Abstract

Background
Few studies about the evolutionary history of the hepatitis E virus (HEV) have been conducted. The aim of our work was to investigate and make inferences about the origin and routes of dispersion of HEV-3 in Argentina.

Methods
Phylogenetic, coalescent and phylogeographic analyses were performed using a 322-bp ORF2 genomic fragment of all HEV-3 sequences with known date and place of isolation published at GenBank until May 2018 (n=926), including 16 Argentinian sequences (isolated from pigs, water and humans).

Results
Phylogenetic analysis revealed two clades within HEV-3: abchij and efg. All Argentinian samples were grouped intermingled within clade 3abchij. The coalescent analysis showed that the most recent common ancestor for the clade 3abchij would have existed around the year 1967 (95% highest posterior density (HPD): 1963–1970). The estimated substitution rate was 1.01×10−2 (95%HPD: 9.3×10ˉ3–1.09×10ˉ2) substitutions/site/y, comparable with the rate previously described. The phylogeographic approach revealed a correspondence between phylogeny and place of origin for Argentinian samples, suggesting many HEV introductions in the country, probably from Europe and Japan.

Conclusions
This is the first evolutionary inference of HEV-3 that includes Argentinian strains, showing the circulation of many HEV-3 subtypes, obtained from different sources and places, with recent diversification processes.

Resource Passageways and Caravans: A Multi-level, Multi-disciplinary Review of the Antecedents of Resources over the Lifespan
Authors: Sarandopoulos Lee , Bordia Prashant 
Published: February 2021

Abstract
Resources are vital for older worker effectiveness and well-being, yet limited attention has been paid to the antecedents of resources. Drawing together the rich cross-disciplinary literature on resources, and through the lens of cumulative disadvantage and resource passageways, we review the individual, organizational, and institutional factors that influence the resources available to people in late working life. The review provides a more nuanced perspective on older workers as agentic actors. We highlight how agency can be constrained via a person’s resources, which are shaped by structural influences. Knowledge of structural influences on resources is important for understanding the experiences of older workers and their continued effectiveness in the work domain. We outline avenues for future research on resources and aging at work that incorporates these multi-level influences.

Abstract

Objective:
To examine whether blood pressure (BP) accelerates more rapidly during the menopause transition for women with a history of preterm or term small for gestational age (SGA) delivery compared to women with all term and appropriate for gestational age (AGA) births.

Methods:
A longitudinal analysis was conducted with 1,008 parous women who had BP data at ≥2 study visits. We used generalized linear modeling to examine BP before the final menstrual period, at the final mentrual period, and up to 10 years after the final menstrual period, according to pregnancy group. We assessed maternal changes in BP over time in relation to years near the final menstrual period using a piece-wise linear model, consistent with menopause-induced changes. Models were adjusted for socio-demographics, body mass index, smoking, physical activity, medications, parity, age at first birth, gestational diabetes, and gestational hypertension/preeclampsia.

Results:
At baseline, women were on average 46 years old, 101 (10%) reported a prior preterm birth, and 102 (10.1%) reported a term SGA birth. Compared to women with all term AGA births, women with a term SGA birth had higher BP before the final menstrual period, at the final menstrual period, and up to 10 years after the final menstrual period; women with a preterm birth had higher BP in the postmenopausal years. Annual rate of change in BP during the menopause transition did not differ between pregnancy groups.

Conclusions:
Women with a history preterm and term SGA delivery have higher BP than women with all term AGA births during the menopause transition, but rate of change in BP does not differ in these groups relative to final menstrual period.

Abstract
To retrospectively analyze the computed tomography (CT) findings and clinical manifestations of gastric calcifying fibrous tumor (CFTs).
The features of 7 cases with pathologically proven gastric CFTs who had undergone CT were assessed, including tumor location, contour, growth, degree of enhancement, calcification and clinical data. In addition, the size and CT value of each lesion were measured. The mean values of these CT findings and clinical data were statistically analyzed only for continuous variables.
Four patients were female and three were male (mean age: 33.3 years; range: 22 ∼ 47 years). Nonspecific clinical symptoms: abdominal pain and discomfort were observed in four cases and the CFTs were incidentally detected in the other three cases. Regarding tumor markers, lower ferritin levels were observed in three female patients. All of the gastric CFTs were solitary and mainly located inside the body; they were in round or oval shape and exhibited endophytic growth. Gastric CFTs are usually small sized and could contain confluent and coarse calcifications; cyst, necrosis, ulcer, bleeding and surrounding lymphadenopathy were not found in any of the cases. Unenhanced CT values of gastric CFTs were higher than those of same-transect soft tissue. Mild-to-moderate enhancement in the arterial phase and progressive enhancement in the portal venous phase were mainly noted.
A gastric mass with a high unenhanced CT attenuation value, confluent and coarse calcifications and mild-to-moderate enhancement could prompt a diagnosis of gastric CFT. In addition, (1) being young- or middle-aged, (2) having relatively low ferritin levels, and (3) tumor located in the gastric body have critical reference value for diagnosis of gastric CFT.

Abstract
Brain natriuretic peptide is an established, surrogate follow-up marker, strongly correlated with heart failure severity. Several other biomarkers and tests are useful for assessing the prognosis of patients with HF, such as oxidized low-density lipoprotein antibodies and C-reactive protein. Some inflammatory cells, including monocytes, lymphocytes, and neutrophils, are involved in coronary heart disease and may be useful for prognosis also. This study assessed the potential usefulness of various laboratory biomarkers in predicting long-term outcomes and hospitalization among a cohort of outpatients with chronic, advanced HF.
This retrospective, 18-year follow-up study included all patients admitted to the Heart Failure Outpatient Unit in our tertiary care medical center from 2000 through 2001 due to chronic HF. Excluded were patients with malignant disease, severe stroke, active inflammatory disease, or infection. At the first visit, blood was sampled for routine analysis and biomarkers NT-proBNP, C-reactive protein, myeloperoxidase, heat shock protein, and antibodies to oxidized low density lipoprotein. left ventricular ejection fraction and New York Heart Association class class were also established. Patients were followed every 3 months. Study endpoints were mortality or first hospitalization.
Among 305 study patients, HF duration ranged from 2 months to 18 years. Mean follow-up was 9.1 ± 6 years. Mean time to first hospitalization was 60 ± 58.1 months, median = 38 (range 0–179). Mortality rate was 41%. Regression analysis showed New York Heart Association class, lymphocyte count and alkaline phosphatase were independent predictors of survival, with hazard ratios of 1.0, 0.973, and 1.006, respectively (P < .05).
N-terminal pro-B-type natriuretic peptide, alkaline phosphatase, and lymphocyte count are important prognostic predictors for very long-term follow-up among patients with chronic HF.

Abstract
Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) significantly improve outcomes of patients with EGFR-mutated non-small-cell lung cancer (NSCLC). However, acquired resistance inevitably emerges and remains a major challenge. The present study aimed to evaluate the efficacy of EGFR-TKIs plus bevacizumab in advanced non-squamous NSCLC patients with gradual progression on EGFR-TKIs.
Advanced non-squamous EGFR-mutated NSCLC patients with gradual progression on EGFR-TKIs were administered bevacizumab while EGFR-TKIs were continued until disease progression occurred. Tumor lesions were assessed, and blood samples were collected at the start of the combination treatment and every 6 weeks until disease progression.
Among the 15 included patients, there were no grade 3 or higher adverse events (AEs). Partial response (PR) and stable disease (SD) were achieved in 1 and 13 patients, respectively, with an objective response rate (ORR) of 6.7% and a disease control rate (DCR) of 93.3%. The median progression-free survival 2 (PFS2), defined as the time from the initiation of combination treatment to disease progression, was 5.0 (95% confidence interval [CI]: 4.0–6.0) months. Additionally, Spearman correlation analysis revealed that PFS2 was positively correlated with the serum vascular endothelial growth factor (VEGF) level at baseline (r = 0.7212, P = .0234). Patients with high baseline serum VEGF levels showed a better median PFS2 than those with low baseline serum VEGF levels (5.5 months vs 3.6 months, P = .0333).
EGFR-TKIs plus bevacizumab led to a durable prolongation of PFS in non-squamous NSCLC patients with gradual progression on EGFR-TKIs. This therapeutic regimen was well tolerated and could be a promising strategy for these patients. Serum VEGF could be a potential biomarker to predict a subset of patients who are likely to benefit from EGFR-TKIs combined with bevacizumab.

Published: February 2021

Abstract

Background:
In the past few decades, the number of surgery of anterior cruciate ligament reconstruction (ACLR) implemented in the outpatient centers has dramatically enhanced. There is still a lack of effective randomized controlled trials in the literature to demonstrate the effectiveness of tourniquets. As a kind of prospective clinical trial, this research protocol is conducted to compare the results of ACLR with and without the use of a tourniquet.

Methods:
All the patients aged 18 or over who underwent the selective primary anterior cruciate ligament reconstruction in our hospital from November 2020 to January 2022 are eligible to take part in our experiment. Exclusion criteria are history of peripheral neuropathy, pregnancy, lumbar radiculopathy, or surgery to the injured or contralateral knee. After the written informed consent is given, the patients participating in the study are randomly assigned to the tourniquet group (group 1) and the tourniquet free group (group 2) on the day of operation, through utilizing the computer-generated random table with 10 members in each group. And the assignments were kept in an opaque and sealed envelope. Any comments on visual difficulties in the process of operative time, arthroscopy, complications, and total bleeding from suction and drainage, as well as the reduction of postoperative hemoglobin are assessed as the parameters. The software of SPSS v. 24 is applied for all the statistical analyses.

Results:
This protocol will provide a reliable theoretical basis for the following research.

This study protocol was registered in Research Registry (researchregistry6240).
Identification of an 11-lncRNA signature with high performance for predicting the prognosis of hepatocellular carcinoma using bioinformatics analysis
Authors: Wang Anmei , Lei Junhua 
Published: February 2021

Abstract
Hepatocellular carcinoma (HCC) is a common primary liver cancer with a high incidence and mortality. This study was conducted to identify a long non-coding RNA (lncRNA) signature that may serve as a predictor for HCC prognosis.
RNA-seq data were extracted from The Cancer Genome Atlas database. Differentially expressed genes, lncRNAs, and miRNAs were identified in HCC (n = 374) and control samples (n = 50) and used to screen prognosis-associated lncRNA signatures. The association of the lncRNA signature with HCC prognosis was analyzed and a competitive endogenous RNA regulatory network involving the lncRNA signature was constructed.
A total of 199 mRNAs, 1092 lncRNAs, and 251 miRNAs were differentially expressed between HCC and control samples. Among these lncRNAs, 11 prognosis-associated lncRNAs were used to construct a lncRNA signature. Cox regression analysis showed that patients with higher risk scores of the lncRNA signature were at risk of poor prognosis. Four lncRNAs (including LINC01517, DDX11-AS1, LINC01136, and RP11-20J15.2) and 7 miRNAs (including miR-195, miR-199b, miR-326, miR-424, and let-7c) in the ceRNA network interacted with the upregulated gene E2F2, which was associated with the overall prognosis of patients with HCC.
The 11-lncRNA signature might be useful for predicting the prognosis of patients with HCC.
Extracorporeal shock wave therapy for treating primary dysmenorrhea
Authors: Xing Ruirui , Yang Jian , Wang Renwei , Wang Yan 
Published: February 2021

Abstract

Background:
There are scanty data to apply radial extracorporeal shock wave therapy (rESWT) on the acupuncture points in the lower abdomen to reduce the menstrual pain. This trial aimed to test the rESWT safety and efficacy for treating primary dysmenorrhea (PD).

Methods:
Forty-four young-women with PD were randomly assigned to one of the three groups: to receive rESWT on the acupuncture points during the follicular phase (Group A, n = 15) or during the luteal phase (Group B, n = 14), or to apply heat patch to the acupuncture points during the follicular phase as the control (Group C, n = 15) over three menstrual cycles. The pain severity (using 0-to-10 visual analog scale), the pain duration (hours), plasma PGF2α prostaglandin F2alpha and prostaglandin E2 (PGE2), self-rating anxiety scale and menstrual blood loss were assessed before and after interventions.

Results:
The pain severity and duration significantly decreased in all groups after interventions. Although the reduced pain duration was not different among the groups, the reduced pain severity was more significant (P = .003) in Groups A (−53.8 ± 33.7%) and B (−59.3 ± 36.7%) than in Group C (−18.7 ± 27.1%). The rESWT intervention did not change plasma prostaglandins in Group A, although there was a decreased prostaglandin F2alpha (−20.5 ± 32.9%) in Group B or a decreased PGE2 (-18.9 ± 17.8%) in Group C. The anxiety level showed no change after intervention. The menstrual blood volume reduced slightly after intervention and the change of menstrual blood loss in Group B was significant (P = .038).

Conclusion:
The rESWT applications on the abdominal acupuncture points safely and effectively reduced the menstrual pain, which was not associated with the prostaglandin changes. The rESWT-reduced pain seemed equally effective with the intervention applied during the follicular phase or luteal phase of the menstrual cycle. Heat patch placed on the abdominal acupuncture points also reduced the pain severity and duration, indicating that the improved blood flow could effectively alleviate the menstrual pain with PD. The changes in anxiety level and menstrual blood loss were slight after intervention.

Published: February 2021

Abstract
Dermoscopy is a noninvasive diagnostic technique that is of great value for the differential diagnosis of palmoplantar psoriasis and palmoplantar eczema. Considering the particularity of palmoplantar anatomy, the dermoscopic features of psoriasis and eczema in palm region show fewer differences, compared with those in other parts of the body. Only a few studies have examined the palmoplantar region of psoriasis and eczema patients under a dermoscope.
A total of 26 patients with palmoplantar psoriasis and 31 patients with palmoplantar eczema were enrolled in our study. Target palmoplantar areas were observed through general observation and under dermoscope.
We found that the presence of white scales and a regular arrangement of dots and globular vessels were significantly indicative of palmoplantar psoriasis, while yellowish scales and an irregular arrangement of atypical vessels were significantly indicative of palmoplantar eczema.

Published: February 2021

Abstract

Background:
Presentation of musculoskeletal symptoms, such as pain, discomfort, or disability, caused by a traffic accident (TA) is a common occurrence. However, studies on treatment and management of sudden low back pain (LBP) caused by a TA are very scarce, while studies on the effectiveness of motion style acupuncture therapy (MSAT) used on such patients are also rare. Accordingly, a randomized controlled trial (RCT) is planned to assess the effectiveness and safety of MSAT using traction (T-MSAT) for the treatment of pain and functional problems in patients with acute LBP caused by a TA.

Methods:
This study will be conducted at Jaseng Hospital of Korean Medicine in South Korea, using a two-armed, parallel, assessor-blinded RCT design. The study population will consist of 100 participants who will be randomly assigned in a 1:1 ratio to either the T-MSAT+integrative Korean medicine therapy (IKMT) group or IKMT control group. The treatment will be applied continuously for 3 days after admission. The primary outcome will be the difference between the numeric rating scale (NRS) scores at admission and immediately after treatment on the fourth day of admission. Secondary outcomes will include visual analogue scale (VAS) for LBP and radiating leg pain; NRS for radiating leg pain; lumbar active range of motion; Oswestry Disability Index (ODI); Patient Global Impression of Change (PGIC); the Post-traumatic Stress Disorder Checklist for DSM-5 (PCL-5-K); and 12-item short-form health survey (SF-12).

Discussion:
This study is a RCT to assess the effectiveness and safety of T-MSAT for acute LBP caused by a TA. The findings could be used by healthcare-related policy makers and clinicians in primary care institutions, which are frequently visited by patients suffering from LBP caused by a TA.

Abstract
Although the incidence of oral cavity cancer (OCC) in young never smoker females is increasing worldwide, there has been little research on the etiologies and characteristics of these patients to date. In this study, we sought to evaluate the annual increase in OCC incidence in young never smoker females (YNSF) in our hospital as well as to investigate their clinicopathological characteristics and different disease courses compared with those of other OCC patients. We retrospectively reviewed the medical records of patients who were diagnosed and treated at our tertiary referral hospital from 2006 to 2016. The annual incidence of OCC and proportion of YNSF (never smoker females aged 45 years or younger at the time of diagnosis) among the enrolled OCC patients were evaluated. The characteristics and prognosis of the YNSF group were analyzed using their clinicopathological and survival data. Among the OCC patients primarily enrolled in this study, the proportion of YNSF did not show significant annual increase. There were 32 YNSF among 354 OCC patients (9%), who were ultimately included for the analyses of clinicopathological characteristics and survival. However, YNSF showed no significant differences compared with other OCC patients, even in subgroup analyses for overall survival. Our study did not demonstrate significant changes in the annual proportion of YNSF among OCC patients. In addition, differences in neither clinicopathological characteristics nor survival were noted between YNSF and other OCC patients.
