Influence of sterilization, drying and oat bran enrichment of pasta on glucose and insulin responses in healthy subjects and on the rate and extent of in vitro starch digestion.

The effects of sterilization and oat bran enrichment of pasta on the glucose and insulin responses in healthy subjects were evaluated. Cooked and canned spaghetti and cooked fettucini without and with enrichment with oat bran (28%) were compared. Further, the effects of various low- and high-temperature drying conditions for spaghetti, cooking time and sterilization on the starch digestion rate and content of enzyme-resistant starch (RS) in vitro were also studied. Various cooking quality data were also determined to allow interpretation of results. The incremental glucose area (0-120 min) produced by canned spaghetti was twice the area of that produced by cooked spaghetti (69.03 vs 35.45 mmol/l x min, P less than 0.01). The incremental insulin area (0-120 min) was also significantly higher with canned spaghetti (17,500 vs 12,600 pmol/l x min, P less than 0.05). The rapid digestion was caused by excessive swelling of starch during sterilization that promoted a very soft texture of the spaghetti. Enrichment of fettucini with oat bran reduced slightly the incremental insulin area (15,600 vs 20,100 pmol/l x min, P less than 0.05, for 0-120 min), but did not significantly reduce the glucose area. Drying conditions and cooking times could be varied within broad limits without affecting the rate of starch digestion in vitro of cooked spaghetti. In sterilized spaghetti the content of resistant starch was higher than that found in cooked 'al dente' spaghetti (2.2-3.4 vs 0.5 mg/100 mg total starch). In conclusion, sterilization influences the nutritional properties of starch in pasta by substantially increasing the glucose and insulin responses and by formation of resistant starch. The effect of oatbran environment is restricted mainly to a slight decrease in the insulin response.     

A protocol for the urine dipstick/pad method.

The urinary tract accounts for nearly one third of all infections in the long-term care setting. This article reviews factors that influence nitrite and leukocyte esterase results obtained from traditional urine dipstick analysis for assessment of urinary tract infections in elderly long-term care residents. This article also proposes a protocol for a urine dipstick pressed into an incontinence pad as an alternative to dipstick analysis of a clean-catch or catheterized urine specimen.     

Genetic services for men: the preferences of men with a family history of prostate cancer.

PURPOSE: Men have a lower uptake of genetic services than women; however, the specific needs and preferences of men at risk of genetic conditions other than hereditary breast ovarian cancer are not known. We ascertain the information preferences of men with a family history of prostate cancer. METHODS: Unaffected men and their partners were administered a written questionnaire. RESULTS: Responses were received from 280 men (response rate: 59.2%) and 174 partners (response rate: 74%). Most men (59.6%) reported having insufficient information about their risk and wanted further information about personal risk (93.2%) and risk management (93.6%). Strikingly, 56.3% preferred to receive information related only to positive outcomes. Urologists were the preferred source of information, but there was considerable interest in a multidisciplinary service approach significantly associated with the number of affected relatives (odds ratio = 1.94, P < .002). Partners' level of concern was not associated with interest in multidisciplinary services, satisfaction with information, or support received. CONCLUSIONS: Delivering services to men at risk will require a multifaceted approach by primary care providers and specialists. Challenges include meeting men's expectations in the face of uncertain medical knowledge, engaging those at high risk in multidisciplinary services, and delivering tailored information to those at lower risk.     

Is there an association between periodontal condition and HIV infection?

Abstract Individuals in Tanzania who have limited access to medical and dental treatment provide an opportunity to study the natural association between periodontal condition and HIV infection and the stage of infection. 119 HIV infected adult individuals and 73 individuals with AIDS from the AIDS Clinical Trial Clinic at Muhimbili Medical Centre (MMC) in DaresSalaam participated as cases. Mean age was 35.3 and 35.1 years, respectively. 156 individuals with a mean age of 28.3 years, confirmed as HIV seronegative, served as controls. There were no significant differences in bleeding on probing, pocket formation or attachment loss among the HIV seronegative individuals. HIV seropositive and AIDS patients. We applied multiple logistic regression to calculate odds ratios for presence of periodontal conditions adjusting for age, gender and DMFT. Our odds ratios did not reveal any significant associations between bleeding on probing, pocket formation or attachment loss with regard to lymphocyte and CD4+ T cell counts among the HIV infected individuals and AIDS patients. When associations were investigated with regard to HIV serostatus (HIV seronegative. HIV seropositive or AIDS), our adjusted odds ratios were insignificant, too. In fact, most odds ratios were close to 1. Thus, our study supports recent views that the presence, extent and severity of periodontal disease among HIV infected individuals, may be less that hitherto thought.     

Addressing Couples' Sexuality Concerns During the Childbearing Period: Use of the PLISSIT Model

During pregnancy, a couple may benefit from discussing sexuality concerns with a nurse. Couples indicate they do not receive this support, and frequently nurses state they do not have the knowledge, time, or skills to provide patient education regarding sexuality. The PLISSIT model provides a framework for developing and implementing interventions to assist clients in maintaining their sexual relationship throughout the childbearing experience.     

A Neuroanatomical Construct for the Amnesic Effects of Propofol

Background: This study was designed to identify neuroanatomical locations of propofol's effects on episodic memory by producing minimal and maximal memory impairment during conscious sedation. Drug-related changes in regional cerebral blood flow (rCBF) were located in comparison with rCBF increases during a simple word memory task.

Methods: Regional cerebral blood flow changes were assessed in 11 healthy volunteers using H215O positron emission tomography (PET) and statistical parametric mapping (SPM99) at 600 and 1,000 ng/ml propofol target concentrations. Study groups were based on final recognition scores of auditory words memorized during PET scanning. rCBF changes during propofol administration were compared with those during the word memory task at baseline.

Results: Nonoverlapping memory effects were evident: low (n = 4; propofol concentration 523 +/- 138 ng/ml; 44 +/- 13% decrement from baseline memory) and high (n = 7; 829 +/- 246 ng/ml; 87 +/- 6% decrement from baseline) groups differed in rCBF reductions primarily in right-sided prefrontal and parietal regions, close to areas activated in the baseline memory task, particularly R dorsolateral prefrontal cortex (Brodmann area 46; x, y, z = 51, 38, 22). The medial temporal lobe region exhibited relative rCBF increases.     

Self‐Neglect: A Proposed New NANDA Diagnosis

PURPOSE. To propose a new NANDA diagnosis, self‐neglect. DATA SOURCES. Research studies and literature published from a variety of disciplines including nursing as well as primary research. DATA SYNTHESES. This diagnosis can be used to describe a constellation of self‐care problems of varying severity and impact on the health and well‐being of people who self‐neglect. Included are two subtypes of self‐neglect based on the degree of intentionality. Clarification of self‐neglect is long overdue because self‐neglect presents conceptual, identification, and intervention problems for nurses, healthcare workers, and for medicolegal systems across settings and in many countries. CONCLUSION. The proposed diagnosis, self‐neglect, fills a gap in current standardized terminology. This diagnosis will contribute significantly to nurses leading the way in the explication of an interdisciplinary and international health concern. PRACTICE AND POLICY IMPLICATIONS. Developing self‐neglect as a recognized nursing label is vital to clinicians and policy makers within and across countries. Appreciating less serious/non‐life‐threatening presentations will give nurses a care perspective to improve the health and well‐being of those in earlier stages of self‐neglect. Definitions for this phenomenon will contribute to care planning and interventions, leading to consistency in practice and research.
