Self‐reported financial burden of cancer care and its effect on physical and mental health‐related quality of life among US cancer survivors
Authors: Kale Hrishikesh P. , Carroll Norman V. 
Published: March 2016

BACKGROUNDCancer‐related financial burden has been linked to cancer survivors (CS) forgoing/delaying medical care, skipping follow‐up visits, and discontinuing medications. To the authors' knowledge, little is known regarding the effect of financial burden on the health‐related quality of life of CS.METHODSThe authors analyzed 2011 Medical Expenditure Panel Survey data. Financial burden was present if one of the following problems was reported: borrowed money/declared bankruptcy, worried about paying large medical bills, unable to cover the cost of medical care visits, or other financial sacrifices. The following outcomes were evaluated: Physical Component Score (PCS) and Mental Component Score (MCS) of the 12‐Item Short‐Form Health Survey (SF‐12), depressed mood, psychological distress, and worry related to cancer recurrence. The authors also assessed the effect of the number of financial problems on these outcomes.RESULTSOf the 19.6 million CS analyzed, 28.7% reported financial burden. Among them, the average PCS (42.3 vs 44.9) and MCS (48.1 vs 52.1) were lower for those with financial burden versus those without. In adjusted analyses, CS with financial burden had significantly lower PCS (β = ‐2.45), and MCS (β = ‐3.05), had increased odds of depressed mood (odds ratio, 1.95), and were more likely to worry about cancer recurrence (odds ratio, 3.54). Survivors reporting ≥ 3 financial problems reported statistically significant and clinically meaningful differences (≥3 points) in the mean PCS and MCS compared with survivors without financial problems.CONCLUSIONSCancer‐related financial burden was associated with lower health‐related quality of life, increased risk of depressed mood, and a higher frequency of worrying about cancer recurrence among CS.

The Experience of Postnatal Depression in Immigrant Mothers Living in Western Countries: A Meta‐Synthesis
Authors: Wittkowski Anja , Patel Sonia , Fox John R. 
Published: March 2016

BackgroundPostnatal depression affects women from all cultures and countries. The postnatal period is thought to be a vulnerable time for all mothers. Immigrant women may be at particular risk as they attempt to adhere to childbirth rituals in western societies which might exacerbate stress, while navigating through the multiple stressors they face from migration in the transition to motherhood.MethodsThis study utilized a meta‐synthesis approach to synthesize qualitative studies exploring postnatal depression in immigrant mothers living in western countries. Searching six databases identified 16 studies that met criteria.ResultsThe synthesis revealed two overarching themes of migration and cultural influences on immigrant mothers that interact and give rise to psychosocial understandings of postnatal depression, remedies and healthcare barriers. Mothers used self‐help coping strategies in line with this.ConclusionsImmigrant mothers living in western countries are subject to multifactorial stressors following childbirth, increasing their susceptibility to postnatal depression. These stressors relate to being an immigrant in a western society and cultural influences, which may be harder to comply with, when removed from their sociocultural context. Social support appears to play a mediating role for these immigrant mothers. There were several similarities between immigrant and non‐immigrant mothers including their views of healthcare and medication, their health‐seeking behaviours and their fears of having their baby removed. All these findings have implications for healthcare settings in terms of assessments and service delivery. Copyright © 2016 John Wiley & Sons, Ltd.Key Practitioner Message

In this meta‐synthesis, we explored the experience of postnatal depression in immigrant women living in western countries, including the UK, the USA and Canada.
Sixteen qualitative studies were reviewed, and their methodological quality was examined.
The findings are based a total sample of 337 women.
Two overarching themes were identified that are termed ‘cultural influences’ and ‘migration factors’, which influenced how these mothers coped with their postnatal depression.
Social support played a mediating role for these immigrant mothers.
Genesis and tectonic implications of cumulate pyroxenites and tectonite peridotites from the Nagaland–Manipur ophiolites, Northeast India: constraints from mineralogical and geochemical characteristics

AbstractThe Nagaland–Manipur ophiolites (NMO) of Northeast India forms a part of the Tethyan ophiolites and comprises a suite of tectonite peridotites and cumulate mafic–ultramafic sequence with mafic extrusive–intrusive rocks, felsic intrusives and oceanic pelagic sediments along with minor podiform chromitites. However, sheeted dykes, which are considered as a significant component of ophiolites, are absent in the NMO. The tectonite peridotites are distinguished from the cumulate pyroxenites by the presence of pyroxene lineation, deformed bands and strained extinction in olivine, kink twin lamellae in pyroxene. Both the tectonite peridotites and cumulate pyroxenites contain aluminous spinel with Cr number [Cr# = Cr/(Cr + Al)] in the range of 0.14 to 0.29 and 0.27 to 0.48, respectively. Mg number [Mg# = Mg/(Mg + Fe2+)] in Cr‐spinel is higher in tectonite peridotites (0.71–0.76) than cumulate pyroxenites (0.44–0.53). Chondrite‐normalized rare earth elements (REE) patterns of cumulate pyroxenites exhibit depleted at light REEE (LREE) (LaN/SmN = 0.380–0.759) but flat middle REE (MREE) to heavy REE (HREE) (SmN/YbN = 0.622–0.756). However, the tectonite peridotites show gradual decrease in concentrations from HREE to MREE (SmN/YbN = 0.285–0.460) and slight increase in LREE (LaN/SmN = 0.721–2.201). The cumulate pyroxenites show strong enriched PPGE patterns and higher PGE concentrations (∑PGE = 85.8–163.5 ppb) compared with the tectonite peridotites (∑PGE = 34.8–113.0 ppb). The estimated equilibration temperature ranges from 890 to 931 °C for cumulate pyroxenites and 971 to 1156 °C for tectonite peridotites. The olivine–spinel equilibrium along with Cr‐spinel chemistry and PGE data suggests that the tectonite peridotites represent the residual mantle left after limited extraction of basaltic melts by low‐degree partial melting (<15%). Conversely, the presence of highly magnesian orthopyroxene and clinopyroxene in the cumulate pyroxenites in conjunction with their geothermometry suggests that they were formed at high pressure and temperature by magmatic fractionation from the basaltic melt. The geochemical data together with field and petrographical evidences indicate that both the tectonite peridotites and cumulate pyroxenites are essentially spinel‐bearing and devoid of plagioclase, suggesting their derivation in the mantle beyond the stability limit of plagioclase in a mid‐oceanic ridge tectonic setting. We conclude that the ultramafic sequence of the NMO was initially generated at a mid‐oceanic ridge tectonic setting close to the eastern boundary of the Indian passive margin and then thrust over the continental margin of the Indian Plate towards the west during its collisional and subduction process with/beneath the Myanmar Plate.

Published: March 2016

ObjectiveThis study aimed to investigate whether sitting time, as a form of sedentary behaviour, is related to incident depressive symptoms in older people.MethodsThis study included 3503 participants (mean age 71.7 years, 50.1% female) from the ‘Obu Study of Health Promotion for the Elderly' cohort study. At baseline and then 15 months later, the participants reported their status of depressive symptoms using the 15‐item Geriatric Depression Scale. During the baseline assessment, the participants were also asked about their sedentary behaviour on weekdays over the past 7 days and, from there, categorized into three groups (<240, 240–480, ≥480 min/day). Demographic data and the other health behaviours were also assessed at the baseline.ResultsCross‐sectional analysis revealed that 437 participants (12.0%) had depressive symptoms. In a prospective analysis, the logistic regression model revealed that the odds ratio for depressive symptom incidence was higher in participants who, at baseline, spent 480 min or more per day sitting (1.636; 95% confidence interval [CI] 1.015 to 2.636, p = 0.043), and in those who spent 240–480 min (1.605; 95% CI 1.085 to 2.375, p = 0.018) in comparison with those who spent less than 240 min.ConclusionsSedentary behaviour significantly affects the risk of incident depressive symptoms. Further research is needed to develop an intervention strategy to manage depressive symptoms, as the second most common cause of burden of disease among older adults.

Published: March 2016

BackgroundChlamydia trachomatis causes the most common bacterial sexually transmitted infection (STI) worldwide. Although highly sensitive nucleic acid amplification tests (NAATs) are used to routinely diagnose chlamydial infection, C. trachomatis isolation by cell culture is still preferred for legal cases and epidemiological studies because of its high specificity; however, the sensitivity of traditional two‐passage diagnostic cultures is significantly lower than that of NAATs. Therefore, we sought to analyze if additional in vitro passaging of clinical samples would improve detection sensitivity of C. trachomatis.MethodsClinical swabs (n = 428) were collected from Tianjin Medical University General Hospital, grown in McCoy cells for up to five passages, and analyzed for the presence of inclusions by iodine staining. Results were confirmed by routine PCR‐based methods.ResultsViable C. trachomatis organisms were detected in 91 (21.26%) swabs with the traditional two‐passage protocol, which increased to 145 (33.88%) and 149 (34.81%) following three and four passages, respectively. Thus, the standard protocol yielded a false‐negative rate of nearly 39%. Subsequent PCR‐based diagnostics revealed a concordance rate of 80.98% between these two methods without any false negatives.ConclusionThe results of this study support the use of a three‐passage Chlamydia culture procedure to increase the detection sensitivity of this method.

AbstractInspired from butterfly wings that exhibit unique dewetting properties and brilliant structural color synchronously, we reported here the preparation of biomimetic few‐layer graphene films through a template‐directed chemical vapor deposition method using laser‐structured Cu foil as substrates. Hierarchical micronanostructures, including microscale stripes derived from the laser scanning and nanoscale laser‐induced periodic surface structures (LIPSS), formed on Cu foil after a simple femtosecond laser treatment. By tuning the laser power, the surface roughness of the resultant Cu foils can be well controlled. Using the laser structures Cu foil as templates, biomimetic few‐layer graphene films with both iridescence and superhydrophobicity have been successfully prepared. The present work may open up a new way to design and prepare structured graphene film in a biomimetic manner, and we deem that the bioinspired few‐layer graphene films may find broad applications in the near future.

Thermoresponsive Poly(Ionic Liquid)s in Aqueous Salt Solutions: Salting‐Out Effect on Their Phase Behavior and Water Absorption/Desorption Properties
Authors: Okafuji Akiyoshi , Kohno Yuki , Ohno Hiroyuki 
Published: March 2016

Here, a thermoresponsive phase behavior of polymerized ionic liquids (PILs) composed of poly([tri‐n‐alkyl(vinylbenzyl)phosphonium]chloride) (poly([PnnnVB]Cl) is reported, where n (the number of carbon atoms of an alkyl chain) = 4, 5, or 6 after mixing with aqueous sodium chloride solutions. Both monomeric [P555VB]Cl and the resulting poly([P555VB]Cl) linear homopolymer show a lower critical solution temperature (LCST)‐type phase behavior in aq. NaCl solutions. The phase transition temperature of the PIL shifts to lower value by increasing concentration of NaCl. Also the swelling degree of cross‐linked poly([P555VB]Cl) gel decreases by increasing NaCl concentration, clearly suggesting the “salting‐out” effect of NaCl results in a significant dehydration of the poly([P555VB]Cl) gel. The absorbed water in the PIL gel is desorbed by moderate heating via the LCST behavior, and the absolute absorption/desorption amount is improved by copolymerization of [P555VB]Cl with more hydrophilic [P444VB]Cl monomer.

Poly(1‐Vinyl‐1,2,4‐triazolium) Poly(Ionic Liquid)s: Synthesis and the Unique Behavior in Loading Metal Ions
Authors: Zhang Weiyi , Yuan Jiayin 
Published: March 2016

Herein, the synthesis of a series of poly(4‐alkyl‐1‐vinyl‐1,2,4‐triazolium) poly(ionic liquid)s is reported either via straightforward free radical polymerization of their corresponding ionic liquid monomers or via anion metathesis of the polymer precursors bearing halide as counter anion. The ionic liquid monomers are first prepared via N‐alkylation reaction of commercially available 1‐vinyl‐1,2,4‐triazole with alkyl iodides, followed by anion metathesis with targeted fluorinated anions. The thermal properties and solubilities of these poly(ionic liquid)s have been systematically investigated. Interestingly, it is found that the poly(4‐ethyl‐1‐vinyl‐1,2,4‐triazolium) poly(ionic liquid) exhibited an improved loading capacity of transition metal ions in comparison with its imidazolium counterpart.
