11.97 ng/mL; p = 0.002). Radiographic healing time (RHT) was 9.09 ± 1.15 weeks in the treatment group, which was shorter than the 9.91 ± 0.79 weeks (p = 0.012) in the control group. CONCLUSION: Oral administration of HZ for 42 days can increase serum PINP level and reduce the RHT. Therefore, HZ can be used to treat patients with ankle fractures requiring surgical treatment. However, a larger sample size is needed in future studies.

Syndesmosis Changes before and after Syndesmotic Screw Removal: A Retrospective Radiographic Study.

BACKGROUND AND OBJECTIVES: In patients with ankle fractures complicated by syndesmotic injuries, no consensus has been reached on the best method of syndesmosis fixation using syndesmotic screws. One previous study revealed no difference in the tibiofibular overlap between two groups with or without syndesmotic screw removal. Other studies have indicated that distal tibiofibular diastasis exists after the removal of syndesmotic screws. In this study, we aimed to confirm the effect of syndesmotic screw removal on diastasis occurrence. We further analyzed the risk factors that may contribute to the widening of the tibiofibular syndesmosis. MATERIALS AND METHODS: This retrospective study involved a review of the records of 63 patients with ankle fractures accompanied by syndesmosis injuries that required syndesmotic screw fixation. Anteroposterior radiographs were analyzed for each patient at various time points, from syndesmotic screw fixation to outpatient department follow-ups after screw removal. The changes in tibia-fibula overlap (OL), tibia-fibula clear space (CS), and medial clear space (MCS) were analyzed. Further analysis was performed to reveal potential factors that may have contributed to radiographic differences. RESULTS: Compared with the postoperation radiographs following syndesmotic screw fixation, OL decreased (2.0 mm) and CS increased (0.8 mm) in the anteroposterior radiographs from outpatient department follow-ups. No significant changes were noted in OL or CS after syndesmotic screw removal. However, OL decreased (1.8 mm) and CS increased (0.5 mm) before syndesmotic screw removal. No significant change in MCS occurred during the whole observation period. Linear regression analysis did not reveal any significant correlations between potentially related factors and radiographic changes. CONCLUSIONS: Marked diastasis had occurred at final follow-up. Notably, the diastasis occurred before rather than after screw removal. This implies that screw removal does not significantly influence the radiographic outcomes of rotational ankle fractures.

A versatile method for dorsal-approach plantar plate repair using standard operative instruments.

BACKGROUND: The plantar plate is an important static stabilizer of the lesser metatarsophalangeal joints, and disruptions of the plantar plate can lead to significant instability and lesser toe deformities. In recent years, direct plantar plate repair has been proposed. Although direct repair via a dorsal approach is attractive, a torn plantar plate is small and difficult to access using regular instruments in a restricted operative field. METHODS: In this report, a unique method for plantar plate repairs was used to repair various configurations of plantar plate tears with standard operative instruments that are available in most operating rooms. RESULTS: Using this method, 10 patients underwent plantar plate repairs, and the mean follow-up period was 24 (range, 14-38) months. The mean visual analog scale score for pain preoperatively was 4.1 (range, 0-6) and decreased to 0.6 (range, 0-3) at last follow-up. Postoperatively, the mean visual analog scale score for satisfaction was 9.6 (range, 8-10) and the mean American Orthopedic Foot and Ankle Society forefoot score was 88.8 (range, 75-100). CONCLUSIONS: Our study proposes an inexpensive and versatile method for plantar plate repair via a dorsal approach that uses standard operative instruments.

Shockwave Treatment Enhanced Extracellular Matrix Production in Articular Chondrocytes Through Activation of the ROS/MAPK/Nrf2 Signaling Pathway.

OBJECTIVE: Shockwave application is a potential treatment for osteoarthritis (OA), but the underlying mechanism remains unknown. Oxidative stress and a counterbalancing antioxidant system might be the key to understanding this mechanism. We hypothesized that reactive oxygen species (ROS) and the transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2),which is an important regulator of cellular redox homeostasis, are plausible elements. DESIGN: Porcine chondrocytes were cultured in a 3-dimensional pellet model and subjected to shockwaves. The effects of shockwaves with various energy-flux densities on optimal extracellular matrix (ECM) synthesis were assessed. ROS, mitogen-activated protein kinase (MAPK) signaling, and the redox activity of Nrf2 were measured. To investigate the signaling mechanism involved in the shockwave treatment in chondrocytes, specific inhibitors of ROS, MAPK signaling, and Nrf2 activity were targeted. RESULTS: Shockwaves increased ECM synthesis without affecting cell viability or proliferation. Furthermore, they induced transient ROS production mainly through xanthine oxidase. The phosphorylation of ERK1/2 and p38 and the nuclear translocation of Nrf2 were activated by shockwaves. By contrast, suppression of ROS signaling mitigated shockwave-induced MAPK phosphorylation, Nrf2 nuclear translocation, and ECM synthesis. Pretreatment of chondrocytes with the specific inhibitors of MEK1/2 and p38, respectively, mitigated the shockwave-induced nuclear translocation of Nrf2 and ECM synthesis. Nrf2 inhibition by both small hairpin RNA knockdown and brusatol reduced the shockwave-enhanced ECM synthesis. CONCLUSIONS: Shockwaves activated Nrf2 activity through the induction of transient ROS signaling and subsequently enhanced ECM synthesis in chondrocytes. This study provided fundamental evidence confirming the potential of shockwaves for OA management.

Comparison of Efficacy among Three Radiofrequency Ablation Techniques for Treating Knee Osteoarthritis: A Systematic Review and Meta-Analysis.

Radiofrequency ablation (RFA) was first introduced for treating knee osteoarthritis (OA) in 2010 and has emerged as a minimally invasive treatment option. Three RFA techniques have been adopted for treating knee OA, including conventional, pulsed, and cooled RFA. However, the efficacy among different RFA techniques in the treatment of knee OA is still unclear. Three electronic databases were systematically searched for relevant articles, including PubMed, Embase, and Cochrane Library. A meta-analysis of articles that investigated the use of RFA techniques in the treatment of knee OA was conducted to pool the effect size in pain before and after treatment. A total of 20 eligible articles (including 605 patients) were included for our meta-analysis. After treatment, the patients had significant improvements in pain for all three RFA techniques when compared with the baseline level for the 1, 3-, and 6-month follow-ups (p < 0.00001). However, there were no significant differences in the efficacy among the three RFA techniques for all follow-up visits (p > 0.05). The three RFA techniques demonstrated a significant improvement in pain for up to 6 months after treatment. Comparing the efficacy of the three RFA techniques in the treatment of knee OA, our results showed that no significant differences in pain relief among the three RFA techniques were observed at the 1-, 3-, 6, and 12-month follow-up visits.

Application of microRNA in Human Osteoporosis and Fragility Fracture: A Systemic Review of Literatures.

MicroRNAs (miRNAs) could serve as ideal entry points to the deregulated pathways in osteoporosis due to their relatively simple upstream and downstream relationships with other molecules in the signaling cascades. Our study aimed to give a comprehensive review of the already identified miRNAs in osteoporosis from human blood samples and provide useful information for their clinical application. A systematic literature search for relevant studies was conducted in the Pubmed database from inception to December 2020. We set two essential inclusion criteria: human blood sampling and design of controlled studies. We sorted the results of analysis on human blood samples according to the study settings and compiled the most promising miRNAs with analyzed diagnostic values. Furthermore, in vitro and in vivo evidence for the mechanisms of the identified miRNAs was also illustrated. Based on both diagnostic value and evidence of mechanism from in vitro and in vivo experiments, miR-23b-3p, miR-140-3p, miR-300, miR-155-5p, miR-208a-3p, and miR-637 were preferred candidates in diagnostic panels and as therapeutic agents. Further studies are needed to build sound foundations for the clinical usage of miRNAs in osteoporosis.

Hemoglobin A1c Levels Associated with Age and Gender in Taiwanese Adults without Prior Diagnosis with Diabetes.

Several studies have reported that Hemoglobin A1c (HbA1c) levels increase with age for people without diabetes. However, HbA1c levels associated with age and gender have not been well investigated for Taiwanese adults. The objective of this study was to investigate the sex-specific association between HbA1c levels and age for Taiwanese adults without diabetes. The data were collected from the Taiwan Biobank database with inclusive criteria being participants without diabetes. The association between HbA1c values and age was conducted by linear regression analysis, HbA1c values between sexes were compared by two-sample t-test, and HbA1c levels among age groups were compared using one-way ANOVA. The results showed that HbA1c levels were positively correlated with age, and the levels for males were significantly higher than for females among all participants. However, there was no significantly positive correlation between HbA1c levels and age in males for age group of 50-70 years. The levels of males were significantly higher than females for age groups of 30-39 and 40-49 years. There were significant differences in HbA1c levels among age groups for all participants, males, and females except for the two age groups of 50-59 and 60-70 years in males. Age and gender were important factors affecting HbA1c levels. Our results suggested that the HbA1c cut-point levels for the diagnosis of diabetes should vary by age and gender.

Impact of the COVID-19 pandemic and its related psychological effect on orthopedic surgeries conducted in different types of hospitals in Taiwan.

AIM: Taiwan's response to the coronavirus disease 2019 (COVID-19) differed in that it successfully prevented the spread without having to shutdown or overburden medical services. Patients' fear regarding the pandemic would be the only reason to reduce surgeries, so Taiwan could be the most suitable place for research on the influence of psychological factors. This study aimed to assess the impact of patients' fear on orthopedic surgeries in Taiwan amid the peak period of the COVID-19 pandemic. PATIENTS AND METHODS: The investigation period included the COVID-19 pandemic (March 2020 to April 2020) and the corresponding period in the previous year. The following data on patients with orthopedic diseases were collected: outpatient visits, hospital admission, and surgical modalities. RESULTS: The COVID-19 pandemic led to a 22%-29% and 20%-26% reduction in outpatients, 22%-27% and 25%-37% reduction in admissions, and 26%-35% and 18%-34% reduction in surgeries, respectively, at both hospitals. The weekly mean number of patients was significantly smaller during the COVID-19 pandemic for all types of surgery and elective surgeries at the university hospital, and for all types of surgery, elective surgeries, and total knee arthroplasties at the community hospital. Further, patients visiting the community hospital during the pandemic were significantly younger, for all types of surgery, elective surgeries, and total knee arthroplasties. CONCLUSIONS: The reduction in orthopedic surgeries in Taiwan's hospitals during COVID-19 could be attributed to patients' fear. Even without restriction, the pandemic inevitably led to a reduction of about 20%-30% of the operation volume.

Clinical Outcomes of Total Ankle Arthroplasty Versus Ankle Arthrodesis for the Treatment of End-Stage Ankle Arthritis in the Last Decade: a Systematic Review and Meta-analysis.

Ankle arthrodesis (AA) and total ankle arthroplasty (TAA) are the 2 primary surgical treatments for patients with end-stage ankle arthritis. The comparative outcomes between AA and TAA using modern techniques remain unclear. A systematic search to identify all relevant articles comparing AA with TAA was conducted through 3 online databases. The clinical outcomes were extracted for meta-analysis, including AOFAS (American Orthopaedic Foot & Ankle Society) score, VAS (visual analog scale), AOS (Ankle Osteoarthritis Scale), gait analysis, ROM (range of motion), satisfaction, complication, and reoperation. Our meta-analysis shows no heterogeneity in any subgroup analyses. There were no significant differences in AOFAS total, pain, and alignment scores between the AA and TAA groups. The TAA group had significant improvement in AOFAS function score compared with the AA group. There was no significant difference in VAS and AOS total scores between the 2 groups. No significant differences in gait analysis were observed between the 2 groups. The TAA group had significant improvement in both ROM and change in ROM compared with the AA group. There was no significant difference in satisfaction rate between the 2 groups. The TAA group had significantly higher complication and reoperation rates compared with the AA group. Our meta-analysis provides updated evidence on clinical outcomes comparing AA with TAA using third-generation implants. The TAA group had better improvement in AOFAS function and ROM than the AA group. No significant differences in pain relief, gait analysis, or patient satisfaction were observed between the 2 groups.

Comparative effectiveness of various treatment strategies for trigger finger by pairwise meta-analysis.

OBJECTIVE: To compare the efficacy of various strategies in the treatment of trigger finger. DATA SOURCES: A systematic literature search for randomized controlled trials to compare treatments for trigger finger was conducted through three online databases, Pubmed, Embase and Cochrane Library, from their inception dates to 22 May 2020. METHODS: Relative risk (RR) with 95% confidence interval (CI) was used to evaluate the effect sizes in success rate for included articles. RESULTS: Sixteen articles (n = 1185) were included in our meta-analysis. The results showed that the efficacy of steroid injection was significantly better than the placebo group at short-term follow-ups (RR = 19.00, 95% CI = 1.17-309.77 for one-week; RR = 3.70, 95% CI = 3.70, 95% CI = 1.61-8.53 for one-month), and then became non-significant at four months (RR = 3.21, 95% CI = 0.88-11.79). There was no significant difference in success rate between steroid injection and nonsteroidal anti-inflammatory drug injection, and between open surgery and percutaneous release at all the follow-ups. Only surgical treatment had significantly better efficacy in success rate than steroid injection at all follow-ups (RR = 0.48, 95% CI = 0.34-0.66 for one-month; RR = 0.87, 95% CI = 0.80-0.96 for three-month; RR = 0.58, 95% CI = 0.48-0.68 for six-month; RR = 0.38, 95% CI = 0.20-0.72 for 12-month). CONCLUSION: There were no differences in efficacy between steroid injection and shockwave or nonsteroidal anti-inflammatory drug injection. The surgical treatments had the best efficacy among these treatments.

A comparison of efficacy among different radiofrequency ablation techniques for the treatment of lumbar facet joint and sacroiliac joint pain: A systematic review and meta-analysis.

OBJECTIVE: To compare the efficacy of different radiofrequency techniques (thermal, pulsed, and cooled radiofrequency) for treating lumbar facet joint (LFJ) or sacroiliac joint (SIJ) pain. PATIENTS AND METHODS: The inclusion criteria were as follows: (1) age > 18 years; (2) patients suffering from LFJ or SIJ pain; and (3) patients receiving radiofrequency treatments. Four electronic databases, including Pubmed, Embase, Cochrane Library, and ISI Web of Knowledge were systematically searched from inception until December 2019 for relevant articles. The search was conducted on 2 January 2020. When the outcomes among articles showed heterogeneity, then a random-effects model was adopted to calculate the effect size; otherwise, a fixed-effects model was adopted. RESULTS: All the three techniques showed significant improvements in LFJ or SIJ pain for up to 12 months compared with the baseline level. However, no significant differences among the three techniques were observed at any follow-up visits except for possibly a trend for variance in efficacy. For treating LFJ pain, cooled radiofrequency was the most effective, followed by thermal radiofrequency and then pulsed radiofrequency as the least respectively for the follow-up visit at 6 months. No serious complications were reported after receiving treatment using the three techniques. CONCLUSION: Sequentially, cooled radiofrequency followed by thermal radiofrequency and then pulsed radiofrequency for treating LFJ pain were identified as most to least effective at the 6-month follow-up.

Management of nonunion of humeral medial condyle fracture: A case series and review of the literature.

Pediatric humeral medial condyle fracture (HMCF) is a rare condition and is difficult to detect, especially in young children. The management of late presentation of HMCF is challenging and lacks consensus. Herein, we reported four cases of HMCF nonunion received open reduction and internal fixation (ORIF) or supracondyle osteotomy from our institution. In addition, 12 cases of ORIF and 4 cases of osteotomy reported in the previous studies were also reviewed. The HMCF nonunion can heal after ORIF, but the indication and the optimal techniques need to be clarified. Supracondylar osteotomy alone is an effective and safe treatment option to improve the functional and cosmetic outcomes of HMCF nonunion.

Contracture of extensor hallucis longus after fracture of distal tibia and fibula: A case report.

Post-traumatic isolated big toe extensor contracture after tibiofibular fracture is uncommon and only a few cases have been reported. Major causes of it include anterior compartment syndrome, direct injury, entrapment or adhesion of the muscle or tendon.We present an uncommon case of isolated extensor hallucis longus (EHL) tendon contracture following a distal tibiofibular shaft fracture without compartment syndrome of the affected leg or foot. The clinical outcome is good after Z-lengthening of the EHL tendon and abductor hallux tendon in 1-year follow-up. LEVEL OF CLINICAL EVIDENCE: 5.

Efficacy and Safety of Extracorporeal Shockwave Therapy for Treatment of Knee Osteoarthritis: A Systematic Review and Meta-analysis.

OBJECTIVE: The objective of this study was to assess the efficacy and safety of extracorporeal shockwave therapy (ESWT) for treatment of knee osteoarthritis (OA) using a systemic review and meta-analysis. METHODS: An extensive search of relevant articles from electronic databases Pubmed, Embase, and Cochrane Library from inception to March 2019 was conducted. The treatment outcomes (visual analog scale [VAS] and the Western Ontario and McMaster Universities Arthritis Index [WOMAC]) of the included articles were pooled to calculate effect sizes. The assessment of heterogeneity among articles was evaluated using I2. Statistical analyses were conducted using RevMan software. RESULTS: The results showed that the ESWT group had significant improvement in pain relief compared with the control group through 12 months based on WOMAC and VAS scores. Compared with the baseline level, the patients had significant improvement in pain relief at most follow-up points (one week to 12 months) based on WOMAC and VAS scores. The patients showed significant improvement in physical function at six- and 12-month follow-up when compared with the control group and for all follow-up (one to 12 months) when compared with the baseline level. Additionally, only minor complications were observed after ESWT treatment. CONCLUSIONS: The use of ESWT for treatment of knee OA had a beneficial effect on pain relief and physical function improvement for up to 12 months, and only minor complications occurred after ESWT treatment. However, there remains a lack of clarity regarding the frequency and dosage levels of ESWT required to achieve the maximum improvement.

Impact of orthogeriatric care, comorbidity, and complication on 1-year mortality in surgical hip fracture patients: An observational study.

After acute hip surgery, the 1-year mortality rate is high. Therefore, this study evaluated the risk factors for 1-year mortality. The purposes of this study was first to examine the effect of integrated care on 1-year mortality in surgical patients and secondly to explore magnitude of comorbidity and complication on mortality.This retrospective cohort study included 313 patients received surgery for hip fragility fracture. Patients with multiple fractures or combined trauma were excluded. The patients were grouping into integrated (n = 106) and non-integrated care group (n = 207) models. Univariate and multiple Cox regression were used to examine effect of care model, comorbidity, and complication event.One-year mortality in integrated and non-integrated patients was 4.7% and 14.0% respectively. After adjustments, patients in non-integrated care, have 2.89 times (95% confidence interval [CI] 1.07-7.81) likely to die 1-year after discharged.Patients had elevated comorbidity or postoperative complications contributed to the mortality. Our study found the effect of patients treated by integrated care models, compared with usual model, significantly reduced 1-year mortality rate. Appropriated treatment of comorbidities during hospitalization and after discharge is critical to post-surgical survival. The findings imply that the co-care for hip fracture of hip surgical patients with orthogeriatricians is strongly recommended, particularly for those with >3 comorbidities.

Efficacy of Different Energy Levels Used in Focused and Radial Extracorporeal Shockwave Therapy in the Treatment of Plantar Fasciitis: A Meta-Analysis of Randomized Placebo-Controlled Trials.

The objective of this study was to assess the efficacy of different energy levels used in extracorporeal shockwave therapy (ESWT) in the treatment of plantar fasciitis using a systematic review and meta-analysis. We searched PubMed, Embase, and Cochrane library, from inception to March 2019 for randomized controlled trials that compared ESWT with placebo in patients with plantar fasciitis. The risk of bias for selected articles was assessed based on the Cochrane Handbook Systematic Review of Interventions. The pooled data were estimated by the mean difference or odds ratio. The meta-analysis showed that the high-energy ESWT group had a better success rate than the control group only at a three-month follow-up, but no significant difference between groups was observed for the other follow-up visits (1 and 12 months). In addition, no significant differences in visual analog scale (VAS) scores between groups were observed for all the follow-up visits (one-month and three-month). On the contrary, the medium-energy ESWT group had significantly better success rates than the control group for all the follow-up visits (3, 6, and 12 months). In addition, the medium-energy ESWT group had significant improvement in VAS scores compared with the control group for all the follow-up visits (1, 3, 6, and 12 months) after removing the extreme values. The low-energy ESWT group had significant improvement in VAS scores compared with the control group for all the follow-up visits (3 and 12 months). Otherwise, focused ESWT seems to be more effective than radial ESWT when compared with the control group. Use of local anesthesia can reduce the efficacy of low- and high-energy ESWTs. Our meta-analysis suggested that medium-energy ESWT in the treatment of plantar fasciitis was more effective than the control group. A limited number of trials related to low- and high-energy ESWTs were included in our meta-analysis. More research is required to confirm the efficacy of low- and high-energy ESWTs in future studies.
