RESUMO

BACKGROUND: Early childhood represents a sensitive developmental period when trauma-informed care may mitigate the effects of trauma on developmental and health outcomes. However, few interventions use a low-literacy scalable approach to improve child trauma knowledge and attitudes among parents and early childcare and education caregivers. METHODS: Representatives from 24 early head start (EHS) and head start (HS) agencies attended a 2 day online train-the trainer session and then delivered a child trauma and resilience training to staff at their sites, with the option to deliver a similar training to parents. Baseline and 3 month post-training surveys assessed participant knowledge and attitudes regarding childhood trauma and resilience. Paired T-tests and chi2 analyses assessed changes in responses over time. RESULTS: Thousand five hundred sixty seven staff from 24 agencies and 443 parents from 7 agencies completed baseline and follow up surveys. Over 55% of parents reported their child had experienced at least one adverse childhood experience. Staff and parents had high knowledge regarding causes of trauma at baseline. Both staff and parents, demonstrated significant improvements in identifying symptoms of child trauma. Staff also improved knowledge of resiliency and toxic stress. Parents reported more positive attitudes towards trauma-informed parenting practices. CONCLUSION: This is the first training on childhood trauma among EHS/HS providers and parents using a low literacy train-the-trainer approach. Results suggest a potentially promising methodology with broad dissemination potential to prepare and train the one million plus teachers and caregivers in center-based settings and the parents and families who access them to recognize and respond to child trauma.

RESUMO

In dairy farming systems, growing winter crops for forage is frequently limited to annual grasses grown in monoculture. The objectives of this study were to determine how cropping grasses alone or in mixtures with legumes affects the yield, nutritional composition, and in vitro digestibility of fresh and ensiled winter crops and the yield, nutritional composition, and in vitro digestibility of the subsequent summer crops. Experimental plots were planted with 15 different winter crops at 3 locations in Virginia. At each site, 4 plots of each treatment were planted in a randomized complete block design. The 15 treatments included 5 winter annual grasses [barley (BA), ryegrass (RG), rye (RY), triticale (TR), and wheat (WT)] in monoculture [i.e., no legumes (NO)] or with 1 of 2 winter annual legumes [crimson clover (CC) and hairy vetch (HV)]. After harvesting the winter crops, corn and forage sorghum were planted within the same plots perpendicular to the winter crop plantings. The nutritional composition and the in vitro digestibility of winter and summer crops were determined for fresh and ensiled samples. Growing grasses in mixtures with CC increased forage dry matter (DM) yield (2.84 Mg/ha), but the yield of mixtures with HV (2.47 Mg/ha) was similar to that of grasses grown in monoculture (2.40 Mg/ha). Growing grasses in mixtures with legumes increased the crude protein concentration of the fresh forage from 13.0% to 15.5% for CC and to 17.3% for HV. For neutral detergent fiber (NDF) concentrations, the interaction between grasses and legumes was significant for both fresh and ensiled forages. Growing BA, RY, and TR in mixtures with legumes decreased NDF concentrations, whereas growing RG and WT with legumes did not affect the NDF concentrations of either the fresh or the ensiled forages. Growing grasses in mixtures with legumes decreased the concentration of sugars of fresh forages relative to grasses grown in monoculture. Primarily, this decrease can be attributed to low concentrations of sugars of mixtures with HV (10.5%). Growing grasses in mixtures with legumes reduced the fiber digestibility of both winter crops (75.7% to 72.8% NDF). Growing grasses in mixtures with legumes did not affect estimated DM yield, nutritional composition, or digestibility of the succeeding summer crops. In conclusion, growing grasses in mixtures with legumes as winter forage crops can increase forage estimated DM yields and its nutritional quality in dairy farming sytems.

RESUMO

Field experiments were conducted in 2004 and 2005 to determine the effect of different levels of hand-infested third instar European corn borer, Ostrinia nubilalis (Hiibner) (Lepidoptera: Crambidae), on whole-plant yield and plant growth stage in corn, Zea mays L., grown for silage. In 2004 and 2005, European corn borer infestation level had a significant negative impact on whole-plant yield (grams of dry matter per plant) with increasing infestation; however, whole-plant yield was not significantly affected by plant growth stage in either year. In 2004, the six larvae per plant treatment caused the greatest percentage of reduction (23.4%) in mean (+/-SEM) whole-plant yield (258.5 +/- 21.0 g dry matter per plant) compared with the Bacillus thuringiensis (Bt) CrylAb control (337.3 +/- 11.1 g dry matter per plant). In 2005, the five larvae per plant treatment caused the greatest percentage of reduction (8.3%) in mean whole-plant yield (282.3 +/- 10.8 g dry matter per plant) compared with the Bt CrylAb control (307.8 +/- 8.3 g dry matter per plant). The relationship between mean whole-plant yield and European corn borer larvae infestation level from the pooled data of both years was described well by using an exponential decay model (r2 = 0.84, P = 0.0038). The economic injury level for silage corn was estimated to be approximately 73% higher than for corn grown for grain based on similar control costs and crop values. In addition, plant growth stage and European corn borer infestation level had no effect on percentage of acid detergent fiber, neutral detergent fiber, and crude protein values in either year of the study.

RESUMO

The development of effective gene-therapeutic applications for cardiovascular disorders is in part limited by the lack of appropriate delivery systems. In an attempt to overcome this deficiency, we investigated the ability of baculoviral vectors to transduce human cardiovascular cells, for which data are missing in literature. Additionally, baculovirus ability to transduce target cells was compared to that of an adenoviral vector, a well characterized and widely used viral vector. Transduction experiments, performed using baculo/adenoviral vectors expressing the enhanced green fluorescence protein, revealed that, under the experimental condition considered, baculoviruses but not adenoviruses efficiently transduce human coronary smooth muscle cells (hCSMC); an opposite behavior was noticed for human coronary endothelial cells (hCEC). Thus, baculoviral vectors are potentially indicated as transfer system in the treatment of coronary restenosis, where growth inhibitory genes should reach hCSMC but not hCEC. When used to transduce human cardiomyocytes and fibroblasts, both vectors behaved similarly. Finally, studies on cellular DNA replication revealed a more prolonged and pronounced negative effect on cells transduced by adenoviral compared to baculoviral vectors. Our data indicate that baculoviruses represent an attractive alternative to adenoviruses as transfer vectors in cardiovascular cells and that baculovirus have the potential to be used as gene transfer system in cardiovascular diseases such as restenosis.

RESUMO

The presence of somatostatin receptors on TSH-secreting pituitary adenomas allows treatment of central hyperthyroidism with somatostatin analogs. Six women and 5 men (mean +/- SEM age, 43 +/- 3 yr) presented TSH-secreting pituitary adenomas (micro, n = 2; macro, n = 9). Seven patients had previously been treated with partial surgical removal (n = 6) and/or external radiation (n = 4) of their adenoma at least 1 yr before the study, whereas 4 patients had not been treated before somatostatin analog therapy. TSH, free T(4), and free T(3) levels were in the normal range during treatment with sc injections (n = 9) or continuous infusion (n = 2) of octreotide (280 +/- 25 microg/day). Mean thyroid hormone levels increased (P < 0.01) after the washout period (34 +/- 6 days). The patients received monthly im injections of 20 mg Octreotide-LAR. In patients with an elevated free T(4) level after 3 months (n = 1) the Octreotide-LAR dose was increased to 30 mg. After 3 months of Octreotide-LAR treatment, TSH, free T(4)/T(3), and alpha-subunit levels decreased, and 10 patients were euthyroid with normal free T(4) levels. These results remained at the same level over the next 3 months. There were no statistically significant differences in the TSH and free T(4) responses to sc octreotide or im Octreotide-LAR between previously untreated patients and patients who had undergone surgical resection and/or pituitary radiation before somatostatin analog treatment. During Octreotide-LAR treatment, minor digestive problems or moderate discomfort at the injection site, lasting less than 48 h, were reported in 6 and 5 patients, respectively. Gallbladder echographies did not reveal new gallstones during Octreotide-LAR treatment. In conclusion, this study shows that monthly im Octreotide-LAR is as effective as daily sc octreotide in controlling hyperthyroidism in patients with TSH-secreting pituitary adenomas, in both previously untreated patients and patients treated with surgery and/or pituitary radiotherapy. Octreotide-LAR is well tolerated, except for minor digestive problems or mild pain at the injection site. Therefore, Octreotide-LAR appears to be a useful therapeutic tool to facilitate medical treatment of TSH-secreting pituitary adenomas in patients who need long-term somatostatin analog therapy.

RESUMO

A clinician reflects on how nutrition and exercise assessments are integral to the care of patients with diabetes and, more broadly, how these assessments can increase understanding of the patient. Nutrition, metabolic control, self-esteem, and self-care are often intertwined. Using a team approach and acknowledging patient effort and attitude change can help patients modify lifestyle patterns, although the road to change may be slow. Exercise counseling should be part of nutrition recommendations. Poor nutritional habits represent a major challenge to improving health status and will require the coordinated efforts of health care providers and other stakeholders in society.

RESUMO

The incidence of Amanita mushroom poisoning seems to be increasing in the United States. Its neurological aspects contribute importantly to morbidity and mortality. In reported series, mortality has ranged from 50 to 90%, and survival following the appearance of coma was exceptional. The cause of nervous system involvement was uncertain. In the patient presented here, clinical and electroencephalographic observations were consistent with severe hepatic encephalopathy and correlated closely with liver function abnormalities. Despite the development of coma, full recovery followed the use of thioctic acid, an experimental therapeutic agent.
