A Technological Tool Aimed at Self-Care in Patients With Multimorbidity: Cross-Sectional Usability Study.

BACKGROUND: Information and communication technologies (ICTs) have been positioned as useful tools to facilitate self-care. The interaction between a patient and technology, known as usability, is particularly important for achieving positive health outcomes. Specific characteristics of patients with chronic diseases, including multimorbidity, can affect their interaction with different technologies. Thus, studying the usability of ICTs in the field of multimorbidity has become a key element to ensure their relevant role in promoting self-care. OBJECTIVE: The aim of this study was to analyze the usability of a technological tool dedicated to health and self-care in patients with multimorbidity in primary care. METHODS: A descriptive observational cross-sectional usability study was performed framed in the clinical trial in the primary care health centers of Madrid Health Service of the TeNDER (Affective Based Integrated Care for Better Quality of Life) project. The TeNDER technological tool integrates sensors for monitoring physical and sleep activity along with a mobile app for consulting the data collected and working with self-management tools. This project included patients over 60 years of age who had one or more chronic diseases, at least one of which was mild-moderate cognitive impairment, Parkinson disease, or cardiovascular disease. From the 250 patients included in the project, 38 agreed to participate in the usability study. The usability variables investigated were effectiveness, which was determined by the degree of completion and the total number of errors per task; efficiency, evaluated as the average time to perform each task; and satisfaction, quantified by the System Usability Scale. Five tasks were evaluated based on real case scenarios. Usability variables were analyzed according to the sociodemographic and clinical characteristics of patients. A logistic regression model was constructed to estimate the factors associated with the type of support provided for task completion. RESULTS: The median age of the 38 participants was 75 (IQR 72.0-79.0) years. There was a slight majority of women (20/38, 52.6%) and the participants had a median of 8 (IQR 7.0-11.0) chronic diseases. Thirty patients completed the usability study, with a usability effectiveness result of 89.3% (134/150 tasks completed). Among the 30 patients, 66.7% (n=20) completed all tasks and 56.7% (17/30) required personalized help on at least one task. In the multivariate analysis, educational level emerged as a facilitating factor for independent task completion (odds ratio 1.79, 95% CI 0.47-6.83). The median time to complete the total tasks was 296 seconds (IQR 210.0-397.0) and the median satisfaction score was 55 (IQR 45.0-62.5) out of 100. CONCLUSIONS: Although usability effectiveness was high, the poor efficiency and usability satisfaction scores suggest that there are other factors that may interfere with the results. Multimorbidity was not confirmed to be a key factor affecting the usability of the technological tool.

Comparative study of weekly and three-weekly neoadjuvant carboplatin in triple-negative breast cancer: retrospective analysis in real-world settings.

PURPOSE: Tri-weekly carboplatin is an established neoadjuvant treatment for triple-negative breast cancer, enhancing pathological complete response (pCR) and overall survival. This study explores if weekly carboplatin provides lower toxicity and comparable pCR rates. METHODS/PATIENTS: A retrospective multicenter study (January 2021 to March 2023) compares outcomes of weekly and tri-weekly carboplatin. RESULTS: Among 104 participants, 60% received weekly and 40% tri-weekly treatments. Weekly administration had fewer discontinuations (56.5 vs. 70.7%, p = 0.154). Both schedules exhibited similar overall toxicity (p = 0.087), with slightly higher grade 3-4 toxicity in the tri-weekly group (56.1 vs. 48.4%, p = 0.126). Hematological toxicity was comparable, but the weekly group experienced more diarrhea (p = 0.432) and asthenia (p = 0.012). Weekly treatment correlated with more frequent breast-conserving surgeries (p = 0.004). pCR rates were 50% with weekly and 61% with tri-weekly regimens (p = 0.186). CONCLUSIONS: Weekly carboplatin exhibited comparable toxicity, a trend toward fewer interruptions, and similar pCR rates. Prospective studies are essential for validating these findings.

Assessment of anthropogenic particles content in commercial beverages.

Microplastic (MPs) pollution is a current global concern that is affecting all environmental compartments and food sources. In this work, anthropogenic particles occurrence (MPs and natural and synthetic cellulosic particles), have been determined in 73 beverages packed in different containers. Overall, 1521 anthropogenic particles were found, being the lowest occurrence in water samples (7.2 ± 10.1 items·L-1) while beer had the highest (95.5 ± 91.8 items·L-1). Colourless/white particles were the most detected followed by blue and red colours. The highest mean size was 783 ± 715 µm in soft drinks. Cellulosic, both natural and semisynthetic particles, were the composition mostly found but regarding plastic polymers, it was polyester. Phenoxy resin particles from the can coatings were also identified in all metal containers which indicates that leaching from the packaging may be happening. The total estimated daily intake were 0.077 and 0.159 items·kg-1 body weight (b.w.)·day-1 for children and adult population, respectively.

Detection of elusive DNA copy-number variations in hereditary disease and cancer through the use of noncoding and off-target sequencing reads.

Copy-number variants (CNVs) play a substantial role in the molecular pathogenesis of hereditary disease and cancer, as well as in normal human interindividual variation. However, they are still rather difficult to identify in mainstream sequencing projects, especially involving exome sequencing, because they often occur in DNA regions that are not targeted for analysis. To overcome this problem, we developed OFF-PEAK, a user-friendly CNV detection tool that builds on a denoising approach and the use of "off-target" DNA reads, which are usually discarded by sequencing pipelines. We benchmarked OFF-PEAK on data from targeted sequencing of 96 cancer samples, as well as 130 exomes of individuals with inherited retinal disease from three different populations. For both sets of data, OFF-PEAK demonstrated excellent performance (>95% sensitivity and >80% specificity vs. experimental validation) in detecting CNVs from in silico data alone, indicating its immediate applicability to molecular diagnosis and genetic research.

Clinical outcomes and prognostic factors after HCV clearance with DAA in HIV/HCV-coinfected patients with advanced fibrosis/cirrhosis.

BACKGROUND AND AIMS: We assessed long-term clinical outcomes and prognostic factors for liver disease progression after sustained viral response with direct-acting antivirals in patients coinfected with HIV/HCV with advanced fibrosis or cirrhosis. APPROACH AND RESULTS: A total of 1300 patients who achieved sustained viral response with direct-acting antivirals from 2014 to 2017 in Spain were included: 1145 with compensated advanced chronic liver disease (384 advanced fibrosis and 761 compensated cirrhosis) and 155 with decompensated cirrhosis. The median follow-up was 40.9 months. Overall, 85 deaths occurred, 61 due to non-liver non-AIDS-related causes that were the leading cause of death across all stages of liver disease. The incidence (95% CI) of decompensation per 100 person-years (py) was 0 in patients with advanced fibrosis, 1.01 (0.68-1.51) in patients with compensated cirrhosis, and 8.35 (6.05-11.53) in patients with decompensated cirrhosis. The incidence (95% CI) of HCC per 100 py was 0.34 (0.13-0.91) in patients with advanced fibrosis, 0.73 (0.45-1.18) in patients with compensated cirrhosis, and 1.92 (1.00-3.70) per 100 py in patients with decompensated cirrhosis. Prognostic factors for decompensation in patients with compensated advanced chronic liver disease included serum albumin, liver stiffness measurement (LSM), and fibrosis 4. In this population, LSM and LSM-based posttreatment risk stratification models showed their predictive ability for decompensation and HCC. CONCLUSIONS: Non-liver non-AIDS-related events were the leading causes of morbidity and mortality after direct-acting antiviral cure among coinfected patients with advanced fibrosis/cirrhosis. Among those with compensated advanced chronic liver disease, baseline LSM and posttreatment LSM-based models helped to assess decompensation and HCC risk.

The Effect of Ultrasound on the Extraction and Functionality of Proteins from Duckweed (Lemna minor).

The inclusion of protein in the regular human diet is important for the prevention of several chronic diseases. In the search for novel alternative protein sources, plant-based proteins are widely explored from a sustainable and ecological point of view. Duckweed (Lemna minor), also known as water lentil, is an aquatic plant with potential applications for human consumption due to its protein content and carbohydrate contents. Among all the conventional and novel protein extraction methods, the utilization of ultrasound has attracted the attention of scientists because of its effects on improving protein extraction and its functionalities. In this work, a Box-Behnken experimental design was proposed to optimize the alkaline extraction of protein from duckweed. In addition, an exploration of the effects of ultrasound on the morphological, structural, and functional properties of the extracted protein was also addressed. The optimal extraction parameters were a pH of 11.5 and an ultrasound amplitude and processing time of 60% and 20 min, respectively. These process conditions doubled the protein content extracted in comparison to the value from the initial duckweed sample. Furthermore, the application of ultrasound during the extraction of protein generated changes in the FTIR spectra, color, and structure of the duckweed protein, which resulted in improvements in its solubility, emulsifying properties, and foaming capacity.

The usefulness of the retina for identifying people with type 2 diabetes with prodromal stages of dementia.

Type 2 diabetes (T2D) is associated with cognitive impairment and dementia. The detection of cognitive impairment is important because this population is at higher risk of experiencing difficulties in the self-management of diabetes. Mild cognitive impairment (MCI) often remains undiagnosed due to lack of simple tools for screening at large scale. This represents an important gap in the patients' management because subjects with diabetes and MCI are at high risk of progressing to dementia. Due to its developmental origin as a brain-derived tissue, the retina has been proposed as a potential means of non-invasive and readily accessible exploration of brain pathology. Recent evidence showed that retinal imaging and/or functional tests are correlated with the cognitive function and brain changes in T2D. Simple retinal functional tests (i.e. retinal microperimetry) have proven to be useful as reliable tool for the cognitive evaluation and monitoring in patients with T2D>65 years. This review gives an overall update on the usefulness of retinal imaging in identifying patients with T2D at risk of developing dementia.

Incidence of valganciclovir-related leukopenia and neutropenia in solid organ transplant recipients at high risk of cytomegalovirus disease.

BACKGROUND: Valganciclovir (VGCV) prophylaxis is associated with an increased risk of hematologic side effects. We analyzed the impact of VGCV prophylaxis on leukopenia and neutropenia rates and explored risk factors for its occurrence. METHODS: Retrospective cohort study of adult cytomegalovirus (CMV)-seronegative solid organ transplantation (SOT) recipients of either CMV-seropositive (CMV D+/R-) or CMV-seronegative (CMV D-/R-) donors between July 2005 and March 2019. CMV D+/R- SOT recipients received 3-12 months of VGCV prophylaxis whereas CMV D-/R- SOT recipients received no VGCV prophylaxis. Competing risk regression was used to calculate risk factors for significant neutropenia (neutrophil count < 1000/µL). RESULTS: A total of 430 CMV-seronegative SOT recipients (median age of 52.1 years, 76.5% males) were included, of which 203 (47.2%) were CMV D+/R- and 227 (52.8%) CMV D-/R-. The unadjusted incidence rate ratio of significant neutropenia attributable to VGCV exposure in the first year post-transplant was 13.50 (95% confidence interval 7.36-27.11). Acute rejection occurred more frequently in neutropenic patients at 32.5% compared to 19.1% in those without neutropenia (p = .033). On multivariate analysis, VGCV prophylaxis for 1-90 days and 91-180 days versus no VGCV were the strongest risk factors for significant neutropenia with a sub-distribution hazard ratio of 39.6 (95% CI, 8.57-182.6) and 13.2 (95% CI, 5.46-32.0), respectively. CONCLUSIONS: VGCV prophylaxis is limited by high rates of neutropenia. Future prospective studies are needed to assess alternative CMV prophylactic strategies in SOT recipients.

Ultrasound in the Study of Thoracic Diseases: Innovative Aspects

Thoracic ultrasound (TU) has rapidly gained popularity over the past 10 years. This is in part because ultrasound equipment is available in many settings, more training programmes are educating trainees in this technique, and ultrasound can be done rapidly without exposure to radiation.The aim of this review is to present the most interesting and innovative aspects of the use of TU in the study of thoracic diseases.In pleural diseases, TU has been a real revolution. It helps to differentiate between different types of pleural effusions, guides the performance of pleural biopsies when necessary and is more cost-effective under these conditions, and assists in the decision to remove thoracic drainage after talc pleurodesis.With the advent of COVID19, the use of TU has increased for the study of lung involvement. Nowadays it helps in the diagnosis of pneumonias, tumours and interstitial diseases, and its use is becoming more and more widespread in the Pneumology ward.In recent years, TU guided biopsies have been shown to be highly cost-effective, with other advantages such as the absence of radiation and the possibility of being performed at bedside. The use of contrast in ultrasound to increase the cost-effectiveness of these biopsies is very promising.In the study of the mediastinum and peripheral pulmonary nodules, the introduction of echobronchoscopy has brought about a radical change. It is a fully established technique in the study of lung cancer patients. The introduction of elastography may help to further improve its cost-effectiveness.In critically-ill patients, diaphragmatic ultrasound helps in the assessment of withdrawal of mechanical ventilation, and is now an indispensable tool in the management of these patients.

Levels, patterns and risk assessment of PCDD/Fs and dl-PCBs through dietary exposure in the Valencian Region (Spain).

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin like polychlorinated biphenyls (dl-PCBs) levels were measured in representative vegetable oils and animal origin foodstuffs collected in a Total Diet Study carried out in the Valencian Region (Spain). A total amount of 3,300 food samples were collected and grouped into 5 main food groups: vegetable oils, meat and meat products, eggs, milk and dairy products and fish and sea products. The samples were analysed using gas chromatography coupled to high-resolution mass spectrometry (GC-HRMS). The food group which presented the highest concentration in wet weight (ww) for the sum of PCDD/Fs and dl-PCBs was fish and sea products (0.5 pg TEQ g-1 ww), whereas meat and meat products (0.6 pg TEQ g-1 lipid) showed the highest levels expressed in lipid terms. Occurrence data of PCDD/F and dl-PCBs were combined with consumption data to estimate the dietary exposure of adults (>15 years) and children (6-15 years). Finally, the estimated weekly intake (EWI) was calculated using a deterministic approach and considering the food consumption of the population, with fish and sea products being the main food group contributor. Likewise, considering the worst-case scenario (Upper Bound, UB), average EWI were 1.8 and 3.4 pg TEQ kg-1 body weight (bw) week-1 for adults and children, respectively. For children, the average EWI was almost twice above the tolerable weekly intake (TWI) of 2 pg TEQ kg-1 bw week-1 set by EFSA in 2018. In terms of risk characterisation, the overall obtained results showed that 19 % of adults and 43 % of children may exceed the TWI when using UB.

Outpatient Foot-Sparing Surgery Is Safe in Selected Patients with Diabetic Foot Infections.

OBJECTIVE: To determine if outpatient foot-sparing surgery for patients with diabetic foot infections (DFIs) is associated with a higher rate of treatment failure or longer healing time. METHODS: In this prospective observational study, the authors consecutively recruited a cohort of 200 patients with moderate and severe DFIs from the Diabetic Foot Unit of Hospital San Juan de Dios, Caja Costarricense de Seguro Social, San José de Costa Rica, Costa Rica from October 15, 2020 to December 15, 2021. They compared outpatients with those admitted. Cox univariate analysis was performed, with time to treatment failure and time to healing as dependent variables and outpatient management as the independent variable. RESULTS: Seventy-one patients underwent surgery on an outpatient basis (35.5%), and 129 (64.5%) were admitted. Sixty of 111 patients (54.1%) with moderate infections were treated as outpatients versus 11 of 89 (12.4%) of those with severe infections. Twelve (16.9%) of the outpatients and 26 (20.2%) of those admitted presented failure (P = .57). The Cox univariate analysis with time to failure of treatment associated with outpatient management reported a hazard ratio of 1.26 (95% CI, 0.64-2.50; P = .50), and the analysis regarding healing time reported a hazard ratio of 0.91 (95% CI, 0.66-1.25; P = .56). CONCLUSIONS: Foot-sparing surgery on an outpatient basis was safe in more than half the cases of moderate DFIs, especially in patients with osteomyelitis. This approach is not associated with treatment failure or a longer healing time. Patients with severe infections, penetrating injuries, necrosis, or high inflammatory response and those with peripheral arterial disease who require revascularizations should be admitted to the hospital.

Partial characterization of canola (Brassica napus L.) protein isolates as affected by extraction and purification methods.

Canola (Brassica napus L.) meal represents a prominent alternative plant-based source for protein isolation. This work aimed to investigate the combined effect of extraction and purification methods for the production of canola protein isolates (CPIs). CPIs were characterized in terms of process yield, protein recovery, basic composition, amino acid profile, in vitro protein digestibility, techno-functional properties, structural properties, and molecular features. The results showed that the Alk-Uf method enhanced yield (16.23 %) and protein recovery (34.88 %). Meanwhile, the Et-Alk-Uf method exhibited the highest crude protein (89.71 %) and free amino nitrogen (4.34 mg g protein-1) contents. Furthermore, protein digestibility (95.5 %) and protein digestibility corrected amino acid score (1.0) were improved using the Et-Alk-Ac method. Conversely, the amino acid composition, secondary structure, and electrophoretic profiles were generally similar for all CPIs. The Alk-Uf and Et-Alk-Uf methods produced isolates with the highest water solubility (∼39.18 %), water absorption capacity (∼3.86 g water g protein-1), oil absorption capacity (∼2.77 g oil g protein-1), and foaming capacity (∼505.26 %). Finally, the foaming stability (93.75 %) and foaming density (34.38 %) were increased when employing the Alk-Ac method. These findings suggest that, in general, the Alk-Uf and Et-Alk-Uf methods can be used to obtain CPIs with high added value for use in food formulations.

Development and validation of a versatile analytical method for absolute quantification of seven oligosaccharides in human, bovine, and goat milk.

Oligosaccharides are significant in mammalian milk, where they serve as prebiotics that promote the growth of beneficial gut bacteria in infants. Comprehensive research of milk oligosaccharides requires precise and validated analytical methods for compositional studies. To address this need, the focus of our study was to develop and validate an analytical method using UPLC-MS/MS to quantify seven specific oligosaccharides found in mammalian milk. The developed and optimized method has adequate linearity, accuracy, and precision parameters. The detection (LOD) and quantification (LOQ) limits for the seven compounds ranged from 0.0018 to 0.0030 µg/mL and 0.0054-0.0063 µg/mL, respectively. The sample preparation method yielded recovery rates above 90.5 %. Furthermore, no significant matrix effect was observed. The validated method was successfully applied to human, goat, and bovine milk samples, demonstrating its proficiency in identifying variances in the concentration of oligosaccharides across different mammals. This versatile method will allow future research about factors affecting oligosaccharide composition.

Prediction of clinical events by liver stiffness and chronic kidney disease by NAFLD in patients with type-2 diabetes / Predicción de eventos clínicos por elasticidad hepática y enfermedad renal crónica por EHMet en pacientes con diabetes tipo 2

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) is associated with poorer glycemic control and a higher risk of type-2 diabetes (T2D) complications, extrahepatic and cardiovascular disease (CVD). Our study aim was to evaluate the association between NAFLD, T2D complications, and the development of overall clinical events (OCE) (CV, liver-related, and mortality) in patients with T2D. Methods: Prospective single-center study comprising T2D subjects with no history of CVD and non-T2D matched controls. Patients were selected from the Outpatient Diabetes Clinic of Vall d’Hebron Hospital and related primary care centers. Results: 186 diabetics and 57 controls were included. Amongst T2D, 124/186 subjects had NAFLD (66.6%). T2D-NAFLD subjects showed a heavier metabolic burden and higher median liver stiffness (5.6kPa [4.5–7.3] vs 4.8 [4.2–5.8]; p=0.004) compared to non-NAFLD diabetics. During a median follow-up of 5.6 years, 33 (17.7%) T2D patients developed OCE vs 4 (7.0%) controls (p=0.049). No differences were found for OCE between NAFLD and non-NAFLD diabetics (16.9% vs 19.4%; p=0.68). CV was the most reported outcome and only one liver event occurred. NAFLD diabetics showed more often chronic kidney disease (CKD), whereas T2D complications and subclinical CVD rates were similar. A higher liver stiffness, older age, and male gender were independently associated with OCE amongst the entire T2D population and NAFLD diabetics. Conclusions: NAFLD and liver stiffness were associated with CKD and clinical outcomes in diabetics, respectively. A hepatic evaluation is recommended to identify high-risk T2D patients that would benefit from early referral to specialized care. (AU)

Antecedentes y objetivos: La esteatosis hepática metabólica (EHMet) se asocia con un peor control glucémico y un mayor riesgo de complicaciones de la diabetes tipo 2 (DM2), enfermedad extrahepática y cardiovascular (CV). El objetivo fue evaluar la asociación entre EHMet, complicaciones microvasculares y el desarrollo de eventos clínicos globales (ECG) (CV, hepáticos y mortalidad) en diabéticos. Métodos: Estudio unicéntrico prospectivo que incluye diabéticos sin historia de CV y controles sin DM2. Se seleccionaron pacientes de la consulta de Diabetes del Hospital Vall d’Hebron y centros de atención primaria asociados. Resultados: Se incluyeron 186 diabéticos y 57 controles. Entre los diabéticos, 124/186 presentaron EHMet (66,6%). Los pacientes DM2 con EHMet presentaron mayor carga metabólica y una elasticidad hepática superior (5,6kPa [4,5-7,3] vs. 4,8 [4,2-5,8]; p=0,004) a los diabéticos sin EHMet. Durante una mediana de seguimiento de 5,6 años, 33 (17,7%) diabéticos desarrollaron ECG vs. 4 (7,0%) controles (p=0,049). No hubo diferencias en ECG entre diabéticos con y sin EHMet (16,9% vs. 19,4%; p=0,68). El evento más reportado fue CV y solamente se produjo un evento hepático. La enfermedad renal crónica (ERC) fue más frecuente en diabéticos con EHMet, mientras que los ratios de complicaciones microvasculares y enfermedad CV silente fueron similares. El género masculino, una mayor edad y elasticidad hepática se asociaron de forma independiente a ECG para el total de diabéticos y para aquellos con EHMet. Conclusiones: La EHMet y la elasticidad hepática se asociaron a ERC y eventos clínicos en diabéticos. Se recomienda una evaluación hepática para identificar pacientes diabéticos de riesgo que se beneficiarían de una derivación precoz al especialista. (AU)

Agave inulin as a fat replacer in tamales: Physicochemical, nutritional, and sensory attributes.

Tamales are a traditional dish rich in fat and carbohydrates with increasing popularity. The present study aimed to investigate the use of agave inulin powder (AIP) as a potential fat replacer in tamales. The effect of replacing 0%, 33%, 66%, and 100% (w/w) of fat with AIP was evaluated in the physicochemical, sensory, and nutritional features of tamales. The fat content of tamales decreased up to 88% in AIP tamales, whereas total dietary fiber (TDF) increased up to 14%. TDF in AIP tamales had a higher proportion of soluble dietary fiber (SDF). Moreover, results indicated that both insoluble and SDF were formed during the processing of tamales. Fat replacement led to a reduction of up to 26% in the calorie load of tamales. Fourier transform infrared spectroscopy analysis confirmed changes in the absorption bands related to carbohydrates, with increments in peaks associated with inulin (936 and 862 cm-1 ), and inhibition of retrogradation when inulin was included. AIP addition resulted in tamales with lighter color. Fat replacement with AIP affected the texture of tamales increasing their softness, adhesiveness, and cohesiveness. In general, inulin positively affected the hedonic attributes and acceptance of tamales. Interestingly, full-fat tamales had a lower glycemic index and presented higher contents of resistant starch compared to tamales with AIP. Nevertheless, agave inulin may serve as a fat replacer yielding reduced-fat tamales with higher TDF and SDF and yielding a lower calorie load without significantly affecting the sensory acceptability of this traditional meal.

Efficacy of Insulin Titration Driven by SMS in Improving Glycemic Control in People with Type 2 Diabetes.

AIM: To evaluate the efficacy of the self-management of insulin titration based on information received by the Short Message Service (SMS). METHODS: A case-control study including 59 subjects in each arm with 16 weeks of follow-up was performed. The inclusion criteria were: (1) Subjects with type 2 diabetes (T2D) under basal insulin treatment; (2) Suboptimal glycemic control: HbA1c ≥ 7.5% and fasting capillary blood glucose (FCBG) > 140 mg/dL (>3 times per week). Subjects were invited to use an insulin titration service based on SMS feedback aimed at optimizing glycemic control depending on fasting blood glucose levels. Psychological aspects were evaluated in the interventional group by means of validated questionnaires (DDS, HADS and SF-12). RESULTS: The intervention group achieved a lower mean FCBG (126 mg/dL ± 34 vs. 149 mg/dL ± 46, p = 0.001) and lower HbA1c (7.5% ± 1.3 vs. 7.9% ± 0.9, p = 0.021) than the control group. In addition, the intervention group showed a significant improvement in psychological aspects related to Emotional Burden (p = 0.031), Regimen Distress (p < 0.001), Depression (p = 0.049) and Mental Health (p < 0.01). CONCLUSIONS: The SMS-guided titration was effective in terms of improving glucometric parameters in comparison with the standard of care and improved significant psychological aspects-mainly, the stress associated with insulin treatment.

Differences in Foot Infections Secondary to Puncture Wounds or Chronic Ulcers in Diabetes.

We hypothesized that foot infections secondary to a puncture wounds (PWs) have a worse prognosis concerning infection-related mortality, recurrence of the infection, and healing than those secondary to a chronic ulcer. We conducted a prospective study consisting of 200 patients with moderate-to-severe diabetic foot infections. The cohort consisted of 155 men (77.5%) and 45 women (22.5%). The mean age of the patients was 59 years (standard deviation 12.2). Puncture wounds were the cause of the infection in 107 patients (53.5%) and a chronic ulcer was the cause in 93 patients (46.5%). One hundred and eleven patients (55.5%) had moderate and 89 (44.5%) had severe infections. Osteomyelitis was more frequently found in chronic ulcers (71%) than in PWs (44.9%), P < .001. Cox's survival analysis using PWs as an explanatory variable showed no association with infection-related mortality (hazard ratio [HR] 1.06, 95% confidence interval [CI] 0.32-3.46, P = .92), time to recurrence of infection (HR 0.64, 95% CI 0.27-1.51, P = .30), and time to healing (HR 0.81, 95% CI 0.60-1.08, P = .15). More than half of our patients had PWs as the mechanism by which the infection occurred. These patients usually had a lower rate of osteomyelitis but required hospitalization and antibiotic therapy more frequently than patients with infected chronic ulcers. We found no difference in outcomes between the 2 groups.

Impact of Diabetic Foot Multidisciplinary Unit on Incidence of Lower-Extremity Amputations by Diabetic Foot.

BACKGROUND: One of the most devastating complications of diabetes is diabetes-related foot disease (DFD), which is a priority for public health systems. The 2016-2020 Catalonia Health Plan aimed to reduce the incidence of total and major lower-extremity amputations (LEAs) due to DFD by 10% in the population aged 45-74 years. The aim of the present study was to compare the incidence of LEA-DFD 5 years before and after the creation of the Diabetic Foot Multidisciplinary Unit at our Hospital. METHODS: We prospectively collected all cases of LEA-DFD performed at Vall d'Hebron University Hospital from 1 January 2016 to 31 December 2020. Cases of LEA-DFD performed from 1 January 2011 to 31 December 2015 were retrospectively reviewed. The incidence of LEA-DFD between these periods was compared. RESULTS: A total of 457 LEAs due to DFD were performed in 316 patients. We observed a reduction of 27.9% [CI: 23.7-32.1%] in the incidence of total LEA in the 2016-2020 period in comparison with the period 2011-2016 (0.8 ± 0.1 vs. 1.1 ± 0.3 per 10.000 inhabitants/year, p < 0.001), as well as a reduction of 49.3% [CI: 44.6-53.9%] in the incidence of major LEA-DFD (0.15 ± 0.1 vs. 0.30 ± 0.1 per 10.000 inhabitants/year, p < 0.001). CONCLUSIONS: The implementation of a Diabetic Foot Multidisciplinary Unit resulted in a significant reduction in the rate of amputations due to DFD in the population with diabetes in North Barcelona.
