ABSTRACT
BACKGROUND: Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) are serious health challenges. Point prevalence surveys (PPSs) are valuable tools for monitoring HAIs and AMR. AIM: To describe results of the ECDC PPS 2022 dealing with the prevalence of HAIs, antimicrobial consumption, and associated factors, in acute care hospitals. METHODS: The survey was performed in November 2022 in 14 hospitals according to the protocol proposed by the European Centre for Disease Prevention and Control. Multilevel logistic regression was performed using geographical area/hospital type as cluster variable to evaluate the factors independently associated with HAIs and antibiotics. FINDINGS: The point prevalence of HAIs was 7.43%. Patients hospitalized for longer periods were more likely to have an HAI as well as those aged 15-44 years, with a rapidly fatal disease, intubated, and with one or two devices. Antibiotics prevalence was 47.30%. Males, unknown McCabe scores, minimally invasive/non-National Healthcare Safety Network (NHSN) surgery, patients with HAIs, hospitals with a higher alcohol hand-rub consumption, hospitals with a greater number of IPC personnel, geriatric wards, and hospitals with 300-600 beds were more likely to be under antimicrobial therapy. CONCLUSION: This PPS provided valuable information on the prevalence of HAIs and antimicrobial consumption and variables associated. The high prevalence of HAIs highlights the need for improved infection control measures.

CONTEXT: Abnormalities in the hypothalamic-pituitary-adrenal (HPA) axis are frequent accompaniments of depression, and studies have documented the role of stress and stressful life events in the ontogeny of perimenopausal depressions (PMD). Because HPA axis function in women is further modulated both by aging and ovarian steroids, it is possible that a dysregulated HPA axis contributes to the increased risk of PMD. OBJECTIVE: We examined HPA axis function in perimenopausal women with and without depression using the combined dexamethasone-corticotropin-releasing hormone (Dex/CRH) test. METHODS: Dex/CRH tests were performed on 20 women with PMD and 20 women who were also perimenopausal but without current or past depression (control women). Main outcome measures were plasma levels of cortisol and adrenocorticotropin (ACTH) and 24-hour urinary free cortisol (UFC). Five women took chronic stable medications, otherwise all women were medically healthy, and both groups were comparable with respect to reproductive stage and age. Standardized symptom rating scales were administered to each woman prior to Dex/CRH testing. RESULTS: No group differences were present in either baseline or stimulated ACTH and cortisol secretion. Baseline plasma measures of estradiol, progesterone, and 24-hour UFC levels similarly did not differ in PMD and control women. CONCLUSION: Despite reports of increased stress responsiveness in PMD, we observed no abnormalities of HPA axis activity associated with PMD compared with women without depression. These findings suggest that PMD is not uniformly associated with HPA dysregulation and could reflect underlying pathophysiologic processes that are distinct from women with nonreproductive-related depressions.

OBJECTIVE: We examined the short-term efficacies of three estrogen-like compounds under placebo-controlled conditions in women with perimenopause-related depression (PMD). METHODS: Women with PMD were randomized in a double-blind parallel design to one of four treatments: transdermal 17-beta estradiol (TE) (100 mcg/d); oral raloxifene (60âmg/d); a proprietary phytoestrogen compound, Rimostil (1,000âmg twice/d); or placebo for 8 weeks. The main outcome measures were the Center for Epidemiology Studies Depression Scale, 17-item Hamilton Rating Scale for Depression (HRSD), and the Beck Depression Inventory completed at each clinic visit. Secondary outcomes included a visual analogue self-rating completed at each clinic visit, and daily self-ratings of hot flush severity. Cognitive tests were performed at pretreatment baseline and at the end of the trial. In the primary analysis, we obtained four repeated measures in each woman in the four treatment arms. Analyses were done with SAS Version 9.4 software (SAS Institute, Inc, Cary, NC), using PROC MIXED (for mixed models). All models included the following four explanatory variables, regardless of whether they were statistically significant: 1) treatment group (TE, raloxifene, Rimostil, placebo); 2) week (W2, W4, W6, W8); 3) treatment group-by-week interaction; and 4) baseline value of the measure being analyzed. The inclusion of additional variables was evaluated individually for each outcome measure. RESULTS: Sixty-six women were randomized into the trial, four women dropped out of the trial, and 62 women were included in the final data analysis. No effect of treatment group was observed in either the Center for Epidemiology Studies Depression Scale (Pâ=â0.34) or Beck Depression Inventory (Pâ=â0.27) scores; however, there was a difference in HRSD scores between treatment groups (Pâ=â0.0037) that pair-wise comparisons of the combined weekly scores in each treatment demonstrated TE's beneficial effects on HRSD scores compared with Rimostil (Pâ=â0.0005), and less consistently with placebo (Pâ=â0.099). The average (SD) of the baseline scores for each treatment group on the HRSD was as follows: TE-15.3 (4.5), raloxifene-16.0 (3.7), Rimostil-14.0 (2.7), and placebo-15.2 (3.0). Whereas the HRSD scores after 8 weeks of treatment (least-square means) were TE-5.2(1.1), raloxifene-5.8(1.2), Rimostil-11.2(1.4), and placebo-7.8(1.1). No differences were observed between raloxifene and either TE or placebo in any scale score. HRSD scores in women assigned to TE were improved compared with those on Rimostil during weeks 6 and 8 (P valuesâ=â0.0008, 0.0011, respectively). Cognitive testing at week 8 showed that none of the three active treatment groups performed better than placebo. CONCLUSIONS: This study did not identify significant therapeutic benefits of TE, Rimostil, or raloxifene compared with placebo in PMD. However, improvements in depression ratings were observed between TE compared with Rimostil. Thus, our findings do not support the role of ERbeta compounds in the treatment of PMD (and indeed could suggest a more important role of ERalpha).

PURPOSE: Roflumilast (Daliresp, Daxas) is a FDA-approved phosphodiesterase 4 (PDE4) inhibitor for the treatment of moderate-to-severe chronic obstructive pulmonary disease. In mice and in limited human studies, this oral medication can cause weight loss and improve insulin sensitivity. We set out to determine the mechanism of its effect on insulin sensitivity. PATIENTS AND METHODS: Eight adults with overweight/obesity and prediabetes received roflumilast for 6 weeks. Before and after roflumilast, subjects underwent tests of insulin sensitivity, mixed meal test, body composition, markers of inflammation, and mitochondria function. Dietary intake and physical activity were also assessed. Our primary outcome was the change in peripheral insulin sensitivity, as assessed by the hyper-insulinemic euglycemic clamp. RESULTS: This study was underpowered for the primary outcome. Pre- and post-roflumilast mean peripheral insulin sensitivity were 48.7 and 70.0 mg/g fat free mass/minute, respectively, (P-value=0.18), respectively. Among the mixed meal variables, roflumilast altered glucagon-like peptide 1 (GLP-1) hormone the most, although the average effect was not statistically significant (P=0.18). Roflumilast induced a trend toward significance in 1) decreased energy intake (from 11,095 KJ to 8,4555 KJ, P=0.07), 2) decreased fat mass (from 34.53 to 32.97 kg, P=0.06), 3) decreased total and LDL cholesterol (P=0.06 for both variables), and 4) increased plasma free fatty acids (from 0.40 to 0.50 mEq/L, P=0.09) The interval changes in adiposity and free fatty acid were significantly associated with the subject's age (P-value range= <0.001 to 0.02 for the correlations). Inflammatory and adhesion markers, though unchanged, significantly correlated with one another and with incretin hormones only after roflumilast. CONCLUSION: We demonstrate, for the first time in humans, increasing percentage of fat mass loss from roflumilast with increasing age in adults with prediabetes and overweight/obesity. We also demonstrate novel associations among roflumilast-induced changes in incretin hormones, inflammatory markers, peripheral insulin sensitivity, and adiposity. We conclude that roflumilast's early effects on insulin sensitivity is indirect and likely mediated through roflumilast's prioritization of lipid over glucose handling.

ABSTRACT
Thioacetates as precursors of thiols are interesting starting points for synthesizing other organosulfur compounds. Herein, we propose a simple, efficient and fast method to obtain organic thioacetates using water as a solvent. Taking into account the great attention that has been paid toward environmentally friendly synthetic procedures in the past decades, we prove the role and the strength of the thioacetate anion as a nucleophile for nucleophilic displacement reactions in an aqueous medium. The reactions were carried out under pH control, to prevent the decomposition of the mesylate starting materials, using potassium carbonate as a safe and mild base. A simple work up allows products to be obtained with excellent yield and acceptable purity.
ABSTRACT
BACKGROUND: The aims of this study were to compare the diagnostic accuracy of blood smear review criteria, by means of three different panel rules, those proposed by: the International Consensus Group for Hematology [41-ICGH rules], the Italian Survey [IS rules] and the Working Group on Hematology-SIBioC (WGH) consensus rules (WGH rules). METHODS: This study is based on 2707 peripheral blood (PB) samples referred for routine hematological testing to the WGH-associated laboratories displaced all over the Italian territory. The PB samples were processed on seven different hematology analyzers (HAs): Advia 2120i, XE-2100, BC-6800, ABX Pentra, XN-1000, Cell-DYN Sapphire, and DxH800, respectively. All the results provided by the HAs were analyzed through the application of three different blood smear review criteria: that is, the 41-ICGH, IS, and WGH rules. Finally, data were compared with those obtained by optical microscopy (OM), as the current gold standard. RESULTS: The overall the agreement OM classification with ICGH, IS, and WGH panel rules is 0.83, 0.83, and 0.85, respectively. The false negatives are 2.1%, 3.0%, and 2.9%, while false positives are 15.1%, 13.7%, and 11.7%, respectively. All the seven HAs showed variable interinstrument performance, as three different criteria for OM review were adopted on each of them from time to time. CONCLUSION: These results presented show that the customization of validation rules is necessary for enhancing the quality of hematological testing and optimizing workflow.

INTRODUCTION: Recent automated hematology analyzers (HAs) can identify and report nucleated red blood cells (NRBC) count as a separate population out of white blood cells (WBC). The aim of this study was to investigate the analytical performances of NRBC enumeration on five top of the range HAs. METHODS: We evaluated the within-run and between-day precision, limit of blank (LoB), limit of detection (LoD), and limit of quantitation (LoQ) of XE-2100 and XN-module (Sysmex), ADVIA 2120i (Siemens), BC-6800 (Mindray), and UniCel DxH 800 (Beckman Coulter). Automated NRBC counts were also compared with optical microscopy (OM). RESULTS: The limits of detection for NRBC of the BC-6800, XN-module, XE-2100, UniCel DxH 800, and ADVIA 2120i are 0.035×109 /L, 0.019×109 /L, 0.067×109 /L, 0.038×109 /L, and 0.167×109 /L, respectively. Our data indicated excellent performance in terms of precision. The agreement with OM was excellent for BC-6800, XN-module, and XE-2100 (Bias 0.023, 0.019, and 0.033×109 /L, respectively). ADVIA 2120i displayed a significant constant error and UniCel DxH 800 both proportional and small constant error. CONCLUSION: Regards to NRBC counting, the performances shown by BC-6800, XN-module, and XE-2100 are excellent also a low count, ADVIA 2120i and UniCel DxH 800 need to be improved.

The objective of this investigation was to analyze the effectiveness of a quality improvement initiative in limiting the spread of multidrug-resistant organisms (MDROs) in the hospital setting. During the period 2011-2013, a multimodal intervention was activated at a tertiary care center in Italy. The intervention included: laboratory-based surveillance, interdisciplinary training sessions, monitoring the adoption of isolation precautions and daily supervision provided by infection control nurses, and a monthly feedback. Time series analysis was used to evaluate the trends and correlations between the MDROs rate, intensity of checking rounds, and hospital-wide data (i.e., transfer of patients, patients' days, site of isolation, etc.). A total of 149,251 patients were included in the study. The proportion of patients undergoing transmission-based isolation precautions within 24 h from a positive laboratory finding increased from 83% in 2011 to 99% in 2013 (p < 0.05). The wards appropriately adopting the correct isolation precaution increased from 83% in 2011 to 97.6% in 2013 (p < 0.05). The frequency of controls was significantly reduced after the observation of compliance in the appropriate wards (p < 0.05). After three years, the incidence rate changed from 5.8/1000 days of stay [95% confidence interval (CI) 5.6-6.1] in 2011 to 4.7 (95% CI 4.4-4.9) in 2013 (p < 0.0001). Moreover, microorganisms isolated from different types of specimens showed variable potential for transmission (i.e., skin as the most potential and urine the least). The results demonstrate the efficacy of the multimodal intervention, with sustained reduction of MDROs rate, besides check reduction, and highlight the long-term efficacy of checking rounds in changing professionals' behaviors.

The impact of depression on quality of life (QOL) and social support has neither been well characterized in clinical samples of women with perimenopausal depression (PMD) nor have the relative contributions of depression and other menopausal symptoms (e.g., hot flushes) to declining QOL been clarified. In this study, we compared QOL measures, social support, and functional disability in PMD and non-depressed perimenopausal women. We evaluated women aged 40-60 years who presented with menstrual cycle irregularity, elevated plasma FSH levels, and met criteria for perimenopause. A structured clinical interview was administered to determine the presence or absence of major and minor depression. Outcome measures included the Quality of Life Enjoyment Scale Questionnaire, the Sheehan Disability Scale, the Global Assessment of Functioning, the Social Adjustment Scale, and the Duke Social Support Index. Kruskal-Wallis tests and ANOVAs were used to compare outcome measures. Ninety women with PMD and 51 control women participated in this study. Women with PMD reported significantly decreased QOL, social support, and adjustment and increased disability compared with non-depressed perimenopausal women. Neither perimenopausal reproductive status alone nor the presence of hot flushes had a significant negative impact on QOL measures. PMD is accompanied by significant reductions in QOL, social support, and disability similar to depression in women at other stages of life. PMD may also contribute to decreased QOL in community- or clinic-based samples of perimenopausal women. It remains unclear whether the clinical characteristics we identified reflect pre-existing risk factors for depression during the perimenopause or the effects of a current depression. Future clinical and treatment studies in perimenopausal women should distinguish depressed women when outcome measures include QOL.

To compare impact of incident diabetes on atherosclerotic cardiovascular disease (ASCVD) risk among postmenopausal women according to statin use. Prospective data from 120,499 postmenopausal women without prevalent diabetes or cardiovascular disease at baseline from the Women's Health Initiative were used. Incident diabetes was self-reported annually and defined as treatment with pills or injectable medication for diabetes. Current statin use was determined at enrollment and years 1, 3, 6, 9 and 13.5 in the three clinical trial arms, and at baseline, year 3, and 13.5 for the observational study. The primary outcome was incident ASCVD events, self-reported annually and adjudicated by blinded local and central physicians. Incident diabetes and statin use status were fitted as time-varying covariates in Cox regression models to assess ASCVD risk during an average follow-up of 13.6 years. For those not on statins at the time of diabetes diagnosis, there was a 42 % increased risk of ASCVD [hazard ratio (HR) 1.42, 95 % CI 1.28-1.58] among women with incident diabetes versus those without diabetes. Among women on statins, there was a 39 % increased risk of ASCVD (HR 1.39, 95 % CI 1.12-1.74) in women with incident diabetes versus those without diabetes. The increased ASCVD risk due to diabetes was similar between women before or after initiating statins (P = 0.89). Whether diabetes was diagnosed before or after statin use did not alter the increased risk of ASCVD associated with diabetes. Mitigating the increased incidence of diabetes in statin users could increase the ASCVD benefit-to-risk ratio of statins.

BACKGROUND: Despite well-established sex differences in the performance on tests of several cognitive domains (e.g., visuospatial ability), few studies in humans have evaluated if these sex differences are evident both in the presence of circulating sex hormones and during sex steroid hormonal suppression. Sex differences identified in the relative absence of circulating levels of estradiol and testosterone suggest that differences in brain structure or function exist independent of current hormonal environment and are more likely a reflection of differing developmental exposures and/or genetic substrates. OBJECTIVE: To evaluate cognitive performance in healthy eugonadal men and women before and again during GnRH agonist-induced hypogonadism. METHODS: Men (n=16) and women (n=15) without medical or psychiatric illness were matched for IQ. Cognitive tests were performed at baseline (when eugonadal) and after 6-8 weeks of GnRH agonist-induced gonadal suppression. The test batteries included measures of verbal and spatial memory, spatial ability, verbal fluency, motor speed/dexterity, and attention/concentration. Data were analyzed using repeated-measures models. RESULTS: During both eugonadism and hypogonadism, men performed significantly better than women on several measures of visuospatial performance including mental rotation, line orientation, Money Road Map, Porteus maze, and complex figure drawing. Although some test performances showed an effect of hormone treatment, the majority of these differences reflected an improved performance during hypogonadism compared with baseline (and probably reflected practice effects). CONCLUSION: The well-documented male advantage in visuospatial performance, which we observed during eugonadal conditions, was maintained in the context of short-term suppression of gonadal function in both men and women. These findings suggest that, in humans, sex differences in visuospatial performance are not merely dependent on differences in the current circulating sex steroid environment. Thus sex differences in visuospatial performance in adulthood could reflect early developmental effects of sex steroid exposure or other environmental exposures differing across the sexes as our data confirm that these differences are independent of circulating estradiol or testosterone levels in men and women.

IMPORTANCE: Perimenopause is accompanied by an increased risk of new and recurrent depression. The coincidence of declining ovarian function with the onset of depression led to the inference that "withdrawal" from physiologic estradiol levels underpinned depression in perimenopause. To our knowledge, this is the first controlled systematic study to directly test the estrogen withdrawal theory of perimenopausal depression (PMD). OBJECTIVE: To examine the role of estradiol withdrawal in PMD. DESIGN, SETTING, AND PARTICIPANTS: Initial open-label treatment with estradiol followed by randomized, double-blind, placebo-controlled, parallel-design evaluation of continued estradiol treatment was evaluated at an outpatient research facility at the National Institutes of Health Clinical Center. An intent-to-treat analysis was performed between October 2003 and July 2012. Participants included asymptomatic postmenopausal women with past PMD responsive to hormone therapy (n = 26) and asymptomatic postmenopausal women with no history of depression (n = 30) matched for age, body mass index, and reproductive status who served as controls. Data were analyzed between November 2012 and October 2013 by repeated-measures analysis of variance. INTERVENTIONS: After 3 weeks of open-label administration of transdermal estradiol (100 µg/d), participants were randomized to a parallel design to receive either estradiol (100 µg/d; 27 participants) or matched placebo skin patches (29 participants) for 3 additional weeks under double-blind conditions. MAIN OUTCOMES AND MEASURES: Center for Epidemiologic Studies-Depression Scale and 17-item Hamilton Depression Rating Scale (completed by raters blind to diagnosis and randomization status), self-administered visual analog symptom ratings, and blood hormone levels obtained at weekly clinic visits. RESULTS: None of the women reported depressive symptoms during open-label use of estradiol. Women with past PMD who were crossed over from estradiol to placebo experienced a significant increase in depression symptom severity demonstrated using the Center for Epidemiologic Studies-Depression Scale and 17-item Hamilton Depression Rating Scale, with mean (SD) scores increasing from estradiol (ie, 2.4 [2.0] and 3.0 [2.5]) to placebo (8.8 [4.9] and 6.6 [4.5], respectively [P = .0004 for both]). Women with past PMD who continued estradiol therapy and all women in the control group remained asymptomatic. Women in both groups had similar hot-flush severity and plasma estradiol levels during use of placebo. CONCLUSIONS AND RELEVANCE: In women with past PMD that was previously responsive to hormone therapy, the recurrence of depressive symptoms during blinded hormone withdrawal suggests that normal changes in ovarian estradiol secretion can trigger an abnormal behavioral state in these susceptible women. Women with a history of PMD should be alert to the risk of recurrent depression when discontinuing hormone therapy. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00060736.

BACKGROUND: Few studies have compared diets to determine whether a program focused on 1 dietary change results in collateral effects on other untargeted healthy diet components. OBJECTIVE: To evaluate a diet focused on increased fiber consumption versus the multicomponent American Heart Association (AHA) dietary guidelines. DESIGN: Randomized, controlled trial from June 2009 to January 2014. (ClinicalTrials.gov: NCT00911885). SETTING: Worcester, Massachusetts. PARTICIPANTS: 240 adults with the metabolic syndrome. INTERVENTION: Participants engaged in individual and group sessions. MEASUREMENTS: Primary outcome was weight change at 12 months. RESULTS: At 12 months, mean change in weight was -2.1 kg (95% CI, -2.9 to -1.3 kg) in the high-fiber diet group versus -2.7 kg (CI, -3.5 to -2.0 kg) in the AHA diet group. The mean between-group difference was 0.6 kg (CI, -0.5 to 1.7 kg). During the trial, 12 (9.9%) and 15 (12.6%) participants dropped out of the high-fiber and AHA diet groups, respectively (P = 0.55). Eight participants developed diabetes (hemoglobin A1c level ≥6.5%) during the trial: 7 in the high-fiber diet group and 1 in the AHA diet group (P = 0.066). LIMITATIONS: Generalizability is unknown. Maintenance of weight loss after cessation of group sessions at 12 months was not assessed. Definitive conclusions cannot be made about dietary equivalence because the study was powered for superiority. CONCLUSION: The more complex AHA diet may result in up to 1.7 kg more weight loss; however, a simplified approach to weight reduction emphasizing only increased fiber intake may be a reasonable alternative for persons with difficulty adhering to more complicated diet regimens.

BACKGROUND: The Anti-Inflammatory Diet (IBD-AID) is a nutritional regimen for inflammatory bowel disease (IBD) that restricts the intake of certain carbohydrates, includes the ingestion of pre- and probiotic foods, and modifies dietary fatty acids to demonstrate the potential of an adjunct dietary therapy for the treatment of IBD. METHODS: Forty patients with IBD were consecutively offered the IBD-AID to help treat their disease, and were retrospectively reviewed. Medical records of 11 of those patients underwent further review to determine changes in the Harvey Bradshaw Index (HBI) or Modified Truelove and Witts Severity Index (MTLWSI), before and after the diet. RESULTS: Of the 40 patients with IBD, 13 patients chose not to attempt the diet (33%). Twenty-four patients had either a good or very good response after reaching compliance (60%), and 3 patients' results were mixed (7%). Of those 11 adult patients who underwent further medical record review, 8 with CD, and 3 with UC, the age range was 19-70 years, and they followed the diet for 4 or more weeks. After following the IBD-AID, all (100%) patients were able to discontinue at least one of their prior IBD medications, and all patients had symptom reduction including bowel frequency. The mean baseline HBI was 11 (range 1-20), and the mean follow-up score was 1.5 (range 0-3). The mean baseline MTLWSI was 7 (range 6-8), and the mean follow-up score was 0. The average decrease in the HBI was 9.5 and the average decrease in the MTLWSI was 7. CONCLUSION: This case series indicates potential for the IBD-AID as an adjunct dietary therapy for the treatment of IBD. A randomized clinical trial is warranted.

OBJECTIVE: Women with primary ovarian insufficiency (POI) display low androgen levels, which could contribute to mood and behavioral symptoms observed in this condition. We examined the effects of physiologic testosterone therapy added to standard estrogen/progestin therapy on quality of life, self-esteem, and mood in women with POI. METHODS: One hundred twenty-eight women with 46,XX spontaneous POI participated in a 12-month randomized, placebo-controlled, parallel-design investigation of the efficacy of testosterone augmentation of estrogen/progestin therapy. Quality of life, self-esteem, and mood symptoms were evaluated with standardized rating scales and a structured clinical interview. Differences in outcome measures between the testosterone and placebo treatments were analyzed by Wilcoxon rank sum tests. RESULTS: No differences in baseline characteristics, including serum hormone levels (P > 0.05), were found. Baseline mean (SD) Center for Epidemiologic Studies Depression Scale scores were 10.7 (8.6) and 9.2 (7.8) for testosterone and placebo, respectively (P = 0.35). After 12 months of treatment, measures of quality of life, self-esteem, and mood symptoms did not differ between treatment groups. Serum testosterone levels achieved physiologic levels in the testosterone group and were significantly higher compared with placebo (P < 0.001). Baseline testosterone levels were not associated with either adverse or beneficial clinical effects. CONCLUSIONS: A 150-µg testosterone patch achieves physiologic hormone levels in women with POI. Our findings suggest that augmentation of standard estrogen/progestin therapy with physiologic testosterone therapy in young women with POI neither aggravates nor improves baseline reports of quality of life or self-esteem and had minimal effects on mood. Other mechanisms might play a role in the altered mood accompanying this disorder.

BACKGROUND: Dietary guidelines suggest limiting daily sodium intake to <2,300 mg for the general population, and <1,500 mg/d for those with certain cardiovascular risk factors. Despite these recommendations, few Americans are able to achieve this goal. Identifying challenges in meeting these guidelines is integral for successful compliance. This analysis examined patterns and amount of daily sodium intake among participants with metabolic syndrome enrolled in a one-year dietary intervention study. METHODS: Two hundred forty participants with metabolic syndrome enrolled in a dietary intervention trial to lose weight and improve dietary quality. Three 24-hour dietary recalls were collected at each visit which provided meal patterns and nutrient data, including sodium intake. A secondary data analysis was conducted to examine sodium consumption patterns at baseline and at one-year study visits. Sodium consumption patterns over time were examined using linear mixed models. RESULTS: The percentage of meals reported eaten in the home at both baseline and one-year follow-up was approximately 69%. Follow-up for the one-year dietary intervention revealed that the participants who consumed sodium greater than 2,300 mg/d declined from 75% (at baseline) to 59%, and those that consumed higher than 1,500 mg/d declined from 96% (at baseline) to 85%. Average sodium intake decreased from 2,994 mg at baseline to 2,558 mg at one-year (P < 0.001), and the sodium potassium ratio also decreased from 1.211 to 1.047 (P < 0.001). Sodium intake per meal varied significantly by meal type, location, and weekday, with higher intake at dinner, in restaurants, and on weekends. At-home lunch and dinner sodium intake decreased (P < 0.05), while dinner sodium intake at restaurant/fast food chains increased from baseline to one-year (P < 0.05). CONCLUSION: Sodium intake for the majority of participants exceeded the recommended dietary guidelines. Findings support actions that encourage low-sodium food preparation at home and encourage public health policies that decrease sodium in restaurants and prepared foods.

Introducción: La normohidratación es uno de los mayores objetivos en hemodiálisis (HD) y diálisis peritoneal (DP). La bioimpedancia por espectroscopia (BIS) se postula como el método más prometedor para la evaluación y seguimiento del estado de hidratación en pacientes en diálisis. Objetivo: Comparar la composición corporal de pacientes prevalentes en HD y DP en un intervalo de seis meses. Pacientes y métodos: Estudio observacional de 62 pacientes en HD y 19 en DP comparando los parámetros clínicos, bioquímicos y de bioimpedancia. Resultados: En el estudio comparativo, los pacientes en DP fueron más jóvenes (50 ± 10 vs. 57 ± 14 años, p = 0,031). El índice de comorbilidad de Charlson (4,8 ± 3 vs. 7,5 ± 3, p < 0,001), tiempo en diálisis (16,9 ± 18,01 vs. 51,88 ± 68,79 meses, p = 0,020) y proteína C reactiva [3 (3-9,3) vs. 5,25 (1-76,4)] fueron menores. Los niveles de proteínas totales (7,46 ± 0,44 vs. 7,04 ± 0,55 g/dl, p = 0,005), y transferrina (205 ± 41 vs. 185 ± 29 mg/dl, p = 0,024) fueron más elevados. BIS: agua intracelular (AIC) (19,67 ± 3,61 vs. 16,51 ± 3,36 litros, p = 0,010), masa muscular total (MM) (37,20 ± 8,65 vs. 32,57 ± 8,72 kg, p = 0,029), masa celular total (MCT) (20,53 ± 5,65 vs. 17,56 ± 5,91 kg, p = 0,033) y ángulo de fase (Phi 50) (5,81 ± 0,86 vs. 4,74 ± 0,98, p = 0,000) fueron más elevados que en HD. Sobrehidratados 22% en HD y 10% en DP, en las condiciones referidas en métodos. A los seis meses en DP observamos aumento de peso (73,75 ± 12,27 vs. 75,22 ± 11,87 kg, p = 0,027), grasa total (MG) (26,88 ± 10 vs. 30,02 ± 10 kg, p = 0,011) y relativa (MG %) (35,75 ± 9,87 vs. 39,34 ± 9,12, p = 0,010); disminución de AIC (18,56 ± 3,45 vs. 17,65 ± 3,69 l, p = 0,009), MM (36,95 ± 8,88 vs. 34 ± 9,70 kg, p = 0,008) y MM relativa (MM %) (50,85 ± 12,33 vs. 45,40 ± 11,95%, p = 0,012). En el análisis multivariante, la variación (DELTA) de peso guarda relación con el DELTA de grasa (p < 0,001). Encontramos correlación entre el incremento de grasa y el decremento de masa muscular (p = 0,01). A los seis meses en HD no se observaron cambios en estos parámetros, salvo una reducción en el agua extracelular (15,11± 2,45 vs. 14,00 ± 2,45, p = 0,001). Conclusiones: BIS permite valorar los cambios en la composición corporal y ayuda a establecer el peso seco e introducir cambios en las pautas de tratamiento (AU)
Introduction: Proper hydration is one of the major aims in haemodialysis (HD) and peritoneal dialysis (PD). Bioimpedance spectroscopy appears to be a promising method for the evaluation and follow up of the hydration status in dialysis patients (P). Objectives: We compared body composition between stable patients on HD and PD after six months. Patients and method: An observational study with 62 P on HD and 19 P on PD was performed. Clinical, biochemical and bioimpedance parameters were analysed. Results: In the comparative study, PD P were younger (50±10 vs 57±14 years, P=.031). The Charlson Comorbidity Index (4.8±3 vs 7.5±3, P<.001), time on dialysis (16.9±18.01 vs 51.88±68.79 months, P=.020) and C-Reactive Protein [3 (3-9.3) vs 5.25 (1-76.4)] were lower. Total protein levels (7.46±0.44 vs 7.04±0.55 g/dl, P=.005) and transferrin levels (205±41 vs 185±29 mg/dl, P=.024) were higher. BIS: Intracellular water (19.67±3.61 vs 16.51±3.36 litres, P=.010), lean tissue mass (LTM) (37.20±8.65 vs 32.57±8.72 kg, P=.029), total cellular mass (TCM) (20.53±5.65 vs 17.56±5.91 kg, P=.033), and bioelectrical impedance phase angle (Phi 50) (5.81±0.86 vs 4.74±0.98, P=.000) were higher than in HD P. Overhydration: 22% in HD y 10% in PD, in conditions referred to in methods. Six months later, PD P increased in weight (73.75±12.27 vs 75.22±11.87 kg, P=.027), total fat (FAT) (26.88±10 vs 30.02±10 kg, P=.011) and relative fat (Rel FAT) (35.75±9.87 vs 39.34±9.12, P=.010); and decreased in ICW (18.56±3.45 vs 17.65±3.69 l, P=.009), LTM (36.95±8.88 vs 34±9.70 kg, P=.008) and relative LTM (Rel LTM) (50.85±12.33 vs 45.40±11.95%, P=.012). In the multivariate analysis, weight variation (DELTA) was related to DELTA FAT (P<.001). We found a correlation between fat increase and lean tissue mass decrease. Six months later, in HD P, we observed a reduction in ECW (15.11±2.45 vs 14.00±2.45, P.001), without changes in other parameters. Conclusions: Bioelectrical impedance analysis facilitates the assessment of changes in body composition so as to correct dry weight and to introduce changes in treatment schedule (AU)
