ABSTRACT
OBJECTIVE: This study aimed to evaluate the short-term and long-term efficacy of Mongolian medical warm acupuncture for sciatica caused by lumbar disc herniation (LDH). PATIENTS AND METHODS: The patients diagnosed with sciatica caused by LDH were randomly divided into the warm acupuncture of the Mongolian medicine group (n = 42, warm acupuncture treatment), the sham acupuncture group (n = 38, sham acupuncture using blunt-tipped needles) and the conventional drug group (n = 40, ibuprofen sustained release capsule). All patients were treated for 4 weeks and followed up for 8 weeks. The visual analog scale for leg pain (VAS-LP), Mongolian medicine indicators (efficacy indicators), VAS for waist pain (VAS-WP) and the Mos 36-item short form health survey (SF-36) score were analyzed at baseline, after two-week treatment, after four-week treatment, at four-week follow-up and at eight-week follow-up. RESULTS: Warm acupuncture treatment significantly decreased the VAS-LP and VAS-WP scores of patients at treatment and follow-up (p < 0.05), and pain was improved compared to the conventional drug group and sham acupuncture group. The total effective rate was markedly higher in the warm acupuncture of the Mongolian medicine group compared with the conventional drug group at 8-week follow-up (p < 0.05), but sham acupuncture treatment resulted in no evident improvement in the Mongolian medicine indicators. Additionally, at treatment and follow-up, warm acupuncture of the Mongolian medicine group showed a significant increase in the physical function, physical role, body pain, and emotional and mental health role scores of the SF-36 survey compared with the sham acupuncture groups. CONCLUSIONS: Mongolian medical warm acupuncture effectively relieves leg and waist pain and improves the total therapeutic effect and the quality of daily life for patients with sciatica caused by LDH, with significant long-term efficacy. Our study provides a basis for warm acupuncture in the treatment of sciatica caused by LDH. Chinese Clinical Trial Registry ID: ChiCTR- INR-15007413.

Fracture liaison services (FLS) have been proven clinically effective and cost-effective in preventing subsequent fractures among patients with an existing fragility fracture. Little is known about their monetary benefits such as their return on investment (ROI). This systematic review aimed to investigate the ROI of FLS and identify the FLS characteristics with better ROI. Studies on the cost-effectiveness of FLS published between January 2000 and December 2022 were searched from MEDLINE, EMBASE, PubMed, and Cochrane Central. Two independent reviewers conducted study selection and data extraction. ROI was calculated based on the difference between monetary benefits and FLS costs divided by the FLS costs. Subgroup analysis of ROI was performed across FLS types and FLS design details. A total of 23 FLS were included in this review. The majority of them were targeting patients aged over 50 years having fractures without identified sites. The mean ROI of these FLS was 10.49 (with a median ROI of 7.57), and 86.96% of FLS had positive ROI. FLS making treatment recommendations yielded the highest ROI (with a mean ROI of 18.39 and a median of 13.60). Incorporating primary care providers (with a mean ROI of 16.04 and a median of 13.20) or having them as program leaders (with a mean ROI of 12.07 and a median of 12.07) has demonstrated a high ROI. FLS for specific fracture sites had great monetary return. Intensive FLS such as type A and B FLS programs had higher ROI than non-intensive type C and D FLS. This review revealed a 10.49-fold monetary return of FLS. Identified characteristics contributing to greater economic return informed value-for-money FLS designs. Findings highlight the importance of FLS and the feasibility of expanding their contribution in mitigating the economic burden of osteoporotic fracture and are conducive to the promotion of FLS internationally.

BACKGROUND: The outcome of patients with resectable mucosal melanoma is poor. Toripalimab combined with axitinib has shown impressive results in metastatic mucosal melanoma with an objective response rate of 48.3% and a median progression-free survival of 7.5 months in a phase Ib trial. It was hypothesized that this combination administered in the neoadjuvant setting might induce a pathologic response in resectable mucosal melanoma, so we conducted this trial. PATIENTS AND METHODS: This single-arm phase II trial enrolled patients with resectable mucosal melanoma. Patients received toripalimab 3 mg/kg once every 2 weeks (Q2W) plus axitinib 5 mg two times a day (b.i.d.) for 8 weeks as neoadjuvant therapy, then surgery and adjuvant toripalimab 3 mg/kg Q2W starting 2 ± 1weeks after surgery for 44 weeks. The primary endpoint was the pathologic response rate according to the International Neoadjuvant Melanoma Consortium recommendations. RESULTS: Between August 2019 and October 2021, 29 patients were enrolled and received treatment, of whom 24 underwent resection. The median follow-up time was 34.2 months (95% confidence interval 20.4-48.0 months). The pathologic response rate was 33.3% (8/24; 4 pathological complete responses and 4 pathological partial responses). The median event-free survival for all patients was 11.1 months (95% confidence interval 5.3-16.9 months). The median overall survival was not reached. Neoadjuvant therapy was tolerable with 8 (27.5%) grade 3-4 treatment-related adverse events and no treatment-related deaths. Tissue samples of 17 patients at baseline and after surgery were collected (5 responders and 12 nonresponders). Multiplex immunohistochemistry demonstrated a significant increase in CD3+ (P = 0.0032) and CD3+CD8+ (P = 0.0038) tumor-infiltrating lymphocytes after neoadjuvant therapy, particularly in pathological responders. CONCLUSIONS: Neoadjuvant toripalimab combined with axitinib in resectable mucosal melanoma demonstrated a promising pathologic response rate with significantly increased infiltrating CD3+ and CD3+CD8+ T cells after therapy.

Upper eyelid aging with lateral hooding is common among Asian women older than 40 years. Since Asians tend to develop more visible scars than White people, we used an extended upper blepharoplasty technique to correct lateral hooding and conceal the scar, combined with the removal of the thick subbrow skin for women over 60 years of age, to achieve a stable, improved outcome. An extended cutaneous scalpel-shaped excision was designed and hid the extended part of the excision in the patient's upward crow's feet to address the redundant skin of lateral hooding. For patients older than 60 years, we used a crescent-shaped excision and simultaneously removed the thick skin under the eyebrow to reduce the likelihood of long-term postoperative pseudoexcess. A retrospective study was conducted on 40 Asian women who underwent upper eyelid rejuvenation surgery with the above methods from July 2020 to March 2021 (follow-up, 12-15 mo). Extended blepharoplasty notably corrected the lateral hooding and achieved a natural double eyelid. The postoperative scar was inconspicuous. For patients older than 60 years, the long-term rejuvenation outcome was stable when associated with subbrow skin removal. However, two patients older than 60 years in whom the subbrow skin was not removed developed pseudoexcess of the upper eyelid 1 year postoperatively. Extended blepharoplasty is a simple and effective technique for improving periorbital aging in Asian women, and the postoperative scarring was inconspicuous. For patients older than 60 years, we recommend removal of the thick subbrow skin to avoid long-term postoperative pseudoexcess.

Objective: To investigate the spontaneous nystagmus (SN) and the frequency characteristics of affected semicircular canals in patients with vestibular neuritis (VN). Methods: This is a cross-sectional study. A total of 61 patients with VN admitted to the Department of Neurology of Shanxi Bethune Hospital from June 2020 to October 2021, 39 were male and 22 were female, with a mean age of (46±13) years old and male to female ratio of 1.77â¶1. According to SN characteristics, 61 patients were divided into non-nystagmus group(nSN), horizontal nystagmus group(hSN) and horizontal-torsional nystagmus group (htSN). Clinical data were collected, and SN, unilateral weakness (UW), directional preponderance (DP), and video head impulse test (vHIT) gain were used as observation indicators. Statistical analysis by SPSS23.0 software. Normal distributed quantitative data (age, semicircular canal gain, SN intensity) were expressed by x¯±s, non-normal distributed quantitative data (disease course, UW, DP) were expressed by M(Q1,Q3), qualitative data were expressed by rate and composition ratio, difference analysis by one-way ANOVA, rank sum test, Chi-square test or Fisher's exact probability method, considered by P value<0.05. Results: (1)The disease course of nSN, hSN and htSN was 7.0 (4.0, 12.5), 6.0 (3.5, 11.5), and 3.0 (2.0, 6.5) days respectively, and there were statistical differences (χ2=7.31,P=0.026).(2)The horizontal nystagmus intensity of htSN was (16.8±8.6)°/s, which was significantly higher than that of (9.8±4.7)°/s in hSN (t=3.71, P<0.001). There was no significant difference in the positive rate of UW between the three groups (P=0.690), and there was a significant difference in the positive rate of DP in the three groups (χ2=12.23, P=0.002). The horizontal nystagmor intensity in the htSN was positively correlated with the vertical nystagmus intensity (r=0.59, P=0.001).(3)The gain of the affected horizontal canal of the three groups was statistically different (F=8.28, P=0.001), and the gain of the horizontal canal of hSN and htSN was significantly lower than that of nSN (t=2.74, P=0.008; t=4.05, P<0.001); The gain of the affected anterior canal in the three groups was statistically different (F=5.32, P=0.008). The gain of the anterior canal in both nSN and hSN was significantly higher than that in htSN (t=3.09, P=0.003; t=2.15, P=0.036). The horizontal canal gain of htSN is positively correlated with the anterior canal gain (r=0.74, P<0.001).(4)The affected semicircular canals in the two groups with no-vertical-component nystagmus (nSN and hSN) and the htSN were counted. The composition ratio of the affected semicircular canals in the two groups was different (χ2=8.34, P=0.015). Conclusion: The occurrence of SN in patients with VN is related to many factors, such as the disease course, low and high frequencies, and the severity of the condition in the affected semicircular canal.

1. The H9N2 subtype avian influenza virus can infect both chickens and humans. Previous studies have reported a role for erythrocytes in immunity. However, the role of H9N2 against chicken erythrocytes and the presence of complement-related genes in erythrocytes has not been studied. This research investigated the effect of H9N2 on complement-associated gene expression in chicken erythrocytes.2. The expression of complement-associated genes (C1s, C1q, C2, C3, C3ar1, C4, C4a, C5, C5ar1, C7, CD93 and CFD) was detected by reverse transcription-polymerase chain reaction (RT-PCR). Quantitative Real-Time PCR (qRT-PCR) was used to analyse the differential expression of complement-associated genes in chicken erythrocytes at 0 h, 2 h, 6 h and 10 h after the interaction between H9N2 virus and chicken erythrocytes in vitro and 3, 7 and 14 d after H9N2 virus nasal infection of chicks.3. Expression levels of C1q, C4, C1s, C2, C3, C5, C7 and CD93 were significantly up-regulated at 2 h and significantly down-regulated at 10 h. Gene expression levels of C1q, C3ar1, C4a, CFD and C5ar1 were seen to be different at each time point. The expression levels of C1q, C4, C1s, C2, C3, C5, C7, CFD, C3ar1, C4a and C5ar1 were significantly up-regulated at 7 d and the gene expression of levels of C3, CD93 and C5ar1 were seen to be different at each time point.4. The results confirmed that all the complement-associated genes were expressed in chicken erythrocytes and showed the H9N2 virus interaction with chicken erythrocytes and subsequent regulation of chicken erythrocyte complement-associated genes expression. This study reported, for the first time, the relationship between H9N2 and complement system of chicken erythrocytes, which will provide a foundation for further research into the prevention and control of H9N2 infection.

Orofaciodigital syndrome type 1 (OFDS1) is a genetic disorder characterized by specific oral, facial, and limb malformations. A 14-month-old girl with congenital cleft palate, lower lip midline cleft, and digital anomalies admitted to our hospital was preliminarily diagnosed with OFDS1. Genetic analysis revealed that she carried a heterozygous variant of OFD1 at locus Xp22.2 on the X chromosome. Herein, we present the specific phenotype and genotype and the treatment modalities for this patient and references for diagnosing and treating OFDS.

Since almost all patients with an alveolar cleft have a deviated and thickened vomer bone, the purpose of this study was to investigate the relationship between the vomer shape and the size of the alveolar cleft in patients with unilateral cleft lip and alveolus (CLA). A total of 40 adult patients with unilateral CLA were enrolled, and 40 normal adults without CLA were enrolled as controls. All patients underwent preoperative computed tomography scans and analysis by computer-aided engineering software to obtain the vomer volume (VV), deviated septal angle (DSA), and alveolar cleft volume (ACV). An independent-sample t test or nonparametric test was used to compare the VV and DSA between the unilateral CLA and control groups. The correlation between ACV, VV, and DSA in the unilateral CLA group was assessed using Pearson correlation analysis or Spearman correlation analysis. Vomer volume was significantly higher in patients with CLA (1595.35±48.45 mm3) than in the control group (1043.2±164.976 mm3) (P<0.001), as was DSA (13.099±7.0 versus 3.4398±1.74 degrees) (P<0.001). In the CLA group, VV and DSA were significantly associated with ACV (VV and ACV: r=0.886, P<0.001; DSA and ACV: r=0.543, P<0.001), and VV was significantly correlated with DSA (VV and DSA: r=0.582, P<0.001). In conclusion, the vomer is thicker and more convex in patients with unilateral CLA than in people without, and the vomer angle and degree of volume deviation correlate with alveolar cleft severity.

BACKGROUND: No standard of care for mucosal melanoma (MM) in the adjuvant setting has been established. Meanwhile, relapse-free survival (RFS) is only â¼5 months after surgery alone. This phase II trial aimed to compare toripalimab versus high-dose interferon-α2b (HDI) as an adjuvant therapy for resected MM. PATIENTS AND METHODS: From July 2017 to May 2019, 145 patients with resected MM were randomized (1 : 1) to receive HDI (n = 72) or toripalimab (n = 73) for 1 year until disease relapse/distant metastasis, unacceptable toxicity, or withdrawal of consent. The primary endpoint was RFS. The secondary endpoints included distant metastasis-free survival (DMFS), overall survival (OS), and safety. RESULTS: After a median follow-up of 26.3 months, the number of RFS, OS, and DMFS events was 51 versus 46, 33 versus 29, and 49 versus 44 in the toripalimab arm and the HDI arm, respectively. The median RFS was 13.6 [95% confidence interval (CI) 8.31-19.02] months and 13.9 (95% CI 8.28-19.61) months in the toripalimab arm and the HDI arm, respectively. The DMFS was not significantly different between the two arms [hazard ratio (HR) 1.00; 95% CI 0.65-1.54]. The median OS was 35.1 months (95% CI 27.93 months-not reached) in the toripalimab arm, with no significant difference in all-cause death (HR 1.11, 95% CI 0.66-1.84) for the two arms. The median sums of the patients' actual infusion doses were 3672 mg and 1054.5 MIU in the toripalimab arm and the HDI arm, respectively. The incidence of treatment-emergent adverse events with a grade ≥3 was much higher in the HDI arm than in the toripalimab arm (87.5% versus 27.4%). CONCLUSIONS: Toripalimab showed a similar RFS and a more favorable safety profile than HDI, both better than historical data, suggesting that toripalimab might be the better treatment option. However, additional translational studies and better treatment regimens are still warranted to improve the clinical outcome of MM.

Objective: To analyze the efficacy and safety of toripalimab combined with axitinib in the treatment of advanced renal cell carcinoma. Methods: Clinical data of 50 patients with advanced renal cell carcinoma who received axitinib combined with toripalimab were retrospectively collected from the database of Peking University Cancer Hospital. ORR, DCR, PFS, and OS were analyzed. Results: Among the 50 patients, 37 were males; median age was 56 (22-73) years; 38 were pathologically diagnosed as clear cell renal cell carcinoma and 12 were non-clear cell carcinoma. Common metastatic sites included lung, bone, lymph node, liver, and so on. 90% of the patients had received at least one-line of systemic therapy. With a median follow-up time of 11.9 months (0.8-24), 27 of the 50 patients are still on treatment, ORR was 34%, DCR was 86%, median PFS was 13.1 months (95%CI 5.8-20.4), and median OS has not yet reached. One-year OS rate was 84.6%. Common adverse reactions were proteinuria, diarrhea, hypertension, abnormal thyroid function, elevated transaminase, and hand-foot syndrome. Most adverse events were grade 1-2. Conclusion: Toripalimab combined with axitinib was efficient in the treatment of advanced renal cell carcinoma, and had manageable adverse reactions.

OBJECTIVE: To evaluate urinary continence recovery time and risk factors of urinary continence recovery after robot-assisted laparoscopic radical prostatectomy (RARP). METHODS: From January 2019 to January 2021, a consecutive series of patients with localized prostate cancer (cT1-T3, cN0, cM0) were prospectively collected. RARP with total anatomical reconstruction was performed in all the cases by an experienced surgeon. Lymph node dissection was performed if the patient was in high-risk group according to the D'Amico risk classification. The primary endpoint was urinary continence recovery time after catheter removal. Postoperative and pathological variables were analyzed. Continence was rigo-rously analyzed 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks after catheter removal. Continence was evaluated by recording diaper pads used per day, and all the patients were instructed to perform the 24-hour pad weight test until full recovery of urinary continence. The patient was defined as continent if no more than one safety pad were needed per day, or no more than 20-gram urine leakage on the 24-hour pad weight test. Time from catheter removal to full recovery of urinary continence was recorded, and risk factors influencing continence recovery time evaluated. RESULTS: In total, 166 patients were analyzed. The mean age of the enrolled patients was 66.2 years, and the median prostate specific antigen (PSA) was 8.51 µg/L. A total of 59 patients (35.5%) had bilateral lymphatic dissection, and 28 (16.9%) underwent neurovascular bundle (NVB) preservation surgery. Postoperative pathology results showed that stage pT1 in 1 case (0.6%), stage pT2 in 77 cases (46.4%), stage pT3 in 86 cases (51.8%), and positive margins in 28 patients (16.9%). Among patients who underwent lymph node dissection, lymph node metastasis was found in 7 cases (11.9%). Median continence recovery time was one week. The number of the continent patients at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 65 (39.2%), 32 (19.3%), 34 (20.5%), 24 (14.5%), and 9 (5.4%). Two patients remained incontinent 24 weeks after catheter removal. The continence rates after catheter removal at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 39.2%, 58.4%, 78.9%, 93.4%, and 98.8%, respectively. Univariate COX analysis revealed that diabetes appeared to influence continence recovery time (OR=1.589, 95%CI: 1.025-2.462, P=0.038). At the end of 48 hours, 4 weeks, 12 weeks, and 24 weeks after catheter removal, the mean OABSS score of the continent group was significantly lower than that of the incontinent group. CONCLUSION: RARP showed promising results in the recovery of urinary continence. Diabetes was a risk factor influencing continence recovery time. Bladder overactive symptoms play an important role in the recovery of continence after RARP.

The Australian Health Economics Model of Osteoporosis (AusHEMO) has shown good face, internal and cross validities, and can be used to assist healthcare decision-making in Australia. PURPOSE: This study aimed to document and validate the risk engine of the Australian Health Economics Model of Osteoporosis (AusHEMO). METHODS: AusHEMO is a state-transition microsimulation model. The fracture risks were simulated using fracture incidence rates from the Dubbo Osteoporosis Epidemiology Study. The AusHEMO was validated regarding its face, internal and cross validities. Goodness-of-fit analysis was conducted and Lin's coefficient of agreement and mean absolute difference with 95% limits of agreement were reported. RESULTS: The development of AusHEMO followed general and osteoporosis-specific health economics guidelines. AusHEMO showed good face validity regarding the model's structure, evidence, problem formulation and results. In addition, the model has been proven good internal and cross validities in goodness-of-fit test. Lin's coefficient was 0.99, 1 and 0.94 for validation against the fracture incidence rates, Australian life expectancies and residual lifetime fracture risks, respectively. CONCLUSIONS: In summary, the development of the risk engine of AusHEMO followed the best practice for osteoporosis disease modelling and the model has been shown to have good face, internal and cross validities. The AusHEMO can be confidently used to predict long-term fracture-related outcomes and health economic evaluations when costs data are included. Health policy-makers in Australia can use the AusHEMO to select which osteoporosis interventions such as medications and public health interventions represent good value for money.

ABSTRACT: Precise volumetric evaluation of the alveolar cleft facilitates accurate preparation of bone substitutes and reduces donor site morbidity. This study investigates 2 advanced presurgical volumetric assessment methods that use computer-aided engineering (CAE) software. Preoperative computed tomography (CT) scans from 20 unilateral alveolar cleft patients undergoing secondary alveolar bone grafting (SABG) were analyzed by CAE software. Cleft defect volumes were calculated using the mirror-reversed technique and the subtraction method. The mirror-reversed technique determines defect volume by reversing the noncleft side to the cleft side. The subtraction method determines defect volume by subtracting a mask of the preoperative cleft from a mask generated after simulated cleft filling. The mean defect volumes and calculation times of the mirror-reversed technique (1.27â±â0.35âcm3; 11.80â±â1.79âseconds) and the subtractive method (1.23â±â0.32âcm3; 9.43â±â1.35âseconds) did not differ significantly. In Bland-Altman analysis the 2 methods were equivalent for alveolar cleft defect assessment. Both methods exhibited acceptable interobserver reliability, high precision, clinical convenience, time efficiency, and high reproducibility, and can serve as valuable tools for the planning and execution of SABG. The subtraction method has broader potential applicability and can simulate intraoperative bone grafting more effectively.

BACKGROUND: Blepharoplasty has become one of the most popular plastic surgery techniques for generating double-eyelid folds. The mini-incision blepharoplasty technique results in minimal trauma and the formation of supratarsal folds. METHODS: In this study, the authors combined mini-incisions with interrupted buried sutures. To perform the blepharoplasty procedure, the authors marked the supratarsal folds and divided them into 5 line segments: 3 cutting lines and 2 noncutting lines. For the cutting lines, the authors used orbicularis-tarsus fixation to form double eyelids and only removed a small strip of muscle under the incision to maintain the physiological structure of the pretarsal tissue. For the noncutting lines, the authors used the interrupted buried suture technique to add 2 fixed points. RESULTS: A total of 42 patients (mean age 25.25 years) underwent this minimally invasive blepharoplasty. Among these patients, 42 underwent bilateral surgery. The average follow-up period was 35.91 months (range: 13-47 months). Only one patient underwent a second operation to address a shallow, unilateral supratarsal crease. Nonetheless, all patients were satisfied with their results. CONCLUSION: Our minimally invasive blepharoplasty approach resulted in minimal damage to the pretarsal tissues and robust supratarsal folds and is relatively easy to perform for the novice surgeon. EVIDENCE STATEMENT: Level IV.

An earlier systematic review on interventions to improve adherence and persistence was updated. Fifteen studies investigating the effectiveness of patient education, drug regimen, monitoring and supervision, and interdisciplinary collaboration as a single or multi-component intervention were appraised. Multicomponent interventions with active patient involvement were more effective. INTRODUCTION: This study was conducted to update a systematic literature review on interventions to improve adherence to anti-osteoporosis medications. METHODS: A systematic literature review was carried out in Medline (using PubMed), Embase (using Ovid), Cochrane Library, Current Controlled Trials, ClinicalTrials.gov , NHS Centre for Review and Dissemination, CINHAL, and PsycINFO to search for original studies that assessed interventions to improve adherence (comprising initiation, implementation, and discontinuation) and persistence to anti-osteoporosis medications among patients with osteoporosis, published between July 2012 and December 2018. Quality of included studies was assessed. RESULTS: Of 585 studies initially identified, 15 studies fulfilled the inclusion criteria of which 12 were randomized controlled trials. Interventions were classified as (1) patient education (n = 9), (2) drug regimen (n = 3), (3) monitoring and supervision (n = 2), and (4) interdisciplinary collaboration (n = 1). In most subtypes of interventions, mixed results on adherence (and persistence) were found. Multicomponent interventions based on patient education and counseling were the most effective interventions when aiming to increase adherence and/or persistence to osteoporosis medications. CONCLUSION: This updated review suggests that patient education, monitoring and supervision, change in drug regimen, and interdisciplinary collaboration have mixed results on medication adherence and persistence, with more positive effects for multicomponent interventions with active patient involvement. Compared with the previous review, a shift towards more patient involvement, counseling and shared decision-making, was seen, suggesting that individualized solutions, based on collaboration between the patient and the healthcare provider, are needed to improve adherence and persistence to osteoporosis medications.

A series of bis(4-alkoxyphenyl) viologen bis(triflimide) salts with alkoxy chains of different lengths were synthesized by the metathesis reaction of respective bis(4-alkoxyphenyl) viologen dichloride salts, which were in turn prepared from the reaction of Zincke salt with the corresponding 4-n-alkoxyanilines, with lithium triflimide in methanol. Their chemical structures were characterized by 1H and 13C nuclear magnetic resonance spectra and elemental analysis. Their thermotropic liquid-crystalline (LC) properties were examined by differential scanning calorimetry, polarizing optical microscopy, and variable temperature X-ray diffraction. Salts with short length alkoxy chains had crystal-to-liquid transitions. Salts of intermediate length alkoxy chains showed both crystal-to-smectic A (SmA) transitions, Tms, and SmA-to-isotropic transitions, Tis. Those with longer length of alkoxy chains had relatively low Tms at which they formed the SmA phases that persisted up to the decomposition at high temperatures. As expected, all of them had excellent thermal stabilities in the temperature range of 330-370 °C. Their light-emitting properties in methanol were also included.

The multidisciplinary co-management program for geriatric patients with hip fracture is cost-effective in the Chinese population and it has the potential to be scaled up in China. INTRODUCTION: The study aimed to investigate the cost-effectiveness of a multidisciplinary co-management program for patients with hip fracture in China. METHODS: Hip fracture patients who were admitted to an orthopedic hospital in Beijing were included in the multidisciplinary co-management program. The cost-effectiveness of intervention was evaluated compared to the conventional management. A Markov microsimulation model was developed to simulate lifetime costs and effectiveness. Costs including intervention, hospitalization, medications, and long-term care costs were expressed using 2019 US dollars and the healthcare perspective was adopted. Effectiveness was evaluated using both 1-year mortality-averted and quality-adjusted life years (QALYs). Costs and effectiveness were discounted at 5% per annum. The willingness-to-pay (WTP) threshold was set at $26,481 per QALY gained which was three times gross domestic product (GDP) per capita in China. One-way and probabilistic sensitivity analyses were conducted. RESULTS: The lifetime cost for the conventional management (n = 1839) and intervention group (n = 1192) was $11,975 and $13,309 respectively. The lifetime QALYs were 2.38 and 2.45 years and the first-year mortality was 17.8% and 16.1%. The incremental cost-effectiveness ratio was $19,437 per QALY gained or $78,412 per 1-year mortality-averted. Given the Chinese WTP threshold, the intervention had a 78% chance being cost-effective. The cost-effectiveness of the intervention was sensitive to cost of intervention and the proportion of patients who underwent surgery within 48 h. CONCLUSIONS: The multidisciplinary co-management program for patients with hip fracture is cost-effective and it has the potential to be scaled up in the Chinese population.
