Abstract
Background: Progesterone Receptor Membrane Component 1 (PGRMC1) is expressed in many cancer cells, where it is associated with detrimental patient outcomes. It contains phosphorylated tyrosines which evolutionarily preceded deuterostome gastrulation and tissue differentiation mechanisms. Results: We demonstrate that manipulating PGRMC1 phosphorylation status in MIA PaCa-2 (MP) cells imposes broad pleiotropic effects. Relative to parental cells over-expressing hemagglutinin-tagged wild-type (WT) PGRMC1-HA, cells expressing a PGRMC1-HA-S57A/S181A double mutant (DM) exhibited reduced levels of proteins involved in energy metabolism and mitochondrial function, and altered glucose metabolism suggesting modulation of the Warburg effect. This was associated with increased PI3K/Akt activity, altered cell shape, actin cytoskeleton, motility, and mitochondrial properties. An S57A/Y180F/S181A triple mutant (TM) indicated the involvement of Y180 in PI3K/Akt activation. Mutation of Y180F strongly attenuated subcutaneous xenograft tumor growth in NOD-SCID gamma mice. Elsewhere we demonstrate altered metabolism, mutation incidence, and epigenetic status in these cells. Conclusions: Altogether, these results indicate that mutational manipulation of PGRMC1 phosphorylation status exerts broad pleiotropic effects relevant to cancer and other cell biology.

Abstract
Objective: To explore the clinical efficacy of pararectus approach combined with 3D printing technique for the surgical treatment of partial acetabular fractures.Methods: We retrospectively evaluated 33 (20 males and 13 females) patients with acetabular fractures in the period of June 2017 to December 2018; According to judet-letenneal classification: 11 cases were of anterior column fracture, 10 cases were of double column fracture, 7 fractures were of the anterior column with posterior half transverse,3 fractures were of transverse fracture, and 2 case was of "T" fracture. For all cases, 3D printing is used to print the acetabular model. Pre-bent reconstruction plates from the model were placed to fixate fractures via the pararectus approach. Results : Thirty-three patients were followed up for 12-18 months (average,14 months); two patients (6.0%) developed postoperative ossifying myositis, and there are no obvious symptoms at present; One patient (3.0%) developed postoperative wound infection, and the wound completely improved by secretion culture, enhanced dressing and effective antibiotics; All the acetabular fractures united after 12 to 16 weeks(average,13 weeks);According to the modified Merle d’Aubigne and Postel scoring system to assess the hip function: excellent in 22 cases (66.7%), good in 7 cases(21.2%) and fair in 4 cases(12.1%).Conclusions: In the treatment of partial acetabular fractures, the pararectus approach combined with 3D printing technique can achieve effective reduction and fixation, decrease intraoperative hemorrhage, shorten operation time and the internal fixation position can be properly adjusted during the operation by looking directly at the model.

Abstract
Background Several previous studies reported a greater prevalence of dry eye syndrome (DES) among patients with psychiatric diseases. The aim of this study is to investigate the prevalence and risk factors of DES in patients with psychiatric disorders (PD) using nationwide population-based data in Taiwan. Methods This population-based cohort study retrospectively identified patients with PD from 1997 to 2011. Patients with both PD and DES served as the DES cohort, and PD patients without DES comprised the non-DES cohort. PD was defined as a diagnosis of PD (ICD-9-CM 290-319) made by psychiatrists only, with at least three consecutive outpatient visits or at least one inpatient visit. DES was defined as a diagnosis of DES (ICD-9-CM 375.15) and a prescription for an eye lubricant (anatomical therapeutic chemical code, ATC code: S01XA). The main outcome measures were the prevalence of DES in these patients and associated risk factors. Results A total of 75,650 patients with PD (3,665 in the DES cohort and 71,985 in the non-DES cohort) were included in the final analysis. The majority of patients in the DES group were women (72.6%), compared the non-DES group (57.8%). The mean age of patients in the DES cohort was 62.2 ± 14.9, which was significantly older than those in the non-DES group (50.9 ± 17.5). The patients with DES had a significantly greater likelihood of having dementia, bipolar disorder, depression, and neurotic disorders. Conditional regression analyses revealed that patients with dry eye disease were more likely to have schizophrenia (OR = 1.34), bipolar disorder (OR = 1.9), depression (OR = 1.54), and neurotic disorders (OR = 1.62). In addition, patients with DES were more likely to use 1st generation anti-psychotics (OR=1.28) and had a lower risk of using 2 nd generation anti-psychotics (OR=0.64) Conclusion The study demonstrated that among PD patients, DES is highly prevalence in certain subtypes of PD, such as depression, bipolar disorder, and neurotic disorders, after adjusting for the comorbidities.

Abstract
BackgroundPeople with serious mental illness (SMI) have sexual health needs but there is little evidence to inform effective interventions to address them. In fact, there are few studies that have addressed this topic for people with SMI outside USA and Brazil. Therefore, the aim of the study was to establish the acceptability and feasibility of a trial of a sexual health promotion intervention for people with SMI in the UK.MethodThe RESPECT study was a two-armed randomised controlled, open feasibility study comparing Sexual health promotion intervention (3 individual sessions of 1 hour) (I) or usual care (UC) for adults aged 18 or over, with SMI, within community mental health services in four UK cities. The main outcome of interest was the percentage who consented to participate, and retained in each arm of the trial, retention for the intervention, and completeness of data collection. A nested qualitative study obtained the views of participants regarding the acceptability of the study using individual telephone interviews conducted by lived experience researchers. ResultsOf a target sample of 100, a total of 72 people were enrolled in the trial over 12 months. Recruitment in the initial months was low and so an extension was granted. However this extension meant that the later recruited participants would only be followed up to the 3 month point. There was good retention in the intervention and the study as a whole; 77.8% of those allocated to intervention (n=28) received it. At three months, 81.9% (30 I; 29 UC) and at 6 months, 76.3% (13 I and 16 UC) completed the follow-up interviews. No adverse events were reported. There was good completeness of the data. The sexual health outcomes for the intervention group changed in favour of the intervention. Based on analysis of the qualitative interviews, the methods of recruitment, the quality of the participant information, the data collection, and the intervention were deemed to be acceptable to the participants (n=22). ConclusionsThe target of 100 participants was not achieved within the study’s timescale. However, effective strategies were identified that improved recruitment in the final few months. Retention rates and completeness of data in both groups indicate that it is acceptable and feasible to undertake a study promoting sexual health for people with SMI. A fully powered RCT is required to establish effectiveness of the intervention in adoption of safer sex.

Abstract
Background To address the possibility of safe cessation of nucleos(t)ide analogues (NAs) therapy in chronic hepatitis B (CHB) and to identify factors associated with off-NAs virological relapse (VR). Methods A published work search was performed to identify all published studies including patients who ceased NAs and were followed for ≥12 months. A meta-analysis was performed. Results Twenty-six studies involving 2573 patients who discontinued NAs were included. The pooled rate of off-NAs VR was 0.63, being lower in initially hepatitis B e antigen (HBeAg)-positive than HBeAg-negative patients (0.57 versus 0.62, P = 0.732). The pooled rates of VR were 0.47, 0.55, 0.61, 0.51, 0.73 and 0.64 at 6, 12, 24, 36, 48 and 60 months after NAs cessation, respectively, being relatively lower in initially HBeAg–positive (0.31, 0.45, 0.55, 0.44, 0.48, 0.52) than HBeAg-negative patients (0.50, 0.55, 0.69, 0.57, 0.53, 0.68) (P = 0.405). The pooled rate of biochemical relapse was 0.44, being lower in initially HBeAg-positive than HBeAg-negative patients (0.43 versus 0.48, P = 0.554). The pooled rates of hepatitis B surface antigen loss and seroconversion was 0.09 and 0.06, respectively. The pooled rates of VR at 12 months after NAs cessation were significant different between duration of on-NAs virological response ≤24 months and >24 months in all patients (0.55 versus 0.41, P = 0.011), initially HBeAg-positive patients (0.59 versus 0.41, P = 0.031), and initially HBeAg-negative patients (0.53 versus 0.37, P = 0.025). Conclusions Safe cessation of NAs therapy seems to be feasible in a substantial proportion of CHB patients. On-NAs virological response >24 months reduces the risk of off-NAs VR. Stopping NAs treatment may have an impact on long-term HBsAg decline and also HBsAg clearance.

Published: March 2020

Abstract
Background: We did this study to analyse the risks posed by manual diluted morphine solutions intended for intrathecal use. Dilution of morphine is needed to achieve low concentrations for intrathecal injection. Dilution poses the risk of dilution errors and bacterial contamination. The primary goal was to compare the concentrations of morphine and bupivacaine between four groups of syringes. The secondary goal was to investigate the difference in contamination rate between these groups. Methods: 25 experienced anaesthesia providers were asked to prepare a mixture of bupivacaine 2.0 mg/ml and morphine 60 µg/ml using 3 different methods as clean and precise as possible. The fourth method used was the aspiration of ampoules prepared by the pharmacy. The concentrations of morphine and bupivacaine were measured by High-Pressure Liquid Chromatography (HPLC). The medication was cultured for bacterial contamination. Results: Group 1 (60 µg/ml; 95% CI: 59-110 µg/ml) yielded 3 outliers above 180 µg/ml morphine concentration. Group 2 (76 µg/ml; 95% CI: 72-80 µg/ml) and 3 (69 µg/ml; 95% CI: 66-71 µg/ml) were consistently higher than the target concentration of 60 µg. The group “pharmacy” was precise and accurate (59 µg/ml; 95% CI: 59-59 µg/ml). Two groups had one contaminated sample with a spore-forming aerobic gram-positive rod. Conclusion: Manually diluted morphine is at risk for deviating concentrations, which could lead to increased side-effects. Medication produced by the hospital pharmacy was highly accurate. Furthermore, even when precautions are undertaken, contamination of the medication is a serious risk and appeared to be unrelated to the dilution process. Trial registration: Not applicable

Published: March 2020

Abstract
Background Multiple studies have suggested that various pesticides are associated with a higher risk of developing Parkinson’s disease (PD) and may influence the progression of the disease. This study examines whether pesticide exposure influences the risk of mortality among patients with PD in Southern Brazil, when accounting for socioeconomic status, nicotine exposure, and caffeine exposure. Methods 150 patients with idiopathic PD were enrolled from 2008-2013 and followed until 2019. In addition to undergoing a detailed neurologic evaluation, patients completed surveys regarding socioeconomic status and environmental exposures. Results Twenty patients (13.3%) reported a history of occupational pesticide exposure with a median duration of exposure of 10 years (mean = 13.1, SD = 11.2). Patients with a history of occupational pesticide exposure had higher UPDRS-III scores, though there were no significant differences in regards to age, sex, disease duration, Charlson Comorbidity Index, and age at symptom onset. Patients with occupational pesticide exposure were more than twice as likely to die than their unexposed PD counterparts (HR = 2.32, 95% CI [1.15, 4.66], p = 0.22). Occupational pesticide exposure was also a significant predictor of death in a cox-proportional hazards model which included smoking and caffeine intake history and another which included several measures of socioeconomic status. Conclusion In this prospective cohort study, we found an increased all-cause mortality risk in PD patients with occupational exposure to pesticides. More studies are needed to further analyze this topic with longer follow-up periods, more detailed exposure information, and more specific causes of mortality.

Abstract
Background : With the increasing worldwide prevalence and disease burden of diabetic mellitus, data on the impact of diabetes on acute kidney injury (AKI) patients in China are limited.Methods: A nationwide cross-sectional and retrospective study was conducted in China, which included 2,223,230 hospitalized adult patients and covered 82% of the country’s population. Diabetes was identified according to blood glucose, hemoglobin A1c levels, physician diagnosis and drug use. In total, 7604 AKI patients were identified, and 1404 and 6200 cases were defined as diabetic and non-diabetic respectively. Clinical characteristics, outcome, in-hospital stay, and costs of AKI patients with and without diabetes were compared. Multivariable logistic and linear regression analyses were conducted to evaluate the association of diabetes with mortality and renal recovery in the admitted AKI patients.Results: In this survey, AKI patients with diabetes were older, male-dominated (61.9%), with more comorbidities, and higher serum creatinine levels. Compared to patients without diabetes, a significant upswing in all-cause in-hospital mortality, hospital stay, and costs were found in those with diabetes ( p <0.05). After adjusted for relevant covariables, diabetes was independently associated with failed renal recovery (OR=1.13, p =0.04), rather than all-cause in-hospital mortality (OR=1.09, p =0.39). Also, diabetic status was positively associated with length of stay ( β =0.04, p =0.04) and costs ( β =0.09, p <0.01) in hospital after adjusted for possible confounders. Conclusions: Failed renal recovery, rather than all-cause in-hospital mortality, is independently associated with diabetes in hospitalized AKI patients. Moreover, diabetes is significantly correlated with in-hospital stay and expenditures in AKI.

Published: March 2020

Abstract
Background Nitrogen (N) and phosphorus (P) control in sediment remediation through adding natural material has been paid more and more attention. In this study, different natural material including iron-rich clay mineral, calcite, kaoline, sugarcane bagasse and Phragmites detritus was applied to test the effect on N and P control in a mesocosm experiment. Results Iron-rich clay mineral and Phragmites detritus had an obvious advantage on P control in terms of almost undetectable soluble reactive phosphorus (SRP) in water column throughout the experiment, which could be explained by strong P adsorption ability. The high available organic carbon in sediment and water column after sugarcane bagasse addition provided enough electron donors for denitrification and dissimilatory nitrate reduction to ammonium (DNRA), which was responsible for nitrate (NO 3 - -N) deficiency and ammonium (NH 4 + -N) accumulation in water column. Also this resulted in anaerobic status, further fuelling P release from iron-bound P induced by anoxia. Thus, sugarcane bagasse application should be considered its dosage in order to balance the denitrification and DNRA as well as P release. Calcite and Phragmites detritus should be recommended as remediation material for N removal according to the significant promotion of denitrification and limitation of DNRA, finally resulting in low NO 3 - -N and NH 4 + -N. These results could be explained by the shift of functional microbial community composition and abundance after natural material addition. Conclusions Iron-rich clay mineral and Phragmites detritus should be regarded as the promising sediment remediation material for P immobilization due to the increase of P adsorption ability. Taken together, the selection of sediment remediation material should combine the N and P coupling relationship, avoiding that NO 3 - -N removal caused the P leaching or NH 4 + -N accumulation.

Abstract
Background Total hip and total knee arthroplasties are among the most common types of surgery performed in Australia today and are effective treatments for severe osteoarthritis. However, the increasing financial burden on the health system owing to the increasing rates of surgery has led to a growing interest in improving the cost-effectiveness and safety of arthroplasty care. This study was designed to examine the association between post-operative complications, a major cost driver, and the cost of investigations following total hip or knee arthroplasty. Methods This is a prospective cohort study of consecutive patients undergoing primary total hip or knee arthroplasty at an Australian public hospital. We measured the number and cost of imaging and pathology tests performed during the acute hospital stay and used linear regression to examine the association between complication status and investigations costs. Results 500 patients were included in the analysis. On average, those with complications received more tests, and more expensive tests. The mean combined cost of imaging and pathology tests in patients with no complications was AU$ 187 (SD: 12.0). In comparison, patients with minor complications had a mean additional cost of AU$ 270 (SD: 31.0), and those with major complications had a mean additional cost of AU$ 493 (SD: 54.2) (p<0.001). Conclusions In patients undergoing hip or knee arthroplasty, investigation costs are substantially greater in the presence of either minor or major complications. With growing volumes of total hip and total hip arthroplasties, a potential focus of future research could include optimising investigation practices for patients with and without complications.
Barriers to accessing health-care services: A qualitative study of migrant construction workers in a Southwestern Indian city
Authors: Santalahti Maija , Sumit Kumar , Perkiö Mikko 
Published: March 2020

Abstract
Background: This study examined access to health care in an occupational context in an urban city of India. Many people migrate from rural areas to cities, often across Indian states, for employment prospects. The purpose of the study is to explore the barriers to accessing health care among a vulnerable group – internal migrants working in the construction sector in Manipal, Karnataka. Understanding the lay workers’ accounts of access to health service can help to comprehend the diversity of factors that hinder access to health care. Methods: Individual semi-structured interviews involving 15 migrant construction workers were conducted. The study applied theory-guided content analysis to investigate access to health services among the construction workers. The adductive analysis combined deductive and inductive approaches with the aim of verifying the existing barrier theory in a vulnerable context and further developing the health-care access barrier theory. Results: This study’s result is a revised version of the health-care access barriers model, including the dimension of trust. Three known health-care access barriers – financial, cognitive and structural, as well as the new barrier (distrust in public health-care services), were identified among migrant construction workers in a city context in Karnataka, India.Conclusions: Further qualitative research on vulnerable groups would produce a more comprehensive account of access to health care. The socioeconomic status behind access to health care, as well as distrust in public health services, forms focal challenges for any policymaker hoping to improve health services to match people’s needs.
