Abstract
The aim of this study was to evaluate the effect on the results of patients applied with arthroscopic full layer total layer rotator cuff repair made according to the shape and size of the tear.
The study included a total of 120 patients applied with arthroscopic full layer rotator cuff repair as single or double row repair. The patients were separated into 3 groups of 40 according to the shape of the tear, as Group A (crescent type), Group B (U type), and Group C (L type).
The mean age of the whole sample was 66.68 ± 6.86 years (range, 50–81 years). A statistically significant difference was determined between the groups in respect of constant murley (CM), American shoulder and elbow surgeons score (ASES), and University of California Los Angeles score (UCLA) scores (P < .05). The scores of Group A of all the scales were found to be higher than those of Group C (P < .05). In single row and double row repair of small and medium-sized tears of all shapes, no significant difference was determined in respect of the CM and UCLA scores (P > .05).
No significant difference was determined between single and double row repair of crescent type tears of all sizes. In large U-shaped tears, the CM, ASES, and UCLA scores were determined to be high in double row repair.

Abstract

Introduction:
Patients with coronavirus disease (COVID-19) may develop acute respiratory distress syndrome (ARDS). There have been few reports of postpartum woman with ARDS secondary to COVID-19 who required respiratory support using veno-venous extracorporeal membrane oxygenation (ECMO). We present the case of a 31-year-old woman who was admitted to hospital at 35 weeks gestation with ARDS secondary to COVID-19 and required ECMO during the postpartum period.

Patient concerns:
The patient had obvious dyspnea, accompanied by chills and fever. Her dyspnea worsened and her arterial oxygen saturation decreased rapidly.

Diagnosis:
ARDS secondary to COVID-19.

Interventions:
Emergency bedside cesarean section. Medications included immunotherapy (thymosin α 1), antivirals (lopinavir/ritonavir and ribavirin), antibiotics (imipenem-cilastatin sodium and vancomycin), and methylprednisolone. Ventilatory support was provided using invasive mechanical ventilation. This was replaced by venous-venous ECMO 5 days postpartum. ECMO management focused on blood volume control, coagulation function adjustment, and airway management.

Outcomes:
The patient was successfully weaned for ECMO and the ventilator and made a good recovery.

Conclusion:
Special care, including blood volume control, coagulation function adjustment, and airway management, should be provided to postpartum patients with ARDS secondary to COVID-19 who require ECMO support.

Abstract

Objective:
Alveolar soft part sarcomas (ASPS) which has high potential ability of metastasis, is a rare and slowly growing malignant tumor, and mainly primary localized in limbs. To date, little is known about the best treatment of ASPS. This study aims to review the current management and advance of ASPS.

Methods:
WANFANG MED ONLINE, CNKI, and NCBI PUBMED were used to search literature spanning from 1963 to 2020, and all cases of ASPS about “ASPS, diagnosis, treatment, surgery, radiotherapy, chemotherapy, target therapy or immune therapy” with detailed data were included.

Results:
Complete surgical resection remained the standard management strategy, radiotherapy was reported to be used for the patients of micro- or macroscopical incomplete residue or the surgical margin was questionable. Chemotherapy was controversial. Some target drugs and immune checkpoint inhibitors had produced antitumor activity.

Conclusion:
Complete surgical resection is the cure treatment for ASPS, and adjuvant chemotherapy is not recommended excepted clinical trials. For the patients with micro- or macroscopical incomplete residue, radiotherapy should be appreciated. Furthermore, for recurrence, distant metastasis, and refractory of ASPS, combination therapy, especially combination with multiple target agents and/or immune checkpoint inhibitors may prolong survival time.

Abstract
Infectious disease pandemics has a great impact on the use of medical facilities. The purpose of this study was to analyze the effects of coronavirus disease 2019 (COVID-19) on the use of emergency medical facilities in the Republic of Korea. This single-center, retrospective observational study was conducted in a tertiary teaching hospital located in Incheon Metropolitan City, Republic of Korea. We set the pandemic period as February 19, 2020 to April 18, 2020, and the control period was set to the same period in 2018 and 2019. All consecutive patients who visited the emergency department (ED) during the study period were included. Patients were divided into 3 groups according to age (pediatric patients, younger adult patients and older adult patients). The total number, demographics, clinical data, and diagnostic codes of ED patients were analyzed. The total number of ED patients in the pandemic period was lower than that in the control period, which was particularly pronounced for pediatric patients. The proportion of patients who used the 119 ambulances increased in all 3 groups (P
= .002, P < .001, and P = .001), whereas the proportion of patients who visited on foot was decreased (P
= .006, P < .001, and P = .027). In terms of diagnostic codes, a significant decrease was observed in the proportion of certain infectious or parasitic diseases (A00-B99), and respiratory diseases (J00-J99) in the pediatric and younger adult patient groups (P < .001 and P < .001, respectively). The COVID-19 pandemic reduced the number of ED patients; however, the proportion of patients using ambulances increased. In particular, the proportion of patients with diagnostic codes for infectious and respiratory diseases significantly decreased during the pandemic period.

Published: August 2021

Abstract

Background:
When the patients of advanced non-squamous non-small cell lung cancer (NSCLC) have achieved remission by induction therapy, it is controversial that combination with bevacizumab is used as maintenance therapy. Pemetrexed is a classic drug for maintenance therapy, is bevacizumab the superiority to pemetrexed is also unclear. This meta-analysis aims to evaluate the effectiveness and safety of advanced non-squamous NSCLC in the maintenance treatment.

Method:
From the establishment as of December 6, 2020, PubMed, Embase, and Cochrane electronic databases were searched and the American Society of Clinical Oncology, European Society of Medical Oncology, and National Comprehensive Cancer Network databases in the past 10 years. The application of combination with bevacizumab, pemetrexed was studied in clinical trials of maintenance treatment for advanced NSCLC. The extracted data include progression-free survival (PFS), overall survival (OS), and grade 3–4 adverse events (AE).

Results:
Seven clinical trials we screened, 6 were phase III RCTs, and a cohort trial, including 3298 patients. Compared with bevacizumab and pemetrexed, PFS of combination with bevacizumab was significantly improved (hazard ratio [HR] = 0.71, 95% confidence interval [CI] = 0.65–0.77, P < .00001), but OS was not improved (HR = 0.93, 95% CI = 0.85–1.01, P = .10). Compared with bevacizumab and pemetrexed, no significant difference of PFS (HR = 0.87, 95% CI = 0.69–1.09, P = .21), and OS (HR = 0.87, 95% CI = 0.72–1.05, P = .15) was found. A higher incidence of grade 3–4 AE occurred in combination with bevacizumab (odds ratio = 1.63, 95% CI = 1.35–1.97, P < .00001).

Conclusions:
PFS was significantly improved in patients with advanced non-squamous NSCLC who use bevacizumab combination with single-agent as maintenance treatment, but it does not translate into the advantages of OS; compared with bevacizumab, no PFS and OS benefits were found. A higher incidence of grade 3–4 AE occurred in combination with bevacizumab than pemetrexed and bevacizumab.
Potential value of tripartite motif-containing 59 as a biomarker for predicting the prognosis of patients with lung cancer
Authors: Guo Jianfei , Min Ke , Deng Lichun 
Published: August 2021

Abstract

Background:
In recent years, related studies have revealed that tripartite motif-containing 59 (TRIM59) is related to the prognosis of lung cancer. However, these results have not been proved by any evidence. Therefore, this study evaluated the relationship between TRIM59 and the prognosis of lung cancer by carrying out meta-analysis. In addition, we explored the mechanism and related pathways of TRIM59 in lung cancer through bioinformatics analysis.

Methods:
Comprehensive literature search was performed in China National Knowledge Infrastructure, Chinese Biomedical literature Database, Chinese Scientific and Journal Database, Wan Fang, Web of Science, PubMed, and EMBASE databases, and eligible studies were obtained based on the inclusion and exclusion criteria. The pooled hazard ratios and odds ratios were applied to assess the clinical value of TRIM59 expression for overall survival and clinicopathological features. Meanwhile, meta-analysis was conducted on the Stata 16.0. The mRNA expression level of TRIM59 in lung cancer was analyzed using Oncomine and Gene Expression Profiling Interactive Analysis (GEPIA) database. Gene Set Enrichment Analysis (GSEA) was used to predict the signaling pathways that TRIM59 might be involved in. The correlation between the expression level of TRIM59 in lung cancer and the abundance of immune cell invasion was analyzed by TIMER database. The survival analysis was verified by Kaplan–Meier Plotter database.

Results:
The results of this meta-analysis would be submitted to peer-reviewed journals for publication.

Conclusion:
In this study, the application of meta-analysis and bioinformatics analysis will provide evidence support for the study on the prognosis and mechanism of TRIM59 in lung cancer.
Effectiveness and safety of acupuncture in treating sleep disturbance in dementia patients
Authors: Kwon Chan-Young , Lee Boram , Ha Da-Jung 
Published: August 2021

Abstract

Background:
Dementia is of increasing importance, as it is a major public health problem worldwide. Sleep disturbance is common in dementia patients and may be associated with worse cognitive symptoms or behavioral and psychological symptoms of dementia. Non-pharmacological approaches, such as acupuncture, for treating this clinical condition are gaining importance. This study aimed to comprehensively search and analyze randomized controlled clinical trials (RCTs) of acupuncture in treating sleep disturbance or sleep disorders in dementia patients

Methods:
A comprehensive search was conducted from 12 electronic databases on December 2, 2020. We included RCTs reporting the effectiveness and safety of acupuncture in treating sleep disorders or disturbance in dementia patients. The methodological quality of the included studies was assessed using the Cochrane Collaboration's risk-of-bias tool.

Results:
Five articles with four original RCTs met the inclusion criteria. These studies reported clinical data suggesting that adjuvant acupuncture for hypnotics, and ear acupressure in dementia patients with sleep disorders or sleep disturbance may have clinical benefits in certain sleep-related parameters and total effective rate (TER). Only 1 study reported the safety profile of the intervention, and no acupuncture-related adverse reactions were reported. Some studies compared 2 kinds of acupuncture methods, and found that specific acupuncture methods were superior to conventional acupuncture in improving sleep-related parameters, cognitive function and TER. The methodological quality of the included clinical studies was not high.

Conclusions:
There were limited acupuncture studies on this topic. Given the number of studies included and their sample size, methodological quality, and heterogeneities, clinically relevant conclusions could not be drawn. Further clinical studies are needed in this field considering its urgency and importance.

Published: August 2021

Abstract
High tibial osteotomy (HTO) is a promising surgery that can treat osteoarthritis of the medial septum of the knee. However, the extensive release of soft tissue and the osteotomy gap may produce intraoperative and postoperative bone bleeding. Tranexamic acid (TXA) is an effective blood management strategy, as it competitively inhibits the activation process of plasminogen and prevents fibrinolytic enzymes from degrading fibrin. Therefore, we compared the operative bone bleeding of patients who underwent HTO who received either intravenous (IV) or topical TXA in this research.
The medical records of a total of 191 patients (including 72 who received IV TXA, 64 who received topical TXA and 55 control patients) who received open-wedge HTO were retrospectively reviewed from January 2016 to August 2019. There were no obvious demographic differences between the groups. Here, we used independent parameters to assess the efficacy of topical and IV TXA in reducing blood loss.
Compared with the IV TXA group, patients receiving topical TXA therapy had greater blood loss (622 ± 231 ml versus 451 ± 231 ml, mean difference 171 mL [95% CI, 87–254]; p < 0.001). The hemoglobin concentration of the IV TXA group was obviously higher than that of the topical medication group. No patients had thromboembolic complications during the entire study period.
In our study, it seemed that either IV or topical use of TXA might reduce blood loss after open-wedge HTO, and the blood loss and amount of drainage in the IV TXA group showed huge decreases compared to those in the topical group.

Abstract
Idiopathic flatfoot is common in infants and children, and patients with this condition are frequently referred to pediatric orthopedic clinics. Flatfoot is a physiologic process, and that the arch of the foot elevates spontaneously in most children during the first decade of life. To achieve a consensus as the rate of spontaneous improvement of flatfoot, the present study aimed to estimate the rate of spontaneous improvement of flatfoot and to analyze correlating factors.
We reviewed the records of patients examined between May 2013 and May 2019 so as to identify those factors associated with idiopathic flatfoot below 12 years of age. We included patients with who had been followed for >6 months, and those for whom ≥2 (anteroposterior and lateral) weight-bearing bilateral radiographs of the foot had been obtained. The progression rates of the anteroposterior (AP) talo-first metatarsal angle, talonavicular coverage angle, lateral talo-first metatarsal angle, and calcaneal pitch angle were adjusted by multiple factors using a linear mixed model, with sex, body mass index, and Achilles tendon contracture as the fixed effects and age and each subject as the random effects.
We found that 4 of the radiographic measurements improved as patients grew older. The AP talo-first metatarsal angle, talonavicular coverage angle, and the lateral talo-first metatarsal angle decreased, while the calcaneal pitch angle increased. The AP talo-first metatarsal angle (P < .001), talonavicular coverage angle (P < .001), and lateral talo-first metatarsal angle (P < .001) improved significantly; however, the calcaneal pitch angle (P = .367) did not show any significant difference. In general, the flatfeet showed an improving trend; after analyzing the factors, no sex difference was observed (P = .117), while body mass index (P < .001) and Achilles tendon contracture (P < .001) showed a negative correlation.
The study demonstrated that children's flatfeet spontaneously improved at the age of 12 years. It would be more beneficial if the clinician shows the predicted appearance of the foot at the completion of growth by calculating the radiographic indices and identifying the correlating factors in addition to explaining that flatfoot may gradually improve. This will prevent unnecessary medical expenses and the psychological adverse effects to the children caused by unnecessary treatment.

Abstract
The hospice and palliative care can improve the symptoms and signs of terminal cancer patients. The purposes of this study are how to improve terminally ill cancer patients’ symptoms and signs and how the dedicated palliative care service effects on these improvements.
From January 2017 to March 2019, among 919 terminally ill cancer patients admitted to the palliative care units in 11 hospitals of South Korea, we analyzed 334 patients with prospective cohort method and categorized them into non-dedicated hospice care group of 234 and dedicated hospice care group of 100.
Symptoms improvement of dyspnea, fatigue, drowsiness, and dry mouth during the first week of admission were respectively 298 (89.2%), 25 (7.5%), 204 (61.1%), 76 (22.8%). Signs improvement of myoclonus, respiratory secretion, leg edema, and ascites between admission and a week after were 5 (1.5%), 41 (12.3%), 47 (14.1%), 12 (3.6%). Significant differences between dedicated hospice care physician group and non-dedicated hospice care physician group were shown in drowsiness (67.5% vs 46%, P < .001) and respiratory secretion (15% vs 6%, P < .028). Compared to non-dedicated care group, the odds ratio for more than 2 symptoms or signs was 1.78 (95% confidence interval, 1.05–3.02) in the dedicated care group after adjusting confounding variables.
In conclusion, terminally ill cancer patients who received palliative or hospice service showed significant improvement in symptoms and signs. And, family doctors (dedicated hospice physician group) performed better than oncologists (non-dedicated physician group).

Abstract
Asian Indians have a genetic predisposition to atherothrombotic risk. common carotid intima-media thickness (CCIMT) measured by ultrasound is a quantitative marker for atherosclerotic burden and a derived variable, that is, “CCIMT statistical Z-score (Z-score)” is useful for better quantification. The association between vitamin D deficiency and atherosclerosis is inconclusive. Since, vitamin D deficiency is highly prevalent in India, there is a need to study its relative contribution to subclinical atherosclerotic burden.
This prospective cross-sectional study (n = 117) in apparently healthy individuals aged 20 to 60 years sought to identify the determinants of CCIMT Z score with CCIMT measured by “echo-tracking” method. A multivariable linear regression analysis was done with CCIMT Z score as dependent variable and the following as independent variables: age, body mass index, waist-to-height ratio, total cholesterol to HDL ratio (TC-HDL ratio), serum vitamin D3 levels (ng/mL), sex, diabetes mellitus, current cigarette smoking status. A diagnostic prediction model was also developed with a threshold value of 1.96 for CCIMT Z score.
The mean (SD) for calendar age (y) was 40 (8). There were 26 (22.22%) individuals in sample with CCIMT Z score ≥1.96 (advanced stage) of whom 14 (23.33%) were <40 y (n = 60). The mean score was 1.28 (90th percentile) in the entire sample. Vitamin D3 deficiency with a mean (SD) blood level (ng/mL) of 14.3 (6.4) was noted and prevalence of deficiency was 81%. The final model was
CCIMT Z-score = 0.80 +  (0.841 × current smoking = 1) + (0.156 × TC-HDL ratio) – (0.0263 × vitamin D3 blood level in ng/mL).
The decreasing order of association is smoking, TC-HDL ratio, and vitamin D3. With the model, likelihood ratio (95% CIs) was better for positive test 3.5 (1.23–9.94) than that for a negative test 0.83 (0.66–1.02).
Internal validation with Bootstrap resampling revealed stability of baseline diagnostic variables.
There is substantial subclinical atherosclerotic burden in Indian setting with independent contribution by vitamin D deficiency. The model is valuable in “ruling-in” of the underlying advanced atherosclerosis. The study is limited by convenient sampling and lack of external validation of the model.
