Improving the retention rate of newly graduated nurses.

Newly graduated nurses often finish orientation and then believe they still need more support and mentoring than is available. Retention rates suffer as they think it must be better elsewhere. This article reports a community hospital's implementation of an education-based preceptor program. A convenience sample of 40 new graduates participated in the study. Qualitative and quantitative findings indicate a high level of satisfaction (mean visual analogue scale score 93.7), 29% increase in retention, and 9.5% decrease in vacancy.     

Longitudinal relationships between lexical and grammatical development in typical and late-talking children.

PURPOSE: This study examined the longitudinal relationships between lexical and grammatical development in typically developing (TD) and late-talking children for the purposes of testing the single-mechanism account of language acquisition and comparing the developmental trajectories of lexical and grammatical development in late-talking and TD children. METHOD: Participants included 30 children identified as late talkers (LTs) at 2;0 (years;months), and 30 TD children matched on age, nonverbal cognition, socioeconomic status, and gender. Data were collected at 5 points between 2;0 and 5;6. RESULTS: Cross-lagged correlational analyses indicated that TD children showed evidence of bidirectional bootstrapping between lexical and grammatical development between 2;0 and 3;6. Compared with the TD group, LTs exhibited less evidence of syntactic bootstrapping. Linear mixed-effects modeling of language sample data suggested that the relationship between lexical and grammatical growth was similar for the 2 groups. CONCLUSION: Lexical and grammatical development were strongly related in both groups, consistent with the single-mechanism account of language acquisition. The results were mixed in terms of finding longitudinal differences in lexical-grammatical relationships between the TD and late-talking children; however, several analyses suggested that for late-talking children, syntactic growth may be less facilitative of lexical development.     

Genetic polymorphisms in dopamine-related genes and smoking cessation in women: a prospective cohort study

Background  

Genes involved in dopaminergic neurotransmission have been suggested as candidates for involvement in smoking behavior. We hypothesized that alleles associated with reduced dopaminergic neurotransmission would be more common in continuing smokers than among women who quit smoking.     

Fire in the operating theatre. Evacuation pre–planning may save lives

An operating theatre fire and the steps taken to deal with it are described; the difficulties encountered in evacuating anaesthetised patients are highlighted. Measures which might be taken to prevent recurrence of these problems, and recommendations on the institution of fire drills for the safety of patients and staff are given.     

Identification of Alcohol Abuse and Alcoholism with Biological Parameters

The prevalence and incidence of heavy alcohol consumption are major problems which have been increasing in many countries in recent years. It is crucial for physicians to consistently identify early drinking problems as well as the various end disease states in order to minimize suffering and maximize recovery. This paper reviews the evolutionary development of clinical tools for detection of alcohol abuse. The focus is primarily on clinical/biochemical indicators of alcohol abuse, emphasizing but not limited to changes in hematological characteristics, liver enzyme activity, lipids, immune function factors, hormones, neurological factors, and some physically based tests. Use of test combinations and sophisticated statistical analysis of pattern changes in test batteries evidence increased diagnostic efficiency.     

ACARDIAC TWIN FETUS WITH SEVERE HYDROPS FETALIS AND BILATERAL TALIPES VARUS DEFORMITY

Twin reversed-arterial-perfusion syndrome (TRAPS) is a rare complication of monochorionic twin pregnancies. TRAPS is characterized by the hemodynamic dependence of a “recipient” twin from a “pump” twin. The “recipient” twin exhibits lethal abnormalities, such as acardia and acephaly. Circulatory failure of the normal twin derives from the existence of arterio-arterial and veno-venous anastomoses within the placenta that allow retrograde perfusion of the acardiac twin by blood coming from the normal twin. Acardiac twinning is the most extreme manifestation of the twin-twin transfusion syndrome. This occurs in 1 in 100 monozygotic twin pregnancies and 1 in 35,000 births. We report a case of diamnionic monochorionic female twins in which the acardiac twin demonstrated severe hydrops fetalis and bilateral talipes varus deformity. Cesarean section was performed on a 27-year-old hypertensive gravida 2, para 1 mother for fetal indications at 32 6/7 weeks gestation. The acardiac fetus had a two-vessel umbilical cord measuring 43.5 cm in length and 0.8 cm in diameter. The proximal end inserted into the root of the normal twin's umbilical cord in an acute angle forming a “v” close to the placental disc. Structures rostral to the thorax were absent except for a round mass of flesh with three small buds in place of the head and neck, and bilateral upper extremities. Only the kidneys, right adrenal, small and large intestine, and rudimentary urinary bladder were present. Both feet demonstrated talipes varus deformity. The fetus was severely hydropic. The subcutaneous fat measured 4.5 cm in maximum thickness. The normal twin had a protracted course complicated with respiratory distress syndrome, moderate secundum atrial septal defect with left to right shunt, and thrombocytopenia of prematurity. The baby was eventually discharged after approximately 1 month. At the time of this report, 5 months postpartum, the neonate is growing and developing normally. To our knowledge, this is the first report of severe hydrops fetalis and talipes varus deformity in an acardiac twin.
