RESUMO
Low socioeconomic status (SES) is associated with a higher risk of fragility fractures, as well as higher mortality in the first year post-fracture. The SES variables that have the greatest impact are educational level, income level, and cohabitation status. Significant disparities exist among racial and ethnic minorities in access to osteoporosis screening and treatment. In Spain, a higher risk of fractures has been described in people with a low income level, residence in rural areas during childhood and low educational level. The Civil War cohort effect is a significant risk factor for hip fracture. There is significant geographic variability in hip fracture care, although the possible impact of socioeconomic factors has not been analyzed. It would be desirable to act on socioeconomic inequalities to improve the prevention and treatment of osteoporotic fractures.
RESUMO
PURPOSE: The aim of the present study, conducted by a working group of the Italian Association of Medical Physics (AIFM), was to define typical z-resolution values for different digital breast tomosynthesis (DBT) models to be used as a reference for quality control (QC). Currently, there are no typical values published in internationally agreed QC protocols. METHODS: To characterize the z-resolution of the DBT models, the full width at half maximum (FWHM) of the artifact spread function (ASF), a technical parameter that quantifies the signal intensity of a detail along reconstructed planes, was analyzed. Five different commercial phantoms, CIRS Model 011, CIRS Model 015, Modular DBT phantom, Pixmam 3-D, and Tomophan, were evaluated on reconstructed DBT images and 82 DBT systems (6 vendors, 9 models) in use at 39 centers in Italy were involved. RESULTS: The ASF was found to be dependent on the detail size, the DBT angular acquisition range, the reconstruction algorithm and applied image processing. In particular, a progressively greater signal spread was observed as the detail size increased and the acquisition angle decreased. However, a clear correlation between signal spread and angular range width was not observed due to the different signal reconstruction and image processing strategies implemented in the algorithms developed by the vendors studied. CONCLUSIONS: The analysis led to the identification of typical z-resolution values for different DBT model-phantom configurations that could be used as a reference during a QC program.

The public health emergency caused by the Covid-19 outbreak in March 2020 encouraged worldwide initiatives to monitor the genetic diversity and features of the SARS-CoV-2 circulating variants, mainly based on the genomic surveillance. However, due to the impossibility to carry out extensive sequencing in resource-limited hospitals, other PCR-based strategies could be applied to efficiently monitor the circulating variants without the need to greatly expand the sequencing capacity. In our case, overpassing the technical limitations inherent to a second level hospital, we were able to characterize the weekly distribution of SARS-CoV-2 by the RT-qPCR amplification patterns visualization, single nucleotide polymorphism genotyping, and sequencing of randomly selected samples. All these molecular approaches allowed us to trace the epidemiology of SARS-CoV-2 viruses circulating in Ibiza and Formentera (Balearic Islands, Spain) during the third to the sixth pandemic waves (January 2021-July 2022), in which three major lineages that were considered as VOCs (Alpha, Delta, and Omicron), and many other non-VOC variants were detected and tracked.

Introduction: The "postural control system" acts through biomechanical strategies and functional neuromuscular adaptations to maintain body balance under static and dynamic conditions. Postural stability and body weight distribution can be affected by external sensory inputs, such as different visual stimuli. Little information is available about the influence of visual receptors on stabilometric and plantar pressure parameters. The aim of this study was to analyze variability, correlations, and changes in these parameters under open- (OE) and closed-eye (CE) conditions. Methods: A total of 31 stabilometric and plantar pressure parameters were acquired in 20 young and healthy adults during baropodometric examination performed in bipedal standing under both visual conditions. Variability of parameters was evaluated via the coefficient of variation, correlation analysis via Pearson's R2, and statistical differences via the Wilcoxon test. Results: High intra-subject repeatability was found for all plantar pressure parameters and CoP-speed (CV < 40%) under OE and CE conditions, while CoP-sway area (CoPsa) and length surface function (LSF) showed larger variability (CV > 50%). Mean and peak pressures at midfoot and total foot loads showed the least number of significant correlations with other parameters under both visual conditions, whereas the arch-index and rearfoot loads showed the largest number of significant correlations. The limb side significantly affected most plantar pressure parameters. A trend of larger LSF and lower CoPsa and mean and peak pressures at the right forefoot was found under the CE condition. Discussion: The present study provides a deeper insight into the associations between postural stability and foot load. Interesting postural adaptations, particularly with respect to different visual stimuli, the effect of the dominant side, and the specific role of the midfoot in balance control were highlighted.
RESUMO
BACKGROUND: Objective mobility measurement of Nepali prosthesis users is lacking. OBJECTIVE: The objective of this study was to cross-culturally adapt, translate and evaluate construct validity of the Prosthetic Limb Users Survey of Mobility (PLUS-M™/Nepali-12 Short Form (SF)) instrument in lower limb prosthesis users residing in Nepal. METHODOLOGY: Two forward translations, review and reconciliation, back translation, expert review, developer review to create the PLUS-M™/Nepali-12SF. Psychometric testing for internal consistency, test-retest reliability and construct validity against the Two-Minute Walk Test (2MWT) and Amputee Mobility Predictor with Prosthesis (AMPPRO) were performed on sixty-six lower limb prosthesis users. FINDINGS: The majority of populations were with transtibial amputation 45 (68%), with transfemoral amputation 15 (23%), with knee disarticulation 5 (7.5%) and with syme's amputation 1 (1.5%). The most common cause of amputation among the population was trauma and the least was tumor. Chronbach's alpha for the PLUS-M™/Nepali-12SF was 0.90, mean T-Score was 52.90, test-retest intraclass correlation coefficient (ICC) was 0.94 (95% confidence interval 0.90-0.96). Construct validity with the 2MWT was good (r = 0.62, p< 0.001) and moderately positive with the AMPPRO (r = 0.57, p< 0.001). CONCLUSION: Our research evidenced that the PLUS-M™/Nepali-12SF had excellent reproducibility. The significance of this work is that it may allow for the measurement of mobility in austere locations of Nepal.
RESUMO
BACKGROUND: The choice of prosthetic socket interface material significantly affects user comfort and satisfaction. The Affordable Ethylene-Vinyl Acetate Roll-On (AERO) liner was created with the aim of improving functionality and streamlining the wearing process for users. OBJECTIVE: The purpose of this study was to comprehensively assess user satisfaction, comfort, and durability of the AERO liner and compare it with the common soft Pe-Lite liner. METHODOLOGY: Fourteen individuals with transtibial amputation participated in this three-month randomized crossover trial study. The Prosthesis Evaluation Questionnaire (PEQ), Expanded Socket Comfort Score (ESCS), and liner thickness measurements were used to comprehensively compare the AERO and Pe-Lite liner. FINDINGS: The AERO liner demonstrated notable improvements in prosthetic comfort and functionality over Pe-Lite liner. After three months use, there was a significant reduction in reported frustration with the AERO liner (p=0.023, r=0.604) in the PEQ subscale. Specific aspects, such as walking with the prosthesis (p=0.030, r=0.601) and odor perception (p=0.024, d=0.579), favored the use of the AERO liner. The expanded socket comfort score (ESCS) revealed significant superiority for the AERO liner "at best" (p=0.04) and "on average" (p=0.02) after one and three months, respectively. Liner thickness analysis showed significant reductions at the mid-patellar tendon location for the AERO liner at one (0.57±0.48) and three months (0.90±0.69, p=0.01) and in the posterior region after three months (0.63±0.64, p=0.05). CONCLUSION: Our study highlights the potential advantages of the AERO liner in enhancing comfort and satisfaction. Yet, durability and thinning of the liner when compared to Pe-Lite may be a concern which may eventually affect socket fit. These findings contribute to ongoing efforts to optimize prosthetic interventions and improve the quality of life of individuals with lower limb prosthesis in resource-limited environments.
RESUMO
BACKGROUND: There is a dearth of literature evaluating the accuracy of Air Displacement Plethysmography (ADP) compared to Dual-energy X-ray Absorptiometry (DXA) for assessing body composition in individuals with lower limb amputations. Validity of ADP in persons with lower limb amputations must be established. OBJECTIVE: The objective of this study was to compare body composition in persons with lower limb amputations using the BOD POD® and DXA. METHODOLOGY: Body composition was performed on eleven lower limb prosthesis users (age 53.2±14.3 years, weight 81.9±22.3kg) using ADP and DXA with and without prosthesis. FINDINGS: Repeated measures ANOVA indicated no significant difference in body composition among and between trials, F(3,8)= 3.36, p= 0.075. There were no significant differences in Body Fat (BF) percentage with and without prostheses on the BOD POD (28.5±15.7% and 33.7±12.1%, respectively) nor the DXA (32.9±10.6% and 32.0±9.9%, respectively). Association between the BOD POD and DXA were greatest when prostheses were not worn compared to when they were worn. Bland-Altman plots indicate agreement between BOD POD® and DXA was greatest while wearing the prosthesis. CONCLUSION: This study is a first to compare total body fat percent between the BOD POD® and DXA in lower limb prosthesis users. BOD POD® report valid indices of BF%. Future work will utilize the BOD POD® in intervention studies for monitoring body composition changes across the continuum of rehabilitation.
RESUMO
Cheeses are able to serve as suitable matrices for supplying probiotics to consumers, enabling appropriate conditions for bacteria to survive gastric transit and reach the gut, where they are assumed to promote beneficial processes. The present study aimed to evaluate the microbiological, immunological, and histological changes in the gut of Salmonella Enteritidis-challenged rats fed goat cheese supplemented with the probiotic strain Lactobacillus rhamnosus EM1107. Thirty male albino Wistar rats were randomly distributed into 5 experimental groups with 6 animals each: negative (NC) and positive (PtC) control groups, control goat cheese (CCh), goat cheese added with L. rhamnosus EM1107 (LrCh), and L. rhamnosus EM1107 only (EM1107). All animals, except NC group were challenged with Salmonella Enteritidis (109 cfu in 1 mL of saline through oral gavage). Microbial composition was assessed with high-throughput 16S rRNA sequencing by means of Illumina MiSeq (Illumina, San Diego, CA). Nuclear factor kappa B (NF-κB) from the animal cecum tissue was determined by real-time PCR and interleukins (TNF-α, IL-1ß, IL-10, and IFN-γ) by means of ELISA. Myeloperoxidase and malondialdehyde levels were determined biochemically. The administration of the L. rhamnosus EM1107 probiotic strain, either as a pure culture or added to a cheese matrix, was able to reduce Salmonella colonization in the intestinal lumen and lessen tissue damage compared with rats from PtC group. In addition, the use of cheese for the probiotic strain delivery (LrCh) was associated with a marked shift in the gut microbiota composition toward the increase of beneficial organisms such as Blautia and Lactobacillus and a reduction in NF-κB expression. These findings support our hypothesis that cheeses might be explored as functional matrices for the efficacious delivery of probiotic strains to consumers.

BACKGROUND & AIMS: In the absence of methodologically sound randomized controlled trials (RCTs), current recommendations for timing and amount of enteral nutrition (EN) in critically ill children are based on observational studies. These studies have associated achievement of a higher EN intake in critically ill children with improved outcome. Inherent to the observational design of these underlying studies, thorough insight in possible confounding factors to correct for is essential. We evaluated the associations between EN intake and 1) patient and daily clinical characteristics and 2) clinical outcomes adjusted for these patient and clinical characteristics during the first week of critical illness with a multivariable mixed model. METHODS: This secondary analysis of the multicentre PEPaNIC RCT investigated a subgroup of critically ill children with daily prospectively recorded gastrointestinal symptoms and EN intake during the first week with multivariable analyses using two-part mixed effect models, including multiple testing corrections using Holm's method. These models combined a mixed-effects logistic regression for the dichotomous outcome EN versus no EN, and a linear mixed-effects model for the patients who received any EN intake. EN intake per patient was expressed as mean daily EN as % of predicted resting energy expenditure (% of EN/REE). Model 1 included 40 fixed effect baseline patient characteristics, and daily parameters of illness severity, feeding, medication and gastrointestinal symptoms. Model 2 included these patient and daily variables as well as clinical outcomes. RESULTS: Complete data were available for 690 children. EN was provided in 503 (73%) patients with a start after a median of 2 (IQR 2-3) days and a median % of EN/REE of 38.8 (IQR 14.1-79.5) over the first week. Multivariable mixed model analyses including all patients showed that admission after gastrointestinal surgery (-49%EN/REE; p = 0.002), gastric feeding (-31% EN/REE; p < 0.001), treatment with inotropic agents (-22%EN/REE; p = 0.026) and large gastric residual volume (-64%EN/REE; p < 0.001) were independently associated with a low mean EN intake. In univariable analysis, low mean EN intake was associated with new acquired infections, hypoglycaemia, duration of PICU and hospital stay and duration of mechanical ventilation. However, after adjustment for confounders, these associations were no longer present, except for low EN and hypoglycaemia (-39%EN/REE; p = 0.018). CONCLUSIONS: Several patient and clinical characteristics during the first week of critical illness were associated with EN intake. No independent associations were found between EN intake and clinical outcomes such as mortality, new acquired infection and duration of stay. These data emphasize the necessity of adequate multivariable adjustment in nutritional support research and the need for future RCTs investigating optimal EN intake.

Nowadays, the use of wild and culture harvest seaweed in food industry is a booming productive sector. In this context, a radiological characterization of five globally common seaweed species that were collected in arrival on Gran Canaria coast was carried out. The studied algae species were Cymopolia barbata, Lobophora variegata, Sargassum vulgare, Dictyota dichotoma and Haliptilon virgatum. Radionuclides analysed by alpha and gamma spectrometry were 238U, 234U, 235U, 210Po, 234Th, 226Ra, 210Pb, 228Th, 224Ra, 40K and 7Be. Activity concentrations, ratios, and concentration factors (CF) were determined for all samples collected. The CF in algae was higher for reactive-particle radionuclides (210Po, 234Th, 228Th and 210Pb) than for conservative ones (40K and the uranium isotopes). 210Po, 228Th and 234Th CF were one or two orders of magnitude higher than those recommended by the IAEA. L. variegata, C. barbata and S. vulgare showed a clear preference for 210Pb and 210Po, for uranium radioisotopes, and for 40K and 234Th, respectively. A dosimetry assessment due to seaweed ingestion showed considerable values of annual committed effective dose for H. virgatum (605⯱â¯19⯵Sv/y), L. variegata (574⯱â¯17⯵Sv/y) and D. dichotoma (540⯱â¯30⯵Sv/y). Hence, this study suggests that an algae radiological characterization is recommended as part of the product valorising process.

BACKGROUND: Transtibial prosthesis socket trim lines have remained fairly consistent over the past decade, and based on methods such as a supracondylar cuff suspension. However, with vacuum suspension methods, trim lines can change. OBJECTIVE: An objective of this technical note was to inform practitioners how to fabricate a socket in a better way. A step-by-step fabrication guide is provided for the prosthetist. METHODS: A unilateral transtibial amputee was selected for this technical note. We provide a detailed description of the different steps of fabrication as well as patient feedback. The fabrication involved fabrication of a vacuum socket using Pre-preg carbon fiber and anti-bacterial Ethylene-Vinyl-Acetate (EVA), as a proximal flexible brim. FINDINGS: The properties of EVA and Pre-preg carbon fiber allow for fabrication of a transtibial socket with a flexible proximal brim. The new design resulted in greater comfort and increased range of motion in the patient studied. The patient subjectively noted enhanced squatting and cycling capabilities while using the updated socket and flexible proximal brim. CONCLUSION: This technical note presented a fabrication guide for a new style of socket and preliminary patient feedback. Clinical studies evaluating functional and biomechanical effects of this new socket design are needed.
RESUMO
OBJECTIVE: No study has evaluated the impact of a multifaceted intervention on the quality of the antibiotics prescribed more than 5 years later. METHODS: A total of 210 general practitioners (GP) from eight different regions of Spain were asked to participate in two registrations of respiratory tract infections (RTI) in 2008, before, and in 2009, just after a multifaceted intervention including prescriber feedback, clinical guidelines, training sessions focused on appropriate antibiotic prescribing, workshop on rapid tests and provision of these tests in the GP consultation. They were all again invited to participate in a similar registration in 2015. A new group of clinicians from the same areas who had never participated in antimicrobial stewardship courses were also invited to participate and acted as controls. RESULTS: The 121 GPs who continued the study (57.6%) and the 117 control GPs registered 22,407 RTIs. The antibiotic most commonly prescribed was amoxicillin and clavulanic acid, prescribed in 1,801 cases (8.1% of the total), followed by amoxicillin (1,372 prescriptions, 6.2%), being lower among GPs just after the intervention. The third leading antibiotic among GPs just after the intervention was penicillin V (127 cases, 3.3%) whereas macrolides ranked third in the other three groups of GPs. CONCLUSIONS: The use of first-line antibiotic for RTIs wanes over time after an intervention, but their utilisation is still significantly greater among intervened clinicians six years later compared to GPs who have never been exposed to any antimicrobial stewardship programmes.

BACKGROUND: To determine the prevalence of abdominal aortic aneurysm (AAA) (arterial diameter ≥30mm), in patients with high or very high cardiovascular risk (CVR) and to evaluate their clinical features. PATIENTS AND METHODS: Observational, cross-sectional and multicentric study conducted in Spanish Internal Medicine Services. We enrolled men with age >55years and women >65years who had a high or very high CVR. RESULTS: The study included 659 patients. The prevalence of AAA was 8% (53 patients). 76.9% were male with a mean age of 71±8.7years. The multivariate analysis showed an association between AAA and age (OR: 1.06; 95%CI: 1.02-1.1; P<.01), male sex (OR: 5.6; 95%CI: 1.6-18.8; P=.01), active smoking (OR: 3.22; 95%CI: 1.16-8.93; P=.024) and peripheral arterial disease (OR: 3.51; 95%CI: 1.73-7.09; P<.01). Diabetes mellitus was an independent protective factor (OR: 0.41; 95%CI: 0.22-0.78; P=.06). Those with subaneurysmal dilatation of the abdominal aorta (diameter 25-29.9mm) presented similar features as patients with AAA. CONCLUSIONS: The prevalence of AAA in patients with high CVR is high. Ultrasound screening can be performed by general practitioners. Men >65years with elevated CVR could benefit, particularly in the presence of active smoking or peripheral arterial disease.
RESUMO
OBJECTIVE: Candida could become the second most frequent cause of nosocomial urinary tract infection. Although Candida albicans is the most important species, others have arisen as emerging pathogens. The aim of this study was to analyze the presence of candiduria in inpatients. METHODS: We performed a retrospective study of Candida isolates from adult inpatient urocultures over five years, gathering and tabulating data on: the species; susceptibility to fluconazole, amphotericin B, and voriconazole (Vitek2, BioMerieux); presence of catheter; hospital department of origin; and patient age and sex. RESULTS: We detected 289 yeast episodes, observing an annual increase: 134 (46.4%) were non-C. albicans yeasts, with 57 (19.7%) being Candida glabrata, 37 (12.8%) Candida tropicalis, 25 (8.6%) Candida parapsilosis, and 10 (3.5%) Candida lusitaniae. Most isolates derived from catheterized (240, 83.0%) and Internal Medicine Department (118, 40.8%) patients, observing an annual increase; 152 (52.6%) isolates were from males, and the mean age was >65 years. Susceptibility to antifungals was >85%. CONCLUSIONS: Inpatient urocultures should include data on the presence of Candida, which is more prevalent in Internal Medicine Department inpatients, in those with urinary catheter, and in over 65-year-olds. Almost half of the isolates were non-C. albicans yeasts, and we recommend complete identification of the species involved.

Elderly patients with underlying urological disease have a greater risk of urinary tract infections due to uncommon pathogens. The disease caused by Aerococcus has been underestimated, but mass spectrometry could be a simple method for identifying this pathogen. In this study, we report 2 cases of urinary tract infection by Aerococcus sanguinicola. A descriptive clinical-microbiological study was conducted on the presence of A. sanguinicola causing urinary tract infections. The presence of A. sanguinicola occurred in elderly patients with previous urological disease and a significant count in urine obtained through bladder catheterisation. Correct identification was achieved through mass spectrometry, and the clinical outcome of administering amoxicillin and cefuroxime was satisfactory. In this study, we also report the pathogenic capacity of A. sanguinicola. When there is a significant number of alpha-haemolytic microorganisms in the urine cultures, A. sanguinicola should be ruled out before reporting a result as urogenital microbiota.
RESUMO
AIM: The current standard of care for locally advanced rectal cancer involves neoadjuvant chemoradiotherapy (CRT) followed by total mesorectal excision. There is a spectrum of response to neoadjuvant therapy; however, the prognostic value of tumour regression grade (TRG) in predicting disease-free survival (DFS) or overall survival (OS) is inconsistent in the literature. METHOD: This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search was undertaken using Ovid MEDLINE, Embase and Google Scholar. Inclusion criteria were Stage II and III locally advanced rectal cancer treated with long-course CRT followed by radical surgery. The aim of the meta-analysis was to assess the prognostic implication of each TRG for rectal cancer following neoadjuvant CRT. Long-term prognosis was assessed. The main outcome measures were DFS and OS. A random effects model was performed to pool the hazard ratio (HR) from all included studies. RESULTS: There were 4875 patients from 17 studies, with 775 (15.9%) attaining a pathological complete response (pCR) and 719 (29.9%) with no response. A significant association with OS was identified from a pooled-estimated HR for pCR (HR = 0.47, P = 0.002) and nonresponding tumours (HR = 2.97; P < 0.001). Previously known tumour characteristics, such as ypN, lymphovascular invasion and perineural invasion, were also significantly associated with DFS and OS, with estimated pooled HRs of 2.2, 1.4 and 2.3, respectively. CONCLUSION: In conclusion, the degree of TRG was of prognostic value in predicting long-term outcomes. The current challenge is the development of a high-validity tests to predict pCR.

BACKGROUND: Transrectal ultrasound-guided prostate biopsy (TUPB) is associated with infectious complications (ICs), which are related to a greater prevalence of ciprofloxacin-resistant bacteria (CRB) in rectal flora. We examined the ICs that occurred in 2 groups: A guided antibiotic prophylaxis (GP) group and an empiric prophylaxis (EP) group. We assessed the financial impact of GP. MATERIAL AND METHODS: The GP group was studied prospectively (June 2013 to July 2014). We collected rectal cultures (RCs) before the TUPB, which were seeded on selective media with ciprofloxacin to determine the presence of CRB. The patients with sensitive bacteria were administered ciprofloxacin. Patients with resistant bacteria were administered GP according to the RC antibiogram. The EP group was studied retrospectively (January 2011 to June 2009). RCs were not performed, and all patients were treated with ciprofloxacin as prophylaxis. The ICs in both groups were recorded during a period no longer than 30 days following TUPB (electronic medical history). RESULTS: Three hundred patients underwent TUPB, 145 underwent GP, and 155 underwent EP. In the GP group, 23 patients (15.86%) presented CRB in the RCs. Only one patient (0.7%) experienced a UTI. In the EP group, 26 patients (16.8%) experienced multiple ICs (including 2 cases of sepsis) (P<.005). The estimated total cost, including the management of the ICs, was 57,076 with EP versus 4802.33 with GP. The average cost per patient with EP was 368.23 versus 33.11 with GP. GP achieved an estimated total savings of 52,273.67. Six patients had to undergo GP to prevent an IC. CONCLUSIONS: GP is associated with a marked decrease in the incidence of ICs caused by CRB and reduced healthcare costs.

Zika virus (ZIKV) cases have been detected across the United States (US) and locally acquired cases have been reported in Florida. Currently, there are no ZIKV screening guidelines and no data on the incidence among organ donors in the US. This retrospective study was conducted at Jackson Memorial-Miami Transplant Institute. Positive ZIKV tests in local deceased organ donors were investigated from 6/2016 to 1/2017. We evaluated demographics and risk factors for ZIKV infection among organ donors and transplant outcomes among recipients of donors with positive ZIKV testing. One hundred forty-two donors were analyzed. Ten percent had traveled to ZIKV-endemic countries and 19% had outdoor occupations. Only 3% had positive ZIKV IGG. None had a positive ZIKV IGM or PCR. ZIKV-positive donors were more likely to have traveled to ZIKV-endemic countries (50% vs. 9%, P = .05). The kidneys from a ZIKV-positive donor were transplanted in our hospital with no 6-month rejection, graft failure, or death in the recipients. Our study demonstrated a low prevalence of ZIKV among deceased donors in our community. Despite local ZIKV transmission, ZIKV was more common in donors who traveled to ZIKV-endemic countries. This cohort demonstrated excellent outcomes in recipients of ZIKV IGG-positive donors. However, larger studies are needed.
