In this article, we report on qualitative findings pertaining to low-income people's perceptions of and responses to 'poverty stigma,' a key component of social exclusion with important implications for health and well-being. Our findings are drawn from a multimethod study designed to investigate experiences of social exclusion and social isolation among people living on low incomes. We conducted semistructured individual interviews (n = 59) and group interviews (total n = 34) with low-income residents of two large Canadian cities. Data were analyzed using thematic content analysis techniques. Participants overwhelmingly thought that other members of society tend to view them as a burden to society-as lazy, disregarding of opportunities, irresponsible, and opting for an easy life. Low-income people responded to perceived stigma with a variety of cognitive and behavioral strategies that reflected their efforts to reconcile their perceived 'social' and 'personal' identities. These strategies included confronting discrimination directly, disregarding responses from others, helping other low-income people, withdrawing and isolating themselves from others, engaging in processes of cognitive distancing, and concealing their financial situation.

Neo- and perinatal mortality is high in most of Africa. Twins are at particular risk of perinatal mortality. The contribution of traditional remedies is seldom addressed. The case histories of two sets of twins who were treated with traditional remedies are described. The herbal remedies were analysed using gas chromatography-mass spectrometry. In one family, both siblings survived, albeit with hepatic damage. In the other family, one twin died within 24 h and the second one month after admission with a diagnosis of veno-occlusive liver disease (VOD). In both cases, the presence of the toxic pyrrolizidine alkaloid retrorsine, which is known to lead to VOD, was identified. Health-care workers should be aware of the possibility of traditional medicine administration as a cause of illness, specifically in twin births. [ABSTRACT FROM AUTHOR]

Adolescent mothers are prone to live in poor conditions, lack adequate financial resources, suffer high stress, encounter family instability, and have limited educational opportunities. These factors contribute to inadequate parent-child interactions and diminished infant development. Social support can promote successful adaptation for adolescent mothers and their children. This review article describes the support needs and challenges faced by adolescent parents and their children, the support resources available to and accessed by adolescent parents, and existing support-education intervention studies, to provide directions for future research. Relevant research published between January 1982 and February 2003 was obtained from online database indices and retrieved article bibliographies. Frequently encountered problems included small sample sizes and attrition, lack of suitable comparison groups, and measurement inconsistencies. When planning support-education interventions, content, duration, intensity, mode, level, intervention agents, and targets should be considered. Future research can address these challenges.

The purpose of this ethnographic study was to understand how immigrant women caregivers accessed support from community resources and identify the barriers to this support. The study included 29 Chinese and South Asian women caring for an ill or disabled child or adult relative. All experienced barriers to accessing community services. Some possessed personal resources and strategies to overcome them; others remained isolated and unconnected. Family and friends facilitated connections, and a connection with one community service was often linked to several resources. Caregivers who failed to establish essential ties could not initiate access to resources, and community services lacked outreach mechanisms to identify them. These findings contribute new understanding of how immigrant women caregivers connect with community resources and confirm the impact of immigration on social networks and access to support.

The recruitment of articulate, expressive participants is an essential part of methodology in qualitative research. This article presents the authors' experience in the recruitment of immigrant women of Chinese and South Asian origin in an ethnographic study. The study included women caring for an adult or child family member who had a chronic health problem. Knowledge of women family caregivers' health is restricted by the failure to include diverse groups of women in research. In this article, the authors discuss issues related to recruitment and participation of immigrant women in research, including establishing access to diverse groups of women, benefits for immigrant women, and placing the researcher and research process on the same level. Practical research strategies to address these issues and engage the women in research that portrays their perspectives are presented. The authors' discussion concludes with reflection on their experience and that of other researchers. [ABSTRACT FROM AUTHOR]

This paper describes sources and types of support, appraisal of support, and use of social support as a strategy for coping with Acquired Immune Deficiency Syndrome (AIDS)-related stresses. Thirty people with haemophilia, 23 family caregivers and 17 bereaved relatives participated. The study was conducted in two stages: individual interviews and mailed questionnaires. The key coping strategies used were 'normalizing personal relationships' and 'seeking informational support'. Informational support was provided by health professionals and practical aid by relatives. Respondents reported insensitivity, prejudice and avoidance from others. Participants needed peers for emotional and affirmational support, and professionals for informational support. The preferred intervention was support groups, co-led by professionals and peers.

1 The value of a portable breathlyser (Alcometer AE-M2) in the assessment of gastric emptying after alcohol ingestion was investigated by comparing breath and venous blood alcohol concentrations with simultaneous scintigraphic measurements of gastric emptying rate. 2 Alcohol absorption, as determined by the area under the venous blood alcohol concentration-time curve during the first 30 min, correlated with gastric emptying during the same period, implying dependence of the rate of alcohol absorption on gastric emptying rate. 3 There was no correlation between breath and venous alcohol concentrations during the first 15 min after alcohol ingestion, but a significant correlation was observed thereafter. 4 Breath alcohol measurements may be sufficient to detect gross alterations in gastric emptying but measurements of venous blood alcohol are likely to be more reliable.

PURPOSE: To evaluate the predictive value of N-terminal pro B-type natiuretic peptide (NT-proBNP) reference cut-off values as diagnostic markers for left ventricular systolic dysfunction (LVSD). STUDY DESIGN: A retrospective study assessing the use of NT-proBNP in the diagnostic algorithm for the investigation of patients with suspected signs and symptoms of LVSD presenting to primary care. RESULTS: A generic NT-proBNP cut-off (150 ng/l) value has similar negative and positive predictive valves, specificity and sensitivity compared to age and sex specific cut-off values. CONCLUSION: When using NT-proBNP as a triage tool for screening patients with signs and symptoms suggestive of LVSD, a simple generic cut-off level is as effective as more complex age sex specific cut-off values.

OBJECTIVE: Although nasal continuous positive airway pressure is widely used in neonatal units, its use in neonatal transport is not yet established. Previous reports have been limited to small numbers of primary road transports and larger numbers of return transports while its use in air transportation has not been reported. The aim of this study was to assess the safety and effectiveness of transporting neonates and infants by road or air while treated with nasal continuous positive airway pressure. METHODS: We conducted a retrospective review of the records of all infants transported between January 1, 2004, and November 1, 2005. RESULTS: A total of 220 infants were treated with nasal continuous positive airway pressure; of these, 13 infants (6%) were intubated before transport, leaving 207 infants transported on a median nasal continuous positive airway pressure of 7 cm H(2)O. Thirty infants were transported by fixed or rotary wing aircraft and 190 by road. No infants required intubation or bag and mask ventilation during transport. Twenty-eight infants (13%) required intubation within 24 hours of arrival at the receiving hospital, 4 infants (2%) were intubated > 24 hours after arrival, 11 infants (5%) were intubated for surgery, and 164 infants (73%) were never intubated. A total of 111 infants (50%) were preterm and < 72 hours old at transport, and 32 infants (15%) were < or = 32 weeks' gestational age and < 72 hours old at transport. Fraction of inspired oxygen was significantly lower at the end of transport (0.45 vs 0.34). CONCLUSIONS: Nasal continuous positive airway pressure is effective and has an acceptable safety margin for the road-based transportation of infants with acute respiratory distress. Air transport is feasible but larger studies are required to assess safety. [ABSTRACT FROM AUTHOR]

Background: Care for infants born at 22-24 weeks' gestation varies globally, with an increasing willingness to provide survival-focused ('active') care for infants born at 22 weeks' gestation in recent years. This study aims to report changes in care for infants born at 22-24 weeks before and after the introduction of a statewide guideline for extreme prematurity (EP)., Methods: A retrospective cohort study was conducted, including all live births at 22-24 weeks in tertiary perinatal centres from 1 January 2015 to 31 December 2022 in Victoria, Australia. Medical records were reviewed to obtain antenatal history and perinatal outcomes. Data on in utero referral and transfer to tertiary perinatal centres were sourced from the statewide perinatal emergency retrieval service (Paediatric Infant Perinatal Emergency Retrieval, PIPER) database. Changes in PIPER referrals and transfers, survival-focused care and survival at 28 days preguideline and postguideline were assessed using logistic regression., Results: Following the guideline, at 22 weeks' gestation, there was an increase in referrals to PIPER and a 3.31 (95% CI 1.84 to 5.95) higher likelihood of in utero transfer to tertiary centres.Following the guideline, infants had a 6.67 (95% CI 1.40 to 31.72) higher likelihood of receiving survival-focused care at 22 weeks, and a 5.57 (95% CI 1.22 to 25.44) higher likelihood at 23 weeks. All 24-week live births received survival-focused care at birth. The 28-day survival for infants who received survival-focused care was unchanged preguideline and postguideline., Conclusion: Following the publication of the EP guideline in Victoria, in utero referrals and transfers at 22 weeks' gestation have increased, as has survival-focused management of inborn live births at 22-24 weeks., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Aim: This study aims to compare trainee-modified report percentage rate and trainee/consultant satisfaction regarding the feedback process before and after implementation of an automated report comparison tool., Materials and Methods: An automated report comparison tool utilising natural language processing, presenting the trainee's preliminary report beside the final consultant report with changes highlighted, was used in a prospective interventional study. Modification rates, including character counts, of co-authored computed tomography (CT) studies were recorded before and after tool implementation over two 6-month periods and compared with Student's t-test. Trainees and consultants were surveyed before and after the interventional period for time spent and feedback satisfaction., Results: In total, 3851 (81.7%) of 4175 reports were modified in the baseline preimplementation phase, and 5215 (69.6%) of 7489 reports were modified during the postimplementation phase (p < .001). The average character count change preimplementation was 132, corresponding to 9.0% of the original preliminary report, compared with 91 characters and 7.1% postimplementation, respectively (p < .001). This statistically significant difference generally applied regardless of the level of trainee experience. Prospective data collected in the preimplementation period revealed that for more than two-thirds of after-hours shifts, trainees spent fewer than 5 minutes receiving feedback on their after-hours work. At the conclusion of the implementation phase, 92.3% of trainees and 70% of consultants agreed that the report comparison tool improved feedback., Conclusion: Following the implementation of an automated report comparison tool, there was a reduction in trainee report modification rates and subjectively improved trainee feedback. This adjunct to existing feedback mechanisms presents a relatively simple intervention to facilitate efficient case review and feedback., (Crown Copyright © 2024. Published by Elsevier Ltd.

Background: Many clinicians overestimate mortality and disability rates in infants born extremely preterm. We developed a digital tool ('NIC-PREDICT') that predicts infant mortality and survival with and without major disability in infants born 23-27 weeks' gestation., Aims: To determine if clinicians could use NIC-PREDICT accurately, and if their perceptions of infant outcomes improved after its release in 2021., Materials and Methods: Midwives, nurses, obstetricians, neonatologists and paediatricians working in tertiary and non-tertiary hospitals in Victoria were asked to use NIC-PREDICT to estimate three mutually exclusive outcomes: (i) mortality; (ii) survival free of major disability; and (iii) survival with major disability for six different scenarios where a liveborn infant was offered survival-focused care after birth. The proportions who completed the survey (responded to all six scenarios) and the proportions able to provide 100% accurate results for all scenarios were determined. Estimates of the three outcomes were compared with true rates., Results: A total of 85 clinicians responded: 70 (82%) completed the survey, with an overall accuracy of 76%. Overall, predictions of mortality were accurate (mean difference from true value 0.7% (95% confidence interval (CI) -0.7, 2.1) P = 0.33), as were predictions of survival without major disability (mean difference - 0.7 (95% CI -3.0, 1.7) P = 0.58). However, survival with major disability was overestimated by 4.9% ((95% CI 1.7, 8.0) P = 0.003)., Conclusions: Most perinatal clinicians who responded used NIC-PREDICT correctly to estimate expected outcomes in infants born extremely preterm who are offered intensive care. Undue pessimism about survival with major disability remains an ongoing concern., (© 2024 The Authors.

It is recognized as a promising therapeutic strategy for cocaine use disorder to develop an efficient enzyme which can rapidly convert cocaine to physiologically inactive metabolites. We have designed and discovered a series of highly efficient cocaine hydrolases, including CocH5-Fc(M6) which is the currently known as the most efficient cocaine hydrolase with both the highest catalytic activity against (-)-cocaine and the longest biological half-life in rats. In the present study, we characterized the time courses of protein appearance, pH, structural integrity, and catalytic activity against cocaine in vitro and in vivo of a CocH5-Fc(M6) bulk drug substance produced in a bioreactor for its in vitro and in vivo stability after long-time storage under various temperatures (- 80, - 20, 4, 25, or 37 °C). Specifically, all the tested properties of the CocH5-Fc(M6) protein did not significantly change after the protein was stored at any of four temperatures including - 80, - 20, 4, and 25 °C for ~ 18 months. In comparison, at 37 °C, the protein was less stable, with a half-life of ~ 82 days for cocaine hydrolysis activity. Additionally, the in vivo studies further confirmed the linear elimination PK profile of CocH5-Fc(M6) with an elimination half-life of ~ 9 days. All the in vitro and in vivo data on the efficacy and stability of CocH5-Fc(M6) have consistently demonstrated that CocH5-Fc(M6) has the desired in vitro and in vivo stability as a promising therapeutic candidate for treatment of cocaine use disorder., (© 2024.

Abdominal aortic aneurysm (AAA) is a deadly, permanent ballooning of the aortic artery. Pharmacological and genetic studies have pointed to multiple proteins, including microsomal prostaglandin E 2 synthase-1 (mPGES-1), as potentially promising targets. However, it remains unknown whether administration of an mPGES-1 inhibitor can effectively attenuate AAA progression in animal models. There are still no FDA-approved pharmacological treatments for AAA. Current research stresses the importance of both anti-inflammatory drug targets and rigor of translatability. Notably, mPGES-1 is an inducible enzyme responsible for overproduction of prostaglandin E 2 (PGE 2 )-a well-known principal pro-inflammatory prostanoid. Here we demonstrate for the first time that a highly selective mPGES-1 inhibitor (UK4b) can completely block further growth of AAA in the ApoE-/- angiotensin (Ang)II mouse model. Our findings show promise for the use of a mPGES-1 inhibitor like UK4b as interventional treatment of AAA and its potential translation into the clinical setting., (© 2024. The Author(s).)

Effective sampling for severe acute respiratory syndrome 2 (SARS-CoV-2) is a common approach for monitoring disinfection efficacy and effective environmental surveillance. This study evaluated sampling efficiency and limits of detection (LODs) of macrofoam swab and sponge stick sampling methods for recovering infectious SARS-CoV-2 and viral RNA (vRNA) from surfaces. Macrofoam swab and sponge stick methods were evaluated for collection of SARS-CoV-2 suspended in a soil load from 6-in 2 coupons composed of four materials: stainless steel (SS), acrylonitrile butadiene styrene (ABS) plastic, bus seat fabric, and Formica. Recovery of infectious SARS-CoV-2 was more efficient than vRNA recovery on all materials except Formica (macrofoam swab sampling) and ABS (sponge stick sampling). Macrofoam swab sampling recovered significantly more vRNA from Formica than ABS and SS, and sponge stick sampling recovered significantly more vRNA from ABS than Formica and SS, suggesting that material and sampling method choice can affect surveillance results. Time since initial contamination significantly affected infectious virus recovery from all materials, with vRNA recovery showing limited to no difference, suggesting that SARS-CoV-2 vRNA can remain detectable after viral infectivity has dissipated. This study showed that a complex relationship exists between sampling method, material, time from contamination to sampling, and recovery of SARS-CoV-2. In conclusion, data show that careful consideration be used when selecting surface types for sampling and interpreting SARS-CoV-2 vRNA recovery with respect to presence of infectious virus.

Efficacy of cleaning methods against SARS-CoV-2 suspended in either 5% soil load (SARS-soil) or simulated saliva (SARS-SS) was evaluated immediately (hydrated virus, T0) or 2 hours post-contamination (dried virus, T2). Hard water dampened wiping (DW) of surfaces, resulted in 1.77-3.91 log reduction (T0) or 0.93-2.41 log reduction (T2). Incorporating surface pre-wetting by spraying with a detergent solution (D + DW) or hard water (W + DW) just prior to dampened wiping did not unilaterally increase efficacy against infectious SARS-CoV-2, however, the effect was nuanced with respect to surface, viral matrix, and time. Cleaning efficacy on porous surfaces (seat fabric, SF) was low. W + DW on stainless steel (SS) was as effective as D + DW for all conditions except SARS-soil at T2 on SS. DW was the only method that consistently resulted in > 3-log reduction of hydrated (T0) SARS-CoV-2 on SS and ABS plastic. These results suggest that wiping with a hard water dampened wipe can reduce infectious virus on hard non-porous surfaces. Pre-wetting surfaces with surfactants did not significantly increase efficacy for the conditions tested. Surface material, presence or absence of pre-wetting, and time post-contamination affect efficacy of cleaning methods., (Published by Oxford University Press on behalf of Applied Microbiology International 2023.)

Objective: To determine if risk-adjusted survival of patients with CDH has improved over the last 25 years within centers that are long-term, consistent participants in the CDH Study Group (CDHSG)., Summary Background Data: The CDHSG is a multicenter collaboration focused on evaluation of infants with CDH. Despite advances in pediatric surgical and intensive care, CDH mortality has appeared to plateau. Herein, we studied CDH mortality rates amongst long-term contributors to the CDHSG., Methods: We divided registry data into 5-year intervals, with Era 1 (E1) beginning in 1995, and analyzed multiple variables (operative strategy, defect size, and mortality) to assess evolution of disease characteristics and severity over time. For mortality analyses, patients were risk stratified using a validated prediction score based on 5-minute Apgar (Apgar5) and birth weight. A risk-adjusted, observed to expected (O:E) mortality model was created using E1 as a reference., Results: 5203 patients from 23 centers with >22years of participation were included. Birth weight, Apgar5, diaphragmatic agenesis, and repair rate were unchanged over time (all P > 0.05). In E5 compared to E1, minimally invasive and patch repair were more prevalent, and timing of diaphragmatic repair was later (all P < 0.01). Overall mortality decreased over time: E1 (30.7%), E2 (30.3%), E3 (28.7%), E4 (26.0%), E5 (25.8%) ( P = 0.03). Risk-adjusted mortality showed a significant improvement in E5 compared to E1 (OR 0.78, 95% CI 0.62-0.98; P = 0.03). O:E mortality improved over time, with the greatest improvement in E5., Conclusions: Risk-adjusted and observed-to-expected CDH mortality have improved over time., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.
