ABSTRACT

Objectives: This cross-sectional study compared the healthcare expenditures associated with multimorbidity (having ≥2 chronic conditions) versus no multimorbidity among older United States (US) adults (aged ≥ 50 years) with self-reported pain in the past 4 weeks. Methods: This research used data from the 2018 Medical Expenditure Panel Survey. Adjusted linear regression models evaluated group differences in various annual healthcare expenditures. Results: Descriptive statistics indicated multimorbidity was associated with all personal characteristics (p < 0.05) except gender and smoking status (p > 0.05). Multimorbidity had 75.8% greater annual total health expenditures (p = 0.0083), 40.6% greater office-based expenditures (p = 0.0224), 100.6% greater prescription medication costs, (p = 0.0268), yet 47.3% lower inpatient expenditures (p = 0.0158), and 56.6% lower home healthcare expenditures (p < 0.0001) than no multimorbidity. Discussion: This study found greater healthcare expenditures among older US adults with pain and multimorbidity, which captures the financial burden of comorbidity in this population.

ABSTRACT

BACKGROUND: Smartphones have become an essential part of everyday life and it is undeniable that apps offer enormous opportunities for dealing with future challenges in public health. Nevertheless, the exact patient requirements for medical apps in the field of orthopedic and trauma surgery are currently unknown.

OBJECTIVE: The aim of this study was to define target groups, evaluate patient requirements, and the potential and pitfalls regarding medical apps specific for patients receiving orthopedic and trauma surgical care.

METHODS: A prospective multicenter study was conducted between August 2018 and December 2019 at a German trauma center and 3 trauma surgery/orthopedic practices. A paper-based survey consisting of 15 questions evaluated information regarding smartphone and medical app usage behavior. In addition, suggested app functions were rated using Likert scales. Descriptive statistics and binary log-binomial regression were performed.

RESULTS: A total of 1055 questionnaires were included in our statistical analysis. Approximately 89.57% (945/1055) of the patients in this study owned a smartphone. Smartphone ownership probability decreased with every decade of life and increased with higher levels of education. Medical information was obtained via mobile web access by 62.65% (661/1055) of the patients; this correlated with smartphone ownership in regard to age and educational level. Only 11.18% (118/1055) of the patients reported previous medical app usage, and 3.50% (37/1055) of the patients received an app recommendation from a physician. More than half (594/1055, 56.30%) of the patients were unwilling to pay for a medical app. The highest rated app functions were information about medication, behavioral guidelines, and medical record archival. An improved treatment experience was reported through the suggested app features by 71.18% (751/1055) of the patients.

CONCLUSIONS: Mobile devices are a widely used source of information for medical content, but only a minority of the population reported previous medical app usage. The main target group for medical apps among patients receiving orthopedic and trauma surgical care tends to be the younger population, which results in a danger of excluding fringe groups, especially the older adults. Education seems to be one of the most important pull factors to use smartphones or a mobile web connection to obtain health information. Medical apps primarily focusing on an optimized patient education and flow of information seem to have the potential to support patients in health issues, at least in their subjective perception. For future target group-oriented app developments, further evidence on the clinical application, feasibility, and acceptance of app usage are necessary in order to avoid patient endangerment and to limit socioeconomic costs.

ABSTRACT

Objective: To investigate the general situation, detection range, testing reagents, and clinical performance of non-invasive prenatal testing (NIPT) for fetal chromosomal copy number variations (CNVs) in Chinese laboratories. Methods: The National Center for Clinical Laboratories of the National Health Commission designed a questionnaire for the detection of CNVs by NIPT, which included the investigation of whether the laboratory has carried out NIPT to detect CNVs and its testing scope, reagents/platforms, intended uses, screening populations and clinical performance. The questionnaires were distributed to 355 laboratories in 31 provinces, autonomous regions, and municipalities across the country on October, 2020. Further, the feedbacks were statistical analyzed. Results: Two hundred and twenty-eight laboratories had performed NIPT to detect CNVs, including 116 types of CNVs, and more than 95% of laboratories chose to detect the CNVs of 5p15 deletion, 22q11.2 deletion, 1p36 deletion, and 15q11.2 deletion. All testing reagents used were laboratory-developed tests and were based on massive parallel sequencing, the minimum amount of sequencing data was 3-15 M reads, the detection limit of fetal fraction was 3%-5%, and the minimum size of variants that can be detected was 1-5 Mb. The proportion of laboratories that apply CNVs testing for daily project, voluntary requirements of patients, and scientific research were 58.8% (134/228), 57.5% (131/228), and 20.6% (47/228), respectively. One hundred and thirty-four laboratories were fully or partially aware of the clinical performance of NIPT to detect microdeletion/microduplication syndromes, and the laboratories’ declared sensitivity of NIPT for Cri du Chat syndrome, 22q11.2 deletion syndrome, 1p36 deletion syndrome, and Angelman syndrome were 50.0%-100%, 60.0%-100%, 50.0%-100%, and 33.3%-100%, and the positive predictive values were 9.0%-50.0%, 18.0%-100%, 20.0%-30.0%, and 20.0%. Conclusion: The detection of CNVs by NIPT in Chinese laboratories need to be standardized. Laboratories should detect CNVs with clear clinical significance in accordance with the guidelines, conduct performance validation of the reagents, then perform NIPT test and provide adequate interpretation after mastering the clinical performance sufficiently.

ABSTRACT

Objective: To investigate the application status of optimal medical therapy (OMT) in patients with coronary heart disease after percutaneous coronary intervention (PCI) and its influence on the 1-year prognosis of patients after surgery. Methods: Data of 3 812 patients diagnosed with coronary heart disease by coronary angiography and successfully completed PCI in the Department of Cardiology, TEDA International Cardiovascular Hospital from October 2016 to September 2017 were prospectively collected. The OMT status and the occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) during the hospitalization and 1, 6, and 12 months after discharge were recorded. Patients were divided into OMT group (n=1 299) and non-OMT group (n=2 289) according to their adherence to OMT after PCI. Chi-square test was used to compare the differences of MACCE between groups, and to screen for significant differences and clinically significant variables between groups. Cox regression model was used to analyze the influencing factors of MACCE after PCI. Results: Among 3 588 patients (224 cases lost to follow-up), 58.8% (2 110/3 588) used OMT during hospitalization after PCI, and 36.0% (1 293/3 588) still adhered to OMT after 12 months of follow-up. The utilization rates of OMT showed a decreasing trend, among which till the 12^th month, β-blockers and ACEI/ARB showed the greatest decreasing degree, from 75.3%(2 701/3 588) and 75.1%(2 692/3 588) to 59.1%(2 122/3 588) and 53.0%(1 903/3 588). Pearson χ² analysis showed that elderly patients, the number of amalgamative diseases, history of PCI, history of chronic myocardial infarction, history of chronic renal insufficiency, the lesion counts, lesion type, the Gensini score, adhere to the OMT and smoking during the follow-up were related to postoperative MACCE, the difference was statistically significant (P<0.05). Cox regression model showed that OMT adherence after PCI was an independent protective factor for postoperative MACCE events (HR=0.471,95%CI: 0.300-0.734, P=0.001). Conclusion: The application of OMT after PCI was suboptimal, and the application rate decreased with the lengthening of the discharge time, among which the use of ACEI/ARB and β-blockers deserved more attention. Adherence to OMT after PCI was an independent protective factor, which could reduce the incidence of postoperative MACCE and improve the prognosis of patients.

ABSTRACT

Objective: To investigate the clinical efficacy and safety analysis of bronchial thermoplasty (BT) in the treatment of severe asthma and asthma-chronic obstructive pulmonary disease overlap. Methods: The clinical data of 49 patients with asthma-COPD overlap who received BT in the University of Chinese Academy of Sciences Shenzhen Hospital from January 2016 to December 2018 and 50 patients with severe asthma who received BT in the same period were retrospectively analyzed. Patients were divided into overlap group and asthma group, and the baseline data of two groups were recorded. The pulmonary function before and after treatment (including forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁), FEV₁ as a percentage of predicted value (FEV₁% pred)), hormone consumption, asthma control test (ACT) score, asthma quality of life questionnaire (AQLQ) score, asthma control questionnaire (ACQ) score, the overlap group before and after treatment COPD assessment test (CAT) score, modified British Medical Research Council (mMRC) score and postoperative respiratory adverse events in the next 3 weeks were comparatively analyzed. Results: The general baseline characteristics of the two groups are compared. The patients in the overlap group were older than those in the asthma group, and the course of disease and smoking history were longer than those in the asthma group. The inhaled hormone dosage in asthma group was greater than those in the overlap group ((64±11) years vs (48±11) years; 10.00 (10.00, 25.00) years vs 9.00 (1.75, 20.00) years; 20.00(2.00, 40.00) years vs 0 (0, 10.00) years; 320 (320, 640) μg/d vs 960 (320, 960) μg/d) (all P<0.05). The predicted values of lung function indexes FVC, FEV₁, FEV₁% pred in the overlap group before treatment were all lower than those in the asthma group (1.98 (1.43, 2.43) L vs 2.54 (2.02, 3.15) L; 0.92 (0.61, 1.26) L vs 1.69(1.17, 2.16) L; (50±16) L vs (65±14) L) (all P<0.05). There were no significant differences in ACT, ACQ, and AQLQ scores between the two groups before treatment (all P>0.05). Within 3 months after treatment, except for no significant improvement in FEV₁% predicted value and inhaled hormone dosage in the overlap group (all P>0.05), other indexes in both groups were improved compared with those before treatment (all P<0.05). After 1 year of treatment, all indexes of the two groups were significantly improved than those before treatment, and all indexes of the asthma group were better than those of the overlap group (all P<0.05). In terms of respiratory adverse events occurring within 3 weeks after the operation, the incidence of cough and bloody sputum in the overlap group was higher than that in the asthma group, while the incidence of sputum and short-term wheezing was lower than that in the asthma group (all P<0.05). There were no statistically significant differences in the incidence of chest tightness, chest pain, segmental atelectasis and pneumonia between the two groups (all P>0.05), and the postoperative adverse reactions could be effectively controlled in a short period of time. Conclusion: BT treatment could not only improve the lung function, clinical symptoms and quality of life of asthmatic patients, but was also effective for asthma-COPD overlap patients. However, BT treatment had more benefits for asthmatic patients without serious adverse events occurred.

ABSTRACT

Objective: To compare the clinical efficacy and the level of muscle and soft tissue damage between modified posteromedial approach via lateral side of flexor hallucis longus and modified posteromedial approach in the treatment of posterior Pilon fracture. Methods: Total of 43 patients (27 males and 16 females, aged from 19 to 71 years) diagnosed with posterior Pilon fracture from June 2016 to June 2018 in Foshan Hospital of Traditional Chinese Medicine were randomly divided into observation group (modified posteromedial approach via lateral side of flexor hallucis longus, 21 cases) and control group (modified posteromedial approach, 22 cases) according to the operation approach. The preoperative waiting time, intraoperative time, intraoperative blood loss, hospitalization time and the complications were recorded and compared between the two groups. The differences of blood creatine kinase (CK), myoglobin (Myo) and C-reactive protein (CRP) at different time points before and after operation were compared between the two groups to elevate the level of muscle and soft tissue damage. The fracture reduction qualities of the two groups were compared by Burwell-Charnley criteria. The differences of fracture healing time, range of motion of metatarsophalangeal joint of the great toe (MTP-ROM), ankle range of motion (Ankle-ROM), American Orthopaedic Foot & Ankle Society (AOFAS) score and visual analogue scale (VAS) score of pain were compared between the two groups at the last follow-up. Results: The observation group and the control group were followed-up for (19±6) months and (16±8) months, respectively; there was no significant difference between the two groups (P>0.05). There were no significant differences in preoperative waiting time, intraoperative blood loss, hospitalization time and fracture healing time between the two groups (all P>0.05). At the last follow-up, there was no significant difference in the MTP-ROM and Ankle-ROM between the two groups (both P>0.05); the AOFAS score of the observation group was 88.2±7.8 and it was 84.5±7.6 in the control group (P>0.05); the VAS score of the observation group was (0.9±1.0) and it was (1.3±0.8) in the control group(P>0.05). Anatomical reduction rate in observation group was higher than that in control group (90.5% vs 81.8%, P>0.05). The operation time in the observation group was (87±16) min and it was (98±11) min in the control group (P<0.05). CK, Myo and CRP were increased in both groups after surgery, but there was no statistical significance between groups at the same time point (all P>0.05). There was no nerve injury in the observation group, while 2 cases (9.0%) of nerve paralysis occurred in the control group. No incision infection and checkrein deformity of the Hallux was found in the two groups. Conclusion: The modified posteromedial approach via lateral side of flexor hallucis longus can obtain good operative field exposure, and does not increase muscle and soft tissue injury, with shorter operative time and fewer complications, without nerve injury and checkrein deformity, it is a safe approach for the treatment of posterior Pilon fracture.

ABSTRACT

INTRODUCTION: Recurrent venous thromboembolism (VTE) despite curative anticoagulation is frequent in patients with cancer. Identifying patients with a high risk of recurrence could have therapeutic implications. A prospective study was designed to validate the Ottawa risk score of recurrent VTE in cancer patients.

METHODS: In a prospective multicenter observational cohort, adult cancer patients with a recent diagnosis of symptomatic or incidental lower limb deep vein thrombosis or pulmonary embolism were treated with tinzaparin for 6 months. The primary endpoint was the recurrence of symptomatic or asymptomatic VTE within the first 6 months of treatment. All clinical events were centrally reviewed and adjudicated. Time-to-event outcomes were estimated by the Kalbfleisch and Prentice method to take into account the competing risk of death. A C-statistic value >0.70 was needed to validate the Ottawa score.

RESULTS: A total of 409 patients were included and analyzed on an intention-to-treat basis. Median age was 68 years, 60.4% of patients had PE, VTE was symptomatic in 271 patients (66.3%). The main primary sites were lung (31.3%), digestive tract (18.3%) and breast (13.9%) cancers. The Ottawa score was high (≥1) in 58% of patients. The 6-month cumulative incidence of recurrent VTE was 7.3% (95% confidence interval [CI]: 4.9-11.1) overall, and 5.0% (95%CI: 2.3-10.8) vs 9.1% (95%CI: 6.1-13.6) in the Ottawa low vs high risk groups, respectively. The C-statistic value was 0.60 (95%CI: 0.55-0.65).

CONCLUSION: In this prospective cohort of patients with cancer receiving tinzaparin for VTE, the Ottawa score failed to accurately predict recurrent VTE.

ABSTRACT

Objective: To investigate the prognosis and postoperative complications of local excision for rectal cancer after neoadjuvant chemoradiotherapy (nCRT). Methods: A descriptive case series study was carried out. Patient inclusion criteria: (1) patients who underwent local excision by transanal endoscopic microsurgery (TEM) after nCRT; (2) magnetic resonance evaluated tumor regression grade (mrTRG) as 1, 2 after nCRT;(3) American Society of Anesthesiologists class I to III. Patient exclusion criteria: (1) with multiple primary colorectal cancers; (2) with other malignant tumors within five years; (3) with emergency surgicery indications like digestive tract obstruction, perforation or bleeding. Clinicopathological and follow-up data of rectal cancer patients with obvious tumor regression after nCRT who underwent local excision in Peking Union Medical College Hospital from January 2010 to August 2019 were retrospectively collected. Outcome measures included disease-free survival (DFS), short-term postoperative complications, and at postoperative 1-year during follow up, gas continence, fecal continence, and quality of life (using the EORTC QLQ-CR29 scale, higher score indicated worse quality of life) at postoperative 1-year. Results: A total of 40 patients were included in this study. There were 27 males and 13 females with an average age of (66.7±12.3) years. Preoperative rectal ultrasound and other imaging examinations indicated that the tumor was located in the anterior wall in 16 cases, the lateral wall in 12 cases, and the posterior wall in 12 cases. The distance between the lower margin of the tumor and the anal verge was (4.3±1.2) cm before nCRT and (5.1±0.9) cm after nCRT. According to mrTRG, 31 cases were assessed as mrTRG 1 and 9 cases as mrTRG 2. All the patients received local extended excision of rectal cancer using TEM platform. A total of 19 cases(47.5%) suffered from complications within one month postoperatively. Clavien-Dindo grade I complications happened in 14 cases, grade II in 3 patients, and grade III in 2 cases, who all were healed by conservative treatment. Except that 2 patient presented severe low anterior resection syndrome (LARS) at 1 year postoperatively, no severe anal dysfunction was found in this cohort patients. EORTC QLQ CR29 scale results for quality of life showed that at 1 year after TEM excision, except taste (Z=-1.968, P=0.049), anxiety (Z=-3.624, P<0.001) and skin irritation (Z=-2.420, P=0.023) were worse than the situation before neoadjuvant therapy, there were no statistically significant differences in other assessment results between pre-operation and post-operation (all P>0.05). Postoperative pathological results indicated complete tumor regression (pTRG0) in 17 cases, moderate remission (pTRG1) in 13, and mild remission (pTRG2) in 10. During the follow-up of (49.1±29.6) months, 3 patients had local recurrence and 4 had distant metastasis (3 patients with liver metastasis and 1 patient with lung metastasis followed by liver metastasis). No death was found and the 5-year disease-free survival (DFS) was 84.3%. Conclusions: Local excision through TEM following nCRT not only can be adopted as an important means to accurately determine complete clinical remission (cCR), but also has high therapeutic value for rectal cancer patients presenting cCR or near cCR, with little impact on defecatory function and quality of life. However, the morbidity of complication of TEM excision after nCRT is relatively high and there is a risk of recurrence and metastasis. Therefore, it is still necessary to strictly select the indications of local excision.

ABSTRACT

Objective: To analyze the diagnostic performance of serum and bronchoalveolar lavage fluid (BALF) galactomannan (GM) test in invasive pulmonary aspergillosis(IPA) with severe and critically ill influenza. Methods: A retrospective study was performed for 157 patients with severe and critically ill influenza admitted to the Department of Pulmonary and Critical Care Medicine of the First Affiliated Hospital of Wenzhou Medical University from December 2017 to April 2019.Clinical characteristics and serum and BALF GM values were collected. The patients were divided into an IPA group (n=18) and a non-IPA group (n=139). The definition of IPA modified from AspICU algorithm taken as the gold standard (The corresponding clinical manifestations, imaging manifestations and microbiological diagnostic criteria should be met simultaneously), the performance of serum and BALF GM test and their combination to IPA with influenza were analyzed respectively and receiver operating characteristic curve (ROC) was drawn. Results: A total of 157 cases were enrolled, 95 were critically ill, and the mortality of IPA with influenza was 55.6%(10/18). The APACHE Ⅱ score, PSI score, urea nitrogen, influenza severity (Percentage of critically ill influenza) and invasive ventilator in IPA group were (16±6), (110±31), 10.7 (8.4, 17.8) mmol/L, 88.9% and 66.7%, respectively, which were significantly higher than those in non-IPA group [(10±5), (83±30), 5.2 (3.6, 7.6) mmol/L, 56.8% and 24.5%, P<0.05]. All patients received serum GM test and 32 patients performed BALF GM test at the same time. When the cut-off valve of serum GM test was 0.5 μg/L, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 66.7% (12/18), 95.0% (132/139), 63.2% (12/19) and 95.7% (132/138) respectively. When the cut-off value of BALF GM test was 1.0 μg/L, the sensitivity, specificity, PPV and NPV were 80%(8/10),86.4%(19/22),72.7%(8/11)and 90.5%(19/21)respectively. The BALF GM cut-off value of 0.88 μg/L showed the highest diagnostic efficacy for IPA, for which the sensitivity and specificity were 90%(9/10) and 86.4%(19/22). The areas under the ROC curve of serum GM, BALF GM, and the combination of them were 0.81, 0.85, and 0.94 respectively. The difference was statistically significant (P<0.05) and the combined diagnosis efficiency was higher. Conclusions: Critically ill influenza patients should be alert for IPA. The sensitivity of serum GM test in the diagnosis of IPA with influenza was low, while the NPV was high. The optimum BALF GM cut-off value was 0.88 μg/L. The combination with BALF and serum GM test can improve the diagnostic performance.

ABSTRACT

BACKGROUND AND OBJECTIVES: The 6-minute walk test (6MWT), as a clinical assessment tool for functional exercise capacity, is an integral component of lung allocation scores (LASs). In times of the coronavirus disease (COVID-19) pandemic, patients underwent 6MWTs wearing a surgical mask in ambulatory care. We investigated the impact of wearing a mask on 6-minute walk distances (6MWDs).

METHOD: 6MWDs of 64 patients with end-stage lung diseases wearing an oronasal surgical mask were retrospectively compared to previously investigated 6MWDs of the same cohort, in a pre-COVID-19 pandemic era, without wearing a mask. Four patients were excluded due to a primary vascular disease, 29 patients due to clinically unstable pulmonary functions, and 1 patient due to a psychiatric disorder.

RESULTS: The median age of the patients included was 55 (46-58) years; 15 (48%) were male. Ten (32.2%) were on the Eurotransplant lung transplant waiting list with a median LAS of 34.3 (31.9-36.2). Twenty (64.5%) patients had chronic obstructive pulmonary diseases, 7 (22.6%) had interstitial lung diseases, and 4 (12.9%) had other end-stage lung diseases. The mean 6MWD without versus with wearing a mask was 306.9 (101.9) versus 305.7 (103.8) m, with a mean difference of -1.19 m (95% confidence interval -13.4 to 11.03). The observed difference is statistically equivalent to zero (p < 0.001). No significant differences in 6MWDs were observed between the clinical groups.

CONCLUSION: Wearing an oronasal surgical mask did not affect the 6MWDs of patients with advanced lung diseases. Therefore, a masked 6MWT appears to provide a reliable examination of functional exercise capacity in this cohort.
