services from multiple providers. Little is known about how patients with chronic fatigue syndrome/myalgic
encephalomyelitis (CFS/ME) experience continuity of GP care.
This study explores how women with CFS/ME experience GP care across the three dimensions of continuity:
informational, management, and relational continuity.
Methods: This cross-sectional study uses questionnaire data collected from members of The Norwegian ME
Association. Descriptive statistics and logistic regressions were used to estimate experiences of continuity, and
associations with age, education, self-rated degree of CFS/ME, duration of the GP relation (GP duration), and
number of GP visits for CFS/ME-related issues during the previous year (GP frequency).
Results: Almost two-thirds of participants reported positive experiences across all three dimensions of GP
continuity of care; 64.4% for informational, 64.1% for management, and 77.2% for relational continuity. Lower
educational attainment was associated with more negative experiences of informational continuity (primary school
only compared to university educated: odds ratio [OR] 0.12, confidence interval [CI] 0.03â0.49, p = 0.003). Compared
to participants aged 40â59 years, those aged 60+ years were significantly less likely to have experienced poor
(negative) management continuity (OR 0.25, CI 0.09â0.76, p = 0.014). A GP relationship of three or more years was
associated with positive experiences of relational continuity (OR 2.32, CI 1.09â4.95, p = 0.030). Compared to those
with moderate CFS/ME, those who graded their CFS/ME as severe or very severe were significantly more likely to
have negative experiences of relational continuity (OR 0.38, CI 0.14â0.99, p = 0.047).
Conclusions: A large proportion of participants experienced all three aspects of continuity of GP care (especially
the relational dimension) positively. Informational and management continuity scores were moderately lower. Our
results suggest greater emphasis on information giving, feedback, and better coordination of care to be good
strategies for practice improvement for this patient group

Accurate determination of the atmospheric abundance of hydrogen bound bimolecular complexes is necessary, as hydrogen bonds are partly responsible for the formation and growth of aerosol particles.
The abundance of a complex is related to the Gibbs free energy of complex formation (), which is often obtained from quantum chemical calculations that rely on calculated values of the enthalpy () and entropy () of complex formation.
However, calculations of and in particular are associated with large uncertainties, and accurate experimental values are therefore crucial for theoretical benchmarking studies.
Infrared measurements of gas phase hydrogen bound complexes were performed in the 300 to 373 K range, and lead to a purely experimental determination of using the van't Hoff equation.
Equilibrium constants were determined by combining an experimental and calculated OH-stretching intensity, from which values of and hence could be determined.
Thus we can determine , and for a bimolecular complex.
We find that in the 300 to 373 K temperature range the determined and values are independent of temperature
Responses and relationship dynamics of men and their spouses during active surveillance for prostate cancer: health literacy as an inquiry framework
BACKGROUND: Early stage prostate cancer patients may be allocated to active surveillance, where the condition is observed over time with no intervention. Living with a cancer diagnosis may impose stress on both the men and their spouses. In this study we explore whether the scores of and verbal responses to a Health Literacy Questionnaire can be used to identify individuals in need of information and support and to reveal differences in perception and understanding in health related situations within couples. METHODS: We used the nine-domain Health Literacy Questionnaire (HLQ) as a framework to explore health literacy in eight couples where the men were on active surveillance for prostate cancer progression. Scores were calculated for each domain for both individuals. For each couple differences in scores were also calculated and related to the informants\u27 self-reported experiences and reflections in relation to participating in an active surveillance program. Also an inductive analysis was performed to identify themes in the responses and these themes were compared to those of HLQ. RESULTS: The men tended to score higher than their spouses. There was no consistent relation between scores and the reported experiences and reflections. However, some interesting patterns emerged, e.g. in two of the three couples with the largest within couple differences in HLQ scores, responses revealed discrepancies in how the men and their spouses perceived their situation. Also, three themes emerged which related to six of the HLQ domains, i.e. involvement of spouses and other people around the men; support from and interaction with healthcare professionals; and use of the Internet for information retrieval. CONCLUSIONS: Using the HLQ as an interview framework provided insight into the differences within couples and provided new perspectives on their experiences, including their contact with health professionals and the patient-spouse interaction when dealing with prostate cancer. The HLQ used as a dialogue tool may be an adjunct to assist healthcare providers to understand the need for support and information of men with prostate cancer on active surveillance and the dynamics within couples
Current strategies for mobilome research
Mobile genetic elements (MGE) are pivotal for bacterial evolution and adaptation, allowing shuffling of genes even between distantly related bacterial species. The study of MGEs is biologically interesting as the mode of genetic propagation is kaleidoscopic and important, as MGEs are the main vehicles of the increasing bacterial antibiotic resistance that causes thousands of human deaths each year. The study of MGEs has previously focused on plasmids from individual isolates, but the revolution in sequencing technology has allowed the study of mobile genomic elements of entire communities using metagenomic approaches. The problem in using metagenomic sequencing for the study of MGEs is that plasmids and other mobile elements only comprise a small fraction of the total genetic content that are difficult to separate from chromosomal DNA based on sequence alone. Several different approaches have been proposed that specifically enrich plasmid DNA from community samples. Here, we review recent approaches used to study entire plasmid pools from complex environments, and point out possible future developments for and pitfalls of these approaches. Further, we discuss the use of the PacBio long-read sequencing technology for MGE discovery
Continuity of GP care is associated with lower use of complementary and alternative medical providers: a population-based cross-sectional survey
BACKGROUND: Continuity of general practitioner (GP) care is associated with reduced use of emergency departments, hospitalisation, and outpatient specialist services. Evidence about the relationship between continuity and use of complementary and alternative medical (CAM) providers has so far been lacking. The aim of this study was to test the association between continuity of GP care and the use of CAM providers. METHODS: We used questionnaire data from the sixth Tromsø Study, conducted in 2007â8. Using descriptive statistical methods, we estimated the proportion using a CAM provider among adults (30â87 years) who had visited a GP during the last 12 months. By means of logistic regressions, we studied the association between the duration of the GP-patient relationship and the use of CAM providers. Analyses were adjusted for the frequency of GP visits, gender, age, marital status, income, education, and self-rated health and other proxies for health care needs. RESULTS: Of 9,743 eligible GP users, 85.1% had seen the same GP for more than two years, 83.7% among women and 86.9% among men. The probability of visiting a CAM provider was lower among those with a GP relationship of more than 2 years compared to those with a shorter GP relationship (odds ratio [OR] 0.81, 95% confidence interval [CI] 0.68-0.96). Other factors associated with CAM use were female gender, poor health, low age and high income. There was no association with education. CONCLUSIONS: Continuity of GP care as measured by the duration of the GP-patient relationship was associated with lower use of CAM providers. Together with previous studies this suggests that continuity of GP care may contribute to health care delivery from fewer providers
The Nordic maintenance care program: what are the indications for maintenance care in patients with low back pain? A survey of the members of the Danish Chiropractors' Association
<p>Abstract</p> <p>Background</p> <p>Maintenance care (MC) is relatively commonly used among chiropractors. However, factual information is needed on its indications for use.</p> <p>Objectives</p> <p>This study had two objectives: 1) to describe which role patients' past history and treatment outcome play in chiropractors' decision to use MC in patients with low back pain, 2) to investigate if the chiropractors' clinical/educational background has an effect on the frequency of using MC and their indications for use of MC.</p> <p>Method</p> <p>An anonymous questionnaire was sent to all 413 chiropractors practising in Denmark. Its main part consisted of 3 sets of 4 questions relating to one basic case of low back pain. For each case, the chiropractors were asked if they would use MC as they self-defined the term (no/perhaps/yes). There were questions also on gender, age, educational and clinical background, and on the number of MC patients seen by these chiropractors. Their decision to recommend MC was reported. Associations between the demographic variables and 1) the frequency of MC-use and 2) their indications for use of MC were tested through multivariate analysis.</p> <p>Results</p> <p>The response rate was 72%. Non-indications for MC were: 1) a good outcome combined with no previous events, or 2) a past history of LBP and gradual worsening with treatment. Indications for MC were a good outcome combined with a previous history of low back pain between once a month and once a year. The mean proportion of MC patients per week were 22% (SD 19), ranging from 0% to 100%. The use of MC was highest among experienced chiropractors, those who were educated in North America, and clinic owners. However, in Denmark most chiropractors graduated before 1999, are educated abroad, whereas most chiropractors thereafter are educated in Denmark. Therefore, we cannot conclude whether this difference relates to education or years of experience. There were no associations detected between demographic variables and the indications for MC.</p> <p>Conclusions</p> <p>There is relatively high consensus on when MC should and should not be used. A history of prior low back pain combined with a positive response to treatment encourages the use of MC, whereas no previous history of back pain or a worsening of symptoms discourages the use of MC. There seems to be a difference in the proportional use of MC between chiropractors with more experience educated in North America and those with less experience educated in Denmark.</p
In vivo detection of cortical optical changes associated with seizure activity with optical coherence tomography.
The most common technology for seizure detection is with electroencephalography (EEG), which has low spatial resolution and minimal depth discrimination. Optical techniques using near-infrared (NIR) light have been used to improve upon EEG technology and previous research has suggested that optical changes, specifically changes in near-infrared optical scattering, may precede EEG seizure onset in in vivo models. Optical coherence tomography (OCT) is a high resolution, minimally invasive imaging technique, which can produce depth resolved cross-sectional images. In this study, OCT was used to detect changes in optical properties of cortical tissue in vivo in mice before and during the induction of generalized seizure activity. We demonstrated that a significant decrease (P < 0.001) in backscattered intensity during seizure progression can be detected before the onset of observable manifestations of generalized (stage-5) seizures. These results indicate the feasibility of minimally-invasive optical detection of seizures with OCT

Coulomb Breakup Mechanism of Neutron-Halo Nuclei in a Time-Dependent Method
The mechanism of the Coulomb breakup reactions of the nuclei with
neutron-halo structure is investigated in detail. A time-dependent
Schr\"odinger equation for the halo neutron is numerically solved by treating
the Coulomb field of a target as an external field. The momentum distribution
and the post-acceleration effect of the final fragments are discussed in a
fully quantum mechanical way to clarify the limitation of the intuitive picture
based on the classical mechanics. The theory is applied to the Coulomb breakup
reaction of Be + Pb. The breakup mechanism is found to be
different between the channels of and
, reflecting the underlying structure of Be. The
calculated result reproduces the energy spectrum of the breakup fragments
reasonably well, but explains only about a half of the observed longitudinal
momentum difference.Comment: 15 pages,revtex, 9 figures (available upon request
