Abstract
Hypersensitivity due to central pain mechanisms can influence recovery and lead to worse clinical outcomes, but the ability of quantitative sensory testing (QST), an index of sensitisation, to predict outcomes in chronic musculoskeletal disorders remains unclear. We systematically reviewed the evidence for ability of QST to predict pain, disability, and negative affect using searches of CENTRAL, MEDLINE, EMBASE, AMED, CINAHL, and PubMed databases up to April 2018. Title screening, data extraction, and methodological quality assessments were performed independently by 2 reviewers. Associations were reported between baseline QST and outcomes using adjusted (β) and unadjusted (r) correlations. Of the 37 eligible studies (n = 3860 participants), 32 were prospective cohort studies and 5 randomised controlled trials. Pain was an outcome in 30 studies, disability in 11, and negative affect in 3. Meta-analysis revealed that baseline QST predicted musculoskeletal pain (mean r = 0.31, 95% confidence interval [CI]: 0.23-0.38, n = 1057 participants) and disability (mean r = 0.30, 95% CI: 0.19-0.40, n = 290 participants). Baseline modalities quantifying central mechanisms such as temporal summation and conditioned pain modulation were associated with follow-up pain (temporal summation: mean r = 0.37, 95% CI: 0.17-0.54; conditioned pain modulation: mean r = 0.36, 95% CI: 0.20-0.50), whereas baseline mechanical threshold modalities were predictive of follow-up disability (mean r = 0.25, 95% CI: 0.03-0.45). Quantitative sensory testing indices of pain hypersensitivity might help develop targeted interventions aiming to improve outcomes across a range of musculoskeletal conditions.

Objective:
The aim of this study is to investigate the current status of the diagnosis and treatment of patients with pancreatic neuroendocrine neoplasms (pNENs) undergoing surgery in China.

Methods:
This is a multicenter cross-sectional study performed in China. Data from patients with pNENs undergoing surgery at 33 high-volume medical centers, where the number of pancreatectomies exceeds 20 cases per year, were collected and analyzed between March 1, 2016 and February 28, 2017.

Results:
In total, 392 patients with pNENs were enrolled. The male to female ratio was 1.4. The majority of patients were aged between 40 and 70 years. 65.6% of the patients had non-functional tumors. Among those with functional tumors, the percentages of insulinomas, gastrinomas, glucagonomas, and vasoactive intestinal peptide-secreting tumors were 94.8%, 1.5%, 2.2%, and 1.5%, respectively. Multidisciplinary team (MDT) discussion was conducted for 39.0% of the patients. Minimally invasive surgery was performed on 31.1% of the 392 patients. The incidence of grade B/C pancreatic fistula formation was 4.4%. A total of 89.0% of the surgeries achieved R0 resection, and 41.6% of the tumors were well differentiated. Lymph node metastasis was present in 8.9% of the patients. The percentages of patients with grades G1, G2, and G3 disease were 49.2%, 45.7%, and 5.1%, respectively.

Conclusion:
This multicenter cross-sectional study systematically presents the current status of the diagnosis and treatment of patients with pNENs undergoing surgery in China. MDT consultation for pNENs has not been widely implemented in China. Although the incidence of surgical complications is relatively low, minimally invasive procedures should be further promoted. This study shows us how to improve the outcomes of these patients.

Abstract
While it is important to treat lifestyle-related diseases for the primary and secondary prevention of cardiovascular diseases, medication adherence is still poor. Although various causes of poor adherence have been reported, the differences between physicians and their patients regarding the recognition of medication adherence have not been well-investigated.
We administered a questionnaire about medication adherence to 300 outpatients and their 23 cardiologists at the Department of Cardiology, Fukuoka University Hospital. The questionnaires for patients and physicians included acceptable total number of drug doses and dosing schedule, forgetting to take the medicine, and dose-reduction or -increase based on self-judgement. The patients were 70.6 ± 12.3 years old and 61.0% (n = 183) were male. Patients reported that it was acceptable to receive 0–5 doses twice daily. The patients were divided into two groups: an agreement group, in which physicians and their patients had the same answer to the question regarding forgetting medication (203 cases; 67.7%), and a disagreement group (97 cases; 32.3%). Overall, the inter-rater agreement between physicians and patients with regard to forgetting medication was significant, but slight (κ coefficient = 0.12). In a multivariate analysis, absence of hypertension [odds ratio (OR): 0.21, 95% confidence interval (CI): 0.09–0.50, P < .001), β-blocker usage (OR: 1.86, 95% CI: 1.11–3.12, P = .02), and biguanide usage (OR: 4.04, 95% CI: 1.43–11.41, P = .01) were independent predictors of disagreement with regard to forgetting medication.
The inter-rater agreement between physicians and patients with regard to medication adherence was slight. An increase in inter-rater agreement should improve medication adherence.

Abstract
Patients with inflammatory bowel disease have an increased risk of vitamin D deficiency and this may impact upon the disease activity. This study explored the association between serum vitamin D levels and inflammatory bowel disease in a Chinese population.
Sixty-five patients with ulcerative colitis (UC) and 50 with Crohn's disease (CD) were investigated between January 2015 and December 2016 at the Kunshan Second People's Hospital, China. A control group of 120 healthy volunteers was also selected. Serum vitamin D levels were detected and compared between groups and among patients with different disease activity.
The serum vitamin D levels in the UC (10.27 ± 4.05 ng/mL) and CD (11.13 ± 3.96 ng/mL) groups were lower than in the control group (12.96 ± 5.18 ng/mL) (P < .05). In the UC group, during the moderate (9.21 ± 3.26 ng/mL) and severe (7.58 ± 3.81 ng/mL) periods, serum vitamin D levels were significantly lower compared with during remission (12.18 ± 3.69 ng/mL) and the mild period (11.35 ± 4.08 ng/mL) (P < .05). In the CD group, serum vitamin D levels were significantly lower during the moderate (10.28 ± 3.57 ng/mL) and severe (8.52 ± 3.72 ng/mL) periods compared with remission (13.97 ± 5.61 ng/mL) (P < .05).
Patients with UC and CD are both prone to vitamin D deficiency. Serum vitamin D was significantly lower with aggravating disease status. Therefore, vitamin D may be involved in the development of inflammatory bowel disease in a Chinese population.
Plasma exchange improves outcome of sepsis-associated liver failure
Authors: Ye Xiaolin , Wang Fei , Ding Yueping , Ma Dannv , Lv Bin 
Published: May 2019

Abstract

Rationale:
Sepsis-associated liver failure is characterized by increased bilirubin levels and coagulation disorders, which has a significant impact on mortality due to the insufficient understanding of its complicated pathogenesis pathophysiology and a lack of standardized treatment.

Patient concerns:
A 56-year-old woman presented signs of sepsis on the 2nd day after undergoing ureteroscopy for left ureter and laparoscopy for lysis of adhesions around left ureter due to hydronephrosis. Her condition seemed to have been improved after treatment, but the bilirubin levels suddenly increased drastically with presence of coagulation disorders.

Diagnosis:
Laboratory tests combined with her medical history confirmed the diagnosis as sepsis-associated liver failure.

Interventions:
Plasma exchange was applied after hepatoprotective drugs, and other supportive therapies were given which did not significantly improve the condition.

Outcomes:
Laboratory liver function tests indicated the restoration of damaged liver function after plasma exchange was performed and the patient was soon transferred from intensive care unit back to the general ward.

Lessons:
Plasma exchange might be a vital and effective therapy to improve outcome of sepsis associated liver failure especially when conventional support therapy is ineffective.

Abstract
There is scarce evidence regarding the association between the consumption of vegetables and fruits and depressive symptoms in Chinese population. The purpose of this study was to ascertain the influence of vegetables and fruits consumption on depressive symptoms in a middle-aged Chinese population. This study comprised 1676 Chinese adults aged between 45 and 59 years, who participated in a Health Survey at the time of periodic checkup in the city of Linyi, Shandong Province, China. Dietary intake was assessed using a semi-quantitative food frequency questionnaire (FFQ). Depressive symptoms were assessed using the Center for Epidemiological Studies Depression (CES-D) scale. Log-binomial regression analysis was used to evaluate the association between the consumption of vegetables and fruits and depressive symptoms. A total of 53 participants (3.2%) were classified as having depressive symptoms. After adjustment for confounding variables, participants in the highest quartile of the fruits consumption and vegetables consumption had lower prevalence ratio (PR) for depressive symptoms (PR = 0.76; 95% confidence interval [CI]: 0.603–0.974, P = .042; PR = 0.77; 95% CI: 0.612–0.977, P = .045) than those in the lowest quartile. Moreover, those in the highest quartile of total vegetables and fruits consumption had also a lower PR of depressive symptoms (PR = 0.67; 95% CI: 0.503–0.806, P = .037) than did those in the lowest quartile.
Our findings indicate that higher consumption of vegetables and fruits is significantly associated with a lower risk of depressive symptoms. Further prospective studies are needed to confirm these findings.
Hepatitis B virus prevalence and risk factors in hard-to-reach Turkish population living in Belgium

Published: May 2019

Abstract

Background:
Hepatitis B virus (HBV) infection is an important public health problem in the Turkish population, that is, one of the largest migrant populations in Europe. With the introduction of cost-effective antiviral treatments in the past decade, there is a need to identify HBV-infected patients who may benefit from treatment. This study describes the design of a study to assess the HBV prevalence in the Turkish population living in Belgium. Additionally, we will determine the risk factors of HBV infection and the uptake of screening, vaccination, and antiviral treatment in this hard-to-reach Turkish population.

Methods:
A longitudinal, epidemiological study will be conducted in the region Middle Limburg Belgium, where the Turkish adult population, 18 years of age and older, will be screened for hepatitis B surface antigen (HBsAg), antibodies against HBsAg (anti-HBs), and antibodies against hepatitis B core antigen (anti-HBc). Educational meetings concerning viral hepatitis B will be organized and there will be 3 ways to be screened for HBV: immediately after the educational meetings, at the Outpatient Hepatology Department of Ziekenhuis Oost-Limburg, and at home visits. Subsequently, participants will be asked to fill in a questionnaire regarding sociodemographic factors, migration history, risk factors for HBV infection (e.g., sharing toothbrushes, HBV-infected family member), and HBV vaccination status. Six months after screening, HBsAg-positive patients will be assessed whether they are under follow-up at the general practitioner or hepatologist. We will also gather information regarding the uptake of vaccination in nonimmunized subjects.

Discussion:
This study will provide information about the HBV prevalence and distribution of the stages of liver disease in the Turkish population in Belgium. By determining the risk factors for HBV infection, subgroups with an increased prevalence of HBV infection can be identified.

Clinical trial number:
This clinical trial is registered at clinicaltrials.gov (NCT03396458).
Respiratory viral infection in early life and development of asthma in childhood
Authors: Hassan Md Zakiul , Chowdhury Muhammad Abdul Baker , Hassan Imran , Chowdhury Fahmida , Schaefer Nancy , Chisti Mohammod Jobayer 
Published: May 2019

Abstract

Background:
Respiratory viruses are the leading cause of early life wheezing that may contribute to the development of childhood asthma leading to increasing morbidity and socioeconomic burden. The aim of this review is to identify whether respiratory viral infections during first year of life were associated with development of childhood asthma.

Methods:
We will search major scientific databases (MEDLINE, CINAHL, Web of Science, Cochrane Library, and ClinicalTrials.gov) using truncated and phrase-searched keywords and relevant subject headings. Observational studies including case–control studies, cohort studies, and randomized control trials published in English will be included in this review. Case reports, qualitative studies, and narrative overviews will be excluded. Exposure will be defined as laboratory-confirmed viral respiratory tract infection in the first year of life and outcome will be defined as development of asthma between ages 5 and 18 years. Effect sizes in bivariate and multivariate analyses will be presented as odds or prevalence ratios. We will explore for heterogeneity of the standard errors across the studies, and if appropriate, we will perform a meta-analysis using a random-effects model to present a summary estimate of the odds or prevalence ratios.

Results:
This review will assess whether respiratory viral infections during first year of life increases the risk of childhood asthma development.

Conclusions:
This systematic review will evaluate published literature, assessing the link between early life viral infection and childhood asthma. Pooled data may provide evidence that infantile respiratory viral infection results in higher incidence of recurrent wheezing and asthma, thereby stimulating further research into the cost-effectiveness of pharmaceutical interventions such as vaccines and nonpharmaceutical interventions such as hand-washing and respiratory hygiene promotion to young children. Implementing the results of such research may then reduce the burden of acute viral respiratory infections and subsequent recurrent wheezing and asthma.

Systematic review registration:
This systematic review has been registered on PROSPERO (CRD42018105519)
Clinical characteristics and prognosis of nonsurgically treated patients with pneumonic-type adenocarcinoma

Published: May 2019

Abstract
Pneumonic-type adenocarcinoma (P-ADC) is a subtype of lung adenocarcinoma with high mortality, which often requires lobectomy surgery. Nonsurgically treated P-ADC patients usually have more advanced or complex conditions, which remain poorly understood and pose a major challenge in clinical management. We aimed to describe the clinical profiles and prognosis of non-surgically treated P-ADC patients. We enrolled 71 patients with pathologically proven P-ADC from a university hospital in China. Clinical and laboratory data were retrieved from medical record. Their median age was 62 years, including 45% men and 35% smokers. Clinical manifestations were dominated by cough, sputum, and dyspnea. Main chest imaging features included nodules, shadow, consolidation, and air bronchogram. Nearly half or more of patients showed higher levels of inflammation and cancer biomarkers including cytokeratin-19-fragment (CYFRA 21-1) and carcinoembryonic antigen (CEA). Majority of patients were classified at the stage IIIB or IV. Palliative care was the most popular treatment option but provided a shorter overall survival compared to tyrosine kinase inhibitor therapy, standard chemotherapy, and sequential therapy while there were no significant differences in the survival among the latter 3 options. Higher serum CEA was associated with longer survival and better prognosis while higher serum CYFRA 21-1 could predict a poor prognosis. Detailed understanding the clinical characteristics and prognostic factors in nonsurgically treated P-ADC may allow the identification of patients with particular risk factors and initiation of early and specific treatment in order to optimize outcomes.
Pectoral nerve block in anesthesia for modified radical mastectomy
Authors: Zhao Jia , Han Fanglei , Yang Yang , Li Hangyu , Li Zinan 
Published: May 2019

Abstract

Background:
Many types of regional nerve blocks have been used during anesthesia for modified radical mastectomy. In recent years, the use of pectoral nerve (PECS) block has gained importance in postoperative analgesia, but there are still controversies regarding its efficacy. There is especially no consensus on the optimal type of PECS block to be used. Herein, we attempt to evaluate the analgesic efficacy of the PECS block after radical mastectomy.

Methods:
We searched PubMed, EMBASE, and the Cochrane library for randomized controlled trials (RCTs) for studies regarding PECS versus general anesthesia (GA) that were published prior to May 31, 2018. Outcome measures such as intra- and postoperative consumption of opioids, postoperative nausea and vomiting (PONV), need for postoperative rescue analgesia, and pain scores were analyzed. After quality evaluation and data extraction, a meta-analysis was performed using Review Manager 5.3 software, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used for rating the quality of evidence.

Results:
A total of 8 RCTs and 2 cohort studies involving 993 patients were eligible. Compared with the GA group, the PECS block group effectively reduced the intraoperative and postoperative use of opioid drugs, incidence of PONV, need for postoperative rescue analgesia, and pain scores within 0 to 6 hours after surgery. However, subgroup analysis showed that PECS I block did not have a significant advantage in reducing the intra- and postoperative consumption of opioids. Results for each outcome indicator were confirmed as having a high or moderate level of evidence.

Conclusions:
Even considering the limitations (evaluations of efficacy in different age groups and for chronic pain were not carried out) of this meta-analysis, it can be concluded that the PECS II block is an effective anesthetic regimen in modified radical mastectomy that can effectively reduce the intra- and postoperative consumption of opioids, postoperative PONV, and the need for postoperative rescue analgesia and can alleviate early pain (0–6 hours) after surgery.

Published: May 2019

Abstract

Introduction:
There are few studies focusing on Binocular hepatitis B related optic neuritis (HB-ON) and associated therapies are still limited. We present a case of HB-ON which has been cured with therapeutic plasma exchange (TPE).

Patient concerns:
The patient was diagnosed as acute hepatitis B in hepatology and got a rapid loss of binocular visual acuity (2/100 in the right eye and no light perception in the left eye) after the onset.

Diagnosis:
Hepatitis B related optic neuritis.

Interventions:
Methylprednisolone and therapeutic plasma exchange.

Outcomes:
The treatment of high dose methylprednisolone was not curative. After 5 TPE sessions, the patient's best corrected visual acuity (BCVA) returned to 20/20 in the right eye and finger counting (FC)/40 cm in the left eye. One month later, the visual acuity increased to 5/100 in the left eye.

Conclusion:
This is the first case in which we used TPE to cure HB-ON. Also, it can demonstrate the relationship between HB-ON and immunopathogenesis. The case may provide an effective method for the treatment of hormone invalid and disabled ON in clinical practice.

Abstract

TP53 gene is mutated in approximately 80% of triple-negative breast cancer (TNBC). However, the prognostic significance of immunohistochemical (IHC)-detected p53 protein expression remains controversial in TNBC. In this study, we retrospectively analyzed the association between IHC-detected p53 expression and the prognosis in a cohort of 278 patients with stage I-III triple-negative breast invasive ductal carcinoma (IDC), who received surgery at the department of breast surgery in the Fourth Hospital of Hebei Medical University from 2010–01 to 2012–12. We found a positive expression ratio of IHC-detected p53 in triple-negative breast IDC of 58.6% (163/278). Furthermore, levels of expression were significantly associated with vessel tumor emboli and higher histologic grade (P = .038, P = .043, respectively), with the highest expression level observed in G3 breast cancer (64.7%). Additionally, Kaplan-Meier analysis showed that p53 expression indicated worse overall survival (OS) in the whole cohort (79.6% vs 89.6%, Log-rank test P = .025) as well as in stratified prognostic stage II patients (90.8% vs 100%, Log-rank test P = .027). The mortality risk of p53 expression patients was 2.22 times higher than that of p53 negative patients (HR: 2.222; 95%CI: 1.147–4.308). In addition, p53 expression was also associated with poor disease-free survival (DFS) (76.7% vs 86.8%, P = .020). Cox proportional hazard ratio model showed p53 expression was an independent risk factor for OS (P = .018) and DFS (P = .018) after controlling for tumor size, lymph node status, and vessel tumor emboli. Altogether, our data showed that IHC-detected p53 expression is a promising prognostic candidate for poor survival in triple-negative breast IDC patients. However, more studies are needed to determine if p53 may be applied to clinical practice as a biomarker and/or novel therapeutic target for TNBC.
