Multiple prior concussions are associated with symptoms in high school athletes
Objectives: The purpose of this study was to evaluate the association of prior concussion on baseline computerized neurocognitive testing in a large cohort of high school athletes. Methods: This is a retrospective cohort study of student athletes from 49 Maine High Schools in 2010 who underwent baseline computerized neurocognitive evaluation with Immediate Post-Concussion Assessment and Cognitive Testing (ImPACTÂź). As part of the ImPACTÂź, subjects reported a prior history of concussion as well as demographic information and a symptom questionnaire. We used linear regression to evaluate the association of prior concussion with baseline: (1) ImPACTÂź composite scores; and (2) symptom scores. Results: Six thousand seventy-five subjects were included in the study, of whom 57% were boys. The majority of student athletes (85.3%) reported no prior history of concussion while 4.6% reported having sustained two or more prior concussions. On simple linear regression, increasing number of concussions was related to worse performance in verbal memory (P = 0.039) and greater symptoms scores (P < 0.001). On multivariate modeling, only the association with baseline symptoms remained (P < 0.001). Other factors associated with baseline symptom reporting in the multivariate model included mental health history, headache/migraine history, gender, developmental and/or learning problems, and number of prior concussions. Interpretation In this large-scale, retrospective survey study, history of multiple prior concussions was associated with higher symptom burden but not baseline computerized neurocognitive testing. The association between baseline symptom reporting and clinical and demographic factors was greater than the association with a history of multiple concussions
The Patient Centered Assessment Method (PCAM): integrating the social dimensions of health into primary care
Background: Social dimensions of health are known to contribute to what is often termed âpatient complex-ity,â which is particularly common among patients with multimorbidity. Health-care professionals require tools to help them identify and manage these aspects of patient needs. Objectives: To examine: (i) the Patient Centered Assessment Method (PCAM), a tool for assessing patient complexity in ways that are sensitive to the biopsychosocial dimensions of health, in primary care settings in Scotland; (ii) the impact of the PCAM on referral patterns and its perceived value; and (iii) the PCAMâs perceived applicability for use in a complex patient population. Design: Two studies are described: (i) a mixed-methods prospective cohort study of the implementation of the PCAM in primary care clinics; and (ii) a qualitative exploratory study that evaluated the value of the PCAM in a complex patient population. Results: Use of the PCAM did not impact patient satisfaction or perception of practitionersâ empathy, but it did increase both the number of onward referrals per referred patient (9â12%) and the proportion of referrals to non-medical services addressing psychological, social, and lifestyle needs. Nurses valued the PCAM, particularly its ability to help them address psychological and social domains of patientsâ lives, and found it to be highly relevant for use in populations with known high complexity. Conclusions: The PCAM represents a feasible approach for assessing patient needs with consider-ation to the social dimensions of health, and allows practitioners to refer patients to a broader range of services to address patient complexity
Hyperamylasemia post living donor nephrectomy does not relate to pain
Introduction
The aetiology of pain after laparoscopic donor nephrectomy remains unclear. Given the
proximity of the left kidney to the tail of the pancreas, we aimed to assess whether mobilisation
and retrieval of the left kidney might inflame the pancreas, leading to pain and
hyperamylasaemia in the post-operative period.
Patient and methods
In the present study, 16 consecutive live kidney donors were analysed in the same three months
period. Amylase levels were measured on days 1 and 2. For each 24-hour period postoperatively
analgesia consumption was recorded, as well as pain scores at rest on a visual
analogue scale (VAS).
Results
Three out of 16 donors presented hyperamylasemia. A multiple regression analysis found
levobupivacaine dose, propofol dose, transversus abdominis plane block and day 1 amylase did
not significantly predict pain scores. Interestingly, body mass index significantly correlated
with increased pain scores (p = 0.041). Also, increasing CO2 insufflation pressure and use of
local anaesthetic infusion catheters predicted a decreased deep pain score (p = 0.036 and p =
0.037).
Conclusion
There was no correlation of amylase levels and pain scores. Pancreatitis is a rare complication
of nephrectomy and no overt cases were seen in the case of donor nephrectomy
The Patient Centred Assessment Method for improving nurse-led biopsychosocial assessment of patients with long-term conditions: a feasibility RCT
BackgroundAnnual reviews of people living with long-term conditions (LTCs) are mostly conducted by practice nurses (PNs), who focus on the physical needs of patients. The broader mental well-being and social needs of patients are also important if they are to live well. The Patient Centred Assessment Method (PCAM) is a new tool to help PNs conduct biopsychosocial assessments of patientsâ needs.Research questionsIs it feasible and acceptable to use the PCAM in primary care nurse-led reviews for those with LTCs? Is it feasible and acceptable to run a cluster randomised trial of the PCAM in primary care?MethodsFour practitioner and two patient focus groups explored the acceptability and implementation requirements of the PCAM, which was then tested in a feasibility cluster randomised controlled trial aiming to recruit eight general practitioner (GP) practices and 16 nurses. Baseline data collection was conducted with nurses prior to randomisation, with a cohort of 10 patients per nurse, including patient demographics, patient evaluation of consultation, patient-completed outcomes (measured via the Consultation and Relational Empathy, Patient Enablement Instrument, WarwickâEdinburgh Mental Well-Being Scale, General Health Questionnaire and the Short Form questionnaire-12 items) and nurse referrals/signposting to services. Patient follow-up questionnaires were completed at 8 weeks. Practices were then randomised to the PCAM intervention or care as usual (CAU). Data collection was repeated for a second cohort of patients. Fidelity was tested by comparing a sample of recorded consultations before and after PCAM training. Qualitative interviews were conducted with PCAM nurses and a sample of patients.ResultsApproaches to 159 eligible practices resulted in the recruitment of six practices (10 nurses), with five practices (seven nurses) completing both data collection phases. Nurses collected baseline data on 113 patients, 71 of whom (62.8%) completed follow-up questionnaires. Five practices were randomised: three practices (six nurses) to the PCAM arm and two practices (four nurses) to the CAU arm. In phase 2, seven nurses collected data on 77 patients, of whom 40 (52%) completed follow-up. Only four PCAM nurses agreed to recording consultations, with five pre- and four post-PCAM recordings obtained. Post PCAM training, there was evidence of more attention being given to patientsâ mental well-being and social issues. The PCAM was fairly easily integrated into consultation, although some nurses reflected that this benefited from early support. Patients were not always aware of its use, but most were happy to have their needs assessed.LimitationsRecruitment of GP practices, and nurse recruitment and retention.ConclusionsThe PCAM is feasible and acceptable for use by primary care nurses and may have potential for encouraging biopsychosocial assessment of patients. Efforts required to recruit and retain staff indicate that a full trial is not feasible or cost-effective at this time.Future workThe PCAM intervention warrants further exploration as an effective mechanism for improving care for people with LTCs; this could be conducted within an implementation study.Trial registrationCurrent Controlled Trials ISRCTN98973169

The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics From 10-100 AU
We present a statistical analysis of the first 300 stars observed by the
Gemini Planet Imager Exoplanet Survey (GPIES). This subsample includes six
detected planets and three brown dwarfs; from these detections and our contrast
curves we infer the underlying distributions of substellar companions with
respect to their mass, semi-major axis, and host stellar mass. We uncover a
strong correlation between planet occurrence rate and host star mass, with
stars M 1.5 more likely to host planets with masses between 2-13
M and semi-major axes of 3-100 au at 99.92% confidence. We fit a
double power-law model in planet mass (m) and semi-major axis (a) for planet
populations around high-mass stars (M 1.5M) of the form , finding = -2.4 0.8 and
= -2.0 0.5, and an integrated occurrence rate of %
between 5-13 M and 10-100 au. A significantly lower occurrence rate
is obtained for brown dwarfs around all stars, with 0.8% of
stars hosting a brown dwarf companion between 13-80 M and 10-100
au. Brown dwarfs also appear to be distributed differently in mass and
semi-major axis compared to giant planets; whereas giant planets follow a
bottom-heavy mass distribution and favor smaller semi-major axes, brown dwarfs
exhibit just the opposite behaviors. Comparing to studies of short-period giant
planets from the RV method, our results are consistent with a peak in
occurrence of giant planets between ~1-10 au. We discuss how these trends,
including the preference of giant planets for high-mass host stars, point to
formation of giant planets by core/pebble accretion, and formation of brown
dwarfs by gravitational instability.Comment: 52 pages, 18 figures. AJ in pres
