Obesity in Latin American women and children.

National surveys conducted since 1982 were used to assess maternal and child obesity in Latin American and Caribbean countries and in U. S. residents of Mexican descent. Obesity in women, a body mass index (BMI) >/=30 kg/m2, was 3% in Haiti, 8-10% in eight Latin American countries and 29% in Mexican Americans. Median BMI for Latin American women were near or above the 50th percentile of the general U.S. population; values exceeded the 75th percentile in the case of Mexican Americans. The prevalence of overweight (>1 SD above mean weight-for-height) in children 1-5 y of age ranged from 6% in Haiti to 24% in Peru among 13 countries. Overweight occurred in 24% of Mexican-American children. Prevalences of overweight in children and of obesity in women were greater in urban areas and in households of higher socioeconomic status. Overweight in children increased with higher maternal education; however, in some countries, obesity in women decreased with higher education. No general pattern of change over time was observed in eight countries in overweight in children. Obesity in women increased in the three countries with such data and in Mexican-American women and children. There was a tendency for greater national incomes to be associated with greater obesity levels in women and with lower levels of stunting in children. Levels of obesity in the region indicate a public health concern, particularly among women, considering that studies have identified mortality and morbidity risks associated with obesity in adults.
Breath acetone is a reliable indicator of ketosis in adults consuming ketogenic meals.

BACKGROUND Ketogenic diets are used therapeutically to treat intractable seizures. Clinically, it appears that the maintenance of ketosis is crucial to the efficacy of the diet in ameliorating seizures. To understand how ketosis and seizure protection are related, a reliable, noninvasive measure of ketosis that can be performed frequently with minimal discomfort is needed. OBJECTIVE The objective was to determine which index, breath acetone or urinary acetoacetate, is more strongly related to the plasma ketones acetoacetate and beta-hydroxybutyrate. DESIGN After fasting overnight for 12 h, 12 healthy adults consumed 4 ketogenic meals over 12 h. Blood, breath, and urine samples were collected hourly. Blood was analyzed for plasma acetoacetate and beta-hydroxybutyrate, breath for acetone, and urine for acetoacetate. RESULTS By the end of the 12-h dietary treatment, plasma acetoacetate, plasma beta-hydroxybutyrate, and breath acetone had increased 3.5-fold, whereas urinary acetoacetate increased 13-fold when measured enzymatically and 25-fold when measured with urinary ketone dipsticks. Plasma acetoacetate was best predicted by breath acetone (R(2) = 0.70, P < 0.0001). Plasma beta-hydroxybutyrate was equally predicted by breath acetone and urinary acetoacetate (R(2) = 0.54, P = 0.0040). CONCLUSIONS Breath acetone is as good a predictor of ketosis as is urinary acetoacetate. Breath acetone analysis is noninvasive and can be performed frequently with minimal discomfort to patients. As an indicator of ketosis in epilepsy patients consuming a ketogenic diet, breath acetone may be useful for understanding the mechanism of the diet, elucidating the importance of ketosis in seizure protection, and ultimately, enhancing the efficacy of the diet by improving patient monitoring.
Captive chimpanzee (Pan troglodytes) behavior as a function of space per animal and enclosure type

Space per animal, or animal density, and enclosure type are important elements of functionally appropriate captive environments (FACEs) for chimpanzees. The National Institutes of Health (NIH) recommends that captive chimpanzees be maintained in areas of >250 ft2/animal. Several studies have investigated chimpanzee behavior in relation to space per animal, but only two studies have examined these variables while attempting to hold environmental complexity constant. Both have found few, if any, significant differences in behavior associated with increased space per animal. The NIH does not provide recommendations pertaining to enclosure type. Although Primadomes™ and corrals are considered acceptable FACE housing, no studies have investigated chimpanzee behavior in relation to these two common types of enclosures. We examined the NIH space per animal recommendation, and the effects of enclosure type, while maintaining similar levels of environmental complexity. We used focal animal observations to record the behavior of 22 chimpanzees in three social groups following within‐facility housing transfers. Chimpanzees that were moved from an area with space below the NIH recommendation to the same type of enclosure with space above the recommendation (dome to double dome) exhibited significantly more locomotion and behavioral diversity post‐transfer. Chimpanzees that were moved from an area with space below the recommendation to a different type of enclosure with space above the recommendation (dome to corral) exhibited significant increases in foraging and behavioral diversity, and a decrease in rough scratching. Lastly, chimpanzees that were moved from an area above the recommendation to a different enclosure type with space equal to the recommendation (corral to double dome) exhibited an increase in behavioral diversity. These results add to the body of literature that addresses the concept of specific minimum space requirements per chimpanzee, and highlight the need for more empirical investigation of the relationship between space per chimpanzee, behavior, and welfare.
Comparison of the tibia plateau angle between small and large dogs with cranial cruciate ligament disease

Summary Objectives: To compare the conformation of the proximal tibia evaluated on a medio- lateral radiograph between small and large dogs with cranial cruciate ligament disease (CCLD). Methods: Retrospective clinical study with dogs having radiographic evaluation and CCLD confirmed at surgery. The first group (n = 52) was comprised of dogs weighing less than 15 kg and the second group (n = 52) of dogs weighing more than 15 kg. The tibial plateau angle (TPA), the relative tibial tube-rosity width (rTTW), and the Z angle were measured on preoperative radiographs with imaging measurement software. Linear mixed models were used to assess the effect of weight, age, sex, and neutered status on radiographic measurements and to estimate interobserver variabilities. Results: The small dog group had a greater TPA (30.1° ± 5.3; p <0.001 with a mean difference of 4.9° [95% CI: 3.8–6.0]) and Z angle (69.9° ± 5.6; p<0.001 with a mean difference of 6.1° ([95% CI: 4.9–7.4]) than the large dog group. Sex and neutered status further influenced the TPA and Z angle val -ues. No significant effect was observed on the rTTW values. A strong correlation was found between the TPA and the Z angle (r = 0.61, p <0.001). Variances were not significantly different between observers. Overall the interobserver variability was low suggesting that agreement was good. Clinical significance: Small dogs with CCLD have a steeper tibial plateau than large dogs with CCLD. Sex and neutered status also had an effect on some measured variables. This anatomical difference could influence the surgical technique, which may affect the outcome. The good interobserver agreement suggests the observer is unlikely to influence surgical planning.
Determining bioavailability of food folates in a controlled intervention study.

BACKGROUND The concept of dietary folate equivalents (DFEs) in the United States recognizes the differences in bioavailability between natural food folates and the synthetic vitamin, folic acid. However, many published reports on folate bioavailability are problematic because of several confounding factors. OBJECTIVE We compared the bioavailability of food folates with that of folic acid under controlled conditions. To broadly represent the extent to which natural folates are conjugated in foods, we used 2 natural sources of folate, spinach (50% polyglutamyl folate) and yeast (100% polyglutamyl folate). DESIGN Ninety-six men were randomly assigned according to their screening plasma homocysteine (tHcy) concentration to 1 of 4 treatment groups for an intervention period of 30 d. Each subject received (daily under supervision) either a folate-depleted "carrier" meal or a drink plus 1) placebo tablet, 2) 200 microg folic acid in a tablet, 3) 200 microg natural folate provided as spinach, or 4) 200 microg natural folate provided as yeast. RESULTS Among the subjects who completed the intervention, responses (increase in serum folate, lowering of tHcy) relative to those in the placebo group (n = 18) were significant in the folic acid group (n = 18) but not in the yeast folate (n = 19) or the spinach folate (n = 18) groups. Both natural sources of folate were significantly less bioavailable than was folic acid. Overall estimations of folate bioavailability relative to that of folic acid were found to be between 30% (spinach) and 59% (yeast). CONCLUSION Relative bioavailability estimates were consistent with the estimates from the metabolic study that were used as a basis to derive the US DFE value.
6α-Acetoxyanopterine: A Novel Structure Class of Mitotic Inhibitor Disrupting Microtubule Dynamics in Prostate Cancer Cells

The lack of a cure for metastatic castrate-resistant prostate cancer (mCRPC) highlights the urgent need for more efficient drugs to fight this disease. Here, we report the mechanism of action of the natural product 6α-acetoxyanopterine (6-AA) in prostate cancer cells. At low nanomolar doses, this potent cytotoxic alkaloid from the Australian endemic tree Anopterus macleayanus induced a strong accumulation of LNCaP and PC-3 (prostate cancer) cells as well as HeLa (cervical cancer) cells in mitosis, severe mitotic spindle defects, and asymmetric cell divisions, ultimately leading to mitotic catastrophe accompanied by cell death through apoptosis. DNA microarray of 6-AA–treated LNCaP cells combined with pathway analysis identified very similar transcriptional changes when compared with the anticancer drug vinblastine, which included pathways involved in mitosis, microtubule spindle organization, and microtubule binding. Like vinblastine, 6-AA inhibited microtubule polymerization in a cell-free system and reduced cellular microtubule polymer mass. Yet, microtubule alterations that are associated with resistance to microtubule-destabilizing drugs like vinca alkaloids (vinblastine/vincristine) or 2-methoxyestradiol did not confer resistance to 6-AA, suggesting a different mechanism of microtubule interaction. 6-AA is a first-in-class microtubule inhibitor that features the unique anopterine scaffold. This study provides a strong rationale to further develop this novel structure class of microtubule inhibitor for the treatment of malignant disease. Mol Cancer Ther; 16(1); 3–15. ©2016 AACR.
TFOS DEWS II iatrogenic report Jos e

Dry eye can be caused by a variety of iatrogenic interventions. The increasing number of patients looking for eye care or cosmetic procedures involving the eyes, together with a better understanding of the pathophysiological mechanisms of dry eye disease (DED), have led to the need of a specific report about iatrogenic dry eye within the TFOS DEWS II. Topical medications can cause DED due to their allergic, toxic and immuno-inflammatory effects on the ocular surface. Preservatives, such as benzalkonium chloride, may further aggravate DED. A variety of systemic drugs can also induce DED secondary to multiple mechanisms. Moreover, the use of contact lens induces or is associated with DED. However, one of the most emblematic situations is DED caused by surgical procedures such as corneal refractive surgery as in laser-assisted in situ keratomileusis (LASIK) and keratoplasty due to mechanisms intrinsic to the procedure (i.e. corneal nerve cutting) or even by the use of postoperative topical drugs. Cataract surgery, lid surgeries, botulinum toxin application and cosmetic procedures are also considered risk factors to iatrogenic DED, which can cause patients' dissatisfaction, visual disturbances and poor surgical outcomes. This report also presents future directions to address iatrogenic DED, including the need of deeper epidemiological studies about the risk factors, development of less toxic medications and preservatives, as well as new techniques for less invasive eye surgeries. Novel research into detection of early dry eye prior to surgeries, efforts to establish appropriate therapeutics and a greater attempt to regulate and oversee medications, preservatives and procedures should be considered. © 2017 Elsevier Inc.

Association between urinary potassium, urinary sodium, current diet, and bone density in prepubertal children.

BACKGROUND Our understanding of the role of nutrients in bone development in children is limited. OBJECTIVE We examined the associations between urinary potassium, urinary sodium, usual dietary intake, and bone mineral density (BMD) in prepubertal children. DESIGN This was a cross-sectional study of 330 boys and girls aged 8 y. Urinary measures were assessed in a single, timed, overnight urine specimen. Usual diet was assessed with a food-frequency questionnaire completed by a parent or guardian. BMD at the femoral neck, lumbar spine, and total body was measured by dual-energy X-ray absorptiometry. RESULTS Urinary potassium correlated significantly with BMD at all sites (femoral neck: r = 0.20, P < 0.001; lumbar spine: r = 0.19, P = 0.001; total body: r = 0.24, P < 0.001). After adjustment for confounders (primarily lean body mass), this association was lower in magnitude but remained significant at 2 sites with a consistent trend at the third (femoral neck: P = 0.15; lumbar spine: P = 0.046; total body: P = 0.028). Urinary sodium was not associated with BMD at any site. No nutrient or food intake estimate was associated with BMD, although urinary potassium correlated significantly with potassium intake (r = 0.14, P = 0.016) and fruit and vegetable intake (r = 0.12, P = 0.033). CONCLUSIONS Urinary potassium was associated with both dietary intake and BMD independent of lean body mass in these well-nourished, calcium-replete young children. These findings should be confirmed in further longitudinal studies. Nevertheless, this association is likely to represent dietary intake of potassium and suggests that measurement of urinary potassium is superior to food-frequency questionnaires for assessing potassium intake in this age group.
The capacity of nondigestible carbohydrates to stimulate fecal bifidobacteria in healthy humans: a double-blind, randomized, placebo-controlled, parallel-group, dose-response relation study.

BACKGROUND Nondigestible carbohydrates (NDCHs) are fermented in the colon, where they can selectively promote the growth of bifidobacteria. OBJECTIVE Our aim was to determine the bifidogenic potential of different NDCHs used in human diets. DESIGN Two hundred healthy volunteers participated in this double-blind study. During phase 1 (screening), 64 volunteers were randomly assigned to 8 groups of 8 subjects each; for 7 d, they ingested 10 g/d of 1 of the 7 NDCHs tested or of the placebo. During phase 2 (dose-response study), 136 volunteers were randomly assigned to 4 groups of 32 subjects who received 2.5, 5.0, 7.5, or 10 g/d, respectively (8 subjects/dose), of one of the NDCHs that were proven to be bifidogenic during phase 1 and a fifth group of 8 subjects (control subjects) who received the placebo. Stools were recovered before and after NDCH consumption. RESULTS In phase 1, 4 NDCHs were found to be bifidogenic: short-chain fructooligosaccharides (P=0.008), soybean oligosaccharides (P=0.006), galactooligosaccharides (P <0.0001), and type III resistant starch (P=0.02); lactulose, long-chain inulin, and isomaltooligosaccharides were not bifidogenic. In phase 2, the effects of 7-d treatment on bifidobacteria concentrations were found to differ significantly among the 4 NDCHs (P=0.009 for time x treatment interaction). However, no significant differences were found among doses, and there was no significant dose x time interaction. A low baseline bifidobacteria count was significantly associated with the bifidogenic response to treatment (P <0.001). CONCLUSION This study showed the different bifidogenic properties among the substrates and underlined the importance of taking into account the baseline bifidobacteria counts when evaluating the effect of the treatment.
Vegetable-borne lutein, lycopene, and beta-carotene compete for incorporation into chylomicrons, with no adverse effect on the medium-term (3-wk) plasma status of carotenoids in humans.

BACKGROUND The results of epidemiologic studies have consistently shown associations between dietary intake or plasma carotenoid status and incidence of cancers and cardiovascular and eye diseases. OBJECTIVE The aim was to assess whether vegetable-borne carotenoids (lycopene, lutein, and beta-carotene) compete for intestinal absorption and whether this affects the plasma status of carotenoids in the medium term (ie, after 3 wk). DESIGN During 3-wk periods separated by 3-wk washout periods, 20 women were supplemented with either 96 g tomato purée/d (14.98 mg lycopene + 1.50 mg beta-carotene), 92 g cooked chopped spinach/d (11.93 mg lutein + 7.96 mg beta-carotene), 96 g tomato purée/d + 92 g chopped spinach/d, 96 g tomato purée/d + 2 lutein pills (12 mg lutein), or 92 g chopped spinach/d + 1 lycopene pill (15 mg lycopene). Plasma carotenoids were measured before and after each supplementation period. The subjects also participated in postprandial experiments in which they ingested meals containing double amounts of the supplements described above. Carotenoids were measured in chylomicrons to assess the interaction of carotenoids on absorption. RESULTS Adding a second carotenoid to a meal that provided a first carotenoid diminished the chylomicron response to the first carotenoid. However, cosupplementation with a second carotenoid of a diet supplemented with a first carotenoid did not diminish the medium-term plasma response to the first carotenoid. CONCLUSION Consumption of carotenoids from different vegetable sources does not diminish plasma carotenoid concentrations in the medium term, despite the finding in postprandial testing of competitive inhibitory interactions among different carotenoids.
Plasma vitamin B-12 concentrations in an elderly latino population are predicted by serum gastrin concentrations and crystalline vitamin B-12 intake.

The prevalence of vitamin B-12 deficiency increases with age, probably resulting from malabsorption of food-bound B-12 secondary to gastric atrophy. On the basis of this assumption, the Institute of Medicine (IOM) recommends those aged >50 y consume crystalline vitamin B-12. There is limited information on the prevalence of gastric atrophy in the elderly and whether the IOM recommendation would be effective. The objective of this study was to assess predictors of vitamin B-12 status and their interactions in free-living elderly. Individuals (n = 57) with deficient plasma vitamin B-12 (p-B12 < 148 pmol/L) were compared with 68 individuals with marginal p-B12 (148-221 pmol/L) and 52 with normal p-B12 (>221 pmol/L) in a cross-sectional sample (n = 1546) of elderly (>60 y) Latinos in California. Associations were examined among p-B12 and serum gastrin, vitamin B-12 intake from food and crystalline sources, and medications that putatively affect vitamin B-12 absorption. Serum gastrin was elevated, indicating gastric atrophy, in 48% of participants with deficient p-B12, 23% with marginal p-B12 and 21% of normal p-B12 participants, and was a significant predictor of deficient p-B12 and high plasma homocysteine (p-tHcy). Median total vitamin B-12 intake exceeded recommendations and was similar among status groups. Crystalline vitamin B-12 intake in the normal p-B12 group was higher than in the deficient p-B12 group (P < 0.01), and tended to be higher than the marginal group (P = 0.07). When serum gastrin was elevated, p-B12 was predicted by crystalline vitamin B-12, but not by intake of vitamin B-12 from food. Elevated serum gastrin was highly prevalent and predicted vitamin B-12 depletion. Crystalline vitamin B-12 intake predicted p-B12 in individuals with elevated serum gastrin, supporting IOM recommendations to increase consumption of crystalline vitamin B-12.
Digging for Non-Dominant Mobility Patterns

In this paper we investigate non-dominant collective urban mobility patterns in user-generated mobile network traffic data using a visual analytics tool. Based on our previous approach and results, we herein focus on the next level of mobility detail: we visually dig deeper and disclose some nondominant, potentially hidden mobility patterns in four urban test areas in Northern Italy. The results reveal interesting insights into the cities’ functional structure in terms of human mobility, for instance mobility hotspots and mobility gateways.

Assessment of prescribed medications and pattern of distribution for potential drug–drug interactions among chronic kidney disease patients attending the Nephrology Clinic of Lagos University Teaching Hospital in Sub-Saharan West Africa

Introduction Life expectancy has increased significantly among chronic kidney disease (CKD) patients due to the extensive use of polypharmacy practice for medication prescriptions. This predisposes them to potential drug–drug interactions (DDIs), which can lead to an increase in morbidity, mortality, length of hospital stay, and health care cost. Methods This was a 30-month retrospective study that reviewed the medical case records of consenting adult CKD patients from January 2014 to June 2016. The Medscape drug reference database was used to evaluate patients’ medications for potential DDIs. Results This study involved 123 adult CKD patients (63 [51.22%] males and 60 [48.78%] females) with a mean age of 53.81±16.03 years. The most common comorbid conditions were hypertension (112 [91.10%]) and diabetes mellitus (45 [36.60%]). Regarding the form of nephrological interventions being offered, the majority of the respondents - 66 (53.66%) were on maintenance dialysis, followed by 53 (43.09%) respondents on conservative care, while 4 (3.25%) respondents were on renal transplantation. A total of 1264 prescriptions were made, and the mean number of prescribed medications per patient was 10.28±3.85. The most frequently prescribed medications were furosemide (88 [71.6%]), heparin (67 [54.47%]), lisinopril (65 [52.9%]), oral calcium carbonate (CaCO3) (63 [51.2%]), α-calcidol (62 [50.4%]), and erythropoietin (61 [49.6%]). A total number of 1851 potential DDIs were observed among 118 patients. The prevalence of potential DDIs in this study was 78.0%, while the mean DDI per prescription was 1.50. Among the potential DDIs observed, the severity was mild in 639 (34.5%) patients, moderate in 1160 (62.7%) patients, and major in 51 (2.8%) patients and only 1 (0.1%) patient was of contraindicated drug combination. The most frequent DDIs’ pattern observed was between oral CaCO3 and oral ferrous sulfate. There was a statistically significant association between the number of prescribed medications and the estimated glomerular filtration rate (eGFR; pre-ESRD and ESRD staging) with a P-value of 0.00000119. This implies that the number of prescribed medications increases as the eGFR declines in advance CKD stage patients. Conclusion Most of these interactions have moderate severity and delayed onset, hence the need to follow-up these patients after prescription in order to reduce associated morbidity, mortality, length of hospital stay, and health care cost. Physicians and clinical pharmacists should utilise available interaction software to avoid harmful DDIs in these patients.
