RESUMO

A comparison of low-cost radon monitors was conducted at the Laboratory of Natural Radiation (LNR). The monitors we evaluated were EcoQube, RadonEye, RadonEye Plus2, Spirit, ViewPlus, ViewRadon and WavePlus. An AlphaGUARD monitor calibrated at the Laboratory of Environmental Radioactivity of the University of Cantabria (LaRUC), accredited for testing and calibration according to ISO/IEC 17025, provided the reference value of radon concentration. The temporal stability of the monitors was studied, obtaining a percentage of missing records ranged from 1% to 19% of the data. The main technical characteristics studied were temporal stability, measurement ranges, accuracy, correlation and response time. The main results show that the measurement ranges align with those specified by their manufacturers, with percentage differences with respect to the reference monitor of between 5% and 16%. The diversity found for response time is remarkable, with values ranging from 1 to 15 h, with Pearson correlation factors between 0.63 and 0.90.

RESUMO

AIM: assess the prescription of oral nutritional supplements (ONS) in the Northern Area of Gran Canaria in the period 2016-2021. MATERIALS AND METHODS: based on electronic prescription data, the first ONS prescription during 2016-2021 was analyzed considering age, gender, nutritional requirements (NR), body mass index (BMI), percentage of weight loss (%WL), albumin and number of prescribed ONS per patient. RESULTS: 10,595 prescriptions were identified corresponding to 6661 patients with the following characteristics: 46.3 % men, mean age 72.84 ± 15.93 years, BMI 20.60 ± 3.98 kg/m2, %WL 11.89 ± 8.32 %; albumin 3.08 ± 0.63 g/dl. The most frequent etiologies of DRE were: neoplasms 42.6 %; degenerative processes of the CNS 28.9 %; stroke 3.9 %; short intestine 6.9 %, and inflammatory bowel disease (IBD) 5.5 %. The percentages of NR covered by the prescribed ONS were: 100 % in 8.9 % of cases, 50 % in 36.9 %, and 25 % in 54.2 %; 40.4 % of patients received 1 unit of ONS daily, 36.3 % took 2 units of ONS, and 23 % received > 3 units of ONS per day. Greater NR were associated with a greater number of ONS (p < 0.001), but 40.8 % of patients who needed to cover > 50 % of NR received only one unit of ONS. CONCLUSION: a significant percentage of patients with DRM do not receive a number of ONS according to their NR.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the impact of an enhanced ONS (enriched in EPA, DHA, leucine, and beta-glucans) on the dietary intake of cancer patients. METHODS: A randomized, double-blind, parallel, controlled, and multicenter clinical trial was conducted in patients with cancer and malnutrition. The trial compared prescribed dietary advice and two packs per day, for 8 weeks, of a hypercaloric (400 kcal/pack) and hyperproteic ONS (20 g/pack) with fiber and specific ingredients (leucine, EPA and DHA, and beta-glucans) (enhanced-ONS) versus an isocaloric and isoproteic formula (standard-ONS) without specific ingredients. Food intake was assessed with a 3-day dietary survey, and adherence to the supplement with a patient self-completed diary. RESULTS: Thirty-seven patients completed the intervention period. The combined intervention of dietary advice and ONS managed to increase the energy intake of the overall cohort by 792.55 (378.57) kcal/day, protein by 40.72 (19.56) g/day. Increases in energy and nutrient intakes were observed in both groups, both in dietary intake and associated exclusively with the supplement. The group that received the enhanced-ONS ingested a greater volume of product when there was a greater severity of malnutrition; a tumor location in the head, neck, upper digestive area, liver, or pancreas; more advanced stages of the tumor; or the receipt of more than one antineoplastic treatment. CONCLUSION: The use of an enhanced-ONS helps meet the nutritional requirements of cancer patients, especially those who have a more compromised clinical condition, with high adherence, good tolerance, and acceptance.

RESUMO

BACKGROUND: The Supreme Court's decision in Students for Fair Admissions, Inc., v. Harvard College is likely to result in the matriculation of fewer students from historically excluded racial/ethnic groups at more selective colleges and universities and matriculation of more students at less selective colleges and universities. Because of this, it is important to understand how resources for pre-health advising, a modifiable factor that can help increase the diversity of the health workforce, vary across institutions with differing levels of selectivity. Colleges are known to vary in resources, structure, and investment in pre-health advising but data are lacking and there is no estimate of any pre-health advising resource gap. PURPOSE: To quantify availability of advising resources and identify perceived challenges in pre-health advising in California's highly diverse public and select private undergraduate institutions. METHODS: Structured 60-minute Zoom interviews from June 2022 -October 2022 at 18/23 CSU (California State Universities), 9/9 University of California (UC) institutions and 6 select private institutions with varying levels of selectivity. Two investigators independently analyzed interviews using a Grounded Theory Approach. The full study team reviewed transcripts and themes. KEY RESULTS: Pre-health advisor capacity varied greatly across the three types of institutions. CSU: mean = 1 FTE advisor: 24,620 graduates (range: 1: 1,059-1: 150,520); UC mean = 1 FTE advisor: 4,526 graduates (range: 1: 1,912-1: 10,920); private institutions mean = 1 FTE advisor:1,794 graduates (range: 1: 722-1: 5,300). Participants reported common challenges: advising capacity, lack of advisor training, advisor turnover, and student difficulties in accessing clinical opportunities and required coursework. CSU and UC participants noted that these had greatest impact for first generation and racially/ethnically underrepresented students for whom lack of informal professional networks, lack of other mentors, and financial responsibilities complicate college navigation and professional school application. CONCLUSIONS: Students at CSU campuses had 5 times less access to pre-health advising per graduate than UC students, and 13 times less than students at private institutions. Much greater investment is needed in California's public institutions, particularly CSUs, to increase equity in access to advising for pre-health professional students. Research should examine pre-health advising resource capacity in other states, especially those that are now facing race-neutral admissions policies at undergraduate institutions and health professions schools.

RESUMO

Introduction and objectives The optimal antithrombotic strategy following left atrial appendage closure (LAAC) is poorly defined in patients with nonvalvular atrial fibrillation. We assessed the safety and effectiveness of a single antiplatelet treatment (SAPT) strategy after LAAC in a population at high risk of ischemic and bleeding events. Methods This single-center, observational, prospective study included a consecutive cohort of patients who underwent LAAC using the LAmbre device (Lifetech Scientific, China) and who were discharged with SAPT. The primary outcome was a composite of stroke, systemic embolism, and device-related thrombosis during follow-up. Secondary endpoints were cardiovascular mortality and major bleeding events (BARC ≥3a). Clinical follow-up was performed at 1, 6, and 12 months and subsequently on an annual basis. Transesophageal echocardiography was performed at 1 and 12 months of follow-up. Results The study comprised 74 patients. The median age was 77 [72-83] years and 43% were women. The cohort exhibited a high prevalence of comorbidities and cardiovascular risk factors. The median CHA2DS2-VASc and HAS-BLED scores were 4 [3-6] and 4 [4-5], respectively. The median length of follow-up was 2.5 years (188 patients-year). During follow-up, device-related thrombosis occurred in 3 patients (4%). Ischemic stroke occurred in 1 patient (1.3%, rate 0.5%/y), representing a 90.9% relative risk reduction compared with the risk predicted by CHA2DS2-VASc. Major bleeding events occurred in 12 patients (16%, 6.4%/y), with a relative risk reduction of 26.4% of that predicted by HAS-BLED. Cardiovascular-related mortality was observed in 2 patients (2.7%). Conclusions SAPT appears to be a safe and effective treatment following LAAC in patients at high ischemic and hemorrhagic risk. Further studies are needed to confirm our findings (AU)


Introducción y objetivos Se desconoce cuál es la terapia antitrombótica óptima tras el cierre percutáneo de la orejuela izquierda (CPOI) en pacientes con fibrilación auricular no valvular. El objetivo de este estudio es analizar la efectividad y la seguridad de un régimen de tratamiento antiagregante plaquetario simple (TAPS) tras el CPOI en una población con alto riesgo isquémico y hemorrágico. Métodos Estudio observacional prospectivo que incluyó una cohorte consecutiva de pacientes a los que se realizó CPOI con dispositivo LAmbre (Lifetech Scientific, China) y que recibieron TAPS al alta. El evento primario fue un combinado de ictus, embolia sistémica y trombosis del dispositivo. Los eventos secundarios fueron mortalidad cardiovascular y hemorragia mayor (BARC ≥ 3a). Se realizó seguimiento clínico al mes y a los 6 y 12 meses y cada año después. Se realizó ecocardiograma transesofágico al mes y a los 12 meses. Resultados Se incluyó a 74 pacientes (el 43% mujeres) con una mediana de edad de 77 [intervalo intercuartílico, 72-83] años, que presentaban gran comorbilidad y factores de riesgo cardiovascular. Los valores de CHA2DS2-VASc y HAS-BLED fueron una mediana de 4 [3-6] y 4 [4-5] respectivamente. Durante el seguimiento (mediana, 2,5 años), 3 pacientes (4%) presentaron trombosis del dispositivo. Uno sufrió ictus isquémico (1,3%, 0,5%/año), lo que supone, según la incidencia esperada por CHA2DS2-VASc, una reducción del riesgo relativo del 90,9%. Sufrieron eventos hemorrágicos 12 pacientes (16%; 6,4%/año), una tasa el 26,4% menor que el riesgo HAS-BLED predicho. Se produjo la muerte cardiovascular de 2 pacientes (2,7%). Conclusiones Una estrategia de TAPS tras el CPOI parece ser una opción efectiva y segura para los pacientes con altos riesgos isquémico y hemorrágico. Se necesitan más estudios que corroboren nuestros resultados (AU)

RESUMO

Crops have resource-acquisitive leaf traits, which are usually attributed to the process of domestication. However, early choices of wild plants amenable for domestication may also have played a key role in the evolution of crops' physiological traits. Here we compiled data on 1,034 annual herbs to place the ecophysiological traits of 69 crops' wild progenitors in the context of global botanical variation, and we conducted a common-garden experiment to measure the effects of domestication on crop ecophysiology. Our study found that crops' wild progenitors already had high leaf nitrogen, photosynthesis, conductance and transpiration and soft leaves. After domestication, ecophysiological traits varied little and in idiosyncratic ways. Crops did not surpass the trait boundaries of wild species. Overall, the resource-acquisitive strategy of crops is largely due to the inheritance from their wild progenitors rather than to further breeding improvements. Our study concurs with recent literature highlighting constraints of crop breeding for faster ecophysiological traits.

RESUMO

BACKGROUND: Up to 20% of COVID-19 patients can suffer COVID-19-related myocardial injury. Elevated cardiac biomarkers, such as hs-cTnT and NT-proBNP, have been related to worse short-term prognosis. However, data on NT-proBNP and long-term prognosis are scarce. We have evaluated the potential association of baseline age-adjusted NT-proBNP levels and outcomes at one-year follow-up in COVID-19 patients. METHODS: This was a single-center prospective study of 499 COVID-19 patients in whom NT-proBNP was assessed at hospital admission. NT-proBNP levels were age-adjusted and patients were classified as high or low NT-proBNP. Clinical and demographic characteristics, comorbidities, laboratory results, and in-hospital complications and mortality were compared between the two groups. Survivors of the acute phase of COVID-19 were followed up for one year from admission to detect readmissions and mortality. RESULTS: The 68 patients with high NT-proBNP levels at hospital admission were older, with more cardiovascular risk factors, cardiovascular disease, comorbidities, myocardial injury, and higher levels of inflammatory markers than patients with low NT-proBNP levels. They also had more in-hospital complications and a higher acute-phase mortality rate (60.3% vs. 10.2%, p < 0.001). High NT-proBNP levels were an independent marker of death during hospitalization (HR 1.95; CI 1.07-3.52). At one-year follow-up, high NT-proBNP levels were independently associated with mortality (HR 2.69; CI 1.47-4.89). Among survivors of the acute phase of COVID-19, there were no differences in hospital readmissions between those with high vs. low NT-proBNP levels, but survivors with high baseline NT-proBNP levels showed a higher 1-year mortality rate (7.4% vs. 1.3%, p = 0.018). CONCLUSIONS: High age-adjusted NT-proBNP levels at the time of hospital admission for COVID-19 are associated with poor short and long-term prognosis. High NT-proBNP seems also to be related to worse prognosis in survivors of the acute phase of COVID-19. A closer follow-up on these patients may be crucial.

RESUMO

AIMS: This work aims to evaluate the efficacy of nutritional supplementation with a glutamine-enriched oligomeric diet (GEOD) compared to a standard polymeric diet (SPD) in terms of oncology treatment-related diarrhea (OTRD) (frequency and consistency of stools), gastrointestinal toxicity, and functional and nutritional progress. METHODS: This prospective cohort study compared two groups of patients with rectal cancer in treatment with neoadjuvant chemotherapy and radiotherapy who were at risk of malnutrition. Patients were randomized to receive either 400 ml of GEOD or of SPD from the start of radiotherapy to 30 days after its completion. RESULTS: Eighty patients were recruited, 40 per arm. The GEOD arm had improved stool consistency and a greater reduction in the number of stools compared to the SPD arm (p < 0.001). The relative risk (RR) of developing diarrhea in the GEOD arm was 0.059 (95% CI 0.015-0.229). There was a reduced risk of developing intestinal mucositis in the GEOD arm compared to the SPD arm [RR 0.202 (95% CI 0.102 - 0.399)]. The GEOD arm had greater improvements in functional and nutritional status (p < 0.001). CONCLUSIONS: GEOD had a protective effect in terms of the development of gastrointestinal toxicity associated with chemotherapy and radiotherapy treatment in patients with rectal cancer.

RESUMO

BACKGROUND: The 2014 adoption of the Milestone ratings system may have affected evaluation bias against minoritized groups. OBJECTIVE: To assess bias in internal medicine (IM) residency knowledge ratings against Black or Latino residents-who are underrepresented in medicine (URiM)-and Asian residents before versus after Milestone adoption in 2014. DESIGN: Cross-sectional and interrupted time-series comparisons. SETTING: U.S. IM residencies. PARTICIPANTS: 59 835 IM residents completing residencies during 2008 to 2013 and 2015 to 2020. INTERVENTION: Adoption of the Milestone ratings system. MEASUREMENTS: Pre-Milestone (2008 to 2013) and post-Milestone (2015 to 2020) bias was estimated as differences in standardized knowledge ratings between U.S.-born and non-U.S.-born minoritized groups versus non-Latino U.S.-born White (NLW) residents, with adjustment for performance on the American Board of Internal Medicine IM certification examination and other physician characteristics. Interrupted time-series analysis measured deviations from pre-Milestone linear bias trends. RESULTS: During the pre-Milestone period, ratings biases against minoritized groups were large (-0.40 SDs [95% CI, -0.48 to -0.31 SDs; P < 0.001] for URiM residents, -0.24 SDs [CI, -0.30 to -0.18 SDs; P < 0.001] for U.S.-born Asian residents, and -0.36 SDs [CI, -0.45 to -0.27 SDs; P < 0.001] for non-U.S.-born Asian residents). These estimates decreased to less than -0.15 SDs after adoption of Milestone ratings for all groups except U.S.-born Black residents, among whom substantial (though lower) bias persisted (-0.26 SDs [CI, -0.36 to -0.17 SDs; P < 0.001]). Substantial deviations from pre-Milestone linear bias trends coincident with adoption of Milestone ratings were also observed. LIMITATIONS: Unobserved variables correlated with ratings bias and Milestone ratings adoption, changes in identification of race/ethnicity, and generalizability to Milestones 2.0. CONCLUSION: Knowledge ratings bias against URiM and Asian residents was ameliorated with the adoption of the Milestone ratings system. However, substantial ratings bias against U.S.-born Black residents persisted. PRIMARY FUNDING SOURCE: None.

RESUMO

Cathepsin D is a protease that is an effector in the immune response of macrophages, yet to date, only a limited number of probes have been developed for its detection. Herein, we report a water soluble, highly sensitive, pH insensitive fluorescent probe for the detection of Cathepsin D activity that provides a strong OFF/ON signal upon activation and with bright emission at 515 nm. The probe was synthesised using a combination of solid and solution-phase chemistries, with probe optimisation to increase its water solubility and activation kinetics by addition of a long PEG chain (5 kDa) at the C-terminus. A BODIPY fluorophore allowed detection of Cathepsin D across a wide pH range, important as the protease is active both at the low pH found in lysosomes and also in higher pH phagolysosomes, and in the cytosol. The probe was successfully used to detect Cathepsin D activity in macrophages challenged by exposure to bacteria.

RESUMO

ABSTRACT: Unhealthy alcohol use (UAU) affects nearly 1 in 4 Latinx/o/a individuals in the United States (US). Compared with White individuals, Latinx/o/a individuals with UAU face increased morbidity, decreased access to addiction treatment, and higher rates of incarceration. Community health workers (CHWs), also known as promotores, provide culturally and linguistically informed services while augmenting social and health care interventions. Although there is extensive literature evaluating the role of CHW interventions for chronic conditions including hypertension and diabetes, less is known about CHW interventions for UAU in the US. To better understand how CHWs can address UAU in the Latinx/o/a community in the US, we performed a scoping review of the literature for CHW interventions for UAU in the Latinx/o/a population. We reviewed publications up to March 8, 2022, which described CHW interventions for UAU in Latinx/o/a individuals in the US and identified 6 publications that met inclusion criteria after full-text review. These publications included 3 randomized controlled trials, 2 follow-up feasibility and acceptability assessments within the randomized controlled trial intervention group, and a pre-post noncontrolled feasibility study. All interventions were brief, with low-intensity touchpoints between CHWs and patients. None included medications for alcohol use disorder. We found few publications related to CHW-delivered interventions for UAU within the Latinx/o/a population. Given the acceptance and success of CHW-delivered interventions other conditions, as well as the increasing use of CHWs in the US, we need to invest in research that examines the efficacy of the CHWs in UAU.

RESUMO

The application of Laser-Induced Breakdown Spectroscopy (LIBS) in forensic science has garnered increasing attention. The ability to perform real-time, on-site analysis of Gunshot Residue (GSR) particles and potential elements originating from bullets or projectile cores on various surfaces holds the potential to assist in resolving firearms-related cases. This includes facilitating trajectory determination by locating distinct impact points and identifying the types of ammunition used. This study evaluates the utilization of a portable LIBS device for ballistic forensic purposes. Additionally, it focuses on the assessment of potential false positives and false negatives arising from the different materials where the shots have been fired. Since the system performs laser ablation of both surface particles and the substrate, it emphasizes the importance of conducting preliminary screening in an area with the same composition as the impact zone to minimize potential false positives during direct surface analysis. Furthermore, the results demonstrate the capability to detect the constituent elements of characteristic gunshot residue particles (GSR particles): lead (Pb), antimony (Sb), and barium (Ba) adhering to bullets, as well as the principal elements composing the jacket or core of the projectile: lead (Pb), copper (Cu), and zinc (Zn) through direct analysis, without the need for a sampling kit, on different surfaces such as walls, furniture, or fabrics. Analyses conducted a month after the shots were fired indicate the potential for finding residues in the vicinity of the bullet hole. Analyses conducted a month after the shots were fired indicate the possibility of finding residues in the area around the bullet hole.

RESUMO

PROBLEM: Enhancing workforce diversity by increasing the recruitment of students who have been historically excluded/underrepresented in medicine (UIM) is critical to addressing healthcare inequities. However, these efforts are inadequate when undertaken without also supporting students' success. The transition to clerkships is an important and often difficult to navigate inflection point in medical training where attention to the specific needs of UIM students is critical. INTERVENTION: We describe the design, delivery, and three-year evaluation outcomes of a strengths-based program for UIM second year medical students. The program emphasizes three content areas: clinical presentations/clinical reasoning, community building, and surfacing the hidden curriculum. Students are taught and mentored by faculty, residents, and senior students from UIM backgrounds, creating a supportive space for learning. CONTEXT: The program is offered to all UIM medical students; the centerpiece of the program is an intensive four-day curriculum just before the start of students' second year. Program evaluation with participant focus groups utilized an anti-deficit approach by looking to students as experts in their own learning. During focus groups mid-way through clerkships, students reflected on the program and identified which elements were most helpful to their clerkship transition as well as areas for programmatic improvement. IMPACT: Students valued key clinical skills learning prior to clerkships, anticipatory guidance on the professional landscape, solidarity and learning with other UIM students and faculty, and the creation of a community of peers. Students noted increased confidence, self-efficacy and comfort when starting clerkships. LESSONS LEARNED: There is power in learning in a community connected by shared identities and grounded in the strengths of UIM learners, particularly when discussing aspects of the hidden curriculum in clerkships and sharing specific challenges and strategies for success relevant to UIM learners. We learned that while students found unique benefits to preparing for clerkships in a community of UIM students, near peers, and faculty, future programs could be enhanced by pairing this formal intensive curriculum with more longitudinal opportunities for community building, mentoring, and career guidance.

RESUMO

Introduction: Mental health promotion and screenings are recommended as part of standard preventive care. Mexican immigrants in the U.S. are at high risk for mental health illness especially after the COVID-19 pandemic, however access to mental health prevention for this population has been limited, which results in important implementation and equity gaps. The Ventanilla de Salud (VDS) program provides preventive services through Mexican consulates in the U.S. Objective: The objective of this study was to assess capability, opportunity, and motivation for promotores to implement mental health programming through the VDS, leveraging early experiences of ongoing mental health prevention efforts. Methods: This was a qualitative study using the Capability, Opportunity, and Motivation for Behavior Change model (COM-B). We conducted 9 focus groups with 40 VDS promotores and 6 semi-structured interviews with program stakeholders. Data were analyzed using inductive and deductive coding. Results: We found high levels of interest from the leadership, partners, and promotores to provide mental health services through the VDS. Early implementation of a mental health strategy that included training sessions for promotores and mental health promotion, screenings and referrals for VDS users was ongoing. We identified facilitators and barriers that could affect capability, opportunity, and motivation to provide mental health services. Facilitators included promotores' extensive knowledge about the importance of mental health, promotores service mindset and commitment to provide services to VDS users, and general support from the VDS network and partners. Barriers included promotores' turnover, need for additional economic compensation, burnout, competing priorities, and lack of mental health professionals to provide clinical services or supervision. Additional investments are recommended to support promotores' well-being. Conclusion: The main lesson learned from this study was that investing in VDS promotores' training, resources, and well-being is key to their capability, opportunity and motivation to provide mental health services for Mexican immigrants in the US. Results from this study can be applied to improve the ongoing VDS mental health strategy and increase its impact on the mental health of Mexican immigrants.

RESUMO

OBJECTIVE: To test whether a series of brief, psychologically informed educational videos added to physical therapy improved function among adolescents with patellofemoral pain. The secondary aims were to assess pain and psychological beliefs. DESIGN: A double-blinded randomized controlled trial. METHODS: Sixty-eight adolescents with patellofemoral pain were randomly assigned to view brief, psychologically informed videos (n = 34) or control videos (n = 34) in addition to usual care physical therapy. The psychologically informed videos targeted fear-avoidance beliefs, kinesiophobia, and pain catastrophizing. The control videos conveyed basic anatomy, biomedical factors, and lower extremity mechanics. Outcomes were assessed at baseline, 3 weeks, 6 weeks (primary end point), and 3 months. The primary outcome was change in the Anterior Knee Pain Scale. Secondary outcomes were changes in Numeric Pain-Rating Scale and psychological beliefs (Modified Fear-Avoidance Beliefs Questionnaire-Physical Activity, Tampa Kinesiophobia Scale-11, and Pain Catastrophizing Scale-Child). RESULTS: Adolescents in the psychologically informed group experienced significantly greater improvements in function (Anterior Knee Pain Scale mean difference = 8 points; 95% CI: 2.2, 13.2; P = .01) and pain (Numeric Pain-Rating Scale mean difference = 1.2 points; 95% CI: 0.1, 2.4; P = .04) at 6 weeks compared to the control group. The psychologically informed group had significantly greater reductions in psychological beliefs over time than the control group (P≤.001; partial η2 = 0.32). CONCLUSION: Incorporating psychologically informed education into physical therapy care improved function, pain, and psychological beliefs to a greater extent than the control group.

RESUMO

Water use has been increasing globally by 1% per year, and recycling and re-use are critical issues compromised by the presence of pollutants. In this context, the design of novel materials and/or procedures for the large scale-removal of pollutants must be economically and environmentally feasible in order to be considered as part of the solution by emerging economies. We demonstrate that the cross-linking of biodegradable polysaccharides such as starch, dextrin, or dextrin and ß-cyclodextrin with divinyl sulfone is an innovative strategy for synthesizing insoluble and eco-friendly sorbent polymers, including pSt, pDx and pCD-Dx. The evaluation of these polymers' ability to remove ciprofloxacin (CIP), a prime example of antibiotic pollution, revealed that pSt, with a Kd of 1469 L/kg and a removal rate higher than 92%, is a favorable material. Its sorption is pH-dependent and enhanced at a mildly alkaline pH, allowing for the desorption (i.e., cleaning) and reuse of pSt through an environmentally friendly treatment with 20 mM AcONa pH 4.6. The facts that pSt (i) shows a high affinity for CIP even at high NaCl concentrations, (ii) can be obtained from affordable starting materials, and (iii) is synthesized and regenerated through organic, solvent-free procedures make pSt a novel sustainable material for inland water and seawater remediation, especially in less developed countries, due to its simplicity and low cost.

RESUMO

Introducción: las fórmulas nutricionales específicas para diabetes (FED) suelen presentar una composición que favorece simultáneamente su palatabilidad y el control glucémico y metabólico.Objetivo: comparar la aceptación sensorial de un FED respecto a un suplemento nutricional oral estándar (FE) en pacientes en riesgo de desnutrición con diabetes mellitus tipo 2.Método: ensayo clínico, aleatorizado, doble ciego, cruzado, multicéntrico y controlado. Se evaluó, a través de una escala del 1 al 4, el olor, el sabor y la textura percibida de un FED y de un FE.Resultados: se reclutaron a 29 pacientes y 58 evaluaciones sensoriales de los suplementos. Se observó una mejor valoración de la FED respecto a la FE, aunque no se alcanzaron diferencias estadísticamente significativas: olor, 0,04 (IC 95 %), de -0,49 a 0,56 (p = 0,092); sabor, 0,14 (IC 95 %), de -0,35 a 0,63 (p = 0,561); textura, 0,14, (IC 95 %), de -0,43 a 0,72 (p = 0,619). No se encontraron diferencias cuando se analizaron por orden de aleatorización, sexo, grado de desnutrición, mayor o menor grado de complejidad, mayor o menor tiempo de evolución de la diabetes, ni por ser más o menos mayores. Conclusiones: el suplemento nutricional específico para paciente con diabetes, formulado con aceite de oliva virgen extra, EPA y DHA, una mezcla específica en hidratos de carbono, fibra soluble e insoluble, presentó una adecuada aceptación sensorial del paciente desnutrido con diabetes mellitus tipo 2.(AU)


Introduction: oral nutritional supplements specific for diabetes (DSF) usually have a composition that favors their palatability and simultaneous glycemic and metabolic control. Objective: to compare the sensory acceptability of a DSF with respect to a standard oral nutritional supplement (STF) in patients at risk of malnutrition with type 2 diabetes mellitus. Method: randomized, double-blind, crossover, multicenter, controlled, double-blind clinical trial. Odor, taste and perceived texture of a DSF and a STD were evaluated using a scale of 1 to 4. Results: twenty-nine patients were recruited and 58 organoleptic evaluations of the supplements were registered. A better evaluation of DSF was observed with respect to STD, although no statistically significant differences were reached: odor, 0.04 (CI 95 %) -0.49 to 0.56 (p = 0.092); taste, 0.14 (CI 95 %), -0.35 to 0.63 (p = 0.561); texture, 0.14 (CI 95 %), -0.43 to 0.72 (p = 0.619). No differences were found when analyzed by order of randomization, sex, degree of malnutrition, greater or lesser degree of complexity, greater or lesser time of evolution of diabetes, or by being older or younger. Conclusions: the specific nutritional supplement for diabetic patients formulated with extra virgin olive oil, EPA and DHA, a specific mixture of carbohydrates, and fiber, presented an adequate sensory acceptance by malnourished patients with type 2 diabetes mellitus.(AU)
