RESUMO

Cognitive impairment is a common and disruptive outcome for stroke survivors, which is recognized to be notoriously difficult to treat. Previously, we have shown that low oxygen post-conditioning (LOPC) improves motor function and limits secondary neuronal loss in the thalamus after experimental stroke. There is also emerging evidence that LOPC may improve cognitive function post-stroke. In the current study we aimed to explore how exposure to LOPC may improve cognition post-stroke. Experimental stroke was induced using photothrombotic occlusion in adult, male C57BL/6 mice. At 72 h post-stroke animals were randomly assigned to either normal atmospheric air or to one of two low oxygen (11% O2) exposure groups (either 8 or 24 h/day for 14 days). Cognition was assessed during the treatment phase using a touchscreen based paired-associate learning assessment. At the end of treatment (17 days post-stroke) mice were euthanized and tissue was collected for subsequent histology and biochemical analysis. LOPC (both 8 and 24 h) enhanced learning and memory in the 2nd week post-stroke when compared with stroke animals exposed to atmospheric air. Additionally we observed LOPC was associated with lower levels of neuronal loss, the restoration of several vascular deficits, as well as a reduction in the severity of the amyloid-beta (Aß) burden. These findings provide further insight into the pro-cognitive benefits of LOPC.

RESUMO

There is an urgent and recognized need for an interprofessional collaborative approach to support global action in addressing antimicrobial resistance (AMR). Antimicrobial stewardship (AMS) refers to systematic approaches for antimicrobial optimization within healthcare organizations. In areas with high antimicrobial utilization such as intensive care units (ICUs), specific roles for nurses in AMS are not clearly defined. This review aimed to identify and to critically evaluate primary studies that examined knowledge, perspectives and experiences of nurses associated with antimicrobial use and optimization in ICUs. A systematic search of Medline, CINAHL, PsychINFO, EMBASE, PubMed, SCOPUS, Cochrane Library and Web of Science databases for primary studies published from 1st January 2000 to 20th March 2020 was performed. A convergent synthesis design was used to synthesize quantitative and qualitative data. Of the 898 studies initially screened, 26 were included. Most (18/26) studies were quantitative. All qualitative studies (6/26) were of high methodological quality. Studies where interventions were used (10/26) identified significant potential for ICU nurses to reduce antimicrobial use, time-to-antibiotic administration, and error rates. Barriers to nursing engagement included knowledge deficits in antimicrobial use, interprofessional dissonance and the culture of deference to physicians. Enhancing education, technology utilization, strong nursing leadership and robust organizational structures that support nurses were perceived as enablers to strengthen their roles in optimizing antimicrobial use. This review showed that nursing initiatives have significant potential to strengthen antimicrobial optimization in ICUs. Barriers and enablers to active engagement were identified.

RESUMO

Vascular malformations are being increasingly identified with associated syndromes caused by sporadically occurring, non-heritable somatic mutations. CLOVES syndrome is a newly recognized constellation of congenital lipomatous overgrowth with vascular malformations, epidermal nevi, and skeletal/spinal anomalies. We report the unique case of CLOVES syndrome diagnosed in a pediatric patient five years after the initial surgical resection of an extensive venolymphatic malformation involving the chest, neck, axilla, and posterior trunk. The lipomatous overgrowths were successfully resected, and subsequent genetic analysis revealed a heterozygous, pathogenic, somatic variant in the PIK3CA gene, confirming our suspicion of CLOVES syndrome.

RESUMO

OBJECTIVES: Here we examine the association between shift work sleep disorder (SWSD) and erectile dysfunction (ED) in shift workers. METHODS: Men presenting to a single andrology clinic between January 2014 and July 2017 completed validated questionnaires: International Index of Erectile Function (IIEF), Patient Health Questionnaire-9 (PHQ-9), and the nonvalidated SWSD Questionnaire. Men were also asked about shift work schedule, comorbidities, phosphodiesterase 5 (PDE5) inhibitor use, and testosterone use. Serum total testosterone values were determined for each visit. Linear regression was performed controlling for testosterone use, testosterone levels, PDE5 inhibitor use, age, and comorbidities to determine the effect of SWSD on ED as assessed using the IIEF. RESULTS: Of the 754 men completing questionnaires, 204 reported nonstandard shift work (begins before 7 am or after 6 pm, regularly extends out of that frame, or rotates frequently) and 48 were found to have SWSD using a screening questionnaire. Nonstandard shift work alone did not result in worse IIEF-EF scores (P = .31), but those who worked nonstandard shifts and had SWSD demonstrated IIEF-EF scores 2.8 points lower than men without SWSD (P < .01). When assessing for the type of shift work performed, men who worked night shifts had IIEF-EF scores 7.6 points lower than men who worked during the day or evening (P < .01). Testosterone use improved IIEF-EF scores for men with SWSD by 2.9 points, ameliorating the effect of SWSD on ED. However, baseline testosterone levels were not associated with worse erectile function in this cohort. CONCLUSION: Men with SWSD have worse erectile function, with men who work night shifts having even poorer erectile function. These findings suggest that circadian rhythm disturbance may significantly impact erectile function. While testosterone therapy may partly reverse the effects of SWSD, shift work is a potential risk factor for ED and should be assessed for as part of the evaluation of men with ED.

RESUMO

Developing a biomaterial that can promote osteoblastic differentiation, thereby reducing the needs of exogenous osteogenic factors for large bone repair, has been a significant and long-term technical hurdle. In this study, we developed an innovative nanoclay (nanosilicate, NS)-functionalized 3D gelatin nanofibrous scaffold (GF/NS) through a thermally induced phase separation method together with the particle leaching technique (TIPS&P). In addition to the significantly higher mechanical strength, the composite scaffolds (GF/NS) demonstrated a significantly stronger ability to promote the osteogenic differentiation of human mesenchymal stem cells (hMSCs) in vitro compared to the GF scaffold. Our data further revealed that this intriguing pro-osteoblastic functionality was largely because of the unique features of NS, particularly, the strong binding ability to pro-osteoblastic factors (e.g., BMP2) as well as the intrinsic osteoinductivity of its bioactive degradation products. Most importantly, our in vivo studies indicated that GF/NS scaffolds significantly improved low-dose BMP2-induced ectopic bone regeneration in mice.

RESUMO

OBJECTIVE: To examine the association between shift work sleep disorder (SWSD), a primary circadian rhythm disorder characterized by excessive day-time sleepiness associated with shift work, and hypogonadal symptoms in shift workers. METHODS: Men presenting to an andrology clinic between July 2014 and June 2017 completed questionnaires assessing shift work schedule, SWSD risk, and hypogonadal symptoms ([quantitative] Androgen Deficiency in the Aging Male [qADAM, ADAM]). The impact of nonstandard shift work and SWSD on responses to qADAM and ADAM was assessed using ANOVA and linear regression. RESULTS: About 24.1% (619/2571) of men worked nonstandard shifts. Of those, 196 (31.7%) were considered to have SWSD. Controlling for age, comorbidities, and testosterone (T) levels, nonstandard shift workers had qADAM scores 1.12 points lower than day-time workers (P <.01). Subgroup analysis of nonstandard shift workers showed that those with SWSD had qADAM scores 5.47 points lower than men without SWSD (P <.01). In this same subgroup analysis, SWSD was independently associated with lower T levels (mean decrease 100.4 ng/dL, P <.01) when controlling for age, comorbidities, and prior T supplementation. CONCLUSION: Nonstandard shift workers with SWSD have even worse hypogonadal symptoms and lower T levels than day-time workers and nonstandard shift workers without SWSD. This suggests that poor sleep habits, as identified by SWSD, may contribute to the more severe hypogonadal symptoms seen in nonstandard shift workers.

RESUMO

OBJECTIVES: Significant antimicrobial overuse persists worldwide, despite overwhelming evidence of antimicrobial resistance and knowledge that optimization of antimicrobial use will slow the development of resistance. It is critical to understand why this occurs. This study aims to consider the social influences on antimicrobial use within hospitals in Australia, via an in-depth, multisite analysis. METHODS: We used a qualitative multisite design, involving 222 individual semi-structured interviews and thematic analysis. Participants (85 doctors, 79 nurses, 31 pharmacists and 27 hospital managers) were recruited from five hospitals in Australia, including four public hospitals (two metropolitan, one regional and one remote) and one private hospital. RESULTS: Analysis of the interviews identified social relationships and institutional structures that may have a strong influence on antimicrobial use, which must be addressed concurrently. (i) Social relationships that exist across settings: these include the influence of personal risk, hierarchies, inter- and intraprofessional dynamics and sense of futility in making a difference long term in relation to antimicrobial resistance. (ii) Institutional structures that offer context-specific influences: these include patient population factors (including socioeconomic factors, geographical isolation and local infection patterns), proximity and resource issues. CONCLUSIONS: The success of antimicrobial optimization rests on adequate awareness and incorporation of multilevel influences. Analysis of the problem has tended to emphasize individual 'behaviour improvement' in prescribing rather than incorporating the problem of overuse as inherently multidimensional and necessarily incorporating personal, interpersonal and institutional variables. A paradigm shift is urgently needed to incorporate these critical factors in antimicrobial optimization strategies.

RESUMO

Penile duplex ultrasound (PDU), combined with pharmacologic stimulation of erection, is the gold standard for the evaluation of multiple penile conditions. A 30-question electronic survey was distributed to members of the International Society for Sexual Medicine (ISSM). The survey assessed the variability in current PDU practice patterns, technique, and interpretation. Chi-square test was used to determine the association between categorical variables. Approximately 9.5% of all 1996 current ISSM members completed the survey. Almost 80% of members surveyed reported using PDU, with more North American practitioners utilizing PDU than their European counterparts (94% vs 69%, p < 0.01). Approximately 62% of PDU studies were performed by a urologist and more than 76% were interpreted by a urologist. Although almost 90% of practitioners reported using their own protocol, extreme variation in the technique existed among respondents. Over ten different pharmacologic mixtures were used to generate erections, and 17% of respondents did not repeat dosing for insufficient erection. Urologists personally performing PDU were more likely to assess the cavernosal artery flow using recommended techniques with the probe at the proximal penile shaft (73% vs 40%) and at a 60-degree angle or less (68% vs 36%) compared with non-urologists (p < 0.01). Large differences in PDU diagnostic thresholds were apparent. Only 38% of respondents defined arterial insufficiency with a peak systolic velocity < 25 cm/s, while 53% of respondents defined venous occlusive disease with an end diastolic velocity > 5 cm/s. This is the first study to assess the variability in the PDU protocol and practice patterns, and to pinpoint areas of improvement. As in other surveys, recall bias, generalizability, and response rate (9.5%) are inherent limitations to this study. Although most respondents report utilizing a standardized PDU protocol, widespread variation exists among practitioners in terms of both technique and interpretation, limiting accurate diagnosis and appropriate treatment of penile conditions.

RESUMO

BACKGROUND: Antibiotic optimization is an urgent international issue. Regulatory frameworks, including the requirement to have a functioning antimicrobial stewardship (AMS) programme, are now ubiquitous across the hospital sector nationally and internationally. However, healthcare is ultimately delivered in a diverse range of institutional settings and social contexts. There is emerging evidence that implementation of antibiotic optimization strategies may be inappropriate or even counterproductive to attempts to optimize in atypical healthcare settings. AIM: To document the experiences and perspectives of clinical staff in a remote healthcare setting in Australia with respect to antimicrobial use, and strategies for optimization in that environment. METHODS: Semi-structured qualitative interviews were conducted with 30 healthcare professionals, including doctors, nurses and pharmacists, from a remote hospital in Queensland, Australia. FINDINGS: Four themes were identified from the analysis as key challenges to antibiotic optimization: (i) AMS as externally driven, and local knowledge sidelined; (ii) perceptions of heightened local population risks, treatment failure and the subsequent pressure to over-use of antimicrobials; (iii) interprofessional relationship dynamics including medical hierarchical structures perceived as a barrier to AMS; (iv) a clinical workforce dominated by transient locum staff and other process issues were perceived as significant barriers. CONCLUSION: The perceptions of healthcare professionals in this site lead to the conclusion that antimicrobial regulations and practice improvement strategies more generally are unlikely to succeed if they fail to accommodate and respect the context of care, the resource and structural constraints of the setting, and the specificities of particular populations (and subsequent clinical 'know-how').

RESUMO

INTRODUCTION: In this study we holistically describe and characterize the current state of urology practice by evaluating compensation, workload and practice factors as they relate to our demographic makeup as a specialty. METHODS: We collaborated with the American Urological Association to query its domestic membership of practicing urologists regarding socioeconomic, workforce and quality of life issues. The survey consisted of 26 questions and took approximately 13 minutes to complete. A total of 733 responders had complete data for the factors statistically analyzed in the study. RESULTS: Mean yearly compensation for urologists surveyed was $404,755 and median compensation was $380,000 (IQR $300,000-480,000). Female respondents had a significantly lower median yearly compensation vs males ($318,422 vs $400,000) on univariate and multivariate analysis. Respondents reported a median of 60 work hours per week (IQR 50-60) and the median number of call days per month was 7 (IQR 5-10). Of the respondents 62% indicated that they use advanced practice providers in their practice. In addition, 30% reported employed status, 49% reported self-employed status and 21% reported academic status. Overall 20% of respondents plan to retire within 5 years and 40% within 10 years. CONCLUSIONS: Higher income was associated with greater job satisfaction and hourly wage appeared to decrease at increased work hours per week. Several workplace and demographic factors drive compensation, number of hours worked per week, number of call days per month and job satisfaction.

RESUMO

Erectile dysfunction (ED) is a common problem in older men and occurs with even greater frequency following the treatment of pelvic malignancies. Inflatable penile prosthesis (IPP) implantation is a safe and effective form of definitive ED treatment for those men who fail more conservative measures, and it can be used with similar outcomes in men following cancer therapy. Although many of these men remain dissatisfied with other therapeutic options for ED, IPPs are underutilized in this population. This review will discuss the current practice patterns, outcomes and nuances to surgical technique regarding the use of IPPs in patients with ED following cancer therapy.

RESUMO

Vasectomy is the method of contraception chosen by more than 500,000 American men annually, and by upwards of 8% of married couples worldwide. However, following the procedure, nearly 20% of men express the desire for children in the future, and approximately 2-6% of American men will ultimately undergo vasectomy reversal (VR). VR is a complex microsurgical procedure. Intraoperative decision-making, surgical technique, and postoperative management are each critical step in achieving high success rates. The aim of this article is to provide a detailed description of the operative and perioperative procedures employed by surgeons performing VRs.

RESUMO

BACKGROUND: Suboptimal antibiotic use in respiratory infections is widespread in hospital medicine and primary care. Antimicrobial stewardship (AMS) teams within hospitals, commonly led by infectious diseases physicians, are frequently charged with optimizing the use of respiratory antibiotics, but there is limited information on what drives antibiotic use in this area of clinical medicine, or on how AMS is perceived. AIM: To explore the perceptions of hospital respiratory clinicians on AMS in respiratory medicine. METHODS: In-depth interviews were conducted with 28 clinicians (13 doctors and 15 nurses) from two hospitals in Australia. Data were analysed thematically using the framework approach. FINDINGS: Four key barriers to the integration of AMS processes within respiratory medicine, from the participants' perspectives, were identified: CONCLUSIONS: AMS processes are introduced in hospitals with established social structures and knowledge bases. This study found that AMS in respiratory medicine challenges and conflicts with many of these dynamics. If the influence of these dynamics is not considered, AMS processes may not be effective in containing antibiotic use in hospital respiratory medicine.

RESUMO

In addition to a high spatial resolution and well characterised dose response, one of the major advantages of radiochromic film as a dosimeter is that sheets of film can be cut into pieces suitable for use as calibration films, and for in vivo and phantom measurements. The cutting of film is typically done using scissors or a guillotine, and this process can be time-consuming, limited in precision, requires extensive handling and does not allow holes to be cut from the film without cutting from an existing edge. This study investigated the use of a Brother ScanNCut hobby cutting system for EBT3 film preparation. The optimal operating parameters (blade size, pressure, speed) that resulted in precise cuts with minimal delamination at cut edges were identified using test cutting patterns. These parameters were then used to cut a large film insert for a stereotactic head phantom for comparison against an insert cut with scissors. While the hobby cutting system caused a wider region of delamination at the film edge (1.8 mm) compared to scissors (1 mm), the hobby cutting system was found to be able to produce reproducible cuts more efficiently and more accurately than scissors. The use of the hobby cutting system is recommended for complex phantom inserts (containing sharp corners or holes for alignment rods) or in situations where large numbers of film pieces need to be prepared.

RESUMO

INTRODUCTION: Projections suggest a significant shortage of urologists coupled with an increasing burden of urological disease due to an aging population. To meet this need, urologists have increasingly partnered with advanced practice providers. However, to this point the advanced practice provider workforce has not been comprehensively evaluated. Understanding the impact of advanced practice providers on the urology workforce is essential to maximize collaborative care as we strive for value and quality in evolving delivery models. METHODS: A 29-item, web based survey was administered to advanced practice providers identified by the AUA (American Urological Association), UAPA (Urological Association of Physician Assistants) and SUNA (Society of Urologic Nurses and Associates), querying many aspects of their practice. RESULTS: A total of 296 advanced practice providers completed the survey. Advanced practice nurses comprised 62% of respondents while physician assistants comprised the remaining 38%. More than two-thirds of the respondents were female and median age was 46 years. Only 6% reported having participated in formal postgraduate urological training. Advanced practice providers were evenly divided between institutional and private practice settings, and overwhelmingly in urban or suburban environments. The majority of advanced practice providers practice in the ambulatory setting (74%) and characterize their practice as general urology (72%). Overall 81% reported performing procedures independently, with 63% performing some procedures considered to be of moderate or high complexity. CONCLUSIONS: Advanced practice providers are active in the provision of urological care in many roles, including complex procedures. Given future workforce needs, advanced practice providers will likely assume additional responsibilities. As roles shift we must ensure we have the necessary educational and training opportunities to equip this vital part of our workforce.

RESUMO

OBJECTIVES: This study aimed to examine how hospital doctors balance competing concerns around antibiotic use and resistance, with a focus on individual care versus broader public health considerations. METHODS: Sixty-four doctors across two hospitals in Australia participated in semi-structured interviews about their perspectives on antibiotic resistance and prescribing decisions. Results were analysed using the framework approach. RESULTS: The first theme focused on the significance of antimicrobial resistance (AMR) and the role of hospital doctors. Participants did not perceive resistance to be central to clinical decision-making, and externalised the resistance threat. They perceived themselves as separated from the issue of escalating resistance, viewing the key drivers to be overseas use, use in agriculture, and community prescribing. The second theme was around balancing risks. Immediate clinical risks were described as prioritised over long term population risk. Participants described concern around reputational and legal risks, which were perceived to be associated with under-prescribing of antibiotics. Over-prescribing was described by participants to be easier and without perceived immediate risk to them or to patients. CONCLUSION: Hospital doctors perceived antimicrobial resistance as externally produced and described clinical concerns taking precedence in individual antibiotic decisions. These dual processes mean that a population health model has limited traction in the hospital context. The externalisation of resistance leads to a sense of futility in changing practice, which combines with the pressures of acute medicine to prioritise immediate patient outcomes. Such dynamics are leading to antibiotic optimisation as a low or absent priority in hospital clinician antibiotic decision-making.

RESUMO

BACKGROUND: Antibiotic optimization in hospitals is an increasingly critical priority in the context of proliferating resistance. Despite the emphasis on doctors, optimizing antibiotic use within hospitals requires an understanding of how different stakeholders, including non-prescribers, influence practice and practice change. AIM: This study was designed to understand Australian hospital managers' perspectives on antimicrobial resistance, managing antibiotic governance, and negotiating clinical vis-à-vis managerial priorities. METHODS: Twenty-three managers in three hospitals participated in qualitative semi-structured interviews in Australia in 2014 and 2015. Data were systematically coded and thematically analysed. FINDINGS: The findings demonstrate, from a managerial perspective: (1) competing demands that can hinder the prioritization of antibiotic governance; (2) ineffectiveness of audit and monitoring methods that limit rationalization for change; (3) limited clinical education and feedback to doctors; and (4) management-directed change processes are constrained by the perceived absence of a 'culture of accountability' for antimicrobial use amongst doctors. CONCLUSION: Hospital managers report considerable structural and interprofessional challenges to actualizing antibiotic optimization and governance. These challenges place optimization as a lower priority vis-à-vis other issues that management are confronted with in hospital settings, and emphasize the importance of antimicrobial stewardship (AMS) programmes that engage management in understanding and addressing the barriers to change.

RESUMO

OBJECTIVE: To evaluate how varicocele repair (VR) impacts pregnancy (PRs) and live birth rates in infertile couples undergoing assisted reproduction wherein the male partner has oligospermia or azoospermia and a history of varicocele. DESIGN: Systematic review and meta-analysis. SETTING: Not applicable. PATIENT(S): Azoospermic and oligospermic males with varicoceles and in couples undergoing assisted reproductive technology (ART) with IUI, IVF, or testicular sperm extraction (TESE) with IVF and intracytoplasmic sperm injection (ICSI). INTERVENTION(S): Measurement of PRs, live birth, and sperm extraction rates. MAIN OUTCOME MEASURE(S): Odds ratios for the impact of VR on PRs, live birth, and sperm extraction rates for couples undergoing ART. RESULT(S): Seven articles involving a total of 1,241 patients were included. Meta-analysis showed that VR improved live birth rates for the oligospermic (odds ratio [OR] = 1.699) and combined oligospermic/azoospermic groups (OR = 1.761). Pregnancy rates were higher in the azoospermic group (OR = 2.336) and combined oligospermic/azoospermic groups (OR = 1.760). Live birth rates were higher for patients undergoing IUI after VR (OR = 8.360). Sperm retrieval rates were higher in persistently azoospermic men after VR (OR = 2.509). CONCLUSION(S): Oligospermic and azoospermic patients with clinical varicocele who undergo VR experience improved live birth rates and PRs with IVF or IVF/ICSI. For persistently azoospermic men after VR requiring TESE for IVF/ICSI, VR improves sperm retrieval rates. Therefore, VR should be considered to have substantial benefits for couples with a clinical varicocele even if oligospermia or azoospermia persists after repair and ART is required.

RESUMO

OBJECTIVE: To forecast the size and composition of the urologist and urology advanced care provider (ACP; nurse practitioner, physicians' assistant) workforce over the next 20 years. METHODS: Current urologist workforce was estimated from the American Board of Urology certification data and the 2014 American Urological Association (AUA) Census. Incoming workforce was estimated from the American Board of Urology and AUA residency match data. Estimates of the ACP workforce were extracted from the 2012 AUA Physician Survey. Full-time equivalent (FTE) calculations were based on a 2014 urology workforce survey. Workforce projections were created using a stock and flow population model with multiple alternative forecast scenarios. RESULTS: Slight growth in overall (urologist + ACP) workforce FTEs is expected, from 14,792 in 2015 to 15,160 in 2035. A significant decline in urologist FTEs is likely, from 11,221 in 2015 to 8859 in 2035. ACPs should increase markedly, from 8,710 in 2015 to 15,369 in 2035. Female urologists should increase by 2035, from the current 7.0% to 18.6% of urologist workforce. Alternate scenarios were evaluated, with forecasted FTEs in 2035 ranging from 14,066 to 17,675. In 2035, workforce shortage predictions range from 12% to 46%. CONCLUSION: With a decrease in urologists over the coming decades, urologists and ACPs may not meet future demand. This forecast highlights the need for discussion and planning among leadership in the field to find creative solutions for this impending workforce shortage.
