School-based prevention of depressive symptoms: A randomized controlled study of the effectiveness and specificity of the Penn Resiliency Program

The authors investigated the effectiveness and specificity of the Penn Resiliency Program (PRP; J. E. Gillham, L. H. Jaycox, K. J. Reivich, M. E. P. Seligman, & T. Silver, 1990), a cognitive-behavioral depression prevention program. Children (N = 697) from 3 middle schools were randomly assigned to PRP, Control (CON), or the Penn Enhancement Program (PEP; K. J. Reivich, 1996; A. J. Shatté, 1997), an alternate intervention that controls for nonspecific intervention ingredients. Children's depressive symptoms were assessed through 3 years of follow-up. There was no intervention effect on average levels of depressive symptoms in the full sample. Findings varied by school. In 2 schools, PRP significantly reduced depressive symptoms across the follow-up relative to both CON and PEP. In the 3rd school, PRP did not prevent depressive symptoms. The authors discuss the findings in relation to previous research on PRP and the dissemination of prevention programs.     

The South African universal preschool year: a case study of policy development and implementation

Background

South Africa is the first sub‐Saharan African country to legislate, fund and implement free preschool education. Human rights and restitution were at the forefront of the political struggle for democracy in South Africa. Levelling the playing fields by improving the school readiness of children disadvantaged by the racist policies of Apartheid is essential to the transformation of South African society.

Methods

A review of published and unpublished documents on Grade R was undertaken, and access and enrolment data come from the National Department of Basic Education's Education Management Information System (EMIS).

Results

A decade after initiation in 2005, 79% of 5‐year‐olds was enrolled in a preschool class; the vast majority of them in free public schools. Grade R is near universal and on track to becoming compulsory. It is part of the Foundation Phase (Grades 1–3) of schooling, falling under the Department of Basic Education, but also part of a broader national strategy to improve early child development under the direction of an Inter‐Departmental Steering. Evaluations demonstrate wide access to Grade R and high uptake, especially in the poorest areas. However, the quality of Grade R provision in these areas is not up to standard because of low levels of funding; inadequate training, supervision, remuneration and retention of Grade R teachers; insufficient learner support materials; and inadequate monitoring and quality assurance.

Conclusions

Lack of quality, amongst other factors, contributes to a widening school performance gap between children from more and less privileged areas. Quality of Grade R as well as earlier learning and subsequent years of schooling must be improved to achieve South Africa's aim to reduce poverty and inequality through, amongst others, parent and family involvement, learning in the home and preschool preparation.     

A case of slipped capital femoral epiphysis results from hypophosphatemic rickets： treatment and midterm follow-up

In this case, a male patient presented with a clinically and radiographieally unstable slipped capital femoral epiphysis （SCFE） as well as slipped calcaneal epiphysis years. Subsequent thorough at the age of 23 work-up revealed that he had some features of rickets and labo- ratory test demonstrated he had hypophos- phatemia （2.3mg/dl）, normocalcemia, normal vi- tamin D metabolite levels, and secondary hy- perparathyroidism.     

Neuronal Nitric Oxide Synthase (NOS1) Polymorphisms Interact with Financial Hardship to Affect Depression Risk

There is increasing evidence that genetic factors have a role in differential susceptibility to depression in response to severe or chronic adversity. Studies in animals suggest that nitric oxide (NO) signalling has a key role in depression-like behavioural responses to stress. This study investigated whether genetic variation in the brain-expressed nitric oxide synthase gene NOS1 modifies the relationship between psychosocial stress and current depression score. We recruited a population sample of 1222 individuals who provided DNA and questionnaire data on symptoms and stress. Scores on the List of Life-Threatening Experiences (LTE) questionnaire for the last year and self-rated current financial hardship were used as measures of recent/ongoing psychosocial stress. Twenty SNPs were genotyped. Significant associations between eight NOS1 SNPs, comprising two regional haplotypes, and current depression score were identified that survived correction for multiple testing when current financial hardship was used as the interaction term. A smaller three-SNP haplotypes (rs10507279, rs1004356 and rs3782218) located in a regulatory region of NOS1 showed one of the strongest effects, with the A-C-T haplotype associating with higher depression scores at low adversity levels but lower depression scores at higher adversity levels (p=2.3E-05). These results suggest that NOS1 SNPs interact with exposure to economic and psychosocial stressors to alter individual''s susceptibility to depression.     

Growth Hormone (GH) Secretion in Primary Adrenal Insufficiency: Effects of Cortisol Withdrawal and Patterned Replacement on GH Pulsatility and Circadian Rhythmicity

We studied the effects of cortisol withdrawal and patterned replacement upon spontaneous GH secretion and circadian rhythmicity in 7 patients with Addison's disease. Hydrocortisone was administered in physiological daily total dosages, and all resulting plasma cortisol values were 2–15 g/dl. It was given in 3 pulsatile modes: simulating physiological rhythm, reverse diurnal rhythmicity and continuous pulsatility. All modes of cortisol administration increased mean 24h, GH pulse amplitude and interpulse GH levels. During saline infusions circadian GH rhythmicity was preserved, with GH being at its highest between 2400–0400 h. Administration of hydrocortisone in any mode did not modify circadian GH rhythmicity. We conclude: Cortisol replacement in physiological daily doses increases GH output in patients with Addison's disease by augmenting GH pulse amplitude and interpulse levels. This is likely due to the attenuation of hypothalamic somatostatin (SRIF) secretion by physiologic levels of cortisol. By inference, it implies that cortisol deficiency leads to diminution of GH output with low GH pulse amplitude, likely as a result of an augmented hypothalamic somatostatin secretion. However, circadian rhythmicity of GH secretion is glucocorticoid-independent.     

An epidemiologic and demographic study of inflammatory bowel disease in black patients

Fifty-eight cases of blacks with inflammatory bowel disease were located in a file containing 1557 patients with these disorders. Certain epidemiologic and demographic characteristics of the two groups, blacks and whites, were compared, including distribution of cases, age at onset, sex incidence, occupational history, marital status, and educational level. No differences were found. Blacks were more likely to have arthritic symptoms and peptic ulcer disease if they had ulcerative colitis. Blacks with Crohn's disease had more fissures than whites. It appears that, once manifested, these diseases are similar in the two groups studied.     

Rural physicians: a survey analysis of HIV/AIDS patient management

Primary care physicians in South Carolina were asked about their knowledge, attitudes, beliefs, and services provided to HIV/AIDS patients. The study focused on conditions under which physicians would provide additional services in an effort to develop more effective state policies regarding HIV/AIDS. There was a 66 percent (597/900) response rate. This analysis focuses on a group of 338 physicians that identified themselves as rural (nonurban) physicians. Of the rural physicians responding, 42 percent had not treated a case of HIV/AIDS during the last year and 52 percent had seen only 1 to 9 patients. They identified lack of specialty back-up support, likelihood of losing patients, legal and ethical issues, and lack of community services as the primary barriers to service. Gaps in rural physician knowledge included when to refer HIV/AIDS cases to specialists and information on legal and ethical issues. They, like their urban colleagues, would provide additional services to HIV/AIDS patients with specialty back-up (57 percent), better community and social services support (54 percent), additional training (48 percent), and limited liability (47 percent). The authors conclude that policy changes addressing these areas in the broader contexts of rural health issues would expand access to care for persons with HIV infection in rural states.
