RESUMEN

BACKGROUND: Maternal mortality rates continue to rise in the United States. Considerable racial disparities exist, as Black women face two to three times the risks of dying from pregnancy-related complications compared with white women. Doulas have been associated with improved maternal outcomes. This study aimed to 1) investigate Florida doulas' perspectives and influence on severe maternal morbidity/mortality and related inequities, as well as 2) identify opportunities for actionable change. The social ecological model, which acknowledges how individual, interpersonal, institutional, community, and public policy factors intersect, informed our analysis. METHODS: This qualitative study included seven online in-depth interviews and seven focus groups with doulas (N = 31) in Florida. Interview guides investigated how doulas perceive their role in the context of a) maternal morbidity and b) health disparities. RESULTS: Doulas associated maternal morbidity and health disparities with Black pregnant people, identifying racism as a major contributor. Doulas identified their role as one that most often intersects with the individual and interpersonal levels of the social ecological model. Doulas report providing positive social surveillance and emotional support, contributing education and resources, and championing for advocacy in health care settings. Actionable steps recommended by doulas to further mitigate health disparities include the integration of implicit bias training into doula certification programs, increasing public health funding to bolster a doula workforce that can serve racial and ethnic communities, establishing doula-hospital partnerships to improve relational communication, providing tailored resources for clients featuring representative messaging, and doulas' continued engagement in positive social surveillance of their clients. CONCLUSIONS: Doulas perceived their role as integral to mitigating maternal morbidity and health disparities, particularly in the context of supporting and advocating for birthing persons on all levels of the social ecological model. Equitable access to doulas for low-income and/or minoritized populations may be one key strategy to improve maternal health equity.

RESUMEN

OBJECTIVE: To determine how many times Ipas manual vacuum aspiration (MVA) instruments are reused, for what reasons, when the instruments are replaced and/or discarded, and what the barriers are to replacing them. METHODS: We conducted a mixed-methods cross-sectional study of health care providers who provide MVA services and key stakeholders in the supply chain to understand reuse and replacement of Ipas MVA aspirators and cannulae. Qualitative interviews focused on procurement and replacement of Ipas MVA instruments. RESULTS: The authors interviewed 352 health care providers from nine countries from 2019 to 2021. Providers reported reusing MVA instruments an average of 34.4 times (standard deviation, 45). The reuse averages ranged from one time (Democratic Republic of the Congo) to 500 times (India), with figures varying between providers within the same country. Instrument malfunctioning rather than a specific number of uses drove reuse and subsequent replacement. The decision to replace was most commonly made by the provider during use. Half of the providers said that they knew of no issues with the supply chain, and 85% said they were always able to replace Ipas MVA instruments when needed. CONCLUSION: Tracking reuse of MVA instruments was uncommon at participating providers' health facilities. Providers' estimates revealed great variability in reuse frequency and tracking procedures.

RESUMEN

In response to the cessation of in-person prenatal education services during the COVID-19 pandemic, we adapted an evidence-based curriculum to a live virtual format entitled Ready, Set, Baby Live COVID-19 Edition (RSB Live). In a sample of 146 pregnant people, participation in RSB Live was associated with high levels of knowledge about the benefits of breastfeeding, early infant hunger cues, and recommended maternity care practices, as well as high levels of satisfaction with adaptations to the session's content and virtual delivery. Participation was also associated with a significant increase in prenatal breastfeeding intention, a known predictor of breastfeeding outcomes. This study supports live, virtual education with a standardized curriculum as an effective and acceptable means of providing prenatal education.

RESUMEN

HIV infection has transitioned from an acute, fatal disease to a chronic one managed by antiretroviral therapy. Thus, the aging population of people living with HIV (PLWH) continues to expand. HIV infection results in a dysregulated immune system, wherein CD4+ T cells are depleted, particularly in the gastrointestinal tract, disrupting the gut epithelial barrier. Long-term HIV infection is associated with chronic inflammation through potentially direct mechanisms caused by viral replication or exposure to viral proteins and indirect mechanisms resulting from increased translocation of microbial products from the intestine or exposure to antiretroviral therapy. Chronic inflammation (as marked by IL [interleukin]-6 and CRP [C-reactive protein]) in PLWH promotes endothelial cell dysfunction and atherosclerosis. PLWH show significantly increased rates of cardiovascular disease, such as myocardial infarction (risk ratio, 1.79 [95% CI, 1.54-2.08]) and stroke (risk ratio, 2.56 [95% CI, 1.43-4.61]). In addition, PLWH have increased levels of the coagulation biomarker D-dimer and have a two to ten-fold increased risk of venous thromboembolism compared with the general population. Several small clinical trials analyzed the effect of different antithrombotic agents on platelet activation, coagulation, inflammation, and immune cell activation. Although some markers for coagulation were reduced, most agents failed to reduce inflammatory markers in PLWH. More studies are needed to understand the underlying mechanisms driving inflammation in PLWH to create better therapies for lowering chronic inflammation in PLWH. Such therapies can potentially reduce atherosclerosis, cardiovascular disease, and thrombosis rates in PLWH and thus overall mortality in this population.

RESUMEN

Bladder pain syndrome (BPS)/interstitial cystitis (IC) is a urologic, chronic pelvic pain syndrome characterized by pelvic pain, pressure, or discomfort with urinary symptoms. Symptom exacerbation (flare) is common with multiple, perceived triggers including stress. Multiple transient receptor potential (TRP) channels (TRPA1, TRPV1, TRPV4) expressed in the bladder have specific tissue distributions in the lower urinary tract (LUT) and are implicated in bladder disorders including overactive bladder (OAB) and BPS/IC. TRPV4 channels are strong candidates for mechanosensors in the urinary bladder and TRPV4 antagonists are promising therapeutic agents for OAB. In this perspective piece, we address the current knowledge of TRPV4 distribution and function in the LUT and its plasticity with injury or disease with an emphasis on BPS/IC. We review our studies that extend the knowledge of TRPV4 in urinary bladder function by focusing on (i) TRPV4 involvement in voiding dysfunction, pelvic pain, and non-voiding bladder contractions in NGF-OE mice; (ii) distention-induced luminal ATP release mechanisms and (iii) involvement of TRPV4 and vesicular release mechanisms. Finally, we review our lamina propria studies in postnatal rat studies that demonstrate: (i) the predominance of the TRPV4+ and PDGFRα+ lamina propria cellular network in early postnatal rats; (ii) the ability of exogenous mediators (i.e., ATP, TRPV4 agonist) to activate and increase the number of lamina propria cells exhibiting active Ca2+ events; and (iii) the ability of ATP and TRPV4 agonist to increase the rate of integrated Ca2+ activity corresponding to coupled lamina propria network events and the formation of propagating wavefronts.

RESUMEN

Lamina propria interstitial cells that express the tyrosine kinase receptor, platelet-derived growth factor receptor alpha (PDGFRα) may play a role in urinary sensory signaling. Imatinib mesylate, also referred to as imatinib, is a tyrosine kinase inhibitor that can inhibit PDGFRα and has been widely used in urological research. We evaluated the functional effects of imatinib administration (via oral gavage or intravesical infusion) with two different experimental designs (prevention and treatment), in a cyclophosphamide (CYP)-induced cystitis (acute, intermediate, and chronic), male and female rodent model using conscious cystometry and somatic sensitivity testing. Imatinib significantly (0.0001 ≤ p ≤ 0.05) decreased voiding frequency and increased bladder capacity in acute CYP-induced cystitis, by the prevention (females) and treatment (females and males) designs. Imatinib was not effective in preventing or treating intermediate or chronic CYP-induced cystitis in either sex. Interestingly, in the prevention experiments, imatinib administration increased (0.0001 ≤ p ≤ 0.01) voiding frequency and decreased bladder capacity in control mice. However, in the treatment experiments, imatinib administration decreased (0.01 ≤ p ≤ 0.05) voiding frequency and increased bladder capacity in control mice. Bladder function improvements observed with imatinib treatment in acute CYP-induced cystitis mice remained and additionally improved with a second dose of imatinib 24 hours after CYP treatment. Imatinib administration did not affect pelvic somatic sensitivity in female mice with acute CYP-induced cystitis. Our studies suggest that (1) imatinib improves bladder function in mice with acute CYP-induced cystitis with a prevention and treatment design and (2) interstitial cells may be a useful target to improve bladder function in cystitis.

RESUMEN

Imatinib mesylate is a tyrosine kinase inhibitor that inhibits platelet-derived growth factor receptor (PDGFR)-α, -ß, stem cell factor receptor (c-KIT), and BCR-ABL. PDGFRα is expressed in a subset of interstitial cells in the lamina propria (LP) and detrusor muscle of the urinary bladder. PDGFRα + interstitial cells may contribute to bladder dysfunction conditions such as interstitial cystitis/bladder pain syndrome (IC/BPS) or overactive bladder (OAB). We have previously demonstrated that imatinib prevention via oral gavage or treatment via intravesical infusion improves urinary bladder function in mice with acute (4 hour, h) cyclophosphamide (CYP)-induced cystitis. Here, we investigate potential underlying mechanisms mediating the bladder functional improvement by imatinib using a prevention or treatment experimental design. Using qRT-PCR and ELISAs, we examined inflammatory mediators (NGF, VEGF, BDNF, CCL2, IL-6) previously shown to affect bladder function in CYP-induced cystitis. We also examined the distribution of phosphorylated (p) ERK and pAKT expression in the LP with immunohistochemistry. Imatinib prevention significantly (0.0001 ≤ p ≤ 0.05) reduced expression for all mediators examined except NGF, whereas imatinib treatment was without effect. Imatinib prevention and treatment significantly (0.0001 ≤ p ≤ 0.05) reduced pERK and pAKT expression in the upper LP (U. LP) and deeper LP (D. LP) in female mice with 4 h CYP-induced cystitis. Although we have previously demonstrated that imatinib prevention or treatment improves bladder function in mice with cystitis, the current studies suggest that reductions in inflammatory mediators contribute to prevention benefits of imatinib but not the treatment benefits of imatinib. Differential effects of imatinib prevention or treatment on inflammatory mediators may be influenced by the route and frequency of imatinib administration and may also suggest other mechanisms (e.g., changes in transepithelial resistance of the urothelium) through which imatinib may affect urinary bladder function following CYP-induced cystitis.

RESUMEN

Policy surveillance offers a novel and important method for comparing law across jurisdictions. We used policy surveillance to examine abortion laws across the globe. Self-managed abortion, which generally takes place outside formal healthcare settings, is increasing in prevalence and can be safe. We analysed provisions that do not account for the prevalence of self-managed abortion and evidence of its safety. Such provisions require that abortion take place in a formal healthcare setting. We also analysed criminal penalties for non-compliance. Our method included development of a legal framework, an iterative process of refining coding schemes and procedures, and rigorous quality control. We limited our analysis to liberal abortion laws for two reasons. Abortion laws globally trend towards less restrictive. In addition, we aimed to focus on how laws relate to abortion outside a formal healthcare setting specifically and excluded laws that prohibit abortion more broadly. We found that in all countries with liberal national abortion laws, the law permits only healthcare professionals or trained health workers to perform legal abortion and the majority require the abortion to take place in a specified health facility. With policy surveillance methods we can illuminate characteristics of law across many jurisdictions and the need for widespread reform, toward laws that reflect scientific evidence and the way people have abortions.

RESUMEN

Kaposi sarcoma (KS)-associated herpesvirus (KSHV/HHV-8) was first sequenced from the body cavity (BC) lymphoma cell line, BC-1, in 1996. Few other KSHV genomes have been reported. Our knowledge of sequence variation for this virus remains spotty. This study reports additional genomes from historical US patient samples and from African KS biopsies. It describes an assay that spans regions of the virus that cannot be covered by short read sequencing. These include the terminal repeats, the LANA repeats, and the origins of replication. A phylogenetic analysis, based on 107 genomes, identified three distinct clades; one containing isolates from USA/Europe/Japan collected in the 1990s and two of Sub-Saharan Africa isolates collected since 2010. This analysis indicates that the KSHV strains circulating today differ from the isolates collected at the height of the AIDS epidemic. This analysis helps experimental designs and potential vaccine studies.

RESUMEN

PURPOSE: To evaluate which side effects of chemotherapy are considered most burdensome by patients with cancer, identify which health care professionals pay most attention to symptoms associated with chemotherapy-induced myelosuppression (CIM) from the patient perspective, and capture the "patient voice" describing how CIM impacts their daily lives. PARTICIPANTS AND METHODS: Online survey of participants with breast, lung, or colorectal cancer who had received chemotherapy within the past 12 months and experienced ≥1 episode of CIM in the past year. Participants were asked to answer close-ended questions and provide qualitative responses to: "In your own words, please describe how side effects from myelosuppression have impacted your life." RESULTS: Among 301 survey participants, fatigue was the most frequently reported side effect of chemotherapy; 55% of participants rated fatigue as highly bothersome (9 or 10 on a 1-10 scale of "bothersomeness"). Participants rated symptoms associated with CIM, including fatigue, weakened immune system (infections), bleeding and/or bruising, and shortness of breath, as being as bothersome as other side effects of chemotherapy, including alopecia, neuropathy, and nausea/vomiting. Overall, 24-43% of participants thought that CIM and its symptoms had a negative impact on their daily lives, including their ability to complete tasks at home and work, and to socialize. Qualitative responses supported these findings; participants highlighted that CIM-related symptoms, particularly fatigue and fear of infections, affected their ability to be physically active, complete work, or continue meaningful relationships with friends and family. CONCLUSION: Participants described a real-world impact of CIM that often isolates them from family and friends, and means that they are unable to work or perform tasks of daily living. Using measures that help patients to recognize and communicate the signs and symptoms of CIM might increase the likelihood of maintaining daily lives as close to normal as possible, during and after chemotherapy treatment.

RESUMEN

INTRODUCTION: Patient-reported outcome measures (PROMs) are used to capture patient perspectives in disease assessment. The objective of this study was to capture feedback about commonly used PROMs for spondyloarthritis (SpA) through semi-structured group discussions with individuals diagnosed with psoriatic arthritis (PsA) or ankylosing spondylitis (AS). The goal was to identify PROM content that most resonated with patient experiences and is therefore suitable for implementation in SpA clinical practice. METHODS: Semi-structured tasks and probes were designed to elicit qualitative patient feedback on several general health and disease-specific PROMs. During a series of in-person and telephone meetings, participants with PsA or AS were asked to identify content that resonated with them and to identify items that may not have captured their personal experiences living with their disease. Both individualized and small group review and concept elicitation were captured after participant review of PROMs. RESULTS: Both PsA and AS participants identified concepts that reflected their experiences living with a chronic disease, including fatigue, isolation, depression, inter-personal relationships, and sexual intimacy. Constructs incorporated into existing PROMs, such as pain, physical function, ability to perform activities of daily living, and stiffness, were also identified as important to participants. There were a few qualitative differences in participant perceptions about what they would like to see addressed by PROMs. For example, AS participants said that they would like to see PROMs elicit feedback about their experiences with pelvic and chest pain (e.g., as a result of chest inflammation/tenderness and chest expansion). PsA participants felt that PROMs should include measures about the embarrassment and shame that they experience as well as the impact of PsA on their daily lives. CONCLUSION: Results of these qualitative assessments suggest that PROMs should be incorporated more frequently in outpatient settings to help improve the quality of decision-making conversations between patients and their healthcare providers. Participants indicated that constructs such as isolation, depression, fatigue, and relationships with others were critical to inform healthcare professionals about the patient experience of living with their disease.

RESUMEN

Stress causes symptom exacerbation in functional disorders of the urinary bladder. However, the potential mediators and underlying mechanisms of stress effects on micturition reflex function are unknown. We have characterized PACAP (Adcyap1) and PAC1 receptor (Adcyap1r1) signaling in stress-induced urinary bladder dysfunction in mice. We determined PACAP and PAC1 transcripts and protein expressions in the urinary bladder and lumbosacral dorsal root ganglia (DRG) and spinal cord in repeated variate stress (RVS) or control mouse (handling only) groups. RVS in mice significantly (p ≤ 0.01) increased serum corticosterone and urinary bladder NGF content and decreased weight gain. PACAP and PAC1 mRNA and protein were differentially regulated in lower urinary tract tissues with changes observed in lumbosacral DRG and spinal cord but not in urinary bladder. RVS exposure in mice significantly (p ≤ 0.01) increased (2.5-fold) voiding frequency as determined using conscious cystometry. Intrabladder administration of the PAC1 receptor antagonist, PACAP(6-38) (300 nM), significantly (p ≤ 0.01) increased infused volume (1.5-2.7-fold) to elicit a micturition event and increased the intercontraction interval (i.e., decreased voiding frequency) in mice exposed to RVS and in control mice, but changes were smaller in magnitude in control mice. We also evaluated the effect of PAC1 blockade at the level of the urinary bladder on pelvic sensitivity in RVS or control mouse groups using von Frey filament testing. Intrabladder administration of PACAP(6-38) (300 nM) significantly (p ≤ 0.01) reduced pelvic sensitivity following RVS. PACAP/receptor signaling in the CNS and PNS contributes to increased voiding frequency and pelvic sensitivity following RVS and may represent a potential target for therapeutic intervention.

RESUMEN

INTRODUCTION: Chemotherapy-induced myelosuppression (CIM) is one of the most common dose-limiting complications of cancer treatment, and is associated with a range of debilitating symptoms that can significantly impact patients' quality of life. The purpose of this study was to understand patients' perspectives on how the side effects of CIM are managed in routine clinical practice. METHODS: An online survey was conducted of participants with breast, lung, or colorectal cancer who had received chemotherapy treatment within the past 12 months, and had experienced at least one episode of myelosuppression in the past year. The survey was administered with predominantly close-ended questions, and lay definitions of key terms were provided to aid response selection. RESULTS: Of 301 participants who completed the online survey, 153 (51%) had breast cancer, 100 (33%) had lung cancer, and 48 (16%) had colorectal cancer. Anemia, neutropenia, lymphopenia, and thrombocytopenia were reported by 61%, 59%, 37%, and 34% of participants, respectively. Most participants (79%) reported having received treatment for CIM, and 64% of participants recalled chemotherapy dose modifications as a result of CIM. Although most participants believed their oncologist was aware of the side effects of CIM, and treated them quickly, 30% of participants felt their oncologists did not understand how uncomfortable they were due to the side effects of CIM. Overall, 88% of participants considered CIM to have a moderate or major impact on their lives. CONCLUSION: The data highlight that despite the various methods used to address CIM, and the patient-focused approach of oncologists, the real-world impact of CIM on patients is substantial. Improving communication between patients and health care providers may help improve patients' understanding of CIM, and foster shared decision-making in terms of treatment. Additional insights from patients should be obtained to further elucidate the totality of life burden associated with CIM.


This study looked at people with cancer who received chemotherapy and developed a condition where their bone marrow activity was reduced, called myelosuppression. This meant they had fewer red blood cells that carry oxygen around the body, white blood cells that help fight infections, and platelets that help the blood to clot. The researchers wanted to understand how chemotherapy-induced myelosuppression affects peoples' lives and their cancer treatment, and people's experiences of treatment for myelosuppression. Overall, 301 people in the USA with breast, lung, or large bowel (colorectal) cancer completed an online survey. They had all received chemotherapy in the last year, and had myelosuppression at least once during their treatment. The survey showed that around 8 in 10 people (79%) had to be treated for myelosuppression, and around 7 in 10 people (73%) felt they received treatment for myelosuppression quickly. Chemotherapy was delayed, reduced, or stopped because of myelosuppression in around 6 in 10 people (64%). Around 3 in 10 people (30%) felt their oncologist did not understand the discomfort that myelosuppression caused them, and around 9 in 10 people (88%) felt that myelosuppression made their quality of life worse. The researchers concluded that because myelosuppression impacts peoples' lives and their ability to keep receiving chemotherapy to treat their cancer, effective prevention and treatment for this condition are important. Better communication between people and their health care teams could help them to understand how people experience myelosuppression and make plans for treatment together.

RESUMEN

Transient receptor potential vanilloid family member 4 (TRPV4) transcript and protein expression increased in the urinary bladder and lumbosacral dorsal root ganglia of transgenic mice with chronic urothelial overexpression of nerve growth factor (NGF-OE). We evaluated the functional role of TRPV4 in bladder function with open-outlet cystometry, void spot assays, and natural voiding (Urovoid) assays with the TRPV4 antagonist HC-067047 (1 µM) or vehicle in NGF-OE and littermate wild-type (WT) mice. Blockade of TRPV4 at the level of the urinary bladder significantly (P ≤ 0.01) increased the intercontraction interval (2.2-fold) and void volume (2.6-fold) and decreased nonvoiding contractions (3.0-fold) in NGF-OE mice, with lesser effects (1.3-fold increase in the intercontraction interval and 1.3-fold increase in the void volume) in WT mice. Similar effects of TRPV4 blockade on bladder function in NGF-OE mice were demonstrated with natural voiding assays. Intravesical administration of HC-067047 (1 µM) significantly (P ≤ 0.01) reduced pelvic sensitivity in NGF-OE mice but was without effect in littermate WT mice. Blockade of urinary bladder TRPV4 or intravesical infusion of brefeldin A significantly (P ≤ 0.01) reduced (2-fold) luminal ATP release from the urinary bladder in NGF-OE and littermate WT mice. The results of the present study suggest that TRPV4 contributes to luminal ATP release from the urinary bladder and increased voiding frequency and pelvic sensitivity in NGF-OE mice.

RESUMEN

Background: Psoriasis (PsO) is a chronic inflammatory skin disorder that may be associated with comorbidities, including inflammatory bowel disease (IBD), given common immunopathogenic mechanisms. Whether PsO patients are more likely to suffer from gastrointestinal (GI) signs and symptoms has not been well-characterized. Understanding their prevalence in PsO patients may inform strategies to evaluate for GI signs and symptoms, screen for those at risk for IBD, and guide choice of therapy. Objective: To assess the prevalence of GI signs and symptoms in patients with moderate-to-severe PsO. Methods: An Internet-based survey was conducted to evaluate GI signs and symptoms in patients with self-reported moderate-to-severe PsO and non-PsO controls. The impact of PsO severity and presence of psoriatic arthritis (PsA) [self-reported and/or screened positive on the Psoriatic Arthritis Screening and Evaluation (PASE) questionnaire] on prevalence of GI signs and symptoms was also assessed. The survey included questions about PsO, comorbidities, demographics, and GI signs and symptoms. Questions related to GI signs and symptoms were used to calculate a modified CalproQuest* score to identify patients at increased risk for IBD. Results: Survey responses were collected from 740 PsO patients and 1411 non-PsO controls. With the exception of age, demographics were generally comparable between groups. All six GI signs and symptoms assessed (belly pain, feeling full/bloated, diarrhea, mucus in stool, blood in stool, and unintentional weight loss) were more prevalent in PsO patients compared with non-PsO controls, and a higher proportion of PsO patients also had a positive CalproQuest* result. In addition, both more severe PsO and concomitant PsA were associated with a higher prevalence of GI signs and symptoms and a positive CalproQuest*. Conclusions: This study suggests that PsO patients, including those with PsA, have a higher prevalence of GI signs and symptoms. Physicians should recognize and consider this concern in PsO patient management. J Drugs Dermatol. 2018;17(12):1298-1308.

RESUMEN

INTRODUCTION: The management of acute postoperative pain remains a significant challenge for physicians. Poorly controlled postoperative pain is associated with poorer overall outcomes. METHODS: Between April and May 2017, physicians from an online database who regularly prescribe intravenous (IV) medications for acute postoperative pain completed a 47-question survey on topics such as patient demographics, IV analgesia preferences, factors that influence prescribing decisions, and the challenges and unmet needs for the treatment of acute postoperative pain. RESULTS: Of 501 surveyed physicians, 55% practiced in community hospitals, 60% had been in practice for > 10 years, and 60% were surgeons. The three categories of IV pain medications most likely to be prescribed to patients with moderate-to-severe pain immediately after surgery were morphine, hydromorphone, or fentanyl (95.8% of respondents); COX-2 inhibitors or nonsteroidal anti-inflammatory drugs (73.7%); and acetaminophen (60.5%). Past clinical experience (81.6%), surgery type (78.2%), and onset of analgesia (67.1%) were practice-related factors that most determined their medication choice. Key patient-related risk factors, such as avoidance of medication-related adverse events (AEs), each influenced prescription decisions in > 75.0% of physicians. Nausea and vomiting were among the most common challenges associated with postoperative pain management (76.2 and 60.3%, respectively), and avoidance of analgesic medication-related AEs was among the three most influential patient-related factors that determined prescribing decision (75%). Physicians reported the top unmet need for acute pain management in patients experiencing moderate-to-severe postoperative pain was more medications with fewer side effects (i.e., nausea, vomiting, and respiratory depression; 80.7%). CONCLUSIONS: Opioids remain an integral component of multimodal acute analgesic therapy for acute postoperative pain in hospitalized patients. The use of all IV analgesic medications is limited by concerns over AEs, particularly with opioids and in high-risk patients. There remains a key unmet need for effective analgesic medications that are associated with a lower risk of AEs. FUNDING: Trevena, Inc.

RESUMEN

OBJECTIVES: The rapid spread of infections due to antibiotic-resistant, Gram-negative bacteria in Europe and surrounding regions requires a heightened level of awareness among physicians within their practice settings. METHODS: We surveyed 800 physicians who treat these infections across France, Germany, Spain, Italy, and Russia to assess their awareness of best management approaches. RESULTS: We found that more than two-thirds do not consider themselves highly aware of best management practices. The respondents are facing these resistant infections as evidenced by the antibiotics they report using and their stated interest in newer agents. Respondents indicated that precious time is lost waiting for culture results, but also said they will need more information about accuracy, use, and costs for adopting rapid molecular testing. CONCLUSIONS: The survey further identified the need for treatment guidelines and clinical decision support tools that can be applied at the bedside.
