Mental health care needs and preferences for mothers of children with a disability

BACKGROUND

Mothers of children with a disability are at increased risk of poor mental health compared with mothers of typically developing children. The aim of the study was to describe the mental health care needs and preferences for support of mothers of children and young people aged 0-25 years with a disability.

METHODS

A cross-sectional study was used, using an online survey with 294 mothers of children with a disability. Questions were asked about mental health, perceived need for support, barriers to accessing mental health care, and preferences for support. Descriptive and chi-squared analyses were performed.

RESULTS

High rates of mental ill health were self-identified in the previous 12 months, with reported clinically significant depression (44%), anxiety (42%), and suicidality (22%). Nearly half (48%) of the mothers reported high to very high psychological distress. Although 75% of mothers perceived a need for professional support, only 58% attempted to access this. Key barriers to accessing support were caregiving duties making it difficult to schedule appointments (45%) and not perceiving the mental health problem as serious enough to require help (36%). Individual counselling was the preferred type of support (66%) followed by professionally guided relaxation (49%) and education about mental health (47%). Support was considered most critical at the time of diagnosis and during medical intervention for their child.

CONCLUSIONS

Although mental health problems were common and mothers perceived the need for professional help, several key barriers were preventing mothers from accessing help. Our study suggests that improving mothers' knowledge of when and where to seek help (mental health literacy) may encourage their access to support. There also needs to be more accessible treatment to mothers given the high care demands that are placed upon them.

Robust, tunable, and high purity triggered single photon source at room temperature using a nitrogen-vacancy defect in diamond in an open microcavity

We report progress in the development of tunable room temperature triggered single photon sources based on single nitrogen-vacancy (NV) centres in nanodiamond coupled to open access optical micro-cavities. The feeding of fluorescence from an NV centre into the cavity mode increases the spectral density of the emission and results in an output stream of triggered single photons with spectral line width of order 1 nm, tunable in the range 640 - 700 nm. We record single photon purities exceeding 96% and estimated device efficiencies up to 3%. We compare performance using plano-concave microcavities with radii of curvature from 25 μm to 4 μm and show that up to 17% of the total emission is fed into the TEM₀₀ mode. Pulsed Hanbury-Brown Twiss (HBT) interferometry shows that an improvement in single photon purity is facilitated due to the increased spectral density.

Isolated Lateral Meniscal Tear in the Dog

degenerative changes of the involved stifle joint associated with a “bucket handle” tear of the caudal body of the lateral meniscus. Surgical excision of the torn section of meniscus was beneficial in the first patient but this patient had persistant difficulty with the leg after exercise. Gross and microscopic pathology of the involved stifle in the second patient showed the meniscal lesion to be associated with severe cartilage fibrillation of the overlying lateral femoral condyle. As in human beings, the mechanism of injury may have been placement of the foot during vigorous external rotation of the femur with the stifle flexed. Extension of the limb from this position could have resulted in an isolated tear of the lateral meniscus.

Bayesian Networks to Compare Pest Control Interventions on Commodities Along Agricultural Production Chains

The production of an agricultural commodity involves a sequence of processes: planting/growing, harvesting, sorting/grading, postharvest treatment, packing, and exporting. A Bayesian network has been developed to represent the level of potential infestation of an agricultural commodity by a specified pest along an agricultural production chain. It reflects the dependency of this infestation on the predicted level of pest challenge, the anticipated susceptibility of the commodity to the pest, the level of impact from pest control measures as designed, and any variation from that due to uncertainty in measure efficacy. The objective of this Bayesian network is to facilitate agreement between national governments of the exporters and importers on a set of phytosanitary measures to meet specific phytosanitary measure requirements to achieve target levels of protection against regulated pests. The model can be used to compare the performance of different combinations of measures under different scenarios of pest challenge, making use of available measure performance data. A case study is presented using a model developed for a fruit fly pest on dragon fruit in Vietnam; the model parameters and results are illustrative and do not imply a particular level of fruit fly infestation of these exports; rather, they provide the most likely, alternative, or worst-case scenarios of the impact of measures. As a means to facilitate agreement for trade, the model provides a framework to support communication between exporters and importers about any differences in perceptions of the risk reduction achieved by pest control measures deployed during the commodity production chain.

Women in academic psychiatry in the United Kingdom

Although there seems to be a shared impression that the proportion of women in academic psychiatry is substantially lower than in National Health Service (NHS) posts, we are not aware of any empirical data on this. In the USA, women physicians have been shown to be more likely to pursue an academic career than men (Nonnemaker, 2000), but the number who advance to Professor appears significantly lower than expected (Reiser et al, 1993; Nonnemaker, 2000). Women in academic psychiatry in Canada also appear less likely to advance to senior positions than their male colleagues (Penfold, 1987). A recent survey of 44 academic institutions in the UK, carried out by the National Centre for Social Research (Blake & La Valle, 2000), found that women occupied lower grade academic posts than their male counterparts and therefore were less eligible to apply for project research grants. Those that were eligible were as successful in gaining funding as their male colleagues.

Variation in 'fast-track' referrals for suspected cancer by patient characteristic and cancer diagnosis: evidence from 670 000 patients with cancers of 35 different sites

BACKGROUND

In England, 'fast-track' (also known as 'two-week wait') general practitioner referrals for suspected cancer in symptomatic patients are used to shorten diagnostic intervals and are supported by clinical guidelines. However, the use of the fast-track pathway may vary for different patient groups.

METHODS

We examined data from 669 220 patients with 35 cancers diagnosed in 2006-2010 following either fast-track or 'routine' primary-to-secondary care referrals using 'Routes to Diagnosis' data. We estimated the proportion of fast-track referrals by sociodemographic characteristic and cancer site and used logistic regression to estimate respective crude and adjusted odds ratios. We additionally explored whether sociodemographic associations varied by cancer.

RESULTS

There were large variations in the odds of fast-track referral by cancer (P<0.001). Patients with testicular and breast cancer were most likely to have been diagnosed after a fast-track referral (adjusted odds ratios 2.73 and 2.35, respectively, using rectal cancer as reference); whereas patients with brain cancer and leukaemias least likely (adjusted odds ratios 0.05 and 0.09, respectively, for brain cancer and acute myeloid leukaemia). There were sex, age and deprivation differences in the odds of fast-track referral (P<0.013) that varied in their size and direction for patients with different cancers (P<0.001). For example, fast-track referrals were least likely in younger women with endometrial cancer and in older men with testicular cancer.

CONCLUSIONS

Fast-track referrals are less likely for cancers characterised by nonspecific presenting symptoms and patients belonging to low cancer incidence demographic groups. Interventions beyond clinical guidelines for 'alarm' symptoms are needed to improve diagnostic timeliness.

A pilot randomized controlled trial comparing effectiveness of prism glasses, visual search training and standard care in hemianopia

OBJECTIVE

Pilot trial to compare prism therapy and visual search training, for homonymous hemianopia, to standard care (information only).

METHODS

Prospective, multicentre, parallel, single-blind, three-arm RCT across fifteen UK acute stroke units.

PARTICIPANTS

Stroke survivors with homonymous hemianopia.

INTERVENTIONS

Arm a (Fresnel prisms) for minimum 2 hours, 5 days per week over 6 weeks. Arm b (visual search training) for minimum 30 minutes, 5 days per week over 6 weeks. Arm c (standard care-information only).

INCLUSION CRITERIA

Adult stroke survivors (>18 years), stable hemianopia, visual acuity better than 0.5 logMAR, refractive error within ±5 dioptres, ability to read/understand English and provide consent.

OUTCOMES

Primary outcomes were change in visual field area from baseline to 26 weeks and calculation of sample size for a definitive trial. Secondary measures included Rivermead Mobility Index, Visual Function Questionnaire 25/10, Nottingham Extended Activities of Daily Living, Euro Qual, Short Form-12 questionnaires and Radner reading ability. Measures were post-randomization at baseline and 6, 12 and 26 weeks.

RANDOMIZATION

Randomization block lists stratified by site and partial/complete hemianopia.

BLINDING

Allocations disclosed to patients. Primary outcome assessor blind to treatment allocation.

RESULTS

Eighty-seven patients were recruited: 27-Fresnel prisms, 30-visual search training and 30-standard care; 69% male; mean age 69 years (SD 12). At 26 weeks, full results for 24, 24 and 22 patients, respectively, were compared to baseline. Sample size calculation for a definitive trial determined as 269 participants per arm for a 200 degree² visual field area change at 90% power. Non-significant relative change in area of visual field was 5%, 8% and 3.5%, respectively, for the three groups. Visual Function Questionnaire responses improved significantly from baseline to 26 weeks with visual search training (60 [SD 19] to 68.4 [SD 20]) compared to Fresnel prisms (68.5 [SD 16.4] to 68.2 [18.4]: 7% difference) and standard care (63.7 [SD 19.4] to 59.8 [SD 22.7]: 10% difference), P=.05. Related adverse events were common with Fresnel prisms (69.2%; typically headaches).

CONCLUSIONS

No significant change occurred for area of visual field area across arms over follow-up. Visual search training had significant improvement in vision-related quality of life. Prism therapy produced adverse events in 69%. Visual search training results warrant further investigation.
