RESUMO

INTRODUCTION: Global warming and the increase in greenhouse gases are a current concern worldwide. The healthcare sector constitutes about 4.4% of all emissions. This study aims to evaluate the knowledge, awareness and attitudes of Therapeutic Radiographers/Radiation Therapists (TR/RTTs) regarding environment-related concepts to inform the development of educational curriculum. METHODS: A validated self-designed survey was distributed to TR/RTTs across Europe by the SAFE EUROPE partners and via social media between October 2021 and February 2022. The survey was divided into six sections: (i) demographics, (ii) knowledge of Circular Economy (CE) and Green Skills (GS), (iii) personal attitudes, (iv) TR/RTTs attitudes, (v) the importance of CE, and (vi) education. Questions consisted of mostly Likert scales complemented with other closed- and open-ended questions. RESULTS: 31%-42% of participants are aware of national and departmental policies in CE and GS concepts. Even though half of the participants considered that they advocate and practice CE, the open questions indicated that participants only focus on waste management, ignoring all the other dimensions of CE in healthcare. Personal attitudes and lifestyles also did not reflect CE. TR/RTTs considered CE practices and GS development essential. However, the suggested academic level at which these skills should be developed was split between High School (44%) and Bachelor's degree (32%). CONCLUSION: It is essential to raise awareness among TR/RTTs about the various dimensions of CE applied to healthcare: "green transportation", "environment-friendly procurement", "hospital building design", "food process optimisation", "water reduction", "energy efficiency", and "waste management". IMPLICATIONS FOR PRACTICE: These GS must be developed by TR/RTTs to decrease their impact on the environment. Their training may need to be lifelong, starting during basic high school education and continuing as healthcare professionals after graduation.

RESUMO

The adoption of intensive production systems, such as compost bedded pack (CB) and freestall (FS), has increased recently in tropical regions, mainly replacing the drylot system (DL). Thus, our objectives were to compare production costs, economic outcomes, and risk of dairy operations in CB, FS, and DL systems. We collected data from 2 181 Brazilian farms over 120 consecutive months; 960 farms (144 CB, 133 FS, and 683 DL) met our selection criteria. All costs were modeled for two animal production categories: milking cows and non-milking animals. We used a regression model that included linear and quadratic parameters, and we added the production system as a fixed variable for all parameters tested with this model. Consultant, year, herd, and herd × system interaction were included in the model as random variables. Further, we simulated annual technical and economic indexes per farm. In addition, we developed a risk analysis to measure the probability of negative profit of the farms based on a 14-year historical series of milk prices. All production costs were affected by the system. Feed, medicine, sundry, and labor costs per farm per year were greater in DL farms when milk yield (MY) was greater than 3 500 L/day. The variables such as milk yield, assets per liter, asset turnover rate, return on assets, operational profit, profit per cow, and per liter of milk variables were greater in CB and FS with high MY (>3 000 L/day). Nonetheless, DL had the greatest economic indexes with a lower MY (<3 000 L/day), lower operating costs, and greater economic outcomes. The risk analysis indicated that the probability of negative profit (risk) was reduced for CB and FS as MY increased, but DL had the lowest risk with low MY levels. In conclusion, we suggest DL as the most attractive system for farms with MY between 150 and 3 000 L of milk/day as the DL had the lowest risk and the greatest profit in this production scale. Despite similar outcomes for CB and FS in most of the farms, the profit per cow ($/year), assets turnover rate (%), risk (%) and expected profit ($/L) analysis indicated that CB could be recommended for farms with MY greater than 3 200 L of milk/day, whereas based on risk (%) and expected profit ($/L), FS would be the most profitable system in dairies producing more than 8 000 L of milk/day per farm.

RESUMO

AIM: To quantify the real-world clinical and cost impact of computed tomography (CT) coronary angiography (CTCA)-derived fractional flow reserve (FFRCT) in the National Health Service (NHS). MATERIALS AND METHODS: Consecutive clinical CTCA examinations from September to December 2018 with ≥1 stenosis of ≥25% underwent FFRCT analysis. The Heart Team reviewed clinical data and CTCA findings, blinded to FFRCT values, and documented hypothetical consensus management. FFRCT results were then unblinded and hypothetical consensus management re-recorded. Diagnostic waiting times for management pathways were estimated. A per-patient cost analysis for diagnostic certainty regarding coronary artery disease (CAD) management was performed using 2014-2020 NHS tariffs for pre- and post-FFRCT pathways. RESULTS: Two hundred and fifty-one CTCAs were performed during the study period. Fifty-seven percent (145/251) had no CAD or stenosis <25%. One study was non-diagnostic. Of the remaining 42% (105/251), two were ineligible for FFRCT and there was a 5% (5/103) failure rate. FFRCT led to a change in hypothetical management in 65% (64/98; p<0.001) patients with a functional imaging test cancelled in 17% (17/98) and a diagnostic angiogram cancelled in 47% (46/98). FFRCT-guided management had a reduced mean time to definitive investigation compared with CTCA alone (28 ± 4 versus 44 ± 4 days; p=0.004). Using the proposed 2020/21 tariff, CTCA + FFRCT for stenosis ≥50% resulted in a diagnostic pathway £44.97 more expensive per patient than usual care without FFRCT. CONCLUSIONS: In the real-world NHS setting, FFRCT-guided management has the potential to rationalise patient management, accelerate diagnostic pathways, and depending on the stenosis severity modelled, may be cost-effective.

RESUMO

AIM: To understand the impact of COVID-19 on radiology trainee experience and well-being. MATERIALS AND METHODS: A questionnaire designed to capture the impact of COVID-19 on radiology training, working patterns, and well-being was sent to all speciality trainees in a regional UK radiology school. The survey was distributed at the beginning of May 2020 and responses collected over 2 weeks. Trainees were questioned about changes that had occurred over a time period starting at the beginning of the COVID-19 pandemic. All survey responses (n=29) were anonymised and the results were subsequently analysed. RESULTS: Sixty-two percent (29 of 47) of trainees within the deanery, who were spread across seven different hospital sites, responded to the questionnaire. All trainees felt that overall radiology workload had decreased in response to COVID-19. Seventy-two percent (21/29) stated that their workload had significantly decreased. Seventy percent (19/27) reported decreased subspecialty experience, and 19% (5/27) reported a complete lack of subspecialty training. Twenty-four percent (7/29) of trainees were redeployed from radiology to clinical ward-based work. Forty-eight percent reported experiencing a worsening in their well-being compared to before the pandemic. CONCLUSION: The first wave of the COVID-19 pandemic had a significant impact on training and well-being. Lessons learnt from this report should help prepare for a second-wave of COVID-19 or future pandemics.

RESUMO

PURPOSE: The state of limited resource settings that Coronavirus (COVID-19) pandemic has created globally should be taken seriously into account especially in healthcare sector. In oncofertility, patients should receive their fertility preservation treatments urgently even in limited resource settings before initiation of anticancer therapy. Therefore, it is very crucial to learn more about oncofertility practice in limited resource settings such as in developing countries that suffer often from shortage of healthcare services provided to young patients with cancer. METHODS: As an extrapolation during the global crisis of COVID-19 pandemic, we surveyed oncofertility centers from 14 developing countries (Egypt, Tunisia, Brazil, Peru, Panama, Mexico, Colombia, Guatemala, Argentina, Chile, Nigeria, South Africa, Saudi Arabia, and India). Survey questionnaire included questions on the availability and degree of utilization of fertility preservation options in case of childhood cancer, breast cancer, and blood cancer. RESULTS: All surveyed centers responded to all questions. Responses and their calculated oncofertility scores showed different domestic standards for oncofertility practice in case of childhood cancer, breast cancer, and blood cancer in the developing countries under limited resource settings. CONCLUSIONS: Medical practice in limited resource settings has become a critical topic especially after the global crisis of COVID-19 pandemic. Understanding the resources necessary to provide oncofertility treatments is important until the current COVID-19 pandemic resolves. Lessons learned will be valuable to future potential worldwide disruptions due to infectious diseases or other global crises.

RESUMO

AIMS: This pilot study aimed to evaluate prospectively the use of inlet radiographs of the hip as an alternative method of the assessment of reduction after the surgical treatment of developmental dysplasia of the hip (DDH). PATIENTS AND METHODS: The children in this study underwent surgery between January 2013 and January 2015. All had inlet radiographs and CT scans post-operatively. Data were analysed by determining inter-observer reliability and intra-observer reproducibility, using the kappa value (K). Differences were settled by discussion between the two observers until a consensus was reached. The sensitivity and specificity of the radiographic and CT results were compared. A total of 26 radiographs were obtained from 23 children, with a mean age of 2.38 years (one to five). RESULTS: Similar high levels of intra- and inter-observer agreement were observed (K = 0.834, 95% confidence interval (CI)). There was a high agreement between the radiographic and CT results (K = 0.834, 5% CI), with excellent sensitivity and a specificity of 95.5%. CONCLUSION: These results suggest that inlet radiographs may be a reliable method of assessing the reduction of the hip after the surgical treatment of DDH.

RESUMO

BACKGROUND AND AIMS: Malnutrition is frequent in heart failure (HF). However, the best tool for evaluating malnutrition in geriatric patients with HF with reduced ejection fraction (HFrEF) is unknown. This study aimed to evaluate the incremental prognostic value of the geriatric nutritional risk index (GNRI) in stable geriatric outpatients with HFrEF compared with a clinical/laboratory prognostic model. METHODS AND RESULTS: A total of 143 outpatients with HFrEF, aged >65 years, a LVEF <40%, and who were stable and on optimal therapy were studied. Follow-up lasted 3 years. The outcome was all-cause death. The GNRI was calculated as follows: [(1.489 × serum albumin (g/L)) + (41.7 × (current body weight/ideal weight)]. The 3-year death rate was 36.4% and 16 (11.2%) patients were at risk of malnutrition (GNRI ≤98). Deceased patients had a lower GNRI (113.6 ± 9.1 vs. 105.6 ± 9.2; p < 0.001) than did survivors. Greater values of the GNRI (hazard ratio = 0.93, 95% confidence interval [CI] = 0.90-0.95; p < 0.001) and GNRI >98 (hazard ratio = 0.29, 95% CI 0.15-0.57; p < 0.001) were associated with better survival. These factors remained significant after adjustment of significant confounders. The GNRI was a better discriminator of death than weight and albumin. Adding the GNRI to the clinical/laboratory predictor survival model significantly increased the c-statistics from 0.93 to 0.95 (p < 0.001) and the chi-square likelihood ratio test from 106.15 to 119.9. CONCLUSION: The risk of malnutrition, as assessed by the GNRI, in stable geriatric outpatients with HFrEF is a strong independent predictor of survival. The GNRI adds significant prognostic information to the clinical/laboratory model.

RESUMO

Most donkey and local horse breeds are vulnerable to extinction as mechanization of agriculture progress throughout the world. The present study analyzed the pedigree and herd records of the donkey Asinina de Miranda breed (RAM), identifying genealogical and human factors that may affect the breed genetic diversity in the future and suggesting suitable strategies to breed preservation, early on the conservation program. The breeding rate was very low, with a ratio of foaling/live animals of 0.23 (178/760). The estimated number of founders and ancestors contributing to the reference population was 128 and 121. The number of founder herds in the reference population was 64, with an effective number of founder herds for the reference population of 7.6. The mean age of herd owners was 65.50 ± 0.884 years, with a negative association among the herd size and owner's age (P<0.001). In contrast, the size of the herd and the ownership of a male were both positively associated (P<0.001) with the herd number of in-born foals. Both the owners' age and the herd location (RAM home region v. dispersal region) were negatively associated with the foaling number (P<0.001). The main identified risk factors were: low breeding rates; low number of males and their unequal contribution to the genetic pool; unequal contribution of the herds to genetic pool; and advanced age of herd owners.

RESUMO

BACKGROUND/OBJECTIVES: Reduced food intake, appetite loss and alteration of ghrelin and PYY(3-36) secretion have been suggested to have a function in the loss of body weight commonly observed after gastrectomy. The objective of this study was to investigate the circulating concentrations of ghrelin and PYY(3-36) and their relationships with food intake, appetite and resting energy expenditure (REE) after gastrectomy plus vagotomy. SUBJECTS/METHODS: Seven patients with total gastrectomy (TG), 14 with partial gastrectomy (PG) and 10 healthy controls were studied. Habitual food intake and REE was assessed; fasting and postprandial plasma total ghrelin, PYY(3-36) concentrations and appetite ratings were determined after ingestion of a liquid test meal. RESULTS: Differently from PG and controls, fasting ghrelin correlated with REE, and a higher energy intake was observed in the TG group. Fasting plasma ghrelin concentrations were lower in TG compared with controls, and no ghrelin response to the meal was observed in either PG or TG. Fasting plasma PYY(3-36) concentrations were not different among the groups. There was an early and exaggerated postprandial rise in PYY(3-36) levels in both PG and TG groups, but not in controls. No effect of ghrelin or PYY(3-36) concentrations was observed on hunger, prospective consumption or fullness ratings. CONCLUSIONS: Total ghrelin and PYY(3-36) do not seem to be involved with appetite or energy intake regulation after gastrectomy plus vagotomy. Ghrelin secreted by sources other than stomach is likely to have a function in the long-term regulation of body weight after TG.

RESUMO

This study aimed to standardize signs and diagnostic criteria of respiratory function in newborn puppies delivered normally or after dystocia and caesarean operation. A total of 48 neonates were allocated into groups: eutocia (n = 20), dystocia (n = 8), caesarean (c)-section (n = 20). Neonatal health was assessed using the Apgar score and body temperature was determined at 0, 5 and 60 min after delivery. Venous blood gases (pO(2) and SO(2)) was measured immediately and 60 min after delivery, and a thoracic radiograph was made between 0 and 5 min of life. The c-section group had significantly lower Apgar scores at birth and 5 min. Hypothermia was present at 5 min in the eutocia and c-section groups, and at 60 min in all groups. The eutocia group had an irregular respiratory pattern in 78% of puppies at birth, 27.7% at 5 min and 21% at 60 min compared with 87.5%, 62.5% and 12.5% of the pups in the dystocia group where there was irregular respiratory rhythm, moderate to intense respiratory sounds with agonic episodes. The c-section group had respiratory alterations in 70%, 45% and 16% of puppies at 0, 5 and 60 min, respectively. Radiographic abnormalities were present in 17% of the pups in the eutocia group, 25% of the pups in the dystocia group and 30% of the pups in the c-section group, respectively. The c-section group had significantly lower SO(2) values at 60 min than at birth. All puppies had hypoxaemia, but a significant decrease was observed in the c-section group. Newborn puppies had tissue hypoxia and irregular respiratory pattern at birth. Caesarean-section puppies had lower vitality; however, all developed satisfactory Apgar scores at 5 min of life, regardless of the obstetric condition.

RESUMO

The chemotherapy of the metastatic breast cancer is characterized by the diversity of the treatment protocols and the utilisation of new expensive molecules posing the double problem of outcomes for the patients and financial effects for the hospitals. This survey describes the different chemotherapy treatments prescribed in the metastatic breast cancer and the direct costs supported by the hospitals according to the patient survival time. A cohort of 371 patients treated for a metastatic breast cancer was followed in three hospitals of the Rhone-Alpes region between 2001 and 2006. The detail of their different antineoplasic treatments, as well as the purchase cost of the drugs and their cost of hospital administration, the cost of the other hospital stays are presented in relation with the survival. The median survival time (35,8 months; CI 95%: [31.7-39.1]) since the first metastasis does not differ significantly according to the hospital. Ninety-three different chemotherapy protocols are observed combining from one to five molecules. Thirty-two different molecules are identified. In first line treatment, there is a significant difference in the use of the new molecules according to hospital (Chi(2) test; P < 10(-3)). The average cost of a chemotherapy treatment is 3,919 euro (+/- 8,069 euro), the higher cost is observed for trastuzumab (23,443 euro). The average time period before the beginning of a new chemotherapy line is 212 days (+/- 237 days) and the mean cost of hospital stay during this period is 3,903 euro (+/- 4,097 euro). If no impact of the chemotherapy treatment strategy is observed on the survival time of the patient, it is the opposite for the hospital treatment cost. These results are asking for a better control system of the authorization procedure of new molecules marketing and the harmonization of the practices.

RESUMO

The objectives of this study were to evaluate the effect of reproductive protocols and reproductive tract score on reproductive performance of dairy heifers and economic outcomes of breeding programs. Holstein heifers (n = 534), 13 +/- 1 mo of age, were randomly assigned to 1 of 4 reproductive protocols. On the day of enrollment (d 0), heifers were palpated per rectum and received a score according to the maturity of their reproductive tract (1 = prepubertal; 2 = peripubertal; and 3 = puber-tal). Estrous detection-control heifers (CON, n = 146) received no treatment and were inseminated on detection of estrus for 28 d. Prostaglandin F(2alpha)-treated heifers (PGED, n = 137) received 1 injection of PGF(2alpha) on d 0 and were inseminated on detection of estrus; heifers not in-seminated by d 14 received a second injection of PGF(2alpha) and were observed for estrus and artificial insemination (AI) for an additional 14 d. Heifers enrolled in the estrous detection-timed AI (EDTAI, n = 140) treatment received a controlled internal drug-release (CIDR) insert on d 0, and 7 d later, the CIDR was removed and all heifers received an injection of PGF(2alpha), heifers received AI on detection of estrus, and those not inseminated by 72 h after PGF(2alpha) received an injection of GnRH concurrent with AI. Heifers in the GnRH-timed AI (GTAI, n = 111) treatment received 1 injection of GnRH on d 0, on d 6 heifers received a CIDR insert and injections of GnRH and PGF(2alpha), on d 13 the CIDR was removed and heifers received an injection of PGF(2alpha), and 48 h later all heifers received an injection of GnRH and AI. Pregnancy was diagnosed at 32 +/- 3 and 62 +/- 3 d after AI. Cost of reproductive protocols and their economic outcomes were calculated for a 28 d period beginning at enrollment. Heifers in the PGED treatment were inseminated at a faster rate than CON heifers. A smaller proportion of prepubertal and peripubertal heifers were inseminated within 14 d of enrollment compared with pubertal heifers. Pregnancy per AI of CON and PGED heifers was greater compared with EDTAI and GTAI heifers. Proportion of GTAI heifers pregnant at the end of the 28-d breeding program was or tended to be smaller compared with PGED and CON heifers, respectively. Heifers in the CON and PGED treatments had the smallest cost per pregnancy followed by heifers in the EDTAI and GTAI treatments, respectively. When different scenarios were evaluated, however, the mean cost per pregnancy was smallest for PGED heifers. Cost per pregnancy generated was greatest for prepubertal heifers, whereas pubertal heifers had the smallest cost per pregnancy generated. Treatment of dairy heifers with PGF(2alpha) every 14 d until insemination and pregnancy results in the best economic outcomes, and screening heifers according to RTS may prove beneficial to identify heifers that may not be pubertal and would have compromised reproductive and economic performance in a breeding program.

RESUMO

BACKGROUND: Since 2001, the French national case mix program is allowed by law to use an enciphering algorithm named "FOIN" to produce a unique anonymous identifier in order to crosslink, within and across hospitals, discharge abstracts from a given patient. This algorithm "thrashes" the person's health insurance number, date of birth and gender. Before using information produced by the case mix program, either for case mix payment or for epidemiology research or for assessing care approaches, the quality of linkage must be evaluated. METHODS: Foin error flags were first assessed in the 2002 Rhône-Alpes regional case mix database. Second, for the two university hospitals of Lyon and Saint-Etienne, double identifiers (two or more Foin identifiers for the same patient) and collisions (a single Foin identifier for at least two patients) were compared with others identifiers: administrative identifier and an anonymous identifier produced by Anonymat software from name, forename and date of birth. Third, Foin error flags are crossed with Foin double identifier or collision mistakes. RESULTS: First, among 1,668,971 hospital discharge abstracts from the regional case mix database, 206,710 (12.4%) had at least one Foin error flag. The most frequent error flag (93026 [5.5%] stays) was due to the lack of the three identifying variables. The greatest number for error flags concerned the stays of newborns (38.5%) and those of public hospitals (17.3%). Second, Foin created a few double identifiers: 1.2% among 137,236 patients from university hospital of Lyon and 0.3% among 39512 patients from university hospital of Saint-Etienne. The collisions concerned 7776 (5.7%) patients from Lyon and 460 (1.2%) from Saint-Etienne. The identifier produced by Anonymat performed better than the one produced by Foin: 99.6% from the two university hospitals. Third, less than 3% of stays without Foin error flag nevertheless had mistakes on Foin when compared with others identifiers. CONCLUSION: The overall assessment is not in favour of a quality threshold using the Foin identifier on a routine basis except in some areas and if certain activities like neonatology are excluded. There are several ways to improve the linkage of health data.

RESUMO

We have recently described the sequence of functional and morphologic changes occurring after a standardized sciatic nerve crush injury. An 8-week post-injury time was used because this end point is the far most used. Unexpectedly, both functional and morphological data revealed that animals had still not recovered to normal pre-injury levels. Therefore, the present study was designed in order to prolong the observation up to 12 weeks. Functional recovery was evaluated using sciatic functional index (SFI), static sciatic index (SSI), extensor postural thrust (EPT), withdrawal reflex latency (WRL) and ankle kinematics. In addition, quantitative morphology was carried out on regenerated nerve fibers. A full functional recovery was predicted by SFI/SSI, EPT and WRL but not all ankle kinematics parameters. Moreover, only two morphological parameters (myelin thickness/axon diameter ratio and fiber/axon diameter ratio) returned to normal values. Data presented in this paper provide a baseline for selecting the adequate end-point and methods of recovery assessment for a rat sciatic nerve crush study and suggest that the combined use of functional and morphological analysis should be recommended in this experimental model.

RESUMO

In a significant number of European countries, the need for providing appropriate treatment for the effluents of small rural communities is still especially relevant. In fact, in countries like Portugal, Spain, and many others, significant amounts of investment will be addressed in the next few years to the construction of small Wastewater Treatment Plants (WWTP). The problems faced when constructing and operating WWTP serving small communities may be relevant when energy and labour costs are relatively high, or when the visual impact on the surrounding areas is especially negative. Sustainable treatment solutions require the selection of appropriate technologies using fewer resources. In this paper, information is presented about sustainability indicators of twenty-one small secondary wastewater treatment plants, including conventional (trickling filters and extended aeration plants) and non-conventional treatment systems (constructed wetlands). The data refer to allocated areas per inhabitant, amounts of concrete per inhabitant, power per inhabitant, and construction and installation costs per inhabitant. The data seem to show that for different reasons, constructed wetlands are promising treatment solutions for application to rural areas in particular because of the relatively low power requirements and relatively low construction costs for served populations below 500 inhabitants.
