Critical Role of Nutrition in Improving Quality of Care

The current era of healthcare delivery, with its focus on providing high‐quality, affordable care, presents many challenges to hospital‐based health professionals. The prevention and treatment of hospital malnutrition offer a tremendous opportunity to optimize the overall quality of patient care, improve clinical outcomes, and reduce costs. Unfortunately, malnutrition continues to go unrecognized and untreated in many hospitalized patients. This article represents a call to action from the interdisciplinary Alliance to Advance Patient Nutrition to highlight the critical role of nutrition intervention in clinical care and to suggest practical ways to promptly diagnose and treat malnourished patients and those at risk for malnutrition. We underscore the importance of an interdisciplinary approach to addressing malnutrition both in the hospital and in the acute posthospital phase. It is well recognized that malnutrition is associated with adverse clinical outcomes. Although data vary across studies, available evidence shows that early nutrition intervention can reduce complication rates, length of hospital stay, readmission rates, mortality, and cost of care. The key is to systematically identify patients who are malnourished or at risk and to promptly intervene. We present a novel care model to drive improvement, emphasizing the following 6 principles: (1) create an institutional culture where all stakeholders value nutrition, (2) redefine clinicians’ roles to include nutrition care, (3) recognize and diagnose all malnourished patients and those at risk, (4) rapidly implement comprehensive nutrition interventions and continued monitoring, (5) communicate nutrition care plans, and (6) develop a comprehensive discharge nutrition care and education plan.     

左肺移植的实验研究

目的为临床肺移植积累经验。方法分析总结29例犬左肺移植的资料。其中15例的供体肺用Euro-Collings液在4℃下保存6h,14例用UW液保存22～25h,作同种异体移植,并阻断受体的右肺动脉,以测定移植左肺的功能。结果所有的移植左肺均能胜任气体交换,循环稳定。结击本左肺移植方法可靠,可供临床应用时参考。     

Organ culture model for the study of HVH-II infections in carcinoma of the cervix.

An experimental model is described whereby human and monkey cervical tissues may be maintained as organ cultures for 21 and 40 days, respectively. Inclusion of sodium carboxymethyl cellulose in the culture medium prolongs the survival time of tissues considerably. The sequential cytologic changes associated with herpesvirus hominis type II (HVH-II) infection are reported. These changes are considered in relation to the possible causal role of HVH-II infection in cervical carcinogenesis.     

Assessment of FMR1 Gene Mutation at-Risk Status in Young Children

Fragile X syndrome (FXS), caused by a mutation of the FMR1 gene, is the most commonly inherited cause of developmental disability. Fragile X syndrome occurs relatively equally in all racial and ethnic groups and is one of the few disorders affecting child behavior for which the exact gene is identified. Furthermore, from infancy, both males and females with this syndrome are predisposed for manifesting characteristic cognitive, emotional, and behavioral challenges. The purpose of this article is to illuminate the multisystemic and multifaceted phenotype of the FMR1 gene mutation by means of the parent response Biopsychosocial Screening Inventory for Fragile X, for which preliminary studies show promise.     

Relation of herpesvirus hominis type II to carcinoma of the cervix. An animal model for the induction of long-term latency of herpesvirus hominis type II.

Proof of latency of herpesvirus hominis type II (HVH-II) following acute vaginocervical infection must be validated if it is to be considered an etiologic factor in carcinoma of the cervix. An animal model is presented which demonstrates acute HVH-II vaginocervical infection. Following the primary acute infection, animals maintained for an equivalent of 60 human years display persistance of the herpesvirus in the pelvic sensory ganglia. Evidence of the specificity of HVH-II as the infectious agent is presented.     

Clients Served and Services Provided by Academic Nurse-Managed Centers

Currently, no national database for academic nurse-managed centers (ANMCs) exists. These primary care services remain somewhat invisible in the policy and reimbursement areas of the American primary care system and, consequently, are undersupported. The purpose of this article is to describe client and service data from a national study of ANMCs. A cross-sectional survey design was used to collect data from ANMC directors. Usable data were received from 64 centers. ANMCs in the sample were relatively small in terms of patients and volume. Client and service profiles demonstrated variation, which seemed to be reflective of needs relative to populations and communities served. Nearly half of the ANMCs responding served clients of all ages, with services representing the breadth of primary care (i.e., health maintenance and management of minor acute and common chronic illnesses). Evidence of community-focused care was also noted. The reported use of standardized nursing language was low. Standardized medical taxonomies were more commonly used, with International Classification of Diseases, Ninth Revision being the most common. ANMCs provide a small but substantial amount of primary care services in communities served. Findings indicated a need for ANMCs to improve the documentation of their contributions through the use of standardized taxonomies to provide aggregated reporting for policy and research purposes.
