Abstract
After the implementation of the European Space for Higher Education, the contents of the Radiology and Physical Medicine Area that were taught in the Medicine Degree have also been incorporated into the new degrees of Dentistry, Nursing, Physiotherapy, Podiatry, and, to a lesser extent, Pharmacy, Occupational Therapy, Logopedia, and Biomedical Engineering As a whole, the basic concepts of radiology and radiological protection are taught in Murcia in 5 different degrees with a total of 52.5 ECTS credits, participating in the training of 1219 students each academic year. This incorporation in the new degrees has tripled the number of subjects in which undergraduate teaching is taught, and doubled both the number of ECTS credits and the number of undergraduate students to whom it directs its training work. Thus, given the possible creation of new university degrees in the near future (Diagnostic Imaging and Radiotherapy Technicians), it would be necessary to involve a greater number of accredited professionals, from different specialties, and to optimize teaching resources (bibliography, material teacher, clinical cases, etc.,) for its usefulness in the different subjects that share similar contents.

Abstract
BACKGROUND The International Classification of Functioning, Disability, and Health (ICF) is growing in importance in cardiac rehabilitation (CR) as the number of elderly comorbid patients increases. AIM To classify through the ICF framework a group of post-cardiac surgery (CS) and chronic heart failure (CHF) patients undergoing rehabilitation. Then, to compare the two groups and identify possible factors at admission that could affect ICF evaluations at discharge. DESIGN Observational retrospective real-life study. SETTING Two inpatient CR units. POPULATION Consecutive CS and CHF patients admitted for CR (January-December 2019). METHODS Clinical, anthropometric data and functional status at admission and discharge were extracted from patient health records. A set of 26 ICF codes regarding body functions (b) and activities (d) was analyzed to identify: 1) the qualifiers attributed (from 0=no impairment to 4=severe impairment) for each code, 2) the percent distribution of qualifiers (0/1/2/3/4) attributed per patient. We then evaluated changes in both (1) and (2 - defined as ICF Delta%) from admission to discharge. RESULTS All patients (55% males; mean age 73±12 years) showed an improvement post-rehabilitation in the ICF qualifiers attributed (P<0.0001 for all codes). CS patients (N.=150) were less functionally impaired at admission than CHF (N.=194) (P<0.05 for all codes), and at discharge showed greater Delta% in the qualifiers 0/1/2 attributed than CHF (P<0.0001 for b codes; P<0.05 for d codes). Delta% for qualifiers 3 and 4 was similar in the two groups. No impairment at admission (qualifier 0), CS group, and presence/complexity of comorbidities were identified as possible covariates influencing ICF qualifiers at discharge, impacting the rate of both no/mild impairment (ICF% aggregate 0+1 - adjusted R2=0.627; P<0.0001) and moderate impairment (ICF% qualifier 2 - adjusted R2=0.507; P<0.0001). CONCLUSIONS CHF patients showed a worse ICF picture at admission and less improvement at discharge than CS. The presence and complexity of comorbidities negatively influenced the ICF classification at discharge, especially in CHF patients. CLINICAL REHABILITATION IMPACT This study shows the utility of ICF classification in CR as a means for describing, measuring, and comparing patient functioning across the care continuum.

Abstract
PURPOSE Almost 90% of people with Parkinson's disease (PD) develop voice and speech disorders during the course of the disease. Ventilatory dysfunction is one of the main causes. We aimed to evaluate relationships between respiratory impairments and speech/voice changes in PD. METHOD At Day 15 from admission, in consecutive clinically stable PD patients in a neurorehabilitation unit, we collected clinical data as follows: comorbidities, PD severity, motor function and balance, respiratory function at rest (including muscle strength and cough ability), during exercise-induced desaturation and at night, voice function (Voice Handicap Index [VHI] and acoustic analysis [Praat]), speech disorders (Robertson Dysarthria Profile [RDP]), and postural abnormalities. Based on an arbitrary RDP cutoff, two groups with different dysarthria degree were identified-moderate-severe versus no-mild dysarthria-and compared. RESULTS Of 55 patients analyzed (median value Unified Parkinson's Disease Rating Scale Part II 9 and Part III 17), we found significant impairments in inspiratory and expiratory muscle pressure (> 90%, both), exercise tolerance at 6-min walking distance (96%), nocturnal (12.7%) and exercise-induced (21.8%) desaturation, VHI (34%), and Praat Shimmer% (89%). Patients with moderate-severe dysarthria (16% of total sample) had more comorbidities/disabilities and worse respiratory pattern and postural abnormalities (camptocormia) than those with no-mild dysarthria. Moreover, the risk of presenting nocturnal desaturation, reduced peak expiratory flow, and cough ability was about 11, 13, and 8 times higher in the moderate-severe group. CONCLUSIONS Dysarthria and respiratory dysfunction are closely associated in PD patients, particularly nocturnal desaturation and reduced cough ability. In addition, postural condition could be at the base of both respiratory and voice impairments. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.21210944.

Abstract
BACKGROUND: To date little is known about factors affecting walking rehabilitation in Parkinson’s disease (PD) patients. OBJECTIVE: This prospective observational cohort study evaluated the walking distance covered in 6 minutes (6 MWD) before and after conventional rehabilitation and verified which among PD motor disorders was the most important determinant of walking distance in PD patients undergoing rehabilitation. METHODS: Data were collected from 55 PD patients, performing a conventional outpatient motor rehabilitation program. The 6MWD at the end of rehabilitation and gain in 6MWD were the outcome measures. The Unified Parkinson’s Disease Rating Scale, Hoehn and Yahr scale, Nine Hole Peg Test, Grip and Pinch test, ROM wrist motility, and Berg Balance Scale (BBS) were used to assess PD patients at admission and were considered as dependent variables. Backward multiple regression analyses identified the determinants of 6MWD outcomes. RESULTS: The 6MWD was 246.58±115 meters at admission and 286.90±116 at the end of rehabilitation. At end of rehabilitation, the 6MWD was 42.32±47 meters greater than admission (p < 0.001), corresponding to an increase of +17.16% . At the end of rehabilitation, the 6MWD was significantly longer in PD patients with stages 1–3 of the Hoehn and Yahr scale. Berg Balance Scale (β= 0.47, p < 0.001) and right Grip and Pinch at admission (β= 0.36, p = 0.001) were the only determinants of final 6MWD. The R2 value of the model was 0.47 (R2 adjusted 0.45). No variable was a determinant of gain in 6MWD. CONCLUSIONS: The study indicates that balance and generalized muscle strength are important determinants of walking rehabilitation in PD patients, in whom it is essential to maintain high levels of balance and muscle strength for a time as long as possible. These findings suggest planning more intensive rehabilitation treatments in PD patients with low levels of balance and muscle strength.

Abstract
Background The purpose of this article is to summarize the opinions of the surgical oncology leaders from the Global Forum of Cancer Surgeons (GFCS) about the global impact of COVID-19 pandemic on cancer surgery. Methods A panel session (virtual) was held at the annual Society of Surgical Oncology 2021 International Conference on Surgical Cancer Care to address the impact of COVID-19 on cancer surgery globally. Following the virtual meeting, a questionnaire was sent to all the leaders to gather additional opinions. The input obtained from all the leaders was collated and analyzed to understand how cancer surgeons from across the world adapted in real-time to the impact of COVID-19 pandemic. Results The surgical oncology leaders noted that the COVID-19 pandemic led to severe disruptions in surgical cancer care across all domains of clinical care, education, and research. Several new changes/protocols associated with increased costs were implemented to deliver safe care. Leaders also noted that preexisting disparities in care were exacerbated, and the pandemic had a detrimental effect on well-being and financial status. Conclusions The COVID-19 pandemic has led to severe disruptions in surgical cancer care globally. Leaders of the GFCS opined that new strategies need to be implemented to prepare for any future catastrophic events based on the lessons learned from the current events. The GFCS will embark on developing such a roadmap to ensure that surgical cancer care is preserved in the future regardless of any catastrophic global events.

Abstract
OBJECTIVE To compare disability changes measured with the Respiratory ICF Maugeri core set on COPD patients, recovering from acute exacerbation with and without hospitalization, submitted to pulmonary rehabilitation (PR). MATERIALS AND METHODS All COPD inpatients admitted for rehabilitation in 9 Respiratory Units (January-August 2019) were considered eligible. 2066 patients were included (540 discharged from an acute Hospital = Hospital group and 1526 coming from their home = Home group). Healthcare professionals filled, in a digitalized chart, the Respiratory ICF Maugeri core set (26 items), assessing ICF categories at admission and discharge. RESULTS The baseline distribution of the more severe ICF qualifiers was higher in the Hospital group (p < .001) when compared to the Home group. After rehabilitation, all patients -irrespective of hospitalization need- statistically decreased the rate of the higher ICF qualifiers (p < .0001). Hospital group improved more both the rate of qualifiers ≥2 [Δ: -21.32 (22.41) vs -15.48 (17.32), p < .001] and the rate of qualifiers 0-1 [Δ: + 18.38 (24.67) vs 13.25 (19.13), p < .001] than Home group. CONCLUSIONS Disability measured with the "Respiratory ICF Maugeri core set" after PR improves in COPD patients recovering from acute exacerbation irrespective of hospitalization need. Its use an additional outcome remains to be further elucidated.KEY MESSAGESRoutine implementation of an ICF set for chronic respiratory diseases can enhance a patient-centered approach in rehabilitation for different severity conditions.Pulmonary rehabilitation (PR) seems to improve global disability measured with the Respiratory ICF Maugeri core set in COPD patients recovering from acute exacerbation irrespective of hospitalization need, suggesting the use of ICF set as additional PR outcome.The description, through the ICF language, of rehabilitative needs of patients, coming "from-Home" and "from-Hospital" settings, could help staff and instrument organization.

Abstract
The role that oxygen desaturation plays in exercise tolerance and its rehabilitative implications in patients with Parkinson's disease (PD) are unclear. We aimed to test exercise tolerance and oxygen saturation levels both during exercise and at night in PD patients to better define their rehabilitative needs. In clinically stable PD patients, undergoing inpatient rehabilitation, and in "ON" phase, we prospectively assessed clinical data, sleepiness, comorbidities, PD severity (Hoehn&Yahr, HY), motor function (ADLs, UPDRSII and UPDRSIII, Barthel Index, Functional Independence Measure), balance, spirometry, respiratory muscles (MIP/MEP), peak cough expiratory flow (PCEF), continuous night oxygen monitoring, and meters at 6MWT. Of 55 patients analyzed (28 with moderate-severe PD, HY ≥ 2.5), 37% and 23% showed moderate-severe impairment on UPDRSII and UPDRSIII, respectively; 96% had reduced exercise tolerance and severe respiratory muscles impairment (MIP/MEP < 45% pred.); 21.8% showed desaturations during exercise; and 12.7% showed nocturnal desaturations. At multiple regression, low exercise tolerance and low mean nocturnal and exercise-induced saturation correlated with several respiratory and motor function and disability indices (all p < 0.03). Exercise tolerance, exercise-induced desaturations, and nocturnal desaturations were extremely frequent in PD patients and were worse in more severe PD patients. This suggests considering a combined role for motor and respiratory rehabilitation in these patients.

Abstract
BACKGROUND Walking independently after a stroke can be difficult or impossible, and walking reeducation is vital. But the approach used is often arbitrary, relying on the devices available and subjective evaluations by the doctor/physiotherapist. Objective decision making tools could be useful. OBJECTIVES To develop a decision making algorithm able to select for post-stroke patients, based on their motor skills, an appropriate mode of treadmill training (TT), including type of physiotherapist support/supervision required and safety conditions necessary. METHODS We retrospectively analyzed data from 97 post-stroke inpatients admitted to a NeuroRehabilitation unit. Patients attended TT with body weight support (BWSTT group) or without support (FreeTT group), depending on clinical judgment. Patients' sociodemographic and clinical characteristics, including the Cumulative Illness Rating Scale (CIRS) plus measures of walking ability (Functional Ambulation Classification [FAC], total Functional Independence Measure [FIM] and Tinetti Performance-Oriented Mobility Assessment [Tinetti]) and fall risk profile (Morse and Stratify) were retrieved from institutional database. RESULTS No significant differences emerged between the two groups regarding sociodemographic and clinical characteristics. Regarding walking ability, FAC, total FIM and its Motor component and the Tinetti scale differed significantly between groups (for all, p < 0.001). FAC and Tinetti scores were used to elaborate a decision making algorithm classifying patients into 4 risk/safety (RS) classes. As expected, a strong association (Pearson chi-squared, p < 0.0001) was found between RS classes and the initial BWSTT/FreeTT classification. CONCLUSION This decision making algorithm provides an objective tool to direct post-stroke patients, on admission to the rehabilitation facility, to the most appropriate form of TT.

Abstract
AIMS AND OBJECTIVES To document the level of frailty in sub-acute COVID-19 patients recovering from acute respiratory failure and investigate the associations between frailty, assessed by the nurse using the Blaylock Risk Assessment Screening Score (BRASS), and clinical and functional patient characteristics during hospitalisation. BACKGROUND Frailty is a major problem in patients discharged from acute care, but no data are available on the frailty risk in survivors of COVID-19 infection. DESIGN A descriptive cross-sectional study (STROBE checklist). METHODS At admission to sub-acute care in 2020, 236 COVID-19 patients (median age 77 years - interquartile range 68-83) were administered BRASS and classified into 3 levels of frailty risk. The Short Physical Performance Battery (SPPB) was also administered to measure physical function and disability. Differences between BRASS levels and associations between BRASS index and clinical parameters were analysed. RESULTS The median BRASS index was 14.0 (interquartile range 9.0-20.0) denoting intermediate frailty (32.2%, 41.1%, 26.7% of patients exhibited low, intermediate and high frailty, respectively). Significant differences emerged between the BRASS frailty classes regards to sex, comorbidities, history of cognitive deficits, previous mechanical ventilation support and SPPB score. Patients with no comorbidities (14%) exhibited low frailty (BRASS: median 5.5, interquartile range 3.0-12.0). Age ≥65 years, presence of comorbidities, cognitive deficit and SPPB % predicted <50% were significant predictors of high frailty. CONCLUSIONS Most COVID-19 survivors exhibit substantial frailty and require continuing care after discharge from acute care. RELEVANCE TO CLINICAL PRACTICE The BRASS index is a valuable tool for nurses to identify those patients most at risk of frailty, who require a programme of rehabilitation and community reintegration.

Abstract
BACKGROUND Despite therapeutic advances, chronic heart failure (CHF)-related mortality and hospitalization is still unacceptably high. Evidence shows that muscular wasting, sarcopenia, cachexia are independent predictors of mortality and morbidity in CHF and are signs of protein metabolism disarrangement (PMD), which involve all body proteins including circulating one. We postulate that circulating human serum albumin (HSA) could be a marker of PMD and catabolic low-grade inflammation (LGI) in CHF patients. METHODS One hundred sixty-six stable CHF patients (73% males), with optimized therapy referred to cardiac rehabilitation, were retrospectively divided into three groups based on their HSA concentration: ≥3.5 g/dL (normal value), 3.2-3.49 g/dL (low value); ≤3.19 g/dL (severe value). Hematochemical analyses (including circulating proteins and inflammatory markers) and body mass composition (by Bioelectrical Impedance Vector Analysis) were collected and compared. Correlations and multivariate regression were performed. RESULTS Despite being overweight (BMI=27 kg/m2), 75% of patients had reduced HSA (<3.5 g/dL) with suspectable sarcopenia, and 35% of all patients had remarkably lower albumin concentrations (<3.19 g/dL). Hypoalbuminemic patients were disable, older, with reduced muscular proteins, bilirubin and hemoglobin, increased extracellular water and LGI (P<0.01). HSA correlated with all of these parameters (all: P<0.01). Age, LGI, BMI, free-fat Mass, and bilirubin were independent predictors of HSA concentration. All these findings were male-dependent. CONCLUSIONS HSA could be considered a simple marker of PMD and LGI in CHF patients. Evaluation of PMD and gender differences should be considered in new CHF clinical trials.

Abstract
Obstructive sleep apnea (OSA), although a growing healthcare problem and documented risk factor for cardiovascular diseases, is still under-diagnosed in cardiac patients. To investigate the correlation between OSA and echocardiographic parameters of right ventricle diastolic (RVD) dysfunction, in particular trans-tricuspid E-wave deceleration time (EDT), we retrospectively analyzed data of 103 pure (comorbidity-free) OSA patients with comprehensive echocardiographic examination (ETT). Apnea/hypopnea index (AHI), oxygen desaturation index (ODI), mean nighttime oxyhemoglobin saturation (SpO2), time elapsed with SpO2 < 90% (T90) and mean peak desaturation of nocturnal events (Mdes, graded as mild, medium or severe) were compared with echocardiographic parameters. We found RVD dysfunction present in 58.3% of patients. Altered EDT correlated significantly with mean SpO2, T90, and Mdes (p < 0.01, all). Nocturnal desaturators had a significantly worse EDT than non-desaturators (p = 0.027) and a higher risk of prolonged EDT (odds ratio, OR = 2.86). EDT differed significantly according to Mdes severity (p = 0.005) with a higher risk of prolonged EDT in medium/severe vs. mild Mdes (OR = 3.44). EDT detected the presence of RVD dysfunction in 58.3% of our pure OSA patients. It correlated poorly with AHI severity but strongly with nocturnal desaturation severity, independently of age. This ETT marker may be useful for deciding appropriate diagnostic and therapeutic strategies.

Abstract
BACKGROUND Physical exercise combined with occupational therapy (OT) can lead to a global improvement in personal well-being. OBJECTIVE To assess in PD patients: 1) if a rehabilitation program involving OT, Nordic walking (NW) and therapeutic touch (TT) yields motor/non-motor benefits; 2) if the time collocation of OT within the program influences results. METHODS This is a pilot study on 17 PD patients undergoing a 10-week rehabilitation program consisting of OT, NW and TT. Patients were randomized to receive OT in the first [Group 1, n = 8] vs. last five weeks [Group 2, n = 9] of the program. Scales (MMSE, FAB, BDI, UPDRS II and III, PDQ39 and AES-S) and 6MWT, Gait speed and length were assessed at three time-points. RESULTS Thirteen out of 17 patients were analyzed. 6MWT, Gait speed and length improved in time without between-group differences (p < 0.05) as did UPDRII, UPDRSIII, FAB and PDQ39 (p < 0.05). Baseline UPDRS II and III significantly determined Δ6MWT (adjusted R2 = 0.6738) and ΔGAIT speed (R2 = 0.6746) at multiple regression, while ΔGAIT length showed the best regression (adjusted R2 = 0.8247) with impact of age, gender and baseline PDQ39 (ADL and cognition dimensions). CONCLUSIONS Multidisciplinary rehabilitation including OT can improve motor and non-motor conditions in PD patients. The OT time-collocation at beginning or end of the rehabilitation program does not significantly affect results.

Abstract
BACKGROUND Effectiveness of phone surveillance and other communication technologies in the management of neck pain patients have been evaluated previously only at the suspension of the service. AIM To verify whether a phone surveillance program can improve pain, disability, and adherence to home exercises in neck pain patients, and whether the improvement achieved continues to be maintained also after suspension of the support. DESIGN This is a randomized controlled study. SETTING Outpatients of Rehabilitation Unit. POPULATION 84 out of 100 outpatients consecutively randomized (by blocks of four) to Phone group (N.=42, performing a 6-month home-based phone surveillance program) or to Control group (N.=42, with the only recommendation to continue exercising at home without phone surveillance) were considered. The home-based phone surveillance program consisted of 12 scheduled phone calls, each performed every fortnight by a nurse-tutor with expertise in rehabilitation for the first six months of the study. At the end of phone surveillance period, Phone patients were encouraged to continue home exercises for a further 6 months period. METHODS Pain severity (assessed with Pain VAS), disability (Neck Disability Index), and adherence to exercises performed at home (classified as: ≥5 sessions/week, 2-4 sessions/week, occasional or no sessions) were outcome measures. Pain severity and disability were assessed at entry, at 6 and 12 months, while adherence to exercises was self-reported and recorded at 6 and 12 months. Differences between groups were analyzed with χ2 test, Student's t-test or ANOVA. RESULTS At 6 months, Pain VAS (P=0.013) and Neck Disability Index scores (P=0.012) were lower in Phone patients than Controls. At 12 months, Neck Disability Index scores (P=0.026) continued to be lower in Phone patients than Controls. At 6 months, 97.6% of Phone patients and 80.9% of Controls performed rehabilitation at home with a range of 2 to 7 sessions/week; while at 12 months, the respective percentages of Phone and Control patients were 92.9% and 73.8%. Adherence to home exercises was higher in Phone patients than in Controls at 6 (P=0.013) and 12 months (P=0.019). CONCLUSIONS In patients with chronic neck pain, the positive effects of phone surveillance on the neck disability and adherence to home exercises still persist 6 months after the suspension of the support. CLINICAL REHABILITATION IMPACT This knowledge can be useful for physicians to plan home rehabilitation of neck pain patients.

Abstract
The mammalian target of rapamycin (mTOR) signalling pathway regulates fundamental metabolic processes such as inflammation, autophagy and apoptosis, all of which influence cell fate. Recent experimental data suggest that mTOR signalling is involved in many diseases, including lung diseases, but with contrasting data. Overexpression of mTOR and its signalling proteins have been linked to lung cell senescence and development of emphysema, pulmonary hypertension and inflammation. On the other hand, mTOR inhibitors, as rapamycin and/or its derivatives, restore corticosteroid sensitivity in peripheral blood mononuclear cells from chronic obstructive pulmonary disease (COPD) patients, and overexpression of mTOR suppresses cigarette smoke-induced inflammation and emphysema, suggesting that induction of mTOR expression/activity might be useful to treat COPD. This apparent discrepancy is due to complex and heterogenic enzymatic pathway of mTOR. Translation of pre-clinical positive data on the use of mTOR inhibitors to COPD therapy needs a more in-depth knowledge of mTOR signalling.

Abstract
In the present work, growth and digestive enzyme activities of total acid and alkaline proteases, pepsin, trypsin, lipase, and α-amylase, as well as partial characterization of enzyme activity, were studied in diploid and triploid turbot. Growth was similar between both groups. Acid protease activity increased consistently during the experiment, for both diploid (2n) and triploid (3n) fish. The alkaline protease activity was always higher for triploids throughout the experiment. Proteolytic acid activity (pH 2) was generally higher for diploids, at all temperatures tested. Higher activity was at pH 2 and 3 for 2n and 3n fish, respectively. Regarding temperature, acid and alkaline protease activity was higher at 37 °C and 60 °C, respectively, for both groups. The general increase in pancreatic enzymes (trypsin and amylase) before 35 days after hatching (DAH) and posterior decrease until 60 DAH. There was a marked effect on enzyme activity when changing from live prey to pellets (35 DAH), especially on triploids.

Abstract
The objective of this trial was to study the impact of slaughter weight (SW) class: heavy (≥120 kg) or light (<120 kg) on carcass fatness, development of main lean cuts and fat composition in barrows and gilts intended for dry-cured ham and shoulder elaboration. A total of 181 Duroc × (Landrace × Large White) pigs was used, being 94 barrows and 87 gilts. Carcasses from barrows had lower ham compactness but higher shoulder:ham weight ratio than those from gilts. The allometric growth coefficient of ham was higher in gilts whereas those for shoulder, loin and shoulder/ham were higher in barrows. An interaction sex × SW class was found for carcass fatness; the increase of fat thickness was higher in barrows than in gilts in light SW class but higher in gilts than in barrows in heavy SW class. In addition, the allometric growth coefficients for ham, loin and shoulder:ham ratio were higher in light than in heavy pigs. Percentage of rejected carcasses at slaughterhouse, due to lack of fat thickness, was higher for females than for barrows and for light than for heavy pigs. Sex and SW class had no effect on intramuscular fat content. However, more saturation was found in fat (intramuscular) from barrows and in that (subcutaneous) from light pigs. It can be concluded that carcasses from barrows are commercially more suitable than those from gilts and heavy SW might be more interesting when animals are intended for Teruel dry-cured ham and shoulder production.

Abstract
BACKGROUND To date, there are no published data on the use of devices in the management of rotator cuff tear (RCT). AIM The aim of this study was to evaluate the effect of supervised arm cycloergometer training on pain during activities and shoulder functionality in patients with symptomatic full-thickness RCT. DESIGN This is a prospective randomized controlled pilot study. SETTING Outpatients of our Rehabilitation Unit. POPULATION In this pilot study, 40 elderly outpatients (>70 years) with RCT were randomized to two groups: cycloergometer (CYC) vs. control patients. METHODS All patients underwent a common outpatient rehabilitation exercise program consisting of ten 30-min sessions (5 sessions/week). At discharge, CYC patients received 15-min training with an arm cycloergometer and were invited to use the cycloergometer at home 20 min/twice a day. Control patients were invited to continue the standard exercises. During the 6-month study period CYC patients, but not control patients, received educational reinforcement monthly from the nurse of the telemedicine service. Outcomes assessed, between admission (T0) and 6-month follow-up (T6), were: pre to postpain during activities, active and passive ROMsum, ROM-painsum, revised Constant Total Score, and Health Assessment Questionnaire (HAQ). RESULTS At T6, CYC patients showed a significant improvement in all outcome measures with respect to T0 (all: P<0.001). CYC patients showed also significant improvement in passive forward elevation, abduction, and external rotation of shoulder, as well as in active ROMsum and ROM-painsum in all single shoulder movements, and significant improvement in the HAQ items: dressing/grooming, eating, hygiene, reach, and common daily activities. At T6 the CYC group had lower pain during activities (P<0.01) and higher revised constant total score (P<0.01), ROM-painsum (P<0.05) and active ROMsum (P<0.05) than control patients. Home cycloergometer use was inversely associated to pain during activities (P<0.01) and revised Constant Total Score (P<0.01) at T6. CONCLUSIONS A short program of shoulder passive exercises and cuff strengthening exercises followed by regular use of the cycloergometer for 6 months at home can reduce pain and improve shoulder functionality in RCT patients. CLINICAL REHABILITATION IMPACT Our findings indicate that the cycloergometer may be useful in patients with RCT when regularly used at home and suggest use of this mechanical device in rehabilitation programs for these patients.

Abstract
A total of 34 044 official quality assurance reports in dental radiodiagnostic surgery from 16 regions of Spain, compiled from 2002 to 2014, were studied in order to determine the progress of diagnostic reference levels (DRLs) for obtaining diagnostic images under normal conditions for clinical practice in Spanish dental clinics. A DRL of 2.8 mGy was set in 2014, which represents a 41.7 % decrease compared with that of 2002 (4.8 mGy). Over the same time period, the mean dose fell by 55.2 %. However, over the last 3 y, the stabilisation of the mean dose administered to patients has been observed with only a 6.7 % reduction in DRLs, which corresponds to the stabilisation of dental radiodiagnostic surgery on replacing the use of radiographic film with digital imaging systems.

Abstract
The aim of this study was to investigate the fatty acid composition of the outer, inner and subinner subcutaneous backfat layers from Iberian pigs raised under free-range conditions. The pigs were fattened on acorns and grass under free-range conditions from 101 to 155 kg of live weight. Proportions of C16:0, C18:0 and C20:0 were lower in the outer than in the inner layer, while the C12:0, C16:0 and C18:0 contents were higher in the subinner layer than in the inner layer. The outer layer had higher C15:1, C16:1 n-7, C17:1, C18:1 n-7 and similar C16:1 n-9, C18:1 n-9 and C20:1 n-9 proportions than the inner layer, while the subinner layer had lower C17:1, C18:1 n-9, C20:1, similar C15:1, C16:1 n-7, C18:1 n-7 and higher C16:1 n-9 proportions than the inner layer. Only the concentrations of C18:3 n-3, C18:4 n-3 and C20:3 n-3 were lower in subinner than in inner layer. The content of all polyunsaturated fatty acids (PUFA) was higher in the outer than in the inner layer except for the C20:4 n-6 fatty acid. A tendency (P < 0.1) to a higher Σ n-6/Σ n-3 fatty acids ratio was found for the inner and subinner layers than for the outer layer. Significant correlation coefficients were observed between the proportions of C14:0, C16:0, C18:1 n-9, C18:2 n-6, C18:3 n-3 and C20:3 n-9 of the inner layer and subinner layer. The outer layer melting point (MP) was lower than those of the inner and subinner layers, although no difference for MP between inner and subinner layers was observed.

Abstract
The aim of this study was to evaluate if the Biodex Fall Risk Assessment could provide an age-adjusted index useful for classifying patients at "risk of fall."This was a cohort study conducted on 61 chronic patients, in stable conditions, having a history of ataxia, difficulty in walking or loss of balance, and aged >64 years. These patients were coming from home to our Institute undergoing a period of in-hospital standard rehabilitation. Assessment of clinical parameters was performed at entry. Functional scales (Functional Independence Measure [FIM] for motor and cognitive function, Barthel G, Tinetti POMA), and the Biodex Fall Risk Index (FRI) were performed at entry and discharge. The Normalized FRI, obtained adjusting FRI to the reported maximum predictive FRI for the relevant age, identified 2 types of patients: those with a greater risk of fall than expected for that age, labeled Case 1 (Normalized FRI>1); and those with an equal or even lesser risk of fall than expected for that age, labeled Case 0 (Normalized FRI≤1).FRI, Normalized FRI as well as independent variables as age, sex, pathology group, FIM, BarthelG, were considered in a multiple regression analysis to predict the functional improvement (i.e., delta Tinetti Total score) after rehabilitation.Normalized FRI is useful in assessing patients at risk of falls both before and after rehabilitation. At admission, the Normalized FRI evidenced high fall risk in 46% of patients (Case 1) which decreased to 12% after rehabilitation, being greater than age-predicted in 7 patients (Case 1-1) despite the functional improvement observed after the rehabilitation treatment. Normalized FRI evidenced Case 1-1 patients as neurological, "very old" (86% in age-group 75-84 years), and with serious events at 18 to 24 months' follow-up. Normalized FRI, but not FRI, at admission was a predictor of improvement in Tinetti Total scores.The normalized FRI effectively indicated patients at higher risk of fall, in whom health deterioration, falls, or cognitive decline was later documented at follow-up. The normalized FRI could be a standardized measure for identifying frailer patients becoming a further criterium of discharge home and marker of fall risk at home.

Abstract
The presence of boar taint can affect the sensory quality of pork because the "off" odours and flavours can be detected by consumers. The aim of this study was to determine the prevalence of boar taint in pig carcasses from 30 Spanish farms located in different regions of the country. Hot carcass weight and subcutaneous fat thickness means were 79.4±8.19 kg and 18.4±5.09 mm, respectively. Subcutaneous fat samples were classified into different levels according to androstenone and skatole concentrations in adipose tissue measured using GC-MS and HPLC. Androstenone results were: 87.4% of the carcasses below 0.50 μg/g, 7.1% from 0.50 to 1.00 μg/g (medium level), and 5.5% ≥1.00 μg/g (high level). Skatole results were: 88.9% of the carcasses below 0.10 μg/g, 4.5% from 0.10 to 0.20 μg/g (medium level), and 6.6% ≥0.20 μg/g (high level). Given these results, a future online method to classify carcasses according to boar taint is strongly recommended.

Abstract
Cellular responses to chemical cues are at the core of a myriad of fundamental biological processes ranging from embryonic development to cancer metastasis. Most of these biological processes are also influenced by mechanical cues such as the stiffness of the extracellular matrix. How a biological function is influenced by a synergy between chemical concentration and extracellular matrix stiffness is largely unknown, however, because no current strategy enables the integration of both types of cues in a single experiment. Here we present a robust microfluidic device that generates a stable, linear and diffusive chemical gradient over a biocompatible hydrogel with a well-defined stiffness gradient. Device fabrication relies on patterned PSA (Pressure Sensitive Adhesive) stacks that can be implemented with minimal cost and lab equipment. This technique is suitable for long-term observation of cell migration and application of traction force microscopy. We validate our device by testing MDCK cell scattering in response to perpendicular gradients of hepatocyte growth factor (HGF) and substrate stiffness.

Abstract
This study evaluates the effect of vitamin E supplementation source (micellized natural vs. the synthetic form) and dosage (40, 80, or 120 mg/kg) on α-tocopherol concentration in plasma and muscle, antioxidant capacity, and breast meat quality in turkeys. Three hundred female turkeys were randomly selected at an average live weight 63.2 g±0.5 and distributed into 7 groups. One group (control) was fed a standard diet without vitamin E supplementation and the other 6 were given mixed diets supplemented with the natural (d-α-tocopherol) or synthetic (dl-α-tocopheryl acetate) form of vitamin E in 3 dosages (40, 80, or 120 mg/kg). Following 11 wk feeding, results showed that performance parameters were not modified either by source or dosage of vitamin E supplementation to the turkeys. Plasma and muscle α-tocopherol at d 9 of refrigerated storage were higher when turkeys were supplemented with the natural form at higher doses. Losses in the concentration of α-tocopherol in meat between the beginning and the end of the 9 d refrigerated storage were greater in the groups supplemented with the synthetic form of vitamin E compared to those receiving the natural supplementation. The relationship between plasma α-tocopherol and the Trolox equivalent antioxidant capacity followed a different trend depending on the vitamin E source. Intramuscular fat was not significantly affected by the vitamin E source supplementation; however the slope of the linear regression equation was lower for the natural form than for the synthetic form. Turkeys given the natural form had higher C18:1n-9 but lower C15:1, C17:1, C20:5n-3, and C22:6n-3 in breast muscle. Meat samples from turkeys supplemented with natural vitamin E had higher deoxymyoglobin at d 3, 6, and 9 and lower metmyoglobin at d 9 of refrigerated storage than those receiving the synthetic form. Dietary supplementation with medium doses (80 mg/kg) micellized d-α-tocopherol is an interesting feeding strategy for ensuring antioxidant status and improving meat quality.

Abstract
A procedure to quantify intramuscular fat was developed using common inexpensive laboratory equipment. Three homogenization methods of lyophilized muscle samples (Ball-mill, Grinder and Mortar) and two extraction methods (Ball-mill or Vortex) were used in turkey meat and pork. Two-hundred mg of lyophilized and homogenized samples were accurately weighed and mixed with 1.5 mL of dichloromethane-methanol (8:2) and shaken either in a Mixer Mill (MM400, Retsch Technology) or in a Vortex. The final mixture was separated by centrifugation. Solvent was evaporated under a nitrogen stream and lipid content was gravimetrically determined. Besides, it was checked that the fatty acid profile was not altered by the protocol used. Moreover, the analysis of 4 replicas from the same sample showed different variation coefficients (16-29%) for the new procedures proposed over a wide range of IMF content. The combination of Grinder and Vortex methodologies can be proposed as a simple and inexpensive alternative to previous ones.

Abstract
Commercial OP and NP are complex isomer mixtures that can be individually present in the environment, showing different estrogenic potencies. The aims of this study were to establish the estrogenic potency of some AP isomers in comparison to the commercial NP (cNP) mixture in vitro and to investigate in vivo their possible effects during the embryo and larval development of zebrafish. An in vitro estrogen receptor-based recombinant yeast assay was used to test the estrogenicity of specific AP isomers (22-OP, 33-OP, 22-NP, 33-NP and 363-NP) and cNP. The EC₅₀ was in the range of 0.6-7.7 mg/L. Both OP isomers and 363-NP exhibited higher estrogenic activity than cNP. For in vivo experiments, one-day postfertilisation (dpf) embryos were exposed to cNP (50, 250 and 500 μg/L), 363-NP and 33-OP (50 μg/L), 17β-estradiol (100 ng/L) and DMSO (0.01% v/v) for 4weeks. After exposure fish were maintained for 2 weeks in clean water in order to evaluate a possible recovery. Fish of groups exposed to cNP and 363-NP were the last to hatch. Histological alterations were not observed after 7, 28 or 42 dpf. Exposure to 33-OP increased transcriptional levels of erα, vtg and cyp19a1b genes. However, transcriptional response in E2 exposure was observed at later stages and with higher fold induction levels. Exposure to cNP decreased levels of erα whereas increased levels of rxrγ and cyp19a1b. Exposure to 363-NP did not cause changes in transcriptional levels of studied genes. The differences in response of the OP isomer compared to the NP isomer in zebrafish could be related to the rapid decay in concentration of the latter.

INTRODUCTION Zoledronic acid (Z) is a bisphosphonate used in hypercalcaemia-related cancer, in complications for bone metastasis and in postmenopausal osteoporosis and it has been related to osteoradionecrosis, especially when associated with radiation to the head and neck structures. OBJECTIVES To determine the radiosensitization capacity of zoledronic acid in the combined treatment with ionizing radiation (IR) by evaluating its genotoxic and cytotoxic capacities in non-tumoral cells. MATERIALS AND METHODS The genotoxic effect of Z was studied by means of the micronucleus test in cytokinesis-blocked cells of human lymphocytes irradiated before and after a 2 Gy irradiation, while the cytotoxic effect was studied by a cell viability test in the PNT2 cell line before and after exposure to different X-ray doses (0-20 Gy) in four groups (Z alone, radiation alone, Z + IR and IR + Z). RESULTS A dose-dependent and time-dependent cytotoxic effect of Z and IR on PNT2 cells in vitro (p > 0.001) was demonstrated. With the concentrations recommended for humans, the combined treatment had a more pronounced effect than individual treatments (p < 0.001). The effect was synergic (CI < 1), increasing the Z enhancement ratio (2.6) and sensitization factor (56 %); the effect of Z was always greater after IR exposure. In the genotoxic effect, only the administration of Z after irradiation (IR + Z) increased chromosome damage (p < 0.001) and the sensibilization factor (35.7 %). CONCLUSION High concentrations of Z are toxic, but the concentrations recommended for clinical practice in humans give it the characteristics of a radiosensitization agent, whose effect is even greater when administered after IR.

Abstract
We have investigated the blood levels of sub-classes of stem cells (SCs) [mesenchymal stem cells (MSCs), haematopoietic stem cells (HSCs), endothelial progenitor cells/circulating endothelial cells (EPCs/CECs) and tissue-committed stem cells (TCSCs)] in heart failure (HF) patients at different stage of pathology and correlated it with plasmatic levels of proangiogenic cytokines. Peripheral blood level of SCs were analysed in 97 HF patients (24 in NYHA class I, 41 in class II, 17 in class III and 15 in class IV) and in 23 healthy controls. Plasmatic levels of PDGF-BB, bFGF, HGF, vascular endothelial growth factor (VEGF), SDF-1α, TNF-α and NTproBNP were also measured. Compared with healthy individuals, MSC, and in particular the sub-classes CD45−CD34−CD90+, CD45−CD34−CD105+ and CD45−CD34−CXCR4+ were significantly enhanced in NYHA class IV patients (16.8-, 6.4- and 2.7-fold, respectively). Level of CD45−CD34−CD90+CXCR4+cells progressively increased from class II to class IV (fold increases compared with controls: 8.5, 12 and 21.5, respectively). A significant involvement of CXCR4+ subpopulation of HSC (CD45+CD34+CD90+CXCR4+, 1.4 versus 13.3 cells/μl in controls and NYHA class III patients, respectively) and TCSC (CD45−CD34+CXCR4+, 1.5 cells/ μl in controls versus 12.4 and 28.6 cells/μl in NYHA classes II and IV, respectively) were also observed. All tested cytokines were enhanced in HF patients. In particular, for PDGF-BB and SDF-1α we studied specific ligand/receptors pairs. Interestingly, the first one positively correlated with TCSCs expressing PDGFR (r = 0.52, P = 0.001), whereas the second one correlated with TCSCs (r = 0.34, P = 0.005) and with MSCs CD90+ expressing CXCR4 (r = 0.39, P = 0.001). HF is characterized by the increase in the circulating levels of different MSC, HSC, EPC and TCSC subsets. Both the entity and kinetic of this process varied in distinct cell subsets. Specifically, differently from HSCs and EPCs/CECs, MSCs and TCSCs significantly increased with the progression of the disease, suggesting a possible distinct role of these cells in the pathophysiology of HF.

Abstract
Twenty-four castrated male (Duroc × Large Withe × Landrace) with an average weight of 69.4 kg were randomly distributed and located in individual cages and given the experimental diets. Diets were provided ad libitum and were formulated containing three levels of palm oil and hydropalm (hydrogenated palm stearine): 4% and 0% (low saturation), 2% and 2% (moderate saturation) and 0% and 4% (high saturation). Pigs were slaughtered at a local slaughterhouse with an average weight of 129.1 kg. The dietary treatment had no significant influence on growth performances and carcass characteristics. The diet saturation led to an increase of C18:0 and ΣSFA (saturated fatty acids) proportions and to a reduction of C18:1 n-9, C18:2 n-6 and ΣPUFA (polyunsaturated fatty acids) proportions and in subcutaneous backfat outer and inner layers. The dietary treatment affected significantly the melting point of subcutaneous backfat outer layer but had no significant influence on the melting point of the subcutaneous backfat inner layer. However, a linear effect of C18:0 proportion of subcutaneous backfat outer and inner layers on the melting point was observed. Dietary treatment had no significant effect on the main fatty acids pattern of intramuscular neutral and polar lipids from Longissimus dorsi muscle. In neutral lipids of liver a dietary influence (p < 0.05), but not a clear dose--response relationship, was observed for C16:0, C18:1 n-9, ΣSFA and ΣPUFA fatty acids, whereas in polar lipids the dietary treatment had no significant effect on the main fatty acids proportions. No effect of diet saturation was found on rheological properties of fat except for the hardness. The hardness was higher in the pigs that received the diet with 0% of palm oil and 4% hydropalm than in those given the diet with 4% of palm oil and 0% hydropalm.

Abstract
The key aroma components and the lipolysis in a dry cured sausage ‘Sobrassada of Mallorca from black pig’ were studied. Sobrassada was characterized by a fatty acid profile with a high content of monounsaturated fatty acids and by the generation during the curing process of polyunsaturated free fatty acids that were oxidized to generate flavor compounds. Eighty-four different volatile compounds were identified and three of them were for the first time detected in dry sausages (methyl nonanoate, 1-methyl-1H-pyrrole and 2-acetyl pyrrole). Thirty-five different aroma active zones were found. The aroma of sobrassada was not only due to compounds already detected as essential contributors in dry sausages (3-methyl butanoic acid, ethyl 3-methyl butanoate, 2, 3-butanedione and acetic acid) but also to other compounds such as ethyl octanoate, furfural, benzaldehyde, (Z)-2-nonenal, 4-methyl-phenol, delta-hexalactone, heptanoic acid, 2-pentylfuran and 2-acetyl-pyrrole which gave specific aroma notes.

Abstract
The prevalence and mechanisms of antibiotic resistance of Helicobacter pylori have not yet been investigated in Uruguay. The objective of this study was to assess the susceptibility of H. pylori to the most frequently used antibiotics and to determine the mechanism of resistance to clarithromycin. Seventy-nine isolates were obtained from gastric biopsies of 50 adult patients during two periods, 2001 and 2006. The former group enrolled the general population (GP), the latter group Afro-descendant (AD) subjects. The minimum inhibitory concentrations of clarithromycin, amoxicillin, tetracycline, metronidazole, and levofloxacin were determined using the E-test technique. Amplification was achieved through PCR and nucleic acid sequencing to detect mutations in the site of action of clarithromycin in the rRNA gene 23S. No amoxicillin or tetracycline-resistant strains were found. Clarithromycin resistance was found in 12% of the patients overall: 19.4% resistance in AD patients and no resistance in the GP group. This difference was statistically significant. The highest resistance was seen with metronidazole (36%), present in similar proportions in the two groups: 36.8% (GP) and 35.5% (AD). One GP patient and one AD patient had levofloxacin-resistant strains. Sequencing analysis of gene 23S rRNA showed that only mutation in position 2143 was presented in all clarithromycin-resistant strains.

Abstract
This experiment was conducted to study the effect of vitamin A concentration in the diet on fatty acid composition in pigs. One-hundred and twenty eight Duroc × (Large White × Landrace) castrated male pigs were used. Pigs were randomly distributed and located in cages of four pigs each to the following treatment: vitamin A-enriched diet (100,000IU/kg) (n=16) and control diet with a basal level (7500IU/kg) (n=16). The pigs were slaughtered at an average weight of 125.9kg. No effect of diet vitamin A level on performance, carcass traits and intramuscular fat percentage was observed. The retinol concentration in subcutaneous backfat and retinol and retinol palmitate contents in liver were higher in the pigs that were given the vitamin A enriched diet than in those receiving the control diet. However the vitamin A supplementation did not increase the retinol content in the muscle. Pigs receiving the vitamin A enriched diet showed a higher C16:0 and ∑SFA proportions in the outer layer and C18:0 and ∑SFA proportions in the inner layer. Moreover, the diet rich in vitamin A led to a reduction of C18:1 n-9 and ∑MUFA proportions in subcutaneous backfat inner layer. Dietary vitamin A concentration had not influence on main fatty acids composition of intramuscular lipids. Dietary vitamin A enrichment lead to a higher C16:0, ∑SFA concentration in liver lipids.

Abstract
Infection with Helicobacter pylori has been shown to be at the origin of various gastric pathologies. However, it has not yet been established whether the etiology of such diseases, particularly of gastric cancer, is related to the production of free radicals or to mutagenesis. The aim of this study was to determine whether a six-month infection with Helicobacter pylori increased the amount of lipid peroxidation, nitric oxide, and DNA damage in Mongolian gerbils (Meriones unguiculatus). H. pylori was characterized genotypically and administered orally to the animals. Four tests were applied to identify the presence of bacteria at one, two, four, and six months after the inoculation, namely, isolation and identification in culture, the urease test, the ELISA assay, and immunohistochemical staining of gastric biopsies. The infection was considered to be successful when three of the above-mentioned tests were positive. The infection occurred in 30% of the animals in the first month after the H. pylori inoculation and in 60-70% of the animals in the later stages. Levels of malondialdehyde, nitric oxide, and DNA damage (using the "comet" assay) were determined in the gastric tissue of the animals at one, two, four, and six months. We found statistically significant increases in malondialdehyde and nitric oxide levels from the second month on. The comet assay in animals infected with H. pylori showed a significant increase in the mean tail length throughout the observation period. We conclude that our results support the assumption that oxidative damage and DNA breakage produced by the infection with H. pylori are some of the initial alterations occurring in the development of gastric diseases.

Abstract
The angiotensin-converting enzyme (ACE) has two natural substrates and two catalytic domains: one cleaving angiotensin I and one inactivating bradykinin. The aim of this study was to investigate the comparative binding affinity of ACE inhibitors for the two binding sites of human endothelial ACE. In vitro binding assays were performed to test the ability of bradykinin, angiotensin I, or various ACE inhibitors (enalaprilat, perindoprilat, quinaprilat, ramiprilat, and trandolaprilat) to displace a saturating concentration of [(125)I]351A, a radiolabeled lisinopril analogue, from ACE binding sites. The calculated IC(50) values for the ACE inhibitors were in the nanomolar range, while those for the natural substrates were in the micromolar range. The bradykinin/angiotensin I selectivity ratios calculated from double displacement experiments were: perindoprilat, 1.44; ramiprilat, 1.16; quinaprilat, 1.09; trandolaprilat, 1.08; enalaprilat, 1.00. The ACE inhibitors generally had higher affinity for the bradykinin than the angiotensin I binding sites, supporting the idea that these agents are primarily inhibitors of bradykinin degradation, and secondarily inhibitors of angiotensin II production. Perindoprilat had the highest selectivity for bradykinin versus angiotensin I binding sites, and enalaprilat has the lowest. These results indicate that there are differences in the affinity of ACE inhibitors toward sites for bradykinin degradation, which could lead to differences in efficacy in cardiovascular disease.
