First Dark Matter Constraints from a SuperCDMS Single-Charge Sensitive Detector.

We present the first limits on inelastic electron-scattering dark matter and dark photon absorption using a prototype SuperCDMS detector having a charge resolution of 0.1 electron-hole pairs (CDMS HVeV, a 0.93 g CDMS high-voltage device). These electron-recoil limits significantly improve experimental constraints on dark matter particles with masses as low as 1 MeV/c^{2}. We demonstrate a sensitivity to dark photons competitive with other leading approaches but using substantially less exposure (0.49 g d). These results demonstrate the scientific potential of phonon-mediated semiconductor detectors that are sensitive to single electronic excitations.

Primary care physicians' and psychiatrists' approaches to treating mild depression.

OBJECTIVE: To measure how primary care physicians (PCPs) and psychiatrists treat mild depression. METHOD: We surveyed a national sample of US PCPs and psychiatrists using a vignette of a 52-year-old man with depressive symptoms not meeting Major Depressive Episode criteria. Physicians were asked how likely they were to recommend an antidepressant counseling, combined medication, and counseling or to make a psychiatric referral. RESULTS: Response rate was 896/1427 PCPs and 312/487 for psychiatrists. Compared with PCPs, psychiatrists were more likely to recommend an antidepressant (70% vs. 56%), counseling (86% vs. 54%), or the combination of medication and counseling (61% vs. 30%). More psychiatrists (44%) than PCPs (15%) were 'very likely' to promote psychiatric referral. PCPs who frequently attended religious services were less likely (than infrequent attenders) to refer the patient to a psychiatrist (12% vs. 18%); and more likely to recommend increased involvement in meaningful relationships/activities (50% vs. 41%) and religious community (33% vs. 17%). CONCLUSION: Psychiatrists treat mild depression more aggressively than PCPs. Both are inclined to use antidepressants for patients with mild depression.

Factors influencing physicians' advice about female sterilization in USA: a national survey.

BACKGROUND: Tubal ligation can be a controversial method of birth control, depending on the patient's circumstances and the physician's beliefs. METHODS: In a national survey of 1800 US obstetrician-gynecologist (Ob/Gyn) physicians, we examined how patients' and physicians' characteristics influence Ob/Gyns' advice about, and provision of, tubal ligation. Physicians were presented with a vignette in which a patient requests tubal ligation. The patient's age, gravida/parity and her husband's agreement/disagreement were varied in a factorial experiment. Criterion variables were whether physicians would discourage tubal ligation, and whether physicians would provide the surgery. RESULTS: The response rate was 66% (1154/1760). Most Ob/Gyns (98%) would help the patient to obtain tubal ligation, although 9-70% would attempt to dissuade her, depending on her characteristics. Forty-five percent of physicians would discourage a G2P1 (gravida/parity) woman, while 29% would discourage a G4P3 woman. Most physicians (59%) would discourage a 26-year-old whose husband disagreed, while 32% would discourage a 26-year-old whose husband agreed. For a 36-year-old patient, 47% would discourage her if her husband disagreed, while only 10% would discourage her if her husband agreed. Physicians' sex had no significant effect on advice about tubal ligation. CONCLUSIONS: Regarding patients who seek surgical sterilization, physicians' advice varies based on patient age, parity and spousal agreement but almost all Ob/Gyns are willing to provide or help patients obtain surgical sterilization if asked. An important limitation of the study is that a brief vignette, while useful for statistical analysis, is a rough approximation of an actual clinical encounter.

Autonomy, religion and clinical decisions: findings from a national physician survey.

BACKGROUND: Patient autonomy has been promoted as the most important principle to guide difficult clinical decisions. To examine whether practising physicians indeed value patient autonomy above other considerations, physicians were asked to weight patient autonomy against three other criteria that often influence doctors' decisions. Associations between physicians' religious characteristics and their weighting of the criteria were also examined. METHODS: Mailed survey in 2007 of a stratified random sample of 1000 US primary care physicians, selected from the American Medical Association masterfile. Physicians were asked how much weight should be given to the following: (1) the patient's expressed wishes and values, (2) the physician's own judgment about what is in the patient's best interest, (3) standards and recommendations from professional medical bodies and (4) moral guidelines from religious traditions. RESULTS: Response rate 51% (446/879). Half of physicians (55%) gave the patient's expressed wishes and values "the highest possible weight". In comparative analysis, 40% gave patient wishes more weight than the other three factors, and 13% ranked patient wishes behind some other factor. Religious doctors tended to give less weight to the patient's expressed wishes. For example, 47% of doctors with high intrinsic religious motivation gave patient wishes the "highest possible weight", versus 67% of those with low (OR 0.5; 95% CI 0.3 to 0.8). CONCLUSIONS: Doctors believe patient wishes and values are important, but other considerations are often equally or more important. This suggests that patient autonomy does not guide physicians' decisions as much as is often recommended in the ethics literature.

Home-based versus hospital-based care for people with serious mental illness.

BACKGROUND: A controlled study tested whether the superior outcome of community care for serious mental illness (SMI) in Madison and in Sydney would also be found in inner London. METHOD: Patients from an inner London catchment area who faced emergency admission for SMI (many were violent or suicidal) were randomised to 20 months or more of either home-based care (Daily Living Programme, DLP; n = 92), or standard in-patient and later out-patient care (controls, n = 97). Most DLP patients had brief in-patient stays at some time. Measures included number and duration of in-patient admissions, independent ratings of clinical and social function, and patients' and relatives' satisfaction. RESULTS: Outcome was superior with home-based care. Until month 20, DLP care improved symptoms and social adjustment slightly more, and enhanced patients' and relatives' satisfaction. From 3 to 18 months DLP care greatly reduced the number of in-patient bed days as long as the DLP team was responsible for any in-patient phase its patients had. Cost was less. DLP care did not reduce the number of admissions, nor of deaths from self-harm (3 DLP, 2 control). One DLP patient killed a child. Even at 20 months many DLP and control patients still had severe symptoms, poor social adjustment, no job, and need for assertive follow-up and heavy staff input. (Beyond 20 months most gains were lost apart from satisfaction.) CONCLUSIONS: It is unclear how much the gain until 20 months from home-based care was due to its site of care, its being problem-centred, its teaching of daily living skills, its assertive follow-up, the home care team's keeping responsibility for any in-patient phase, its coordination of total care (case management), or to other care components. Home-based care is hard to organise and vulnerable to many factors, and needs careful training and clinical audit if gains are to be sustained.

Home-based versus out-patient/in-patient care for people with serious mental illness. Phase II of a controlled study.

BACKGROUND: The effect of a randomised controlled withdrawal of home-based care was studied for half of a sample of seriously mentally ill (SMI) patients from an inner London catchment area, compared with the effects of continuing home-based care. METHOD: Patients, aged 18-64, had entered the trial at month 0 when facing emergency admission for SMI. After at least 20 months home-based care (Phase I), patients were randomised at month 30 into Phase II (months 30-45) to have either further home-based care (DLPII, n = 33) or be transferred to out-/in-patient care (DLP-control, n = 33). They were assessed at 30, 34, and 45 months. Phase I control patients (n = 70) were assessed again at month 45. Measures used were number and duration of in-patient admissions, independent ratings of clinical and social function, and patients' and relatives' satisfaction. RESULTS: The slim clinical and social gains from home-based v. out-/in-patient care during Phase I were largely lost in Phase II. Duration of crisis admissions increased from Phase I to Phase II in both DLPII and DLP-control patients. During Phase II, patients' and relatives' satisfaction remained greater for home-based than out-/in-patient care patients. At 45 months, compared with the Phase I controls, DLPII patients and relatives were more satisfied with care. Such satisfaction was independent of clinical/social gains. CONCLUSIONS: The loss of Phase I gains were perhaps due to attenuation of home-based care quality and to benefits of Phase I home-based care lingering into Phase II in DLP-controls. The Phase II home-based care team suffered from low morale.

Community care: does it reduce the need for psychiatric beds? A comparison of two different styles of service in three hospitals.

The admission pattern of under-65s during the first seven years of Kidderminster's District General Hospital Psychiatric Department was compared with the last seven years of the mental hospital (Powick Hospital) which it superseded in July 1978, and with its nearest mental hospital (Barnsley Hall Hospital). In Kidderminster the average length of patient's hospital stay was half that at Barnsley Hall. There were more admissions per head of population, more which lasted less than a week, and more patients with over six admissions to Kidderminster than Barnsley Hall. The retrospective comparison with Powick Hospital showed that these differences were not due to the superior community facilities in Kidderminster since there was no real change in hospital bed use with the development of community services; this supports the view that there is a bed-rock of illness which will always need in-patient care however comprehensive the community resources.

Patterns of care in a district general hospital psychiatric department.

A survey of all admissions of patients under the age of 65 during the first 6 years of a District General Psychiatric Department without mental-hospital support is reported. Three high-uptake groups of in-patients were defined; the long-stay (12 months or more), the medium-stay (6-12 months), and the revolving-door group (more than three admissions in any period of 12 months). Identifying characteristics which distinguish between these groups were examined. During a 7-year period there was no accumulation of long-stay patients, and a striking lack of schizophrenic patients who remained in hospital for more than 6 months or who had more than three admissions in any twelve-month period. This was not accounted for by drift of the high-uptake groups out of contact with the service, but may be related both to the style of service provision and to the socially cohesive nature of the area under study. Local variation should be given due importance when community services are being developed.

Death attitudes and experiences of rehabilitation counselors.

A survey of the death attitudes and experiences of 54 rehabilitation counselors indicated that their personal beliefs could potentially influence service to disabled people, particularly in the areas of terminal illness and suicide. To balance such influence, contined training of counselors and research efforts concerning this problem are recommended.
