RESUMO

This systematic review aimed to provide an overview of test protocols used to measure peak oxygen uptake (VO2peak) in adults with Down syndrome (DS) and to determine how generalisable the outcomes are for the entire population of adults with DS by describing the sample characteristics of these studies and their impact on VO2peak. A literature search (PROSPERO CRD42022309560) was performed (18 July 2023) using the following databases: PubMed, CINAHL, APA PsycINFO, Web of Science, Embase and SPORTDiscus. For articles to be included, they had to be peer-reviewed pubications, reporting VO2peak or VO2max for individuals with DS separately, with a sample of n ≥ 5 and a mean age ≥18 years. Systematic reviews and meta-analyses were excluded but their reference lists were searched for additional papers to include. Studies were evaluated for risk of bias following the guidelines of Kmet et al. The results were summarised with frequency statistics. Forty-three studies were included in this systematic review. Sample sizes of included adults with DS ranged from n = 4-226, with a total of n = 1498 adults with DS being included. Most studies (29/43) used the same standardised maximal exercise treadmill protocol to measure VO2peak in adults with DS, and 33 out of 43 studies used at least one objective criterion to determine a valid maximal effort. Participants were predominantly male, under 40 years old, and overweight or obese. Additionally, the diversity of study samples was lacking or not reported. The most widely used, standardised, maximal exercise test treadmill protocol is recommended for future use in research and practice, including objective criteria to determine valid maximal effort. The current study samples are not representative of the population of adults with DS in terms of sex, age and diverse backgrounds and therefore likely overestimate VO2peak of this population.

RESUMO

1. The following study was conducted to evaluate the tolerability of tall oil fatty acid (TOFA) to broiler chickens, at three graded levels as a nutritional additive in complete feed.2. 256 one-day-old female and male Cobb 500 broiler chickens were assigned to four dietary treatment groups with TOFA at 0 (control), 1.0, 3.0, or 5.0 g/kg within a complete feed for 45 d.3. Birds were weighed individually on days 0, 16, 31 and 45, and the feed intake, bird weight gain, and feed conversion ratio were calculated for the respective starter, grower and finisher phases and over the whole study. On day 45, blood samples were drawn from each bird for haematology and blood chemistry measurements. Two birds per pen were subjected to gross pathological examination and sampling of several tissues for histopathology, including weighing the liver.4. The dietary treatments did not affect zootechnical performance variables or mortality over the whole study period. Bird performance was typical for the breed.5. Haematology, clinical chemistry and histopathology did not reveal any changes associated with dietary TOFA dosing. However, the 5.0 g/kg dose level increased the relative weight of the liver, as a percentage of final body weight, compared to the control group, but there was lack of corresponding histopathology findings.6. In conclusion, the study indicated that oral administration of TOFA for 45 d in feed was well tolerated by the birds at dietary levels of up to 5.0 g/kg.

RESUMO

Undoubtedly, comorbidities complicate long-term HIV management and have significant cost implications for healthcare systems. A better understanding of these comorbidities and underlying causes would allow for a more considered and proactive approach to the long-term management of HIV. This review examines cross-sectional analyses of six European cohort studies (Athens Multicenter AIDS Cohort Study, Aquitaine Cohort, EuroSIDA Cohort study, French claims EGB, German InGef Cohort and the Italian Cohort of Individuals, Naïve for Antiretrovirals), which included individuals with HIV followed over a certain period of time. Based on these cohorts, we examined how comorbidities have changed over time; how they compromise HIV management; and how much of a financial burden they impart. These data also provided a framework to explore the major issues of ageing and HIV and the practical implications of managing such issues in real-life practice.

RESUMO

BACKGROUND: Medicine is a high-status, high-skill occupation which has traditionally provided access to good quality jobs and relatively high salaries. In Ireland, historic underfunding combined with austerity-related cutbacks has negatively impacted job quality to the extent that hospital medical jobs have begun to resemble extreme jobs. Extreme jobs combine components of a good quality job-high pay, high job control, challenging demands, with those of a low-quality job-long working hours, heavy workloads. Deteriorating job quality and the normalisation of extreme working is driving doctor emigration from Ireland and deterring return. METHODS: Semi-structured qualitative interviews were conducted with 40 Irish emigrant doctors in Australia who had emigrated from Ireland since 2008. Interviews were held in July-August 2018. RESULTS: Respondents reflected on their experiences of working in the Irish health system, describing hospital workplaces that were understaffed, overstretched and within which extreme working had become normalised, particularly in relation to long working hours, fast working pace, doing more with less and fighting a climate of negativity. Drawing on Hirschman's work on exit, voice and loyalty (1970), the authors consider doctor emigration as exit and present respondent experiences of voice prior to emigration. Only 14/40 respondent emigrant doctors intend to return to work in Ireland. DISCUSSION: The deterioration in medical job quality and the normalisation of extreme working is a key driver of doctor emigration from Ireland, and deterring return. Irish trained hospital doctors emigrate to access good quality jobs in Australia and are increasingly likely to remain abroad once they have secured them. To improve doctor retention, health systems and employers must mitigate a gainst the emergence of extreme work in healthcare. Employee voice (about working conditions, about patient safety, etc.) should be encouraged and used to inform health system improvement and to mitigate exit.

RESUMO

OBJECTIVES: Five to eight per cent of HIV-positive individuals initiating abacavir (ABC) experience potentially fatal hypersensitivity reactions (HSRs). We sought to describe the proportion of individuals initiating ABC and to describe the incidence and factors associated with HSR among those prescribed ABC. METHODS: We calculated the proportion of EuroSIDA individuals receiving ABC-based combination antiretroviral therapy (cART) among those receiving cART after 1 January 2009. Poisson regression was used to identify demographic, and current clinical and laboratory factors associated with ABC utilization and discontinuation. RESULTS: Between 2009 and 2016, of 10 076 individuals receiving cART, 3472 (34%) had ever received ABC-based cART. Temporal trends of ABC utilization were also heterogeneous, with 28% using ABC in 2009, dropping to 26% in 2010 and increasing to 31% in 2016, and varied across regions and over time. Poisson models showed lower ABC utilization in older individuals, and in those with higher CD4 cell counts, higher cART lines, and prior AIDS. Higher ABC utilization was associated with higher HIV RNA and poor renal function, and was more common in Central-East and Eastern Europe and lowest during 2014. During 779 person-years of follow-up (PYFU) in 2139 individuals starting ABC after 1 January 2009, 113 discontinued ABC within 6 weeks of initiation for any reason [incidence rate (IR) 14.5 (95% confidence interval (CI) 12.1, 17.5) per 100 PYFU], 13 because of reported HSR [IR 0.3 (95% CI 0.1, 1.0) per 100 PYFU] and 35 because of reported HSR/any toxicity [IR 4.5 (95% CI 3.2, 6.3) per 100 PYFU]. There were no factors significantly associated with ABC discontinuation because of reported HSR/any toxicity. CONCLUSIONS: ABC remains commonly used across Europe and the incidence of discontinuation because of reported HSR was low in our study population.

RESUMO

SATB2-associated syndrome (SAS) is a rare disorder caused by alterations in the special AT-rich sequence-binding protein 2 (SATB2). Skeletal abnormalities such as tibial bowing, osteomalacia, osteopenia or osteoporosis have been reported suggesting a higher frequency of skeletal complications in SAS. The optimal timing, necessity, and methodology for routine assessment of bone health in individuals with SAS, however, remain unclear. We report molecular and phenotypic features of 7 individuals with SAS documented to have low bone mineral density (BMD) ascertained by dual-energy X-ray absorptiometry (DXA), often preceded by tibial bowing. The lowest BMD Z-scores ranged -2.3 to -5.6. In 4 individuals, total alkaline phosphatase levels were elevated (2 with elevated bone fraction) around the time of low BMD documentation. A clinically significant fracture history and a diagnosis of pediatric osteoporosis were present in 4 individuals. Pamidronate treatment in 2 children improved BMD. In conclusion, low BMD, fractures, and tibial bowing are relatively common skeletal complications in individuals with SAS. DXA is a useful tool when evaluating a child with SAS suspected to have low BMD and the results might alter clinical management.

RESUMO

BACKGROUND: Dislocated metatarsophalangeal joints from clawed or hammer toes can be a disabling consequence of several conditions. The Cobb-Stainsby forefoot arthroplasty combines partial phalangectomy (Stainsby) with extensor tendon transfer to the metatarsal head (Cobb). We present a retrospective, three surgeon case series of 215 toes in 126 patients. METHODS: Early results and complications were gathered from the medical charts of 126 patients who met the inclusion criteria. Seventy-five patients were contactable by phone with a follow up range of 12-82 months (median follow up 45 months). Primary outcome measures were improvement of pain and function, reduction in plantar callosities and cosmetic improvement of the deformity. RESULTS: Pre-operatively all patients presented with pain and shoe wear problems. Post-operatively seventy-two patients (96%) were satisfied, 72 (96%) reported pain relief, 55 (73%) were happy with toe control, 61 (81%) were pleased with cosmesis and 56 (75%) reported unlimited daily activities. Superficial wound infections were observed in 13 of the 126 patients (10%) and two in 75 patients (2%) developed recurrent clawing. CONCLUSION: Our case series demonstrates improved outcomes over alternatives such as the Weil's osteotomy.

RESUMO

BACKGROUND: Statins are commonly prescribed worldwide and recent evidence suggests that they may increase the risk of herpes zoster (HZ). OBJECTIVES: To quantify the effect of statin exposure on the risk of HZ in the U.K. METHODS: A matched case-control study was conducted using data from U.K. primary care and hospital records. Patients > 18 years with an incident diagnosis of HZ were matched to up to four controls for age, sex and general practice. Patients were included in the statin exposure group if they had ever used a statin, and the daily dosage of the most recent statin prescription and the time since the most recent statin prescription were also recorded. The primary outcome was an incident diagnosis of HZ. Odds ratios (ORs) were estimated from conditional logistic regression and adjusted for potential confounders. RESULTS: A total of 144 959 incident cases of HZ were matched to 549 336 controls. Adjusted analysis suggested strong evidence for an increase in the risk of HZ related to statin exposure (OR 1·13, 95% confidence interval 1·11-1·15). There was also an increased risk when dosages were increased for patients who were currently or had recently been receiving statin treatment (Ptrend < 0·001), and we found an attenuation of the increased risk of HZ in previous statin users as the time since last statin exposure increased (Ptrend < 0·001). CONCLUSIONS: These findings are consistent with the hypothesis that statin therapy leads to an increase in the risk of HZ.

RESUMO

BACKGROUND: With the recognition of the need for research capacity strengthening for advancing health and development, this research capacity article explores the use of technology enhanced learning in the delivery of a collaborative postgraduate blended Master's degree in Malawi. Two research questions are addressed: (i) Can technology enhanced learning be used to develop health research capacity?, and: (ii) How can learning content be designed that is transferrable across different contexts? METHODS: An explanatory sequential mixed methods design was adopted for the evaluation of technology enhanced learning in the Masters programme. A number of online surveys were administered, student participation in online activities monitored and an independent evaluation of the programme conducted. RESULTS: Remote collaboration and engagement are paramount in the design of a blended learning programme and support was needed for selecting the most appropriate technical tools. Internet access proved problematic despite developing the content around low bandwidth availability and training was required for students and teachers/trainers on the tools used. Varying degrees of engagement with the tools used was recorded, and the support of a learning technologist was needed to navigate through challenges faced. CONCLUSION: Capacity can be built in health research through blended learning programmes. In relation to transferability, the support required institutionally for technology enhanced learning needs to be conceptualised differently from support for face-to-face teaching. Additionally, differences in pedagogical approaches and styles between institutions, as well as existing social norms and values around communication, need to be embedded in the content development if the material is to be used beyond the pilot resource-intensive phase of a project.

RESUMO

Orf virus has a worldwide distribution among sheep and goats. The hypersensitivity reaction erythema multiforme (EM) is a known complication of orf infection in humans; however, its occurrence is poorly understood and has not been extensively reviewed. We present two unrelated cases of orf-associated EM, and a review of the literature, highlighting important clinical, epidemiological and immunological aspects of this condition. Orf and its associated complications can occur in rural areas, as well as urban settings, where it is less well-known, through religious or cultural practices involving animal slaughter. Obtaining a history of animal exposures from patients with lesions suspicious for orf and secondary skin eruptions can guide diagnosis and identification of the inciting immune stimulus. Determining the pathophysiology and relative contribution of host and viral factors contributing to EM and other orf-associated hypersensitivity reactions could facilitate the identification of risk factors and inform treatment decisions.

RESUMO

It is evident that there is a nuclear skills shortage within the UK, and logically it can be assumed that the shortfall extends to the radiation protection arena. Plans for nuclear new-build and the decommissioning of existing nuclear sites will require many more people with radiological knowledge and practical competencies. This converts to a nuclear industry requirement in the order of 1000 new recruits per year over at least the next ten years, mainly as new apprentices and graduates. At the same time, the strong demand for persons with radiation protection know-how in the non-nuclear and health care sectors is unlikely to diminish. The task of filling this skills gap is a significant one and it will require a determined effort from many UK stakeholders. The Society for Radiological Protection (SRP) has adopted a strategy in recent years to help address this skills gap. The aim is to engage the interest of secondary school students in the science of radiation and inspire them to follow a career in radiation protection. This paper presents the reasoning behind this strategy and, in an 'outreach case study', describes the establishment of the annual SRP Schools Event. This event is becoming an important addition to the national efforts aimed at increasing the numbers of skilled UK radiation protection professionals over the forthcoming decades.

RESUMO

The matching algorithm in a dynamic marriage market model is described in this first of two companion papers. Iterative Proportional Fitting is used to find a marriage function (an age distribution of new marriages for both sexes), in a stable reference population, that is consistent with the one-sex age distributions of new marriages, and includes age preference. The one-sex age distributions (which are the marginals of the two-sex distribution) are based on the Picrate model, and age preference on a normal distribution, both of which may be adjusted by choice of parameter values. For a population that is perturbed from the reference state, the total number of new marriages is found as the harmonic mean of target totals for men and women obtained by applying reference population marriage rates to the perturbed population. The marriage function uses the age preference function, assumed to be the same for the reference and the perturbed populations, to distribute the total number of new marriages. The marriage function also has an availability factor that varies as the population changes with time, where availability depends on the supply of unmarried men and women. To simplify exposition, only first marriage is treated, and the algorithm is illustrated by application to Zambia. In the second paper, remarriage and dissolution are included.

RESUMO

A dynamic, two-sex, age-structured marriage model is presented. Part 1 focused on first marriage only and described a marriage market matching algorithm. In Part 2 the model is extended to include divorce, widowing, and remarriage. The model produces a self-consistent set of marital states distributed by age and sex in a stable population by means of a gender-symmetric numerical method. The model is compared with empirical data for the case of Zambia. Furthermore, a dynamic marriage function for a changing population is demonstrated in simulations of three hypothetical scenarios of elevated mortality in young to middle adulthood. The marriage model has its primary application to simulation of HIV-AIDS epidemics in African countries.

RESUMO

INTRODUCTION: All national orthopaedic societies advocate the use of patient reported outcome measures (PROMs), but clear guidance on their use is limited. We utilised a collaborative methodology to perform a national audit aiming to assess the perceived variability in PROMs practice in orthopaedic surgery in the United Kingdom. METHODS: A multicentre collaborative audit of practice was performed extracting PROMs data on 21 commonly performed orthopaedic procedures. For each procedure, data were collected for frequency of PROM collection, type of PROM chosen, administration intervals, method and reason for collection. Compliance with national society recommendations was undertaken. RESULTS: Sixty-three trusts enrolled to participate in the study with a completion rate of 60% (38 trusts). The most frequently reported PROMs were those associated with best practice tariffs (83.3% and 80.6% for hip and knee replacements, respectively). Outside incentivised programmes we observed a higher rate of variation in PROMs practice which failed to meet our audit standard. Across all procedures evaluated, 69% (221/318) of respondents to the study used paper as the primary method of PROM collection. CONCLUSIONS: This is the first national audit of PROMs collection in orthopaedics. The integration of PROMs within best practice tariff platforms positively influences the frequency and standardisation of collection. Outside this initiative, PROMS collection is infrequent and highly varied despite the presence of several registries. Because PROMs collection is a recommendation across all procedures using implantable devices, the success of this will depend on the adequacy of funding, resource delivery and the presence of clearer recommendations.

RESUMO

CoverCress (low erucic acid, lower fiber pennycress) is being developed as a cover crop to be planted in the fall after corn and harvested in the spring prior to planting soybeans. Two experiments were conducted to evaluate 2 lines of the whole grain (CCWG-1: natural mutation and mutation breeding; CCWG-2: gene edited) and the whole grain pretreated with the potential palatability agent copper sulfate (CCWG-1-CuSO4; CCWG-2-CuSO4) as an ingredient for broilers. In Experiment 1, CCWG-1-CuSO4 was included in the diet at 0, 4, and 6% for 41 d. Feed intake, body weight gain, feed conversion, processing characteristics, organ weights, serum thyroid, macropathology and histology data were collected. In Experiment 2, broilers were fed diets containing Control, 2% CCWG-1, 4% CCWG-1, 4% CCWG-2, and 4.35% CCWG-1-CuSO4 for 42 d. Feed intake, body weight gain, feed conversion, organ weights, serum thyroid, blood chemistries, macropathology, and histology data were collected. In Experiment 1, feed intake and body weight were diminished with no effect on feed conversion for the birds consuming diets containing CCWG-1-CuSO4. In Experiment 2, feed intake and body weight were lower with no difference in feed conversion in birds fed diets containing greater than 2% CoverCress grain during d 0 to 28. During d 28 to 42 no difference in feed intake, body weight and an improvement in feed conversion was observed in birds fed all of the CoverCress grain products. In both experiments no significant negative effects were observed in processing, liver, kidney, and thyroid weights, T3, T4, blood chemistries, macropathology, and histopathology between the control and any of the CoverCress grain treatments. No difference in performance was observed in birds fed the mutant (4% CCWG-1) and gene-edited (4% CCWG-2) products. Pretreating CoverCress grain with copper sulfate did not have a significant effect on improving palatability. In conclusion, CoverCress grain can be safely fed to broilers when included at a target rate of 4% in diets and with total glucosinolate levels not to exceed 4.9 µmoles g-1.

RESUMO

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic led to hospitals in the UK substituting face-to-face (FtF) clinics with virtual clinic (VC) appointments. We evaluated the use of virtual two-week wait (2-ww) lower gastrointestinal (LGI) clinic appointments, conducted using telephone calls at a district general hospital in England. METHODS: Patients undergoing index outpatient 2-ww LGI clinic assessment between 1 June 2019 and 31 October 2019 (FtF group) and 1 June 2020 and 31 October 2020 (VC group) were identified. Relevant data were obtained using electronic patient records. Compliance with national cancer waiting time targets was assessed. Environmental and financial impact analyses were performed. RESULTS: In total, 1,531 patients were analysed (median age=70, male=852, 55.6%). Of these, 757 (49.4%) were assessed virtually via telephone; the remainder were seen FtF (n=774, 50.6%). Ninety-two (6%, VC=44, FtF=48) patients had malignant pathology and 64 (4.2%) had colorectal cancer (CRC); of these, 46 (71.9%, VC=26, FtF=20) underwent treatment with curative intent. The median waiting times to index appointment, investigation and diagnosis were significantly lower following VC assessment (p<0.001). The cancer detection rates (p=0.749), treatments received (p=0.785) and median time to index treatment for CRC patients (p=0.156) were similar. A significantly higher proportion of patients were seen within two weeks of referral in the VC group (p<0.001). VC appointments saved patients a total of 9,288 miles, 0.7 metric tonnes of CO2 emissions and £7,482.97. Taxpayers saved £80,242.00 from VCs. No formal complaints were received from patients or staff in the VC group. CONCLUSION: Virtual 2-ww LGI clinics were effective, safe and were associated with tangible environmental and financial benefits.

RESUMO

BACKGROUND: Dermatological activity data have been collected for the same region of south-east Scotland (population 1·24 million), approximately every 5 years, since 1981. This has allowed assessment of trends in demand from primary and secondary care, and activity within secondary care dermatology services, assisting planning of dermatological services. OBJECTIVES: To quantify dermatology outpatient workload across the same population to allow comparison with previous studies for trends in practice. METHODS: During November 2010, a standardized proforma was completed for all National Health Service and private practice dermatology outpatient consultations. Demographic data, source and reason for referral, diagnoses, investigations, treatments and disposal were recorded, and comparisons made with five previous studies. RESULTS: A total of 5470 consultations were recorded: 2882 new and 2588 review patients (new to review ratio 1 : 0·9, male to female 1 : 1·3, mean age 49 years, range 1 month to 101 years). Ninety-one per cent of referrals came from primary care and 9% from secondary care. Fifty-eight per cent of referrals were for diagnosis and 32% for hospital management. Diagnostic concordance between referrer and dermatologist ranged from 94% for acne to 14% for melanoma. Benign tumours accounted for 30% of referrals, malignant tumours 13%, dermatitis 13·3%, psoriasis 6·2% and acne/rosacea 5%. The referral rate rose to 23·2/1000 population per annum, with the increase coming mainly from primary care. CONCLUSIONS: Demand for dermatology continues to increase: new referrals have risen by 134% in 30 years, with a 36% increase in the last 5 years, despite corresponding population increases of 5·3% and 3%, respectively.

RESUMO

AIM: Colorectal cancer patients identified with indeterminate pulmonary nodules (IPN) in the absence of other metastasis represent a clinical dilemma. This study aimed to identify characteristics that could predict which nodules truly represented a metastasis in an attempt to optimize therapy and to reduce the number of follow-up chest CT scans performed. METHOD: All patients with colon or rectal cancer who presented between 2004 and 2008 were analysed. Patients with IPN on staging CT were identified from a dedicated prospective database and the medical records analysed and follow up recorded. Patients with obvious metastatic disease were excluded from analysis. Association of location, number and size of the nodules and metastatic disease were the primary end-points for analysis. RESULTS: Nine hundred and eight patients presenting with cancer of the colon or rectum were identified. Thirty-seven (4%) patients were diagnosed with IPN with no obvious metastatic disease on staging CT. At a median follow up of 23 months there were eight (21%) cases where nodules had progressed. No significant association was detected between nodule size and pulmonary metastasis. Half of the patients with four or more nodules showed progression on serial CT imaging suggestive of pulmonary metastasis (χ(2), P ≤ 0.01). CONCLUSION: Colorectal cancer patients with four or more indeterminate pulmonary nodules on preoperative staging CT imaging, even in the absence of metastasis elsewhere, are likely to represent pulmonary metastatic disease. These patients should be followed up with short-term interval CT imaging to enable early detection of progression so that treatment can be tailored appropriately.

RESUMO

BACKGROUND: The COVID-19 pandemic created a unique opportunity to explore the use of Technology Enabled Care Services (TECS), which remains novel for many service providers. This study assesses the factors that affect adaptation to remote monitoring of patients after upper-limb trauma injury. A standardised risk-stratified screening tool is further developed here to support clinical staff in both the determination of appropriate use of TECS and the optimisation of patient care. OBJECTIVES: 1: To explore the patient and injury factors that determine the appropriate use of TECS for patients with upper-limb injury. 2: To use these findings to refine a standardised screening tool for the appropriate choice of follow-up format. METHODS: A retrospective review of patient management was undertaken across three NHS upper-limb trauma units during the first UK COVID-19 lockdown. Data were collected, and themes were analysed across a number of predetermined categories. This was underpinned by a review of contemporary policy guidance and literature. RESULTS: A total of 85% of patients were offered an appropriate format of follow-up; this was defined by the ability to achieve desired patient-clinician goals and lack of complications. Key factors in determining appropriate follow-up included extent of injury, mental health considerations, and the need for face-to-face (F2F) assessment and treatment. CONCLUSION: Study findings demonstrate consistency between units in the factors determining the appropriate use of TECS. The refined screening tool provides a risk-stratified, standardised approach to the choice of follow-up format, F2F or TECS. It is hoped that this will support future clinical decision-making processes to ensure optimal patient care.
