RESUMEN

BACKGROUND: Female participants are underrepresented in randomised control trials conducted in urgent care settings. Although sex and gender are frequently reported within demographic data, it is less common for primary outcomes to be disaggregated by sex or gender. The aim of this review is to report sex and gender of participants in the primary papers published on research listed on the National Institute of Health and Care Research (NIHR) Trauma and Emergency Care (TEC) portfolio and how these data are presented. METHODS: This is a systematic review of the published outputs of interventional trials conducted in UK EDs. Interventional trials were eligible to be included in the review if they were registered on the NIHR TEC research portfolio from January 2010, if the primary paper was published before 31 December 2023 and if the research was delivered primarily in the ED. Trials were identified through the NIHR open data platform and the primary papers were identified through specific searches using MedLine, EMBASE and PubMed. The primary objective of the review is to quantify the proportion of sex-disaggregated or gender-disaggregated primary outcomes in clinical trials within UK emergency medicine. RESULTS: The initial search revealed 169 registered research projects on the NIHR TEC portfolio during the study period, of which 24 met the inclusion criteria. Overall, 76 719 participants were included, of which 31 374 (40%) were female. Only one trial (CRYOSTAT-2) reported a sex-disaggregated analysis of the effect of the intervention on either primary or secondary outcomes, and no sex-based difference in treatment effect was detected. CONCLUSIONS: Fewer females than males were included in TEC trials from 2010 to 2023. One trial reported the primary outcome stratified by sex. There is significant scope to increase the scientific value of TEC trials to females by funders.

RESUMEN

BACKGROUND: Supporting people to quit smoking is one of the most powerful interventions to improve health. The Emergency Department (ED) represents a potentially valuable opportunity to deliver a smoking cessation intervention if it is sufficiently resourced. The objective of this trial was to determine whether an opportunistic ED-based smoking cessation intervention can help people to quit smoking. METHODS: In this multicentre, parallel-group, randomised controlled superiority trial conducted between January and August 2022, adults who smoked daily and attended one of six UK EDs were randomised to intervention (brief advice, e-cigarette starter kit and referral to stop smoking services) or control (written information on stop smoking services). The primary outcome was biochemically validated abstinence at 6 months. RESULTS: An intention-to-treat analysis included 972 of 1443 people screened for inclusion (484 in the intervention group, 488 in the control group). Of 975 participants randomised, 3 were subsequently excluded, 17 withdrew and 287 were lost to follow-up. The 6-month biochemically-verified abstinence rate was 7.2% in the intervention group and 4.1% in the control group (relative risk 1.76; 95% CI 1.03 to 3.01; p=0.038). Self-reported 7-day abstinence at 6 months was 23.3% in the intervention group and 12.9% in the control group (relative risk 1.80; 95% CI 1.36 to 2.38; p<0.001). No serious adverse events related to taking part in the trial were reported. CONCLUSIONS: An opportunistic smoking cessation intervention comprising brief advice, an e-cigarette starter kit and referral to stop smoking services is effective for sustained smoking abstinence with few reported adverse events. TRIAL REGISTRATION NUMBER: NCT04854616.

RESUMEN

Mild traumatic brain injury is a common presentation to the emergency department, with current management often focusing on determining whether a patient requires a CT head scan and/or neurosurgical intervention. There is a growing appreciation that approximately 20%-40% of patients, including those with a negative (normal) CT, will develop ongoing symptoms for months to years, often termed post-concussion syndrome. Owing to the requirement for improved diagnostic and prognostic mechanisms, there has been increasing evidence concerning the utility of both imaging and blood biomarkers.Blood biomarkers offer the potential to better risk stratify patients for requirement of neuroimaging than current clinical decisions rules. However, improved assessment of the clinical utility is required prior to wide adoption. MRI, using clinical sequences and advanced quantitative methods, can detect lesions not visible on CT in up to 30% of patients that may explain, at least in part, some of the ongoing problems. The ability of an acute biomarker (be it imaging, blood or other) to highlight those patients at greater risk of ongoing deficits would allow for greater personalisation of follow-up care and resource allocation.We discuss here both the current evidence and the future potential clinical usage of blood biomarkers and advanced MRI to improve diagnostic pathways and outcome prediction following mild traumatic brain injury.

RESUMEN

This study aimed to identify factors that inde- pendently predict increased rates of transfusion following total hip arthroplasty (THA) surgery. A retrospective analysis of all patients undergoing THA surgery over 12 months was performed. Electronic operative records were analysed to determine the following patient factors: American Society of Anesthesiologists (ASA) grade, body mass index (BMI), co-morbidities, indication for surgery, surgical technique, type of implant used, haematological markers, hospital length of stay (LOS) and complications. A total of 244 patients were included. There were 141 females (58%) and 103 males (42%). The median age was 65±12. The median pre-operative blood volume was 4500mls (IQR; 4000-5200). The median blood loss was 1069mls (IQR; 775-1390). The total number of patients requiring transfusion was 28 (11%), with a median of two units being transfused. Pre-operative haemoglobin (p<0.001) level, haematocrit (p<0.001) level and weight (p=0.016) were found to be predictive of transfusion requirement as well as ASA grade (p=0.005). Application of an intra-operative surgical drain was associated with higher rates of transfusion (p<0.001). Our study strengthens the evidence that pre-operative haemoglobin and haematocrit levels are valuable predictors of patients requiring transfusion. Additionally, ASA grade may be viewed as a helpful factor in predicting risk of transfusion. A strategy incorporating pre-operative optimisation of modifiable factors may reduce rates of transfusion requirement.

RESUMEN

Associations between cleaning chemical exposures and asthma have previously been identified in professional cleaners and healthcare workers. Domestic workers, including housecleaners and caregivers, may receive similar exposures but in residential environments with lower ventilation rates. Study objectives were to compare exposures to occupational exposure limits (OELs), to determine relative contributions from individual cleaning tasks to overall exposure, and to evaluate the effects of ventilation and posture on exposure. Airborne chemical concentrations of sprayed cleaning chemicals (acetic acid or ammonia) were measured during typical cleaning tasks in a simulated residential work environment. Whole-house cleaning exposures (18 cleaning tasks) were measured using integrated personal sampling methods. Individual task exposures were measured with a sampling line attached to subjects' breathing zones, with readings recorded by a ppbRAE monitor, equipped with a photoionization detector calibrated for ammonia and acetic acid measurements. Integrated sampling results indicated no exposures above OELs occurred, but 95th percentile air concentrations would require risk management decisions. Exposure reductions were observed with increased source distance, with lower exposures from mopping floors compared to kneeling. Exposure reductions were also observed for most but not all tasks when ventilation was used, with implications that alternative exposure reduction methods may be needed.

RESUMEN

BACKGROUND: The large volume of patients, rapid staff turnover and high work pressure mean that the usability of all systems within the ED is important. The transition to electronic health records (EHRs) has brought many benefits to emergency care but imposes a significant burden on staff to enter data. Poor usability has a direct consequence and opportunity cost in staff time and resources that could otherwise be employed in patient care. This research measures the usability of EHR systems in UK EDs using a validated assessment tool. METHODS: This was a survey completed by members and fellows of the Royal College of Emergency Medicine conducted during summer 2019. The primary outcome was the System Usability Scale Score, which ranges from 0 (worst) to 100 (best). Scores were compared with an internationally recognised measure of acceptable usability of 68. Results were analysed by EHR system, country, healthcare organisation and physician grade. Only EHR systems with at least 20 responses were analysed. RESULTS: There were 1663 responses from a total population of 8794 (19%) representing 192 healthcare organisations (mainly UK NHS), and 25 EHR systems. Fifteen EHR systems had at least 20 responses and were included in the analysis. No EHR system achieved a median usability score that met the industry standard of acceptable usability.The median usability score was 53 (IQR 35-68). Individual EHR systems' scores ranged from 35 (IQR 26-53) to 65 (IQR 44-80). CONCLUSION: In this survey, no UK ED EHR system met the internationally validated standard of acceptable usability for information technology.

RESUMEN

The House Ball Community consists of sexual, gender and ethnic minority youth who form family-like houses and compete in balls. Many rely on community-based organisations as venues for socialising and accessing health-related resources. In recent years, urban gentrification has challenged the economic survival of the organisations that serve this community and its members. Between 2016 and 2017, we conducted 45 in-depth interviews with houses and gay families in the San Francisco Bay Area and regular participant observation at community events, including balls. In addition to forcing community organisations to close or move, rising rents have increased housing instability among Ballroom Community members, with some moving to distal locations. Participants felt nostalgia for organisations that provided HIV-related services and hosted balls in previous years, feeling the loss of space keenly. To maintain community and generate employment, the San Francisco Ballroom Community now offers Vogue classes at private dance studios. This allows participants to recruit new house members, welcoming a broader array of individuals into the community than those who have historically participated. However, accessing culturally appropriate sexual health services remains difficult. Health advocates should recognise that community organisations are necessary for diverse youth to build community and access sexual health services.

RESUMEN

African American men who have sex with men and women (MSMW) are among the populations with the highest need for HIV prevention programs in the USA. We tested a theory-based, community participatory behavioral intervention aiming to reduce sexual risk for HIV transmission in this population. A randomized clinical trial involving 396 African American MSMW who were assigned to a 4-session intervention involving HIV testing and counseling (n = 199) or to a HIV testing and counseling only (n = 197) control. In the 4-session intervention program, counselors provided education on HIV and STI risk, condom use, HIV testing, interpersonal sexual dynamics with both male and female partners, and motivational "triggers" of condomless sex. Participants completed baseline, 6-month, and 9-month assessments, and changes in HIV behavioral risk indicators were examined by condition and time. There were no statistically significant differences in sexual risk between the intervention condition and the control condition. Regardless of condition, participants reported significant reductions in mean number of condomless sex events with female casual partners from baseline (6.04) to 6 months (2.58) and 9 months (1.47), and with male casual partners from baseline (2.61) to 6 months (1.18) and 9 months (0.60). Condition-by-time interaction effects and condition main effects were non-significant. Although there were no significant differences by condition, findings support the effects of brief behavioral counseling and HIV testing on reducing condomless sex with casual female and male partners among African American MSMW. Future research should examine further the potential for brief behavioral counseling to promote biomedical HIV prevention and to reduce co-morbid health issues such as substance use among African American MSMW.

RESUMEN

Glaucoma is a multifactorial neurodegenerative disease associated with retinal ganglion cells (RGC) loss. Increasing reports of similarities in glaucoma and other neurodegenerative conditions have led to speculation that therapies for brain neurodegenerative disorders may also have potential as glaucoma therapies. Memantine is an N-methyl-d-aspartate (NMDA) antagonist approved for Alzheimer's disease treatment. Glutamate-induced excitotoxicity is implicated in glaucoma and NMDA receptor antagonism is advocated as a potential strategy for RGC preservation. This study describes the development of a topical formulation of memantine-loaded PLGA-PEG nanoparticles (MEM-NP) and investigates the efficacy of this formulation using a well-established glaucoma model. MEM-NPs <200 nm in diameter and incorporating 4 mg mL-1 of memantine were prepared with 0.35 mg mL-1 localized to the aqueous interior. In vitro assessment indicated sustained release from MEM-NPs and ex vivo ocular permeation studies demonstrated enhanced delivery. MEM-NPs were additionally found to be well tolerated in vitro (human retinoblastoma cells) and in vivo (Draize test). Finally, when applied topically in a rodent model of ocular hypertension for three weeks, MEM-NP eye drops were found to significantly (p < 0.0001) reduce RGC loss. These results suggest that topical MEM-NP is safe, well tolerated, and, most promisingly, neuroprotective in an experimental glaucoma model.

RESUMEN

Glaucoma is one of the leading causes of irreversible visual loss, which has been estimated to affect 3.5% of those over 40 years old and projected to affect a total of 112 million people by 2040. Such a dramatic increase in affected patients demonstrates the need for continual improvement in the way we diagnose and treat this condition. Annexin A5 is a 36 kDa protein that is ubiquitously expressed in humans and is studied as an indicator of apoptosis in several fields. This molecule has a high calcium-dependent affinity for phosphatidylserine, a cell membrane phospholipid externalized to the outer cell membrane in early apoptosis. The DARC (Detection of Apoptosing Retinal Cells) project uses fluorescently-labelled annexin A5 to assess glaucomatous degeneration, the inherent process of which is the apoptosis of retinal ganglion cells. Furthermore, this project has conducted investigation of the retinal apoptosis in the neurodegenerative conditions of the eye and brain. In this present study, we summarized the use of annexin A5 as a marker of apoptosis in the eye. We also relayed the progress of the DARC project, developing real-time imaging of retinal ganglion cell apoptosis in vivo from the experimental models of disease and identifying mechanisms underlying neurodegeneration and its treatments, which has been applied to the first human clinical trials. DARC has potential as a biomarker in neurodegeneration, especially in the research of novel treatments, and could be a useful tool for the diagnosis and monitoring of glaucoma.

RESUMEN

There is great individual variation in response to general anesthetics (GAs) leading to difficulties in optimal dosing and sometimes even accidental awareness during general anesthesia (AAGA). AAGA is a rare, but potentially devastating, complication affecting between 0.1% and 2% of patients undergoing surgery. The development of novel personalized screening techniques to accurately predict a patient's response to GAs and the risk of AAGA remains an unmet clinical need. In the present study, we demonstrate the principle of using a fluorescent reporter of the membrane dipole potential, di-8-ANEPPs, as a novel method to monitor anesthetic activity using a well-described inducer/noninducer pair. The membrane dipole potential has previously been suggested to contribute a novel mechanism of anesthetic action. We show that the fluorescence ratio of di-8-ANEPPs changed in response to physiological concentrations of the anesthetic, 1-chloro-1,2,2-trifluorocyclobutane (F3), but not the structurally similar noninducer, 1,2-dichlorohexafluorocyclobutane (F6), to artificial membranes and in vitro retinal cell systems. Modulation of the membrane dipole provides an explanation to overcome the limitations associated with the alternative membrane-mediated mechanisms of GA action. Furthermore, by combining this technique with noninvasive retinal imaging technologies, we propose that this technique could provide a novel and noninvasive technique to monitor GA susceptibility and identify patients at risk of AAGA.

RESUMEN

The assumption that intestinal metaplasia is a prerequisite for intraepithelial neoplasia/dysplasia and adenocarcinoma in the distal esophagus has been challenged by observations of adenocarcinoma without associated intestinal metaplasia. This study describes our experience of intestinal metaplasia in association with early Barrett neoplasia in distal esophagus and gastroesophageal junction. We reviewed the first endoscopic mucosal resection of 139 patients with biopsy-proven neoplasia. In index endoscopic mucosal resection, 110/139 (79%) cases showed intestinal metaplasia. Seven had intestinal metaplasia on prior biopsy specimens and three had intestinal metaplasia in subsequent specimens, totaling 120/139 (86%) patients showing intestinal metaplasia at some point supporting the theory of sampling error for absence of intestinal metaplasia in some cases. Those without intestinal metaplasia (13%) were enriched for higher stage disease (T1a Stolte m2 or above) supporting the assertion of obliteration of intestinal metaplasia by the advancing carcinoma. All cases of intraepithelial neoplasia and T1a Stolte m1 carcinomas had intestinal metaplasia (42/42). The average density of columnar-lined mucosa showing goblet cells was significantly less in shorter segments compared to those ≥3 cm (0.31 vs 0.51, P=0.0304). Cases where segments measured less than 1 cm were seen in a higher proportion of females and also tended to lack intestinal metaplasia. We conclude that early Barrett neoplasia is always associated with intestinal metaplasia; absence of intestinal metaplasia is attributable to sampling error or obliteration of residual intestinal metaplasia by neoplasia and those with segments less than 1 cm show atypical features for Barrett-related disease (absent intestinal metaplasia and female gender), supporting that gastroesophageal junction adenocarcinomas are heterogeneous.

RESUMEN

BACKGROUND: There is little research regarding the ability of Black men who have sex with men and women (BMSMW) to access and maintain HIV-related health care and treatment adherence. This population, who often insist on secrecy about their same-sex desire, may experience unique barriers to seeking regular care and treatment. METHODS: From March 2011-April 2014, we recruited 396 BMSMW in the San Francisco Bay Area to be enrolled in our randomized controlled trial. At baseline we administered a behavioral survey assessing: demographics, homelessness, employment, history of incarceration, HIV status and disclosure practices, care and treatment adherence. 64 men reported living with HIV at intake. To learn more about their experiences, we recruited N = 25 to participate in qualitative interviews, which were conducted April-December 2014. Topics included: current living situation, diagnosis story, disclosure practices, experiences of accessing and maintaining care and treatment, and HIV-related stigma. Recordings were transcribed and coded for major themes. RESULTS: Despite being located in an area where treatment is plentiful, men faced social and economic barriers to maintaining regular care and treatment adherence. Several findings emerged to shed light on this quandary: (1) Competing needs particularly around attaining stable housing, food security, and money created barriers to treatment and care; (2) Side effects of HIV medications discouraged men from adhering to treatment; (3) Provider and Institutional level characteristics influenced care engagement; (4) Disclosure and social support made a difference in care and treatment behaviors; and (5) Participants expressed a desire for group-based intervention activities to support treatment and care among HIV+ BMSMW. Inadequate engagement in the continuum of care for HIV was born out in the quantitative data where 28% of participants did not know their Viral Load. CONCLUSIONS: A holistic approach to HIV health for BMSMW would appear to translate to better outcomes for men living with HIV, where a goal of viral suppression must also include attending to their basic social and economic support needs.

RESUMEN

Over 60 million people worldwide are diagnosed with glaucomatous optic neuropathy, which is estimated to be responsible for 8.4 million cases of irreversible blindness globally. Glaucoma is associated with characteristic damage to the optic nerve and patterns of visual field loss which principally involves the loss of retinal ganglion cells (RGCs). At present, intraocular pressure (IOP) presents the only modifiable risk factor for glaucoma, although RGC and vision loss can continue in patients despite well-controlled IOP. This, coupled with the present inability to diagnose glaucoma until relatively late in the disease process, has led to intense investigations towards the development of novel techniques for the early diagnosis of disease. This review outlines our current understanding of the potential mechanisms underlying RGC and axonal loss in glaucoma. Similarities between glaucoma and other neurodegenerative diseases of the central nervous system are drawn before an overview of recent developments in techniques for monitoring RGC health is provided, including recent progress towards the development of RGC specific contrast agents. The review concludes by discussing techniques to assess glaucomatous changes in the brain using MRI and the clinical relevance of glaucomatous-associated changes in the visual centres of the brain.

RESUMEN

Malignancies of upper gastrointestinal tract are aggressive, and most locally advanced unresectable and metastatic cancers are managed by a combination of surgery and neoadjuvant/adjuvant chemotherapy and radiotherapy. Current therapeutic recommendations include targeted therapies based on biomarker expression of an individual tumor. All G/gastro-esophageal junction (GEJ) cancers should be tested for HER2 status as a reflex test at the time of diagnosis. Currently, testing for PDL 1 and mismatch repair protein status is optional. HER2 testing is restricted to adenocarcinomas only and endoscopic biopsies, resections, or cellblocks. Facilities should be available for performing validated immunohistochemical stains and in-situ hybridization techniques, and importantly, pathologists should be experienced with preanalytical and analytical issues and scoring criteria. Genomic profiling via next-generation sequencing (NGS) is another strategy that assess numerous mutations and other molecular events simultaneously, including HER2 amplification, MSS status, tumor mutation burden, and neurotrophic tropomyosin-receptor kinases gene fusions.

RESUMEN

BACKGROUND: Indonesia has lost more mangroves than any other country. The importance of mangroves for carbon storage and biodiversity is well recognised, but much less is known about what they contribute to the communities living near them who are called on to protect them. Malnutrition in Indonesia is high, with more than a third of children stunted, partly due to poor diets. Fish are nutrient-rich and are the most widely consumed animal source food in Indonesia, making the relationship between mangroves and fish consumption of great importance. Aquaculture is also tremendously important for fish production in Indonesia and has replaced large areas of mangroves over the last two decades. METHODS: We performed a cross-sectional, spatial analysis in this study. We combined data on fish consumption for rural Indonesian coastal households from the Indonesian National Socioeconomic Survey with spatial data on mangrove forest and aquaculture area from the Indonesian Ministry of Environment and Forestry to create a cross-sectional spatial dataset. Using a mixed-effects regression model, we estimated to what extent living in proximity to different densities of mangroves and aquaculture was associated with fresh fish consumption for rural coastal households. FINDINGS: Our sample included 6741 villages with 107 486 households in 2008. The results showed that rural coastal households residing near high-density mangroves consumed 28% (134/477) more fresh fish and other aquatic animals, and those residing near medium-density mangroves consumed 19% (90/477) more fresh fish and other aquatic animals, than coastal households who did not live near mangroves. Coastal households that lived near high-density aquaculture consumed 2% (9/536) more fresh fish, and those that lived near medium-density aquaculture consumed 1% (3/536) less, than other rural coastal households. INTERPRETATION: Mangroves contribute substantially to the food security and nutrition of coastal communities in Indonesia. This finding means that the conservation of mangroves is important not only for carbon storage and biodiversity, but also for the communities living near them. Aquaculture does not appear to offer similar food security benefits. FUNDING: Bureau for Economic Growth, Education, and Environment, United States Agency for International Development.

RESUMEN

The Indian rock pythons (Python molurus) are classified as a near-threatened snake species by the International Union for the Conservation of Nature and Natural Resources (IUCN); they are native to the Indian subcontinent and have experienced population declines caused primarily by poaching and habitat loss. We hand-captured the 14 rock pythons from villages, agricultural lands, and core forests to examine the species' home ranges. We later released/translocated them in different kilometer ranges at the Tiger Reserves. From December 2018 to December 2020, we obtained 401 radio-telemetry locations, with an average tracking duration of (444 ± 212 days), and a mean of 29 ± SD 16 data points per individual. We quantified home ranges and measured morphometric and ecological factors (sex, body size, and location) associated with intraspecific differences in home range size. We analyzed the home ranges of rock pythons using Auto correlated Kernel Density Estimates (AKDE). AKDEs can account for the auto-correlated nature of animal movement data and mitigate against biases stemming from inconsistent tracking time lags. Home range size varied from 1.4 ha to 8.1 km2 and averaged 4.2 km2. Differences in home range sizes could not be connected to body mass. Initial indications suggest that rock python home ranges are larger than other pythons.

RESUMEN

Part I of this paper considers the historical foundations, motivations, and evolution of veterans' disability and employment legislation in the United States. Utilizing disability and employment as its framework, Part II then defines, describes, and critiques contemporary policies for disabled veterans in the areas of federal employment protections and uses of Alternative Dispute Resolution (ADR) within the VA's disability decision review process. Part III discusses the roles played by disabled veterans and the federal government in policy reform, finding that both sides act as catalysts and barriers to legislative change. This paper concludes in Part IV, recommending legislation that integrates elements of disability care--currently under the auspices of the VA--into Medicare. Through this newly created insurance component, which this paper will call "Medicare Part V," disabled veterans will be eligible to access all hospitals and clinics currently accepting Medicare. This is anticipated to increase access to care in local facilities. Second, it is essential that the federal government devotes sufficient resources to conduct more longitudinal data collection studies, enabling a more comprehensive assessment of the transitional and employment resource needs of disabled veterans over time. Achieving a greater understanding of these needs may induce greater veteran participation rates in the labor force, benefiting employers and veterans alike. Finally, this paper calls for modernizing and optimizing the VA's claim appeals process by creating a secure online method of Alternative Dispute Resolution for appeals, specifically in Higher-Level Reviews (HLR's) of disability and compensation requests.
