Nocturnal hypoxia and age-related macular degeneration.

BACKGROUND: Nocturnal hypoxia is common, under-diagnosed and is found in the same demographic at risk of age-related macular degeneration (AMD). The objective of this study was to determine any association between nocturnal hypoxia and AMD, its severity, and the high-risk sub-phenotype of reticular pseudodrusen (RPD). METHODS: This cross-sectional study included participants aged ≥50 years with AMD, or normal controls, exclusive of those on treatment for obstructive sleep apnoea. All participants had at home, overnight (up to 3 nights) pulse oximetry recordings and multimodal imaging to classify AMD. Classification of Obstructive Sleep Apnea (OSA) was determined based on oxygen desaturation index [ODI] with mild having values of 5-15 and moderate-to-severe >15. RESULTS: A total of 225 participants were included with 76% having AMD, of which 42% had coexistent RPD. Of the AMD participants, 53% had early/intermediate AMD, 30% had geographic atrophy (GA) and 17% had neovascular AMD (nAMD). Overall, mild or moderate-to-severe OSAwas not associated with an increased odds of having AMD nor AMD with RPD (p ≥ 0.180). However, moderate-to-severe OSA was associated with increased odds of having nAMD (odds ratio = 6.35; 95% confidence interval = 1.18 to 34.28; p = 0.032), but not early/intermediate AMD or GA, compared to controls (p ≥ 0.130). Mild OSA was not associated with differences in odds of having AMD of any severity (p ≥ 0.277). CONCLUSIONS: There was an association between nocturnal hypoxia as measured by the ODI and nAMD. Hence, nocturnal hypoxia may be an under-appreciated important modifiable risk factor for nAMD.

Substance use as subtext to health narratives: Identifying opportunities for improving care from community member perspectives.

OBJECTIVE: To analyze patient and caregiver narratives addressing experiences related to substance use and substance use disorder (SUD). METHODS: Thirty audio-narratives from the MyPaTH Story Booth archive addressed substance use between 5/20/2016 and 2/24/21. Two coders established an average Cohen's kappa statistics of 0.81 over 16 stories. The primary coder coded and summarized additional narratives and conducted content and thematic analyses. The final analytic sample addressed perspectives of individuals with SUD, caregivers for individuals with SUD and individuals who have used opioids to manage pain. RESULTS: Storytellers' average age was 51, 55 % were female and 85 % were white. Participants with SUD and caregivers described frustration with the current treatment system, reported limited treatment of SUD in medical settings, and noted relying on community-based groups for ongoing care. Individuals with chronic pain felt stigmatized and resented perceived restrictions on pain treatment due to the opioid epidemic. CONCLUSIONS: Unstructured narratives provide insights into the lived experiences of people impacted by SUD. Participants reported struggling with the effects of SUD and failing to find adequate treatment from the medical system. Stories highlight SUD-related stigma. PRACTICE IMPLICATIONS: Understanding patient and caregiver perspectives related to SUD can be a critical step towards developing effective interventions.

Community pharmacists' attitudes toward and practice of pharmacy-based harm reduction services in Pittsburgh, PA: a descriptive survey.

BACKGROUND: In Pittsburgh, PA, legal changes in recent decades have set the stage for an expanded role for community pharmacists to provide harm reduction services, including distributing naloxone and non-prescription syringes (NPS). In the wake of the syndemics of the COVID-19 pandemic and worsening overdose deaths from synthetic opioids, we examine knowledge, attitudes, and practices of harm reduction services among community pharmacists in Pittsburgh and identify potential barriers of expanded pharmacy-based harm reduction services. METHODS: We provided flyers to 83 community pharmacies within a 5-mile radius of the University of Pittsburgh Medical Center to recruit practicing community pharmacists to participate in an anonymous electronic survey. We used a 53-question Qualtrics survey consisting of multiple-choice, 5 or 6 point-Likert scale, and open-ended questions adapted from 5 existing survey instruments. Survey measures included demographics, knowledge, attitudes, and practices of harm reduction services (specifically naloxone and NPS provision), and explored self-reported barriers to future implementation. Data was collected July-August 2022. We conducted descriptive analysis using frequencies and proportions reported for categorical variables as well as means and standard deviations (SD) for continuous variables. We analyzed open-ended responses using inductive content analysis. RESULTS: Eighty-eight community pharmacists responded to the survey. 90% of participants agreed pharmacists had a role in overdose prevention efforts, and 92% of participants had previously distributed naloxone. Although no pharmacists reported ever refusing to distribute naloxone, only 29% always provided overdose prevention counseling with each naloxone distributed. In contrast, while 87% of participants had positive attitudes toward the usefulness of NPS for reducing disease, only 73% of participants ever distributed NPS, and 54% had refused NPS to a customer. Participants endorsed a lack of time and concerns over clientele who used drugs as the most significant barriers to offering more comprehensive harm reduction services. CONCLUSIONS: Our findings highlight that while most community pharmacists have embraced naloxone provision, pharmacy policies and individual pharmacists continue to limit accessibility of NPS. Future expansion efforts for pharmacy-based harm reduction services should not only address the time and labor constraints identified by community pharmacists, but also fear-based policy and stigma toward people who inject drugs and harm reduction more broadly.

Study Protocol for Pain Self-Management and Patient-Oriented Buprenorphine Dosing for Pain and Retention in Office-Based Opioid Treatment: A Hybrid Type 1, 2 × 2 Factorial Randomized Controlled Trial.

Chronic pain is a significant factor for patients with opioid use disorder (OUD) contributing to suboptimal retention in buprenorphine treatment, which is a crucial predictor of long-term health outcomes. This study aims to address the critical need for effective interventions targeting chronic pain management within office-based opioid treatment (OBOT) programs. We are conducting a multisite, hybrid type 1, 2 × 2 factorial randomized clinical trial to determine the effectiveness of 2 novel interventions, pain self-management (PSM) and patient-oriented buprenorphine dosing (POD), to decrease pain interference and improve retention in buprenorphine treatment. PSM, a manualized and customizable approach delivered through individual and peer-led group sessions, aims to decrease pain-related symptoms and quality of life. POD involves split dosing of buprenorphine to extend the duration of analgesia to better match its duration of efficacy at managing OUD symptoms, leading to improved retention in buprenorphine treatment. Eligible participants will be randomized into 1 of 4 groups: (1) PSM + POD, (2) PSM + Standard Buprenorphine Dosing, (3) Usual Care + POD, or (4) Usual Care + Standard Buprenorphine Dosing. Usual Care refers to usual care for chronic pain and Standard Buprenorphine Dosing refers to the participant's current dosing regimen. Secondary objectives encompass overall pain reduction, decreased opioid use, improved pain symptom management, and exploration of implementation strategies. The supplemental approved protocol provides comprehensive insights into the procedures and variables being investigated. As part of the HEAL Initiative®-funded Integrative Management of Chronic Pain and OUD for Whole Recovery (IMPOWR) network, this study aims to fill gaps in behavioral and medication treatments for individuals with co-occurring chronic pain and OUDs, improving pain management and retention in care. Successful outcomes from this trial may inform future larger trials, offering essential evidence for implementation considerations and reimbursement decisions.

Venom Hypersensitivity.

Stinging insects are a frequent cause of local and systemic hypersensitivity reactions, including anaphylaxis. For those with a history of life-threatening anaphylaxis, venom immunotherapy is effective, safe, and can be life-saving. Arachnids are a much less common source of envenomation through bites or stings and are less likely to cause a hypersensitivity reaction. However, recognizing the clinical manifestations when they do present is important for accurate diagnosis and treatment, and, when indicated, consideration of other diagnoses.

Optimizing evidence-based practice implementation: a case study on simulated patient protocols in long-term opioid therapy.

BACKGROUND: Substantial work has been done to update or create evidence-based practices (EBPs) in the changing health care landscape. However, the success of these EBPs is limited by low levels of clinician implementation. OBJECTIVE: The goal of this study is to describe the use of standardized/simulated patient/person (SP) methodology as a framework to develop implementation bundles to increase the effectiveness, sustainability, and reproducibility of EBPs across health care clinicians. DESIGN: We observed 12 clinicians' first-time experiences with six unique decision-making algorithms, developed previously using rigorous Delphi methods, for use with patients exhibiting concerning behaviors associated with long-term opioid therapy (LTOT) for chronic pain. Clinicians were paired with two SPs trained to portray individuals with one of the concerning behaviors addressed by the algorithms in a telehealth environment. The SP evaluations were followed by individual interviews, guided by the Consolidated Framework for Implementation Research (CFIR), with each of the clinician participants. PARTICIPANTS: Twelve primary care clinicians and 24 SPs in Western Pennsylvania. MAIN MEASUREMENT: The primary outcome was identifying likely facilitators for the successful implementation of the EBP using the SP methodology. Our secondary outcome was to assess the feasibility of using SPs to illuminate likely implementation barriers and facilitators. RESULTS: The SP portrayal illuminated factors that were pertinent to address in the implementation bundle. SPs were realistic in their portrayal of patients with concerning behaviors associated with LTOT for chronic pain, but clinicians also noted that their patients in practice may have been more aggressive about their treatment plan. CONCLUSIONS: SP simulation provides unique opportunities for obtaining crucial feedback to identify best practices in the adoption of new EBPs for high-risk patients. SETTING: Zoom simulated patient evaluations.

Is there potential for estradiol receptor signaling in lophotrochozoans?

Estrogen receptors (ERs) are thought to be the ancestor of all steroid receptors and are present in most lophotrochozoans studied to date, including molluscs, annelids, and rotifers. A number of studies have investigated the functional role of estrogen receptors in invertebrate species, although most are in molluscs, where the receptor is constitutively active. In vitro experiments provided evidence for ligand-activated estrogen receptors in annelids, raising important questions about the role of estrogen signalling in lophotrochozoan lineages. Here, we review the concordant and discordant evidence of estradiol receptor signalling in lophotrochozoans, with a focus on annelids and rotifers. We explore the de novo synthesis of estrogens, the evolution and expression of estrogen receptors, and physiological responses to activation of estrogen receptors in the lophotrochozoan phyla Annelida and Rotifera. Key data are missing to determine if de novo biosynthesis of estradiol in non-molluscan lophotrochozoans is likely. For example, an ortholog for the CYP11 gene is present, but confirmation of substrate conversion and measured tissue products is lacking. Orthologs CYP17 and CYP19 are lacking, yet intermediates or products (e.g. estradiol) in tissues have been measured. Estrogen receptors are present in multiple species, and for a limited number, in vitro data show agonist binding of estradiol and/or transcriptional activation. The expression patterns of the lophotrochozoan ERs suggest developmental, reproductive, and digestive roles but are highly species dependent. E2 exposures suggest that lophotrochozoan ERs may play a role in reproduction, but no strong dose-response relationship has been established. Therefore, we expect most lophotrochozoan species, outside of perhaps platyhelminths, to have an ER but their physiological role remains elusive. Mining genomes for orthologs gene families responsible for steroidogenesis, coupled with in vitro and in vivo studies of the steroid pathway are needed to better assess whether lophotrochozoans are capable of estradiol biosynthesis. One major challenge is that much of the data are divided across a diversity of species. We propose that the polychaetes Capitella teleta or Platyneris dumerilii, and rotifer Brachionus manjavacas may be strong species choices for studies of estrogen receptor signalling, because of available genomic data, established laboratory culture techniques, and gene knockout potential.

Outcomes of elective and emergency surgical repair of incisional hernia: a comparative observational study.

PURPOSE: Incisional hernia (IH) is a common complication following abdominal surgery. Surgical repair of IH is associated with the alleviation of symptoms and improvement of quality of life. Operative intervention can pose a significant burden to the patient and healthcare facilities. This study aims to describe and compare outcomes of elective and emergency surgical repair of IH. METHODS: This study is a single-centre comparative retrospective study including patients who had repair of IH. Patients were divided into Group I (Emergency) and Group II (Elective), and a comparison was conducted between them. RESULTS: Two hundred sixty-two patients were identified with a mean age of 61.8 ± 14.2 years, of which 152 (58%) were females. The mean BMI was 31.6 ± 7.2 kg/m2. More than 58% had at least one comorbidity. 169 (64.5%) patients had an elective repair, and 93 (35.5%) had an emergency repair. Patients undergoing emergency repair were significantly older and had higher BMI, p = 0.031 and p = 0.002, respectively. The significant complication rate (Clavien-Dindo III and IV) was 9.54%. 30 and 90-day mortality rates were 2.3% (n = 6) and 2.68% (n = 7), respectively. In the emergency group, the overall complications, 30-day and 90-day mortality rates were significantly higher than in the elective group, p ≤ 0.001, 0.002 and 0.001, respectively. Overall, 42 (16.1%) developed wound complications, 25 (9.6%) experienced a recurrence, and 41 (15.71%) were readmitted within 90 days, without significant differences between the two groups. CONCLUSION: Patients who underwent emergency repair were significantly older and had a higher BMI than the elective cases. Emergency IH repair is associated with higher complication rates and mortality than elective repair.

Association between inflammation and post-intensive care syndrome: a systematic review.

Post-intensive care syndrome describes the physical, cognitive and emotional symptoms which persist following critical illness. At present there is limited understanding of the pathological mechanisms contributing to the development of post-intensive care syndrome. The aim of this systematic review was to synthesise current evidence exploring the association between inflammation and features of post-intensive care syndrome in survivors of critical illness. Relevant databases were systematically searched for studies of human participants exposed to critical illness. We sought studies that reported results for biomarkers with an identified role in the pathophysiology of inflammation obtained at any time-point in the patient journey and an outcome measure of any feature of post-intensive care syndrome at any point following hospital discharge. We included 32 studies, with 23 in the primary analysis and nine in a brain injury subgroup analysis. In the primary analysis, 47 different biomarkers were sampled and 44 different outcome measures were employed. Of the biomarkers which were sampled in five or more studies, interleukin-8, C-reactive protein and interleukin-10 most frequently showed associations with post-intensive care syndrome outcomes in 71%, 62% and 60% of studies, respectively. There was variability in terms of which biomarkers were sampled, time-points of sampling and outcome measures reported. Overall, there was mixed evidence of a potential association between an inflammatory process and long-term patient outcomes following critical illness. Further high-quality research is required to develop a longitudinal inflammatory profile of survivors of critical illness over the recovery period and evaluate the association with outcomes.

Co-delivery of HIV pre-exposure prophylaxis (PrEP) and HIV testing among publicly insured adolescents and young adults (AYA) receiving medication for opioid use disorder (MOUD).

BACKGROUND: Low rates of HIV pre-exposure prophylaxis (PrEP) prescribing contribute to the disproportionate burden of HIV in the United States. Among adolescent and young adults (AYA) with opioid use disorder, HIV testing and PrEP co-prescription rates are poorly characterized. METHODS: We performed a retrospective analysis involving deidentified data from Philadelphia's Medicaid beneficiaries ages 16-29 years who were prescribed medication for opioid use disorder (MOUD) from 2015 to 2020 and continuously Medicaid-enrolled for ≥6 months prior to that prescription. After identifying the presence of a qualifying diagnosis signifying a PrEP indication, we examined the outcome of appropriate PrEP co-prescriptions and HIV testing using generalized estimating equations (GEE) modeling. RESULTS: We identified 795 AYA Medicaid beneficiaries with 1269 qualified treatment episodes. We calculated a PrEP prescribing rate of 29.47 per 1000 person-years among AYA receiving MOUD. The HIV testing rate was 63.47 per 1000 person-years among AYA receiving MOUD. GEE modeling revealed that individuals receiving methadone were more likely (aOR=2.62, 95% CI=1.06-6.49) to receive HIV testing within 6 months after a PrEP-qualifying diagnosis compared to those receiving other MOUD medications. Those who only saw outpatient behavioral health providers were less likely (aOR=0.48, 95% CI=0.24-0.99) to have received an HIV test within 6 months after the PrEP-qualifying diagnosis compared to those receiving inpatient behavioral health services. CONCLUSIONS: Co-prescription of PrEP and HIV testing among AYA receiving MOUD was rare in this large urban publicly insured population. Interventions are needed to increase HIV prevention services for this key population of AYA at risk for HIV infection.

Lessons learnt and best practices in scaling up an emergency transportation system to tackle maternal and neonatal mortality: a qualitative study of key stakeholders in Shinyanga, Tanzania.

OBJECTIVE: This study aimed to document lessons learnt and best practices for scaling up an innovative emergency transportation system, drawing insights from the m-mama programme implemented in Shinyanga, Tanzania. The m-mama pilot programme was implemented in phases from 2014 to 2016 in two districts and later scaled up to include all districts in Shinyanga region in 2017. The programme employed an emergency transportation system and technical and operational support of the health system to address the three delays leading to maternal and neonatal mortality. DESIGN: Cross-sectional, qualitative research with key healthcare system stakeholders from the national, regional and district levels. SETTING: The study was conducted in Kahama and Kishapu districts in Shinyanga, Tanzania. The two districts were selected purposefully to represent the programme implementation districts' rural and urban or semiurban settings. PARTICIPANTS: District, regional and national stakeholders involved in implementing the m-mama pilot programme in Shinyanga were interviewed between February and March 2022. RESULTS: Lessons learnt from implementing the m-mama programme were grouped into four key themes: community engagement, emergency transportation system, government engagement, and challenges and constraints in technical implementation. Stakeholder engagement and collaboration at all levels, community involvement in implementation, adherence to local contexts and effective government partnerships were identified as key drivers for programme success. Coordination, supervision and infrastructure enhancement were crucial in implementing the emergency transportation system. CONCLUSIONS: Facilitating community involvement, understanding the local context and adapting to existing structures can enhance programme ownership and utilisation. The government serves as the central coordinator, overseeing resource mobilisation and distribution. A well-executed and coordinated emergency transportation system holds promise in addressing delays and curbing maternal and neonatal mortality. Collaborative knowledge-sharing among implementers is essential for identifying best practices and gaining insights into practical strategies for addressing anticipated challenges.

Psychometric evaluation of the Symptom-Checklist-K-9 among U.S. working-age adults with psychiatric disabilities.

PURPOSE: The Symptom Checklist 90-Revised (SCL-90-R; Derogatis, 1992) is a widely used self-report measure of psychiatric symptoms (Prinz et al., 2013), but it is longer than many screening measures used in certain settings. Recently, a nine-item form of the SCL-90-R, the Symptom-Checklist-K-9 (SCL-K-9), has been gaining traction despite the limited research examining its psychometric properties in the United States. The purpose of this study is to conduct a psychometric evaluation of the SCL-K-9 scores in U.S. working-age adults with psychiatric disabilities. DESIGN: Six hundred and thirty participants with self-reported psychiatric disabilities completed the SCL-K-9 and other psychosocial self-report measures. Confirmatory factor analysis (CFA) was conducted to evaluate the SCL-K-9 scores' dimensionality. Coefficient omega was used to assess the scores' internal consistency. Convergent and discriminant validity were assessed by examining the strength and direction of correlation coefficients between the SCL-K-9 and other psychosocial measures. Measurement invariance across sex, age, and primary diagnostic groups was also examined. RESULTS: CFA revealed a one-factor solution with satisfactory reliability (coefficient omega = .828). Convergent validity was supported by the relatively high correlation coefficients between the SCL-K-9 with neuroticism, self-stigma, and psychiatric disability acceptance, and discriminant validity by relatively low correlation coefficients with perceived social stigma and hope. Full measurement invariance for sex and partial invariance for diagnostic groups was supported. CONCLUSIONS: Overall, this study provides preliminary reliability and validity evidence for the SCL-K-9 scores among U.S. working-age adults with psychiatric disabilities. Further investigation is warranted to support its use for research and treatment progress monitoring in recovery-oriented care. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Impaired vision in children prenatally exposed to methadone: an observational cohort study.

BACKGROUND/OBJECTIVES: To examine prevalence of failed visual assessment at 8-10 years in children born to methadone-maintained opioid dependent (MMOD) mothers and relate this to known in utero substance exposure. SUBJECTS/METHODS: Follow up of observational cohort study of methadone-exposed and comparison children matched for birthweight, gestation and postcode of residence at birth. Participants were 144 children (98 exposed, 46 comparison). Prenatal drug exposure was previously established via comprehensive maternal and neonatal toxicology. Children were invited to attend for visual assessment and casenotes were reviewed. Presence of acuity poorer than 0.2 logMAR, strabismus, nystagmus and/or impaired stereovision constituted a 'fail'. Fail rates were compared between methadone-exposed and comparison children after adjusting for known confounding variables. RESULTS: 33 children attended in person: data were also derived from casenote review for all children. After controlling for maternal reported tobacco use, methadone-exposed children were more likely to have a visual 'fail' outcome, adjusted odds ratio 2.6, 95% CI 1.1-6.2; adjusted relative risk 1.8 (95% CI 1.1-3.4). Visual 'fail' outcome rates did not differ between methadone-exposed children who had (n = 47) or had not (n = 51) received pharmacological treatment for neonatal abstinence/opioid withdrawal syndrome (NAS/NOWS); fail rate 62% vs 53% (95% CI of difference-11-27%). CONCLUSIONS: Children born to MMOD mothers are almost twice as likely as unexposed peers to have significant visual abnormalities at primary school age. Prenatal methadone exposure should be considered in the differential diagnosis of nystagmus. Findings support visual assessment prior to school entry for children with any history of prenatal opioid exposure. TRIAL REGISTRATION: The study was prospectively registered on ClinicalTrials.gov (NCT03603301), https://clinicaltrials.gov/ct2/show/NCT03603301 .

Confirmatory factor analysis of the 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS-2.0) within the clubhouse model of psychosocial rehabilitation for serious mental illness.

OBJECTIVE: The Clubhouse model (CM) for serious mental illness is a recovery-oriented and member-driven program that aims to facilitate functional recovery. Efficacy evaluation of the CM is limited by lack of uniform functional disability assessment. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS-2.0) is a widely accepted measure of functional disability, but its psychometric properties have yet to be examined within the CM. METHOD: This research sought to confirm the generic six-factor structure of the 12-item WHODAS-2.0 using retrospective administrative data from 339 adults with serious mental illness from an accredited Clubhouse. A second-order confirmatory factor analysis was conducted, followed by secondary known-groups analyses to examine whether the WHODAS-2.0 differentiates between subgroups with varying degrees of disability. RESULTS: The WHODAS-2.0 demonstrated good overall reliability. The generic six-factor structure produced nonsignificant loadings due to lack of independence between the "participation" and "getting along" factors. The items of these two factors were combined into a five-factor model, which displayed excellent fit, with all significant paths and adequate-to-strong loadings, and no correlation among errors. The WHODAS-2.0 significantly differentiated members by receipt of public assistance, employment status, and number of medical comorbidities, supporting construct validity. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: These results provide initial support for the use of the 12-item WHODAS-2.0 as a CM-related outcome measure and encourage future research of the full 36-item version. The intentional community approach of the CM is unique and may require adjustments to the factor structure of the WHODAS-2.0 by merging the "participation" and "getting along" domains.

Unidimensional versus multidimensional: A bifactor factor structure of the Self-Stigma Scale-Short (SSS-S) among U.S. adults with psychiatric disabilities.

OBJECTIVE: This study aimed to examine the psychometric properties of the English version of the Self-Stigma Scale-Short (SSS-S), a nine-item self-report self-stigma measurement, among U.S. adults with psychiatric disabilities. METHOD: We obtained reliability and validity evidence from a sample of 275 adults with psychiatric disabilities. RESULTS: Exploratory factor analysis (EFA; n = 139) yielded a two-factor solution that accounts for 64.97% of the variance. Confirmatory factor analysis (CFA; n = 136) was conducted to compare alternative solutions, including a single-factor model, a two-correlated-factor model, a three-correlated-factor model, and a bifactorial model. The CFA results supported the bifactor S·I - 1 model as a superior latent factor structure for the SSS-S. The coefficient ω of the SSS-S was .94, indicating excellent internal reliability. Concurrent validity of the SSS-S was supported by significant positive correlations with societal stigma and psychiatric symptom severity, and negative correlations with psychiatric disability acceptance, general self-efficacy, and hope. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The overall findings concluded that the English version of the SSS-S demonstrated reliable and valid scores and a primarily unidimensional structure of self-stigma among U.S. adults with psychiatric disabilities. Given the adverse impact of self-stigma and its relationships with recovery-related constructs shown in this study, the routine use of the SSS-S is recommended in psychiatric rehabilitation settings.

Quality control of psychoactive substances in human breastmilk samples from a human milk bank by disposable pipette extraction-gas chromatography-mass spectrometry.

The lack of data regarding infant exposure to drugs of abuse consumed by lactating mothers has become a major health concern. Investigating psychoactive substances and their metabolites in breastmilk is an analytical approach to estimate the rate at which drugs of abuse are excreted and how much infants are exposed to them. In this study, we have developed and validated a GC-MS method using disposable pipette tips for simultaneously extracting ten analytes from breastmilk samples obtained from a milk bank in the city of Ribeirão Preto, Brazil. All the 67 analyzed samples tested negative for all the analytes. This is the first study that has applied disposable pipette extraction to analyze drugs of abuse in breastmilk samples.

Breastfeeding, the most effective single strategy to reduce child mortality, provides numerous benefits for both the mother and the infant. The mother's consumption habits during breastfeeding strongly influence breastmilk quality and the newborn's nutrition. Given that drugs of abuse negatively affect both the mother's and the infant's health, analyzing breastmilk samples helps to estimate infant exposure to these drugs and to evaluate how severe this public health issue is. We have developed a new method to monitor ten substances in breastmilk, to improve our understanding of this issue in Brazil. None of the substances were detected in the few samples obtained from a milk bank, which showed that this organization successfully analyzes the donor's profile and conducts effective anamnesis. Future analysis of a larger number of samples and hence more data could help to describe the current scenario in more detail.

A Simulated Patient Protocol for Implementing Evidence-Based Practices in Health Care Delivery.

Background: Substantial work has been done to update or create evidence-based practices (EBPs) in the changing health care landscape. However, the success of these EBPs is limited by low levels of clinician implementation. The goal of this study is to describe the use of simulated patient (SP) methodology as a framework to develop implementation bundles to increase the effectiveness, sustainability, and reproducibility of EBPs across health care clinicians. The primary outcome was identifying likely facilitators for the successful implementation of EBP. Our secondary outcome was the assess the feasibility of using SPs to illuminate likely implementation barriers and facilitators. Methods: We observed 12 primary care clinicians' first-time experiences with six unique decision-making algorithms for use with patients exhibiting concerning behaviors associated with long-term opioid therapy (LTOT) for chronic pain over Zoom. Each clinician was paired with two simulated patients trained to portray individuals with one of the concerning behaviors addressed by the algorithms. The Standardized Patient-evaluations were followed by CFIR guided one-on-one interviews with the clinicians. Results: The SP portrayal illuminated factors that were pertinent to address in the implementation bundle. SPs were realistic in their portrayal of patients with concerning behaviors associated with LTOT for chronic pain, but clinicians also noted that their patients in practice may have been more aggressive about their treatment plan. Conclusions: SP simulation provides unique opportunities for obtaining crucial feedback to identify best practices in the adoption of new EBPs for high-risk patients.

Identifying patients at increased risk of non-ventilator-associated pneumonia on admission to hospital: a pragmatic prognostic screening tool to trigger preventative action.

BACKGROUND: Non-ventilator healthcare-associated pneumonia (NV-HAP) is an important healthcare-associated infection. This study tested the feasibility of using routine admission data to identify those patients at high risk of NV-HAP who could benefit from targeted, preventive interventions. METHODS: Patients aged ≥64 years who developed NV-HAP five days or more after admission to elderly-care wards, were identified by retrospective case note review together with matched controls. Data on potential predictors of NV-HAP were captured from admission records. Multi-variate analysis was used to build a prognostic screening tool (PRHAPs); acceptability and feasibility of the tool was evaluated. RESULTS: A total of 382 cases/381 control patients were included in the analysis. Ten predictors were included in the final model; nine increased the risk of NV-HAP (OR between 1.68 and 2.42) and one (independent mobility) was protective (OR 0.48; 95% CI 0.30-0.75). The model correctly predicted 68% of the patients with and without NV-HAP; sensitivity 77%; specificity 61%. The PRHAPs tool risk score was 60% or more if two predictors were present and over 70% if three were present. An expert consensus group supported incorporating the PRHAPs tool into electronic logic systems as an efficient mechanism to identify patients at risk of NV-HAP and target preventative strategies. CONCLUSIONS: This prognostic screening (PRHAPs) tool, applied to data routinely collected when a patient is admitted to hospital, could enable staff to identify patients at greatest risk of NV-HAP, target scarce resources in implementing a prevention care bundle, and reduce the use of antimicrobial agents.
