Nutrition risk and associated factors in congregate meal participants in northern Florida: role of Elder Care Services (ECS)

Nutrition is a key for extending quality of life of the elderly. Factors associated with nutritional risk in elders were identified with a modified nutrition screen initiative checklist. High, moderate and low nutritional risk was seen in 31, 46 and 23%, respectively, of 324 elders in six congregate meal sites in northern Florida. High nutritional risk was associated with urban residency, females, being African American, self-reported poor health and irregular visits to medical/health professionals. African American females living in urban areas with limited access to health care are most vulnerable.     

“Paradoxical” effects of morphine on antipredator defense reactions in wild and laboratory rats

In a Fear/Defense Test Battery, measuring defensive reactions to a present, approaching and contacting predator, the highest dose of morphine tested (7.5 mg/kg) reliably reduced vocalization to dorsal contact, to vibrissae stimulation, and to an anesthetized conspecific in laboratory-bred wild R. norvegicus. Except for a dose-dependent reduction in flinch/jump reactions to dorsal contact (taps), other defensive behaviors (flight, freezing, etc.) were not reliably altered by morphine treatment (0, 1.0, 2.5, 7.5 mg/kg). Vocalization responses to vabrissae stimulation in wild-trappedR. rattus were reliably increased following naloxone (1.0 and 10.0 mg/kg) administration, lending support for opiate receptor involvement in the mediation of defensive vocalization. In the Anxiety/Defense Test Battery, measuring defensive reactions to situations associated with a predator (cat) or with cat odor, laboratory rats showed no decrease in defensive behavior with morphine (0, 1.0, 5.0 mg/kg). In direct contrast to the above findings, the effects of morphine treatment in this test battery suggested a generalized increase in defensiveness to noncontacting and nonpainful threat stimuli. These effects included a decrease in time spent near the cat compartment, with a complementary increase in time spent at maximum distance, a decrease in transits between these sections, an increase in crouching, and a decrease in grooming and rearing. This pattern of results suggests that morphine may have two opposing effects of defensive behavior, a generalized enhancement, together with a more specific reduction of responses to tactile or painful stimulation. A very widespread pattern of reliable sex or sex × drug effects in the Anxiety/Defense Test Battery was in good agreement with previous report of sex differences in these tests, with females generally more defensive than males. Consonant with previous findings, no reliable sex differences were found with the Fear/Defense Test Battery, although several values approached an acceptable level of statistical significance.     

Tooth loss among older adults according to poverty status in the United States from 1999 through 2004 and 2009 through 2014

Background

As tooth loss decreases in an aging United States, retaining enough natural teeth for function is important for quality of life.

Is Gestational Weight Gain Associated with Diet Quality During Pregnancy?

The gestational weight gain (GWG) guidelines of the Institute of Medicine (IOM) aim to optimize birth outcomes and reduce pregnancy complications. The GWG guidelines are set based on the prepregnancy weight status and optimal weight gain at different trimesters of pregnancy. Dietary references intakes (DRIs) of the IOM are set for each trimester of pregnancy for energy intake and other essential nutrients by age groups (≤18, 19–30, 31–51 years). The DRIs, however, do not take into account the differing energy and nutrient requirements of women with different prepregnancy weights. In this cross-sectional study, we tested the hypothesis that diet quality during pregnancy is associated with adequate GWG at different stages of pregnancy. Diet quality during pregnancy was assessed from a 24-h recall measured by the healthy eating index of 2005 (HEI-2005). Both GWG and diet quality data were from 490 pregnant women aged 16–43 years included in National Health and Nutrition Examination Survey 2003–2006, a program of studies designed to assess the health and nutritional status of adults and children in the US, during which pregnant women were oversampled. Logistic regression models adjusted for age, trimester of gestation, race/ethnicity, education level, marital status, family poverty income ratio, daily supplement use, physical activity, and prepregnancy BMI were used to investigate if HEI-2005 is a determinant of GWG status at different trimesters of pregnancy. We found that HEI-2005 scores were not determinants of adequate GWG, although inadequate intake of total vegetables (OR 3.8, CI 1.1–13.2, p = 0.03) and oils were associated with excessive GWG (OR 2.8, CI 1.2–6.4, p = 0.02) when covariates were controlled. Although adequate GWG was not associated with diet quality as measured by HEI-2005 during pregnancy in this study, comprehensive prenatal counseling is still important to reduce adverse birth outcomes.     

The impact of nutrition intervention on a reliable morbidity and mortality indicator: the hemodialysis-prognostic nutrition index.

OBJECTIVE: To determine the prevalence of risk for hospitalization in hemodialysis (HD) patients and examine the impact of oral kilocalorie and protein supplementation in two Midwestern outpatient dialysis centers. DESIGN/SETTING: This was a prospective intervention study conducted at 2 outpatient dialysis centers in the Midwest. PATIENTS: The inclusion criteria for patients were (1) more than 18 years of age, (2) receiving HD 3 times per week, and (3) a functioning gastrointestinal tract. INTERVENTION: Patients who met study criteria and signed an informed consent form were screened using the hemodialysis prognostic nutrition index (HD-PNI) to determine risk for hospitalization. Patients determined to be at high risk (HD-PNI > or =0.8) were included in the treatment group, and patients at low risk did not receive the intervention. They followed their normal nutritional regimen. The intervention group received an oral supplement daily for 3 months. The team of the dietitian, patient, researcher, and physician determined the type of oral supplements based on patient needs and preferences. MAIN OUTCOME MEASURES: Before and after HD-PNI, 24-hour recall and subjective global assessments (SGA) were conducted to assess risk for hospitalization, dietary intake, and nutritional status, respectively. RESULTS: A total of 117 patients were screened, with a total of 26 in the treatment group (high risk) and 91 in the low-risk group. Baseline SGA distribution was 23% for patients with low nutritional risk (group A), 64% for those with moderate nutritional risk (group B), and 13% for those with severe nutritional risk (group C). When the HD-PNI scores of the treatment group were analyzed using paired t-tests, significant differences were observed between pre- and post-HD-PNI mean scores, 1.92 +/- 1.16 and 1.42 +/- 1.59, (P <.05) respectively. When comparing the responders versus the nonresponders by the dependent and independent variables (pre- and post-HD-PNI, SGA, kilocalorie intake, diabetic status, and presence of hypertension) only post-HD-PNI score was significantly different (0.96 +/- 1.69 and 2.20 +/- 1.09, respectively). CONCLUSION: This study succeeded in showing that 22% of the hemodialysis patients in 2 Midwestern centers were at an increased risk for hospitalization. Furthermore, dietitian intervention with oral kilocalorie and protein supplements decreased the patients' hemodialysis prognostic nutrition index scores and thereby decreased the patients' risks for hospitalization.
