RESUMO

An outbreak of human immunodeficiency virus (HIV) among people who inject drugs in Glasgow, Scotland started in 2014. We describe 156 cases over 5 years and evaluate the impact of clinical interventions using virological and phylogenetic analysis. We established (1) HIV services within homeless health facilities, including outreach nurses, and (2) antiretroviral therapy (ART) via community pharmacies. Implementation of the new model reduced time to ART initiation from 264 to 23 days and increased community viral load suppression rates to 86%. Phylogenetic analysis demonstrated that 2019 diagnoses were concentrated within a single network. Traditional HIV care models require adaptation for this highly complex population.

RESUMO

Since the Journal of the Medical Library Association (JMLA) Virtual Projects section was first announced in 2012, the virtual projects featured in the JMLA have expanded or improved library spaces, services, collaborations, connections, and future directions. Virtual projects selected by the JMLA Virtual Projects Section Advisory Committee have been both practical and responsive to library and patron needs and illustrate ways that librarians are leading their communities and services in new directions. Virtual projects highlighted in this year's section demonstrate innovative adaptations of technology into the modern medical library that strengthen collaborative commitments and clinical and research partnerships. They also illustrate how technologies support the idea of "library as place" by providing spaces for users to explore new technologies, as well as tools for space and service planning. This year's virtual projects fully embrace changes in learning, research patterns, technologies, and the role of the health sciences librarian and the library.

RESUMO

Drug development involves a multi-stage process of drug discovery, animal studies and human clinical trials to assess the safety and efficacy of new medications. Rare disease drug development involves a much smaller number of affected patients, a predominance of pediatric patients and more complicated disease presentation. Post-approval studies are designed to address several limitations associated with the rare disease clinical trials.National and international regulatory agencies in the US and Europe have adopted similar approaches to requirements post-approval data for rare diseases and orphan drug indications. The US FDA published guidance in 2011 and the European Medicines Agency in 2015.Post-approval studies for rare diseases include observational studies, pragmatic trials and randomized controlled studies. Observational studies include both original data collection studies and the use of secondary data (retrospective studies). Original data collection can address limitations of retrospective studies resulting from incomplete information in secondary data sources. Disease registries focus on detail about a broad range of patients with a rare disease while product-related registries focus on specific health care outcomes associated with a single product and may incorporate a comparator of an alternative therapy or therapies.Rare disease patients can be difficult to find and enroll in a registry using conventional physician based driven recruitment. The study process also needs to recognize changes in the patient's disease and lifestyle and adapt both the study design and methods over time. Many rare diseases have strong patient advocacy groups that can in aid the design and execution of rare disease registries.

RESUMO

OBJECTIVE: The project identified a set of core competencies for librarians who are involved in systematic reviews. METHODS: A team of seven informationists with broad systematic review experience examined existing systematic review standards, conducted a literature search, and used their own expertise to identify core competencies and skills that are necessary to undertake various roles in systematic review projects. RESULTS: The team identified a total of six competencies for librarian involvement in systematic reviews: "Systematic review foundations," "Process management and communication," "Research methodology," "Comprehensive searching," "Data management," and "Reporting." Within each competency are the associated skills and knowledge pieces (indicators). Competence can be measured using an adaptation of Miller's Pyramid for Clinical Assessment, either through self-assessment or identification of formal assessment instruments. CONCLUSIONS: The Systematic Review Competencies Framework provides a standards-based, flexible way for librarians and organizations to identify areas of competence and areas in need of development to build capacity for systematic review integration. The framework can be used to identify or develop appropriate assessment tools and to target skill development opportunities.

RESUMO

Diabetic neuropathy is the most common microvascular complication of diabetes mellitus with high morbidity and mortality, and low quality of life. It has a broad spectrum of clinical forms, although distal symmetrical polyneuropathy is the most prevalent. Several oral complications including burning mouth syndrome, dry mouth, and impairment of the senses taste and smell are less-known manifestations of diabetic neuropathy and often overlooked. Periodontitis, tooth loss, and temporomandibular joint dysfunction may be also present in these patients and are equally debilitating. Periodontitis was declared the sixth complication of diabetes in 1993 and may contribute to poor glucose control. Hence, periodontitis and diabetes mutually and adversely affect each other. This review summarizes the available body of scientific literature that discusses oral manifestations in patients with diabetic neuropathy and identifies important areas where more research is needed.

RESUMO

Chimeric antigen receptor (CAR) T-cell therapy is a human gene therapy product where T cells from a patient are genetically modified to enable them to recognize desired target antigen(s) more effectively. In recent years, promising antitumor activity has been seen with autologous CAR T cells. Since 2017, six CAR T-cell therapies for the treatment of hematological malignancies have been approved by the Food and Drug Administration (FDA). Despite the rapid progress of CAR T-cell therapies, considerable statistical challenges still exist for this category of products across all phases of clinical development that need to be addressed. These include (but not limited to) dose finding strategy, implementation of the estimand framework, use of real-world data in contextualizing single-arm CAR T trials, analysis of safety data and long-term follow-up studies. This paper is the first step in summarizing and addressing these statistical hurdles based on the development of the six approved CAR T-cell products.

RESUMO

ADAMTS proteases typically employ some combination of ancillary C-terminal disintegrin-like, thrombospondin-1, cysteine-rich, and spacer domains to bind substrates and facilitate proteolysis by an N-terminal metalloprotease domain. We constructed chimeric proteases and substrates to examine the role of C-terminal domains of ADAMTS13 and ADAMTS5 in the recognition of their physiological cleavage sites in von Willebrand factor (VWF) and aggrecan, respectively. ADAMTS5 cleaves Glu(373)-Ala(374) and Glu(1480)-Gly(1481) bonds in bovine aggrecan but does not cleave VWF. Conversely, ADAMTS13 cleaves the Tyr(1605)-Met(1606) bond of VWF, which is exposed by fluid shear stress but cannot cleave aggrecan. Replacing the thrombospondin-1/cysteine-rich/spacer domains of ADAMTS5 with those of ADAMTS13 conferred the ability to cleave the Glu(1615)-Ile(1616) bond of VWF domain A2 in peptide substrates or VWF multimers that had been sheared; native (unsheared) VWF multimers were resistant. Thus, by recombining exosites, we engineered ADAMTS5 to cleave a new bond in VWF, preserving physiological regulation by fluid shear stress. The results demonstrate that noncatalytic thrombospondin-1/cysteine-rich/spacer domains are principal modifiers of substrate recognition and cleavage by both ADAMTS5 and ADAMTS13. Noncatalytic domains may perform similar functions in other ADAMTS family members.

RESUMO

Tappeh Sang-e Chakhmaq is the only Neolithic site in Northeastern Iran, characterised by aceramic and ceramic levels corresponding to an occupation of 1500 years from the eighth to the end of the sixth millennium BCE. The Western and Eastern Mounds represent the oldest and longest occupation among the sites identified East of the Zagros, providing a unique context to explore the origin and spread of farming outside the core area of the Eastern Fertile Crescent. We present data about the first harvesting activities in the Northeastern Iranian Central Plateau by applying usewear and microtexture analysis through confocal microscopy on sickle gloss blades. Our results indicate a community of pioneer farmers who settled down in the area carrying with them both domestic cereals as well as advanced techniques of cereal cultivation. We demonstrate that most of the tools were used for harvesting cereals in a fully ripened state collected near the ground, indicating a well-established cereal cultivation strategy. The use of straight shafts with parallel inserts in Tappeh Sang-e Chakhmaq, as known in some sites in the Zagros, suggests the dispersal of farming practices and technologies from the Eastern Fertile Crescent north-eastward across Iran. We observe an evolution in the degree of ripeness of harvested cereals along the first four levels of occupation of the Western Mound, where semi-ripe harvesting is relatively important, suggesting that domestic cereals to be harvested before full maturity were introduced into the village. From the topmost of the Western Mound and along the occupation of the Eastern Mound, ripe harvesting is dominant, showing a well-established cultivation strategy of fully mature cereal. This shift could indicate an in-situ evolution towards a better-established agricultural technology, including harvesting riper crops, that would have resulted in higher yields, as cereals were collected when the grain was fully formed.

RESUMO

Thrombotic thrombocytopenic purpura (TTP) is the prototypical microangiopathy characterized by disseminated microthromboses, hemolytic anemia, and ultimately organ dysfunction. A link with deficiency of the von Willebrand factor-cleaving protease (ADAMTS13) has been demonstrated, but additional genetic and/or environmental triggers are thought to be required to incite acute illness. Here we report that 4 days of ADAMTS13 functional inhibition is sufficient to induce TTP in the baboon (Papio ursinus), in the absence of inciting triggers because injections with an inhibitory monoclonal antibody (mAb) consistently (n = 6) induced severe thrombocytopenia (< 12 × 10(9)/L), microangiopathic hemolytic anemia, and a rapid rise in serum lactate dehydrogenase. Immunohistochemical staining revealed the characteristic disseminated platelet- and von Willebrand factor-rich thrombi in kidney, heart, brain, and spleen but not lungs. Prolonged inhibition (14 days, n = 1) caused myocardial ischemic damage and asplenia but not death. Control animals (n = 5) receiving equal doses of a noninhibitory anti-ADAMTS13 mAb remained unaffected. Our results provide evidence for a direct link between TTP and ADAMTS13 inhibition and for a mild disease onset. Furthermore, we present a reliable animal model of this disease as an opportunity for the development and validation of novel treatment strategies.

RESUMO

PURPOSE: Patients who have cancer have leveraged the Internet to gain a better understanding of their disease and connect across geographic boundaries with others facing the same challenges. Online cancer communities have developed into resources that highlight new research and evolving care pathways. Combined with increasing health literacy and social media, they have enabled some patients to become experts in their cancer. This combination of empowerment and expertise describes the new "e-patients." METHODS: We reviewed the literature to identify key areas where expert e-patients have directly participated in advancing cancer medicine, as well as opportunities available to those who wish to become more involved in research advocacy. RESULTS: E-patients are widely acknowledged as key stakeholders in oncology by clinicians, researchers, cancer centers, government agencies, and nonprofits. Their input is vital for informing cancer care delivery, developing and launching research initiatives, creating care guidelines and pathways, and formulating policy. CONCLUSION: Expert e-patients play an expanded role in their own care and in larger conversations regarding practice, research, and policy. Clinicians can engage e-patients as partners in cancer care as we work together towards improving health care access and outcomes for people with cancer.

RESUMO

Background: Opaganib, an oral sphingosine kinase-2 inhibitor with antiviral and anti-inflammatory properties, was shown to inhibit severe acute respiratory syndrome coronavirus 2 replication in vitro. We thus considered that opaganib could be beneficial for moderate to severe coronavirus disease 2019 (COVID-19) pneumonia. The objective of the study was to evaluate the safety of opaganib and its effect on supplemental oxygen requirements and time to hospital discharge in COVID-19 pneumonia hospitalized patients requiring supplemental oxygen. Methods: This Phase 2a, randomized, double-blind, placebo-controlled study was conducted between July and December 2020 in 8 sites in the United States. Forty-two enrolled patients received opaganib (n = 23) or placebo (n = 19) added to standard of care for up to 14 days and were followed up for 28 days after their last dose of opaganib/placebo. Results: There were no safety concerns arising in this study. The incidence of ≥Grade 3 treatment-emergent adverse events was 17.4% and 33.3% in the opaganib and placebo groups, respectively. Three deaths occurred in each group. A numerical advantage for opaganib over placebo was observed in in this nonpowered study reflected by total supplemental oxygen requirement from baseline to Day 14, the requirement for supplemental oxygen for at least 24 hours by Day 14, and hospital discharge. Conclusions: In this proof-of-concept study, hypoxic, hospitalized patients receiving oral opaganib had a similar safety profile to placebo-treated patients, with preliminary evidence of benefit for opaganib as measured by supplementary oxygen requirement and earlier hospital discharge. These findings support further evaluation of opaganib in this population.

RESUMO

BACKGROUND: Acute-on-chronic liver failure (ACLF) represents a rising global healthcare burden, characterised by increasing prevalence among patients with decompensated cirrhosis who have a 28-day transplantation-free mortality of 33.9%. Due to disease complexity and a high prevalence of socio-economic disadvantage, there are deficits in quality of care and adherence to guideline-based treatment in this cohort. Compared to other chronic conditions such as heart failure, those with liver disease have reduced access to integrated ambulatory care services. The LivR Well programme is a multidisciplinary intervention aimed at improving 28-day mortality and reducing 30-day readmission through a home-based, liver optimisation programme implemented in the first 28 days after an admission with either ACLF or hepatic decompensation. Outcomes from our feasibility study suggest that the intervention is safe and acceptable to patients and carers. METHODS: We will recruit adult patients with chronic liver disease from the emergency departments, in-patient admissions, and an ambulatory liver clinic of a multi-site quaternary health service in Melbourne, Australia. A total of 120 patients meeting EF-Clif criteria will be recruited to the ACLF arm, and 320 patients to the hepatic decompensation arm. Participants in each cohort will be randomised to the intervention arm, a 28-day multidisciplinary programme or to standard ambulatory care in a 1:1 ratio. The intervention arm includes access to nursing, pharmacy, physiotherapy, dietetics, social work, and neuropsychiatry clinicians. For the ACLF cohort, the primary outcome is 28-day mortality. For the hepatic decompensation cohort, the primary outcome is 30-day re-admission. Secondary outcomes assess changes in liver disease severity and quality of life. An interim analysis will be performed at 50% recruitment to consider early cessation of the trial if the intervention is superior to the control, as suggested in our feasibility study. A cost-effectiveness analysis will be performed. Patients will be followed up for 12 weeks from randomisation. Three exploratory subgroup analyses will be conducted by (a) source of referral, (b) unplanned hospitalisation, and (c) concurrent COVID-19. The trial has been registered with the Australian New Zealand Clinical Trials Registry. DISCUSSION: This study implements a multidisciplinary intervention for ACLF patients with proven benefits in other chronic diseases with the addition of novel digital health tools to enable remote patient monitoring during the COVID-19 pandemic. Our feasibility study demonstrates safety and acceptability and suggests clinical improvement in a small sample size. An RCT is required to generate robust outcomes in this frail, high healthcare resource utilisation cohort with high readmission and mortality risk. Interventions such as LivR Well are urgently required but also need to be evaluated to ensure feasibility, replicability, and scalability across different healthcare systems. The implications of this trial include the generalisability of the programme for implementation across regional and urban centres.

RESUMO

The gram-positive pathogen Streptococcus pyogenes injects a beta-NAD(+) glycohydrolase (SPN) into the cytosol of an infected host cell using the cytolysin-mediated translocation pathway. In this compartment, SPN accelerates the death of the host cell by an unknown mechanism that may involve its beta-NAD(+)-dependent enzyme activities. SPN has been reported to possess the unique characteristic of not only catalyzing hydrolysis of beta-NAD(+), but also carrying out ADP-ribosyl cyclase and ADP-ribosyltransferase activities, making SPN the only beta-NAD(+) glycohydrolase that can catalyze all of these reactions. With the long term goal of understanding how these activities may contribute to pathogenesis, we have further characterized the enzymatic activity of SPN using highly purified recombinant protein. Kinetic studies of the multiple activities of SPN revealed that SPN possessed only beta-NAD(+) hydrolytic activity and lacked detectable ADP-ribosyl cyclase and ADP-ribosyltransferase activities. Similarly, SPN was unable to catalyze cyclic ADPR hydrolysis, and could not catalyze methanolysis or transglycosidation. Kinetic analysis of product inhibition by recombinant SPN demonstrated an ordered uni-bi mechanism, with ADP-ribose being released as a second product. SPN was unaffected by product inhibition using nicotinamide, suggesting that this moiety contributes little to the binding energy of the substrate. Upon transformation, SPN was toxic to Saccharomyces cerevisiae, whereas a glycohydrolase-inactive SPN allowed for viability. Taken together, these data suggest that SPN functions exclusively as a strict beta-NAD(+) glycohydrolase during pathogenesis.

RESUMO

BACKGROUND: The number of surgical techniques for decompression and solid interbody fusion as treatment for cervical spondylosis has increased rapidly, but the rationale for the choice between different techniques remains unclear. OBJECTIVES: To determine which technique of anterior interbody fusion gives the best clinical and radiological outcomes in patients with single- or double-level degenerative disc disease of the cervical spine. SEARCH STRATEGY: We searched CENTRAL (The Cochrane Library 2009, issue 1), MEDLINE (1966 to May 2009), EMBASE (1980 to May 2009), BIOSIS (2004 to May 2009), and references of selected articles. SELECTION CRITERIA: Randomised comparative studies that compared anterior cervical decompression and interbody fusion techniques for participants with chronic degenerative disc disease. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed risk of bias using the Cochrane Back Review Group criteria. Data on demographics, intervention details and outcome measures were extracted onto a pre-tested data extraction form. MAIN RESULTS: Thirty-three small studies ( 2267 patients) compared different fusion techniques. The major treatments were discectomy alone, addition of an interbody fusion procedure (autograft, allograft, cement, or cage), and addition of anterior plates. Eight studies had a low risk of bias. Few studies reported on pain, therefore, at best, there was very low quality evidence of little or no difference in pain relief between the different techniques. We found moderate quality evidence for these secondary outcomes: no statistically significant difference in Odom's criteria between iliac crest autograft and a metal cage (6 studies, RR 1.11 (95% CI 0.99 to1.24)); bone graft produced more effective fusion than discectomy alone (5 studies, RR 0.22 (95% CI 0.17 to 0.48)); no statistically significant difference in complication rates between discectomy alone and iliac crest autograft (7 studies, RR 1.56 (95% CI 0.71 to 3.43)); and low quality evidence that iliac crest autograft results in better fusion than a cage (5 studies, RR 1.87 (95% CI 1.10 to 3.17)); but more complications (7 studies, RR 0.33 (95% CI 0.12 to 0.92)). AUTHORS' CONCLUSIONS: When the working mechanism for pain relief and functional improvement is fusion of the motion segment, there is low quality evidence that iliac crest autograft appears to be the better technique. When ignoring fusion rates and looking at complication rates, a cage has a weak evidence base over iliac crest autograft, but not over discectomy alone. Future research should compare additional instrumentation such as screws, plates, and cages against discectomy with or without autograft.

RESUMO

BACKGROUND: Postoperative pain and anxiety are common in cardiac surgery patients. Studies have suggested that music can decrease anxiety in hospitalized patients. Primary Study Objective This study focused on the efficacy and feasibility of special music, which included nature sounds, for pain and anxiety. METHODS/DESIGN: In this randomized controlled trial, postoperative cardiovascular surgery patients were randomly assigned to a music group to receive 20 minutes of standard postoperative care and music twice daily on postoperative days 2 through 4 or to a control group to receive 20 minutes of standard care with a quiet resting period twice daily on postoperative days 2 through 4. SETTING: Cardiovascular surgical unit of Saint Marys Hospital, Rochester, Minnesota. PARTICIPANTS: One hundred patients completed the study (music group, n = 49; control group, n = 51). Intervention The music was delivered through CD players in the patients' rooms. PRIMARY OUTCOME MEASURES: Pain, anxiety, satisfaction, and relaxation were evaluated from visual analog scales. RESULTS: Data showed a significant decrease in mean (SD) pain scores after the second session of day 2 for the music group (change, ?1.4 [1.4]) compared with the control group (change, ?0.4 [1.4]) (P = .001). Mean relaxation scores improved more at the first session of day 2 for the music group (change, 1.9 [2.7]) compared with the control group (change, 0.3 [2.9]) (P = .03). The music group also showed lower anxiety and increased satisfaction overall, but these differences were not statistically significant. No major barriers to using the therapy were identified. CONCLUSION: Recorded music and nature sounds can be integrated into the postoperative care of cardiovascular surgery patients. The recordings may provide an additional means for addressing common symptoms of pain and anxiety while providing a means of relaxation for these patients.

RESUMO

BACKGROUND AND PURPOSE: In the present study a classification system for the rheumatoid forefoot is reported with its intra- and interobserver reliability and clinical relevance. The classification is based on the sequence of anatomical changes resulting from the loss of integrity of the MTP joints, loss of motion and changes regarding the quality and position of the plantar soft tissues. It is hypothesized that with progression of the amount of deformity of the MTP joint(s), patients have more pain and functional loss. PATIENTS AND METHODS: In total 94 patients were included in the study following precise inclusion criteria. The forefeet of the patients were classified according to the introduced classification system by two observers in order to determine the intra- and interobserver reliability. The relation of the suggested classification between pain, function scores, and plantar foot pressure measurements was examined. RESULTS AND CONCLUSION: According to the Cohen's kappa and the ICC, the intra- and inter-observer reliability were high. Despite the large variation between subjects in a certain grade, a clear trend was found between increase in classification and VAS for pain, FFI difficulty with activities, and plantar peak pressure under the metatarsals. The suggested classification is of clinical relevance and can be used to develop therapeutical algorithms and to test interventions.

RESUMO

Cold ischemia and hence travel time can adversely affect outcomes of islet isolation. The aim of this study was to compare the isolation and transplant outcomes of donor pancreata according to the distance from islet isolation facility. Principally, those within a 50 km radius of the centre were compared with those from regional areas within the state and those from interstate donors within Australia. Organ donors were categorised according to distance from National Pancreas Transplant Unit Westmead (NPTU). Donor characteristics were analysed statistically against islet isolation outcomes. These were age, BMI, cause and mechanism of death, days in ICU, gender, inotrope and steroid use, cold ischemia time (CIT) and retrieval surgical team. Between March 2007 and December 2020, 297 islet isolations were performed at our centre. A total of 149 donor pancreata were local area, and 148 non-local regions. Mean distance from the isolation facility was 780.05 km. Mean pancreas CIT was 401.07 ± 137.71 min and was significantly different between local and non-local groups (297.2 vs. 487.5 min, p < 0.01). Mean age of donors was 45.22 years, mean BMI was 28.82, sex ratio was 48:52 F:M and mean time in ICU was 3.07 days. There was no significant difference between local and non-local for these characteristics. The mean CIT resulting in islet transplantation was 297.1 ± 91.5 min and longest CIT resulting in transplantation was 676 min. There was no significant difference in islet isolation outcomes between local and non-local donors for characteristics other than CIT. There was also no significant effect of distance from the isolation facility on positive islet transplant outcomes (C-peptide > 0.2 at 1 month post-transplant). Conclusions: Distance from the isolation centre did not impact on isolation or transplant outcomes supporting the ongoing nationwide use of shipping pancreata for islet isolation and transplantation.

RESUMO

BACKGROUND AND AIM: Patients with refractory ascites have frequent hospital admissions, which pose exposure risks in the context of the COVID-19 pandemic. The aim of this study was to investigate the safety and efficacy of a novel 12-week, multidisciplinary ambulatory care program allowing frequent low-volume ascitic drainage through a tunneled, intraperitoneal catheter (IPC). METHODS: Adult patients with cirrhosis complicated by refractory ascites were recruited through a liver clinic in a tertiary health service in Melbourne, Australia from April to December 2020. All patients were enrolled in a 12-week multidisciplinary program including medical, nursing, dietetics, and pharmacy support. A Rocket Medical IPC was inserted on day 1 with 1-2 L of ascitic fluid drained over 1-3 sessions per week either at the patients' homes or at the hospital day ward. Patients' demographics, death, complications, and self-reported outcomes were recorded. RESULTS: Twelve patients were enrolled with a median of 65-day (interquartile range [IQR]: 16.5-93) IPC duration between April and December 2020 across two periods of COVID-related lockdown in Melbourne, Australia. There were no IPC-related deaths. Early removal was necessitated in three patients due to leakage, nonadherence, and bacteremia. On day 30, the median self-reported health score increased from 50 (IQR: 50-70) to 78 (IQR: 50-85), attributable to a reduction in symptom burden. CONCLUSION: A multidisciplinary IPC program including the use of short-term IPC was safe and associated with a self-reported improvement in perceptions of health. In the context of the COVID-19 pandemic, the program aimed to reduce patient and clinician exposure, which is maintaining engagement and management of decompensated cirrhosis.
