Abstract
ISSUE ADDRESSED Human-centred design thinking (HCDT) is gaining traction to develop appropriate public health interventions. The HCDT process helps frame problems with intention and encourages experimentation through collaboration. Public health graduates need an expanded toolkit to solve both the complex known problems of today, and the adaptability to solve the unknown problems of tomorrow. But how is the health promotion workforce being prepared with this innovation capability? This scoping review aims to provide a pedagogical understanding of teaching HCDT in public health education. METHODS The Arksey & O'Malley framework is used to structure this review. Peer-reviewed articles written from 2000 to 2023 across eight databases were analysed. The data extracted included: author/year, setting, aim/purpose, participants, HCDT framework, HCDT methods, outcomes and challenges. RESULTS Nine relevant publications were included from a total of 208 records. The first reported use of HCDT in public health and health promotion teaching was in 2015. Teaching inspiration drew from established HCDT frameworks: d.school and IDEO which promote the iterative process of empathy/inspiration, ideation and testing/implementation. CONCLUSIONS HCDT has been used for both designing public health curricula and for teaching students to apply it in their practice. First, HCDT methods can be used to problem-solve teaching and learning issues such as creating inviting learning environments and designing an HCDT unit. Second, the teaching of HCDT can prepare and equip the public health workforce to solve problems requiring tailored solutions from an empathetic and iterative stance working as a team. The teaching and practice of HCDT exemplifies the process of social innovation in health promotion. SO WHAT?: As an emerging field, future studies and applications should include clarifying and evaluating the HCDT stages used. More publications will enable a fuller understanding and potentially advocate the necessity of teaching and learning HCDT in public health and health promotion.

Abstract
Fetal tachyarrhythmia and aortic stenosis (AS) both disrupt fetal hemodynamics, leading to congestive heart failure, hydrops, and intrauterine demise. Traditional transplacental treatments for fetal supraventricular tachycardia (SVT) include digoxin, flecainide, and sotalol. However, the treatment of fetal SVT in the setting of AS has not been described, particularly in cases of refractory SVT. We present a case of a 27-year-old nulliparous female carrying a fetus with fetal AS diagnosed at 25 weeks of gestational age (GA). The patient was not a candidate for in utero valvuloplasty. During ultrasound monitoring at 32 and 6/7 weeks of gestation, fetal SVT with a heart rate of 230-260 beats per minute (bpm) was diagnosed. Maternal digoxin was initiated, and sotalol was subsequently added. Due to persistent fetal SVT and a worsening cardiac function, the patient was treated with direct adenosine administration via cordocentesis successfully terminating the fetal arrhythmia. Despite continued transplacental treatment with digoxin and sotalol throughout the course of pregnancy, the fetal SVT recurred at 35 and 5/7 weeks of gestation prompting delivery. Our case illustrates the use of direct intrauterine adenosine as a novel treatment for refractory fetal SVT in the setting of congenital aortic stenosis and concern about progression to fetal hydrops and fetal demise.

Abstract
OBJECTIVE This study provides a series of updated, evidence-based recommendations for the management of acute stroke. We aim to lay a foundation for the development of individual centres' internal protocols, serving as a reference for nursing care. METHODS We review the available evidence on acute stroke care. The most recent national and international guidelines were consulted. Levels of evidence and degrees of recommendation are based on the Oxford Centre for Evidence-Based Medicine classification. RESULTS The study describes prehospital acute stroke care, the operation of the code stroke protocol, care provided by the stroke team upon the patient's arrival at hospital, reperfusion treatments and their limitations, admission to the stroke unit, nursing care in the stroke unit, and discharge from hospital. CONCLUSIONS These guidelines provide general, evidence-based recommendations to guide professionals who care for patients with acute stroke. However, limited data are available on some aspects, showing the need for continued research on acute stroke management.

Abstract
The omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are precursors to immune regulatory and specialized pro-resolving mediators (SPM) of inflammation termed resolvins, maresins, and protectins. Evidence for lipid mediator formation in vivo can be gained through evaluation of their 5-lipoxygenase (LOX) and 15-LOX metabolic pathway precursors and downstream metabolites. We performed a secondary blood sample analysis from 60 participants in the Mothers, Omega-3, and Mental Health study to determine whether SPM and SPM precursors are augmented by dietary EPA- and DHA-rich fish oil supplementation compared to soy oil placebo. We also aimed to study whether SPM and their precursors differ in early and late pregnancy or between maternal and umbilical cord blood. We found that compared to placebo supplementation, EPA- and DHA-rich fish oil supplementation increased SPM precursor 17-hydroxy docosahexaenoic acid (17-HDHA) concentrations in maternal and umbilical cord blood (P = 0.02). We found that the D-series resolvin pathway marker 17-HDHA increased significantly between enrollment and late pregnancy (P = 0.049). Levels of both 14-HDHA, a maresin pathway marker, and 17-HDHA were significantly greater in umbilical cord blood than in maternal blood (P < 0.001, both).

Abstract
BACKGROUND Long-term follow-up was completed in 84 mother-infant pairs of 118 women who completed a randomized controlled trial of prenatal supplementation with EPA- or DHA-rich fish oil or soy oil placebo. The goal of this study was to determine whether prenatal omega-3 fatty acid supplementation protects offspring against development of early childhood allergies. METHODS AND FINDINGS Assessment of childhood allergic/atopic disease among offspring at age 36 months was performed by maternal interview using the National Health Interview Survey (NHIS) questions for childhood digestive allergies, wheezing, eczema or skin allergy, and respiratory allergy. Multiple logistic regressions examined the association between prenatal supplementation and childhood outcomes, adjusted for covariates. Eczema was reported in 26/84 (31%) of offspring at age 36 months, and was significantly more prevalent in the omega-3 supplementation groups vs. placebo: EPA 13/31 (41.9%); DHA 10/26 (38.5%); placebo 3/27 (11.1%), p=0.019. Compared to placebo, EPA and DHA were associated with ≥5 times risk of offspring eczema [odds ratios (ORs): EPA 5.8 (95% CI 1.4-23.3); DHA 5.0 (95% CI 1.2-21.0)]. After adjusting for other potential risk factors (race, birth weight, vaginal/Cesarean delivery, and maternal eczema) the magnitudes of association for omega-3 supplementation increased: EPA OR 8.1 (95% CI 1.4-45.6); DHA OR 9.6 (95% CI 1.6-58.5). Maternal eczema was also significantly associated with offspring eczema in the adjusted model: OR 10.8 (95% CI 2.1-54.3). CONCLUSION Contrary to our hypothesis, acids supplementation compared to soy oil was associated with a substantial increase in risk of childhood eczema. This association was not observed on childhood respiratory or digestive outcomes. It is unclear if these findings were driven by unfavorable effects of omega-3s, or whether there may have been unanticipated protective effects of the soy-based placebo with regards to eczema.

Abstract
The need for acidification in the Fenton and photo-Fenton process is often outlined as one of its major drawbacks, thus in this work the acidification of the Metoprolol (MET) is avoided by the addition of resorcinol (RES), which is used to simulate model organic matter. The experiments were carried out at natural pH (6.2) with different Fe(2+) (1, 2.5, 5, and 10 mg/L) and H2O2 (25, 50, 125 and 150 mg/L) concentrations. The performance of MET and RES degradation was assessed along the reaction time. Working with the highest concentrations (5 and 10 mg/L of ferrous iron and 125 and 150 mg/L of H2O2) more than 90% of MET and RES removals were reached within 50 and 20 min of treatment, respectively, by Fenton process. However a low mineralization was achieved in both cases, likely, due to by-products accumulation. Regarding to photo-Fenton process, within 3 min with the highest iron and hydrogen peroxide concentrations, a complete MET degradation was obtained and 95% of RES conversion was achieved. Parameters such Total Organic Carbon, Chemical Oxygen Demand, and AOS were measured. Intermediates were identified and MET degradation path was proposed in the presence of resorcinol. Finally, a comparison between Fenton and photo-Fenton processes at acid pH and at initial circumneutral pH was discussed. The positive effect of RES on Fenton and photo-Fenton systems has been confirmed, allowing the work at circumneutral pH.

Abstract
OBJECTIVES Large cohort studies have shown a high rate of first-line combination antiretroviral therapy (cART) regimen discontinuation in HIV-infected patients, attributed to characteristics of the cART regimen or toxicity. METHODS A cohort study of 274 patients receiving a first-line regimen was carried out. Patients' perceptions and beliefs prior to initiation were assessed using an attitude towards medication scale (0-15 points), and their satisfaction during therapy was assessed using an HIV treatment satisfaction questionnaire (HIVTSQ). Treatment discontinuation was defined as any switch in the cART regimen. RESULTS During 474.8 person-years of follow-up, 63 (23%) patients changed their cART regimen, mainly because of toxicity/intolerance (42; 67%). The overall rate of change was 13.2 per 100 patient-years [95% confidence interval (CI) 11.1-16.4 per 100 patient-years]. An efavirenz (EFV)-based single tablet regimen showed the highest rate of adverse events (27%), but the lowest rate of change (16%; 7.44 per 100 patient-years). Cox regression revealed a decreased hazard of first regimen termination with better initial attitude towards drugs [hazard ratio (HR) 0.76; 95% CI 0.62-0.93; P < 0.01] and higher satisfaction (HR 0.94; 95% CI 0.89-0.99; P = 0.01), and an increased hazard of termination with the presence of adverse events (HR 7.7; 95% CI 2.4-11.6; P < 0.01). One-third of patients (18 of 59; 31%) with mild/moderate adverse events (which were mainly central nervous system symptoms) continued the regimen; these patients, compared with those discontinuing therapy, showed better perception of therapy (mean score 14.4 versus 12.1, respectively; P = 0.05) and greater satisfaction during therapy (mean score 50.6 versus 44.6, respectively; P = 0.04). CONCLUSIONS Patients' beliefs and satisfaction with therapy influence the durability of the first antiretroviral regimen. These patient-related factors modulate the impact of mild adverse events, and could explain differences in the rate of discontinuation.

Abstract
We report on normal contact and friction measurements of model multicontact interfaces formed between smooth surfaces and substrates textured with a statistical distribution of spherical micro-asperities. Contacts are either formed between a rigid textured lens and a smooth rubber, or a flat textured rubber and a smooth rigid lens. Measurements of the real area of contact A versus normal load P are performed by imaging the light transmitted at the microcontacts. For both interfaces, A(P) is found to be sub-linear with a power law behavior. Comparison with two multi-asperity contact models, which extend the Greenwood-Williamson (J. Greenwood and J. Williamson, Proc. Royal Soc. London Ser. A, 295, 300 (1966)) model by taking into account the elastic interaction between asperities at different length scales, is performed, and allows their validation for the first time. We find that long range elastic interactions arising from the curvature of the nominal surfaces are the main source of the non-linearity of A(P). At a shorter range, and except for very low pressures, the pressure dependence of both density and area of microcontacts remains well described by Greenwood-Williamson's model, which neglects any interaction between asperities. In addition, in steady sliding, friction measurements reveal that the mean shear stress at the scale of the asperities is systematically larger than that found for a macroscopic contact between a smooth lens and a rubber. This suggests that frictional stresses measured at macroscopic length scales may not be simply transposed to microscopic multicontact interfaces.

Abstract
In this work, a simple route for the synthesis of surfactant-free immobilized palladium nanoparticles (Pd NPs) and their use as effective nanocatalysts for metal hydride decomposition is described. A mixture of ethanol : water was used as the reducing agent. Ethanol was added in a large excess to reduce the ionic Pd and stabilize the obtained Pd NPs. Ethanol is adsorbed on the surface of Pd allowing steric stabilization. Freshly prepared Pd NPs were immobilized onto quartz substrates modified with 3-mercaptopropyltrimethoxysilane. Pd interacts with the thiol group of the alkoxysilane that is adsorbed on the surface of NPs without the dissociation of the S-H bond. Different parameters affecting the synthesis of Pd NPs and their immobilization onto quartz substrates were evaluated. A comprehensive characterization of the synthesized Pd NPs was carried out by transmission electron microscopy (TEM), whereas total reflection X-ray fluorescence (TXRF) spectrometry was applied in order to evaluate their catalytic activity for solid-gas reactions. Immobilized Pd NPs were applied as nanocatalysts for the dissociative chemisorption of arsine at room temperature, yielding the formation of As-Pd bonds. Quartz substrates coated with nanosized Pd could be used as novel sensing platforms for total reflection X-ray fluorescence analysis. Arsenic can be detected in situ in natural water with a limit of detection of 0.08 μg L(-1).

Abstract
Physical activity (PA) is essential for good health. However, parents risk becoming less active because of the demands of parenting. This has consequences for children as parents are role models. The present study used a mixed-methods approach to explore parental self-regulation associated with PA. Data were collected from 36 parents with preschool-aged children. They were interviewed about their PA and their family's PA. Parents also completed PA and self-regulation questionnaires and wore an accelerometer for five days. Qualitative data were examined using an inductive approach to thematic analysis. It showed that parents felt that they had limited time for personal PA. Mothers' self-regulation was driven by an ethic of care and subjective norms, whereas fathers' self-regulation was driven by beliefs about the importance of autonomy. Nevertheless, both parents saw caring for their children as the main priority. Quantitative data were examined using multiple regression analyses. Results showed that different self-regulatory behaviours predicted the PA of mothers and fathers. Which predictors were significant depended on the type of activity and how it was measured. The findings warrant longitudinal research that would enable the effect of family dynamics on self-regulation associated with PA to be assessed.

Abstract
We report on the multicontact frictional dynamics of model elastomer surfaces rubbed against bare glass slides. The surfaces consist of layers patterned with thousands of spherical caps distributed both spatially and in height, regularly or randomly. Use of spherical asperities yields circular microcontacts whose radii are a direct measure of the contact pressure distribution. Optical tracking of individual contacts provides the in-plane deformations of the tangentially loaded interface, yielding the shear force distribution. We then investigate the stick-slip frictional dynamics of a regular hexagonal array. For all stick phases, slip precursors are evidenced and found to propagate quasistatically, normally to the isopressure contours. A simple quasistatic model relying on the existence of interfacial stress gradients is derived and predicts qualitatively the position of slip precursors.

Abstract
OBJECTIVE Azathioprine (AZA) is recognized among immunosuppressive medications as relatively safe during pregnancy for women with systemic lupus erythematosus (SLE) requiring aggressive treatment. This pilot study aimed to determine whether SLE therapy during pregnancy was associated with developmental delays in offspring. METHODS This cohort study included SLE patients with at least one live birth postdiagnosis. Medical histories were obtained via interviews and chart review. Multiple logistic regression was used to examine associations between SLE therapy during pregnancy and maternal report of special educational (SE) requirements (as proxy for developmental delays) among offspring. Propensity scoring (incorporating corticosteroid use, lupus flare, and lupus nephritis) was used to account for disease severity. RESULTS Of 60 eligible offspring from 38 mothers, 15 required SE services, the most common indication for which was speech delay. Seven (54%) of the 13 children with in utero AZA exposure utilized SE services versus 8 (17%) of 47 nonexposed children (P < 0.01). After adjustment for pregnancy duration, small for gestational age, propensity score, maternal education level, and antiphospholipid antibody syndrome, AZA was significantly associated with SE utilization occurring from age 2 years onward (odds ratio 6.6, 95% confidence interval 1.0-43.3), and bordered on significance for utilization at any age or age <2 years. CONCLUSION AZA exposure during SLE pregnancy was independently associated with increased SE utilization in offspring, after controlling for confounders. Further research is indicated to fully characterize developmental outcomes among offspring with in utero AZA exposure. Vigilance and early interventions for suspected developmental delays among exposed offspring may be warranted.

Abstract
OBJECTIVE The purpose of this study was to determine the pregnancy outcome of asymptomatic patients in the second trimester with a nonmeasurable cervical length (0 mm). STUDY DESIGN This retrospective cohort study included 78 patients with singleton pregnancies and a sonographic nonmeasurable cervix that was detected at 14-28 weeks of gestation. Patients with cervical cerclage were excluded. RESULTS We found that (1) 75.3% of the patients delivered before 32 weeks of gestation; (2) the median diagnosis-to-delivery interval was 20.5 days, and the delivery rate within 7 and 14 days was 28.2% and 35.6%, respectively; and (3) patients with a nonmeasurable cervix that was diagnosed at <24 weeks of gestation had a shorter median diagnosis-to-delivery interval than patients who were diagnosed at 24-28 weeks of gestation (17.5 vs 41 days; P = .009). CONCLUSION Asymptomatic women with a nonmeasurable cervix in the second trimester have a median diagnosis-to-delivery interval of approximately 3 weeks. Almost 65% of these patients will not deliver within 2 weeks, yet 75% of them will deliver before 32 weeks of gestation. The earlier a nonmeasurable cervix is identified, the shorter the diagnosis-to-delivery interval.

Abstract
OBJECTIVE The aim of this study was to determine whether the risk of early spontaneous preterm delivery (PTD) in asymptomatic women with a sonographic cervical length of ≤ 15 mm in the mid-trimester changes as a function of gestational age at diagnosis. METHODS This cohort study included 109 asymptomatic patients with a sonographic cervical length of ≤ 15 mm diagnosed at 14-24 weeks of gestation. Women with a multifetal gestation, cerclage and a cervical dilatation of > 2 cm were excluded. The study population was stratified by gestational age at diagnosis (< 20 weeks vs. 20-24 weeks) and by cervical length (≤ 10 mm vs. 11-15 mm). The primary outcome variables were PTD at < 28 and < 32 weeks of gestation and the diagnosis-to-delivery interval. RESULTS The median gestational age at diagnosis of a short cervix before 20 weeks and at 20-24 weeks was 18.9 and 22.7 weeks, respectively. Women diagnosed before 20 weeks had a higher rate of PTD at < 28 weeks (76.9% vs. 30.9%; P < 0.001) and at < 32 weeks (80.8% vs. 48.1%; P = 0.004), and a shorter median diagnosis-to-delivery interval (21 vs. 61.5 days, P = 0.003) than those diagnosed at 20-24 weeks. The rate of amniotic fluid sludge was higher among patients diagnosed with a short cervix at < 20 weeks of gestation than in those in whom it was diagnosed between 20 and 24 weeks (92.3% vs. 48.2%; P < 0.001). CONCLUSIONS Asymptomatic women with a sonographic cervical length of ≤ 15 mm diagnosed before 20 weeks of gestation have a dramatic and significantly higher risk of early preterm delivery than women diagnosed at 20-24 weeks. These findings can be helpful to physicians in counseling these patients, and may suggest different mechanisms of disease leading to a sonographic short cervix before or after 20 weeks of gestation.

Abstract
Granzymes are key components of the cytotoxic arm of the immune response, which play critical roles in eliminating host cells infected by intracellular pathogens and transformed cells. Although the induction of cell death is likely a central process underlying the function of these enzymes, little is known about whether granzymes use additional mechanisms to exert their antipathogen activity. This study identifies La, a phosphoprotein involved in multiple roles in cellular and viral RNA metabolism, as the first nonapoptotic substrate of granzyme H (gzmH), a cytotoxic granule protease that is constitutively expressed by NK cells. Cleavage of La by gzmH occurs at Phe-364 (P(1) site) and generates a COOH-terminal truncated form of La that loses nuclear localization and decreases HCV (hepatitis C virus)-internal ribosome entry site (IRES)-mediated translational activity. The ability of gzmH to cleave host proteins involved in essential viral functions provides a novel mechanism by which granzymes can mediate direct antiviral activities.

Abstract
In kidney recipients, the immunosuppressant sirolimus has been associated with a decreased incidence of de novo posttransplant malignancies (including prostate cancer). But the effect of sirolimus on the prostate-specific antigen (PSA) blood level, an important prostate cancer screening tool, remains unknown. We studied male kidney recipients >50 years old (transplanted from January 1994 to December 2006) without clinical evidence for prostate cancer. Pre- and posttransplant PSA levels were analyzed for 97 recipients (n = 19 on sirolimus, n = 78 on tacrolimus [control group]). Pretransplant PSA was similar for sirolimus versus tacrolimus recipients (mean, 1.8 versus 1.7 ng/mL, p = 0.89), but posttransplant PSA was significantly lower for recipients on sirolimus (mean, 0.9 versus 1.9 ng/mL, respectively, p < 0.001). The mean difference between pretransplant and posttransplant PSA was -0.9 ng/mL (50.0%, p = 0.006) for the sirolimus group versus +0.2 ng/mL (+11.8%, p = 0.24) for the tacrolimus group. By multivariate analysis, only pretransplant PSA and immunosuppression with sirolimus independently impacted posttransplant PSA. Our data strongly suggest that sirolimus is associated with a significant PSA decrease in kidney recipients. Future studies must investigate the clinical implications of our findings for the use of PSA for prostate cancer screening in male kidney recipients on sirolimus.

Abstract
A piece of paper coiled up in a tube hugs the wall in order to minimize its elastic energy. However, a moment's observation shows that the paper fails to make complete contact near its ends. Here, we show that the detached region in the inner part of the coil touches down the tube wall in an angle that is independent of the system size, thickness and stiffness of the surface. This angle is universal for any coiled sheet whose unstressed state is initially flat. Our results show how the shape and stress distribution for this detached region define the geometry and mechanical equilibrium for the rest of the sheet. In particular, we find scaling relations to describe the structure of the outer part of the coil, in contact with the tube wall, as a function of the number of times the sheet is coiled,

Abstract
Granzymes (granule enzymes) are proteases released from cytotoxic lymphocyte granules into target cells to protect mammals from virus infection and transformed cells. Once released into the cytoplasm of the target cell, granzymes activate specific pathways to induce cell death. Although the induction of target cell death has been considered the central function for these proteases, accumulating evidence suggests that granzymes also possess additional non-death-related functions. Thus, some granzymes can achieve direct antiviral activities through the cleavage of proteins encoded by viruses as well as host factors required for the viral life cycle. The presence of elevated concentrations of circulating granzymes in various inflammatory processes and granzyme-mediated cleavage of extracellular substrates suggest that these proteases may have extracellular effects relevant to virus and tumor rejection and the pathogenesis of chronic inflammatory diseases. Here, we discuss the current knowledge of the substrates and the proposed non-apoptotic functions of granzymes, with special interest in non-death-related functions of granzymes inside the target cell.

Abstract
Allelic frequencies of 15 short tandem repeats (STR) markers (CSF1PO, FGA, THO1, TPOX, VWA, D3S11358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, D19S433 and D2S1338) were determined using the AmpFl STR Identifiler PCR Amplification Kit in Puerto Rican American individuals (N=205) from Massachusetts. The FGA, D18S51 and D2S1338 loci had a high power of discrimination (PD) with values of 0.967, 0.965 and 0.961, respectively. Significant deviations from the Hardy-Weinberg (HW) equilibrium were not detected. An important genetic contribution of Caucasian European (76.4%) was detected in Puerto Rican Americans. However, comparative analysis between Puerto Rican American and other neighboring populations from United States mainly with African and Caucasian Americans, revealed significant differences in the distribution of STR markers. Our results are important for future comparative genetic studies of different American ethnic groups, in particular a cultural group called Hispanic-Americans and should be helpful for forensic and paternity testing.

Abstract
Broncholiths, which usually arise from calcified peribronchial lymph nodes, can be found by radiography or bronchoscopy. We describe the case of a 19-year-old man who had experienced lithoptysis of bronchial hydroxyapatite calculi for over 6 months and who reported having sandy expectoration since childhood. Exhaustive clinical, radiographic, and endoscopic diagnostic studies detected no calcified lesions in the thorax that could explain the origin of the broncholiths. Therefore, we propose that broncholiths may form by mechanisms similar to those involved in calculi formation in other locations.

Abstract
The postictal behavioral depression (PBD), characterized by behavioral immobility and unresponsiveness to environmental stimuli, observed after a stage 5 kindling seizure is opioid dependent. Morphine injection prolongs while naloxone and naltrexone (opioid antagonists) reduce or eliminate PBD. Opioids have clear rewarding actions that can be easily detected by place preference conditioning (PPC). In the present study, we evaluated if the opioid release after a stage 5 kindling seizure that produces PBD could induce PPC. Male rats were kindled in the medial preoptic area (MPOA), the amygdala (AMG) or insular cortex (IC). After kindling was established their initial preference in a three-compartment chamber was determined. During conditioning, subjects received a standard kindling stimuli that evoked a stage 5 seizure. At the end of the after discharge and during the PBD the animals were placed in the non-preferred chamber for 30 min. On alternate days they were placed without stimulation in the preferred chamber. At the end of conditioning the kindled groups showed a clear change of preference. This change of preference was completely blocked by injection of naloxone. These results suggest that opioid release after a stage 5 kindling seizure can induce a positive affect of sufficient intensity and duration to induce conditioning.
