Published: June 2024

ObjectivesWhen adverse events (AE) occur, there are different consequences for healthcare professionals. The environment in which professionals work can influence the experience. This study aims to explore the experiences of second victims (SV) among health professionals in Argentina.MethodsA phenomenological study was used with in-depth interviews with healthcare professionals. Audio recordings and verbatim transcriptions were analyzed independently for themes, subthemes, and codes.ResultsThree main themes emerged from the analysis: navigating the experience, the environment, and the turning point. Subthemes were identified for navigating the experience to describe the process: receiving the impact, transition, and taking action.ConclusionSVs undergo a process after an AE. The environment is part of this experience. It is a turning point in SVs’ professional and personal lives. Improving the psychological safety (PS) environment is essential for ensuring the safety of SVs.

The Genus Distribution of Cubic Graphs and Asymptotic Number of Rooted Cubic Maps with High Genus
Authors: Gao Zhicheng 
Published: June 2024

Let $C_{n,g}$ be the number of rooted cubic maps with $2n$ vertices on the orientable surface of genus $g$. We show that the sequence $(C_{n,g}:g\ge 0)$ is asymptotically normal with mean and variance asymptotic to $(1/2)(n-\ln n)$ and $(1/4)\ln n$, respectively. We derive an asymptotic expression for $C_{n,g}$ when $(n-2g)/\ln n$ lies in any closed subinterval of $(0,1)$.Using rotation systems and Bender's theorem about generating functions with fast-growing coefficients, we derive simple asymptotic expressions for the numbers of rooted regular maps, disregarding the genus. In particular, we show that the number of rooted cubic maps with $2n$ vertices, disregarding the genus, is asymptotic to $\frac{3}{\pi}\,n!6^n$.

Abstract
This paper presents three distinct wave trains that occurred on 2023 April 21: a broad quasiperiodic fast-propagating (QFP) wave train and bidirectional narrow QFP wave trains. The broad QFP wave train expands outward in a circular wave front, while bidirectional narrow QFP wave trains propagate in the northward and southward directions, respectively. The concurrent presence of the wave trains offers a remarkable opportunity to investigate their respective triggering mechanisms. Measurement shows that the speed of the broad QFP wave train is in the range of 300–1100 km s−1 in different propagating directions. There is a significant difference in the speed of the bidirectional narrow QFP wave trains: the southward propagation achieves 1400 km s−1, while the northward propagation only reaches about 550 km s−1 accompanied by a deceleration of about 1–2 km s−2. Using the wavelet analysis, we find that the periodicity of the propagating wave trains in the southward and northward directions closely matches the quasiperiodic pulsations exhibited by the flares. Based on these results, the narrow QFP wave trains were most likely excited by the intermittent energy release in the accompanying flare. In contrast, the broad QFP wave train had a tight relationship with the erupting filament, probably attributed to the unwinding motion of the erupting filament, or the leakage of the fast sausage wave train inside the filament body.

Abstract
We present JWST observations of the Crab Nebula, the iconic remnant of the historical SN 1054. The observations include NIRCam and MIRI imaging mosaics plus MIRI/MRS spectra that probe two select locations within the ejecta filaments. We derive a high-resolution map of dust emission and show that the grains are concentrated in the innermost, high-density filaments. These dense filaments coincide with multiple synchrotron bays around the periphery of the Crab's pulsar wind nebula (PWN). We measure synchrotron spectral index changes in small-scale features within the PWN’s torus region, including the well-known knot and wisp structures. The index variations are consistent with Doppler boosting of emission from particles with a broken power-law distribution, providing the first direct evidence that the curvature in the particle injection spectrum is tied to the acceleration mechanism at the termination shock. We detect multiple nickel and iron lines in the ejecta filaments and use photoionization models to derive nickel-to-iron abundance ratios that are a factor of 3–8 higher than the solar ratio. We also find that the previously reported order-of-magnitude higher Ni/Fe values from optical data are consistent with the lower values from JWST when we reanalyze the optical emission using updated atomic data and account for local extinction from dust. We discuss the implications of our results for understanding the nature of the explosion that produced the Crab Nebula and conclude that the observational properties are most consistent with a low-mass Fe core-collapse supernova, even though an electron-capture explosion cannot be ruled out.

Potential distribution of major plant units under climate change scenarios along an aridity gradient in Namibia
Authors: Naftal Leena , De Cauwer Vera , Strohbach Ben J. 
Published: June 2024

Objectives: Climate change is expected to have major impacts on plant species distribution worldwide. These changes can affect plant species in three ways: the timing of seasonal activities (phenology), physiology and distribution. This study aims to predict the effect of shifting climatic conditions on the major vegetation units along an aridity gradient through Namibia. Study area: Namibia’s vegetation is characterised by open woodland in the northeast to low open shrubland in the southern part of the country. These differences are a result of increasing aridity from north to south with a rainfall gradient from 100 mm to 600 mm. Namibia is projected to have an increase in annual mean temperature of 2°C by the end of the 21st century. Methods: A vegetation classification was done for 1,986 relevés using cluster analysis, a Multi-Response Permutation Procedure and indicator species analysis. The current distribution of the vegetation classes was modelled with Random Forest. Future projections for the most important climate variables were used to model the potential distribution of the vegetation units in 2080. This modelling approach used two scenarios of Representative Concentration Pathways (4.5 and 8.5) from two Global Climate Models – the IPSL–CM5A–LR and HAdGEM2–ES. Results: The predicted distribution shows a high expansion potential of Eragrostis rigidior­­-Peltophorum africanum mesic thornbush savannas, Combretum africanum-Terminalia sericea broad-leafed savannas and Senegalia mellifera-Dichrostachys cinerea degraded thornbush savannas towards the south under both scenarios. Conclusions: The model indicated the ability to classify and predict vegetation units to future climatic conditions. Half of the vegetation units are expected to undergo significant contraction. Overall, RCP8.5 conditions favour the proliferation of certain vegetation types, particularly Combretum collinum-Terminalia sericea broad-leafed savannas and Senegalia mellifera-Dichrostachys cinerea degraded thornbush savannas, potentially displacing other vegetation types.

Désiré est revenu
Authors: Cros Michèle 
Published: June 2024

Cet article constitue une mise en abyme mémorielle. Pour rendre hommage à Suzanne Lallemand et tout particulièrement à son fameux « bébé ancêtre Mossi », il est rendu compte du retour en ce monde de feu Désiré Tiatouré Pooda : « mon » propre père d’adoption en pays lobi au Burkina Faso. Désiré est revenu sous les traits d’un jeune enfant que l’on appelle Grand-père. Sa mère, Prudence, la fille aînée de la cinquième épouse de Désiré, raconte son avènement. Et, d’explications en riches commentaires – prenant même la forme d’une mini-bande dessinée –, bien d’autres de nos frères et sœurs du Lobi se révèlent également être des ancêtres… On le sait, même dans un échange d’aujourd’hui sur WhatsApp, « les morts ne sont pas morts ».
Dois-je aussi me mettre nu ?
Authors: Brun Clément 
Published: June 2024

Depuis 2002, il est possible de se baigner dans le port de Copenhague. Plébiscitée par les habitants, la baignade nous donne à voir un rapport nouveau entre eux et la ville, les espaces au bord de l’eau leur permettant de se relâcher et d’exposer leurs corps au soleil, au sol, au vent et à l’altérité. Se baigner dans la ville remplit notamment une fonction d’identifi­cation à une même culture nordique qui s’exprime à travers un rapport à la nudité décomplexé. Ces questions sont l’objet de notre travail de thèse en cours. Dans cet article, nous posons la question épistémologique de mon rapport personnel à l’enquête. À partir de travaux questionnant la subjectivité de l’enquêteur lorsqu’il doit participer à l’activité qu’il étudie, nous interrogeons les biais méthodologiques pouvant naître de la proximité avec son terrain. Qu’en est-il lorsqu’on étudie la baignade urbaine dans un pays étranger ? Est-on obligé de se baigner lorsqu’on a la baignade comme objet d’étude ? En étant observateur de situations où les corps sont dénudés et en participant nous-même à ces expériences d’altérité dénudée, cette enquête pousse-t-elle au voyeurisme ? Cet article se concentre sur les choix méthodologiques pour mener à bien une étude sur les pratiques de baignade urbaine. À partir de ce retour d’expérience, ce travail propose un questionnement personnel sur les effets d’enquête lorsque l’enquêteur est lié avec le terrain par filiation. Nous discuterons de l’importance de la participation aux activités durant l’obser­va­tion, pour permettre la production de données expérientielles utiles à l’enquêteur, mais aussi pour rentrer plus aisément en contact avec les enquêtés dans un terrain situé à l’étranger.

To evaluate the prevalence of abdominal obesity, hypercholesterolemia and hypertriglyceridemia and its associated factors in adults in a low income region. Cross-sectional, population-based study with probabilistic sample representative of a region of the Brazilian Northeast. Abdominal obesity was determined by waist circumference ≥ 80cm for women and ≥ 94cm for men. The classification considered for hypercholesterolemia was cholesterol ≥ 240mgdL-1 and for hypertriglyceridemia, triglycerides ≥ 200mgdL-1. The Poisson regression analysis evaluated the association between abdominal obesity, serum lipid changes and explanatory variables. A number of 260 adults, of the economic level C and D/E (≅96%) were evaluated. The prevalence of abdominal obesity, hypercholesterolemia and hypertriglyceridemia were 71.5, 21.2 and 26.9%, respectively. There was an association between abdominal obesity and female gender, age 50-59 years, overweight, and brown/black race was related as a protection factor. Hypercholesterolemia, was associated with subjects aged 50-59 years and ≥ 60 years, and hypertriglyceridemia was associated with overweight, aged ≥ 40years and smoker individuals. High prevalence of abdominal obesity, hypercholesterolemia and hypertriglyceridemia were found. From the age of 40 the subjects already had a risk factor for hypertriglyceridemia and 50 years for hypercholesterolemia and abdominal obesity. Abdominal obesity was also associated with overweight female individuals, and the brown/black race was connected to a protective factor. Smoking and overweight were associated with hypertriglyceridemia.
Optimal endotracheal cuff pressure in the intensive care setting: A pilot study
Authors: Poral Ananya Shree , Kovammal Shemin , Nalamate Rajarajeswari , Kurien Mary , Thomas Kurien 
Published: June 2024

Abstract

Background:
Endotracheal tube cuff pressure is clinically measured by “minimal occlusion (MOC) and minimal leak (MLK) techniques” by palpating and auscultating the neck for end-inspiratory “elimination” or “allowance” of subtle air leak, respectively. This study was done to determine the validity and reliability of MOC and MLK techniques, manometric endotracheal tube cuff-pressure measurement of 20–30 cm H2O being reference standard.

Materials and Methods:
A prospective, observational study was conducted in adult patients requiring positive pressure ventilation in the medical intensive care unit (ICU). Two investigators independently assessed MOC and MLK twice on days 2 and 3 of intubation. ICU registrar, unaware of earlier readings, noted manometric cuff-pressure within 5 min. Inter-observer reliability was calculated using intraclass correlation coeffiient (ICC). Validity of measurement was assessed using accepted reference standard of 20–30 cm H2O by manometer.

Results:
Sixty patients between 17 and 82 years, on positive pressure ventilation were evaluated twice, by two investigators resulting in 240 observations. Mean manometric pressures were 15.7 + 2.6 and 12.2 + 2.4 cm H2O using MOC and MLK techniques to maintain adequate ventilation. ICC measured for reliability was high at 0.69 and 0.67 for MOC and MLK techniques. Adequate ventilation was maintained in all patients and 57 of 60 (95%) were discharged alive without significant ventilatory complications.

Conclusions:
Cuff pressures needed to maintain effective positive pressure ventilation was well below the accepted levels of 20–30 cm of H2O in majority patients. MOC and MLK techniques have high reliability. The result of the study has the implications on ICU ventilatory care.
A preliminary observation on the effect of audio-visual speech perception in voiced cognates by Cypriot-Greek learners of English
Authors: Kkese Elena , Dimitriou Dimitra 
Published: June 2024

ABSTRACT
This study examines the use of audiovisual cues in the perception of sound contrasts which have a different phonemic status in the listeners’ L1 and L2. Voice-voiceless cognates differing in the distinctiveness of their visual gestures (/p/-/b/, /t/-/d/, and /k/-/g/) were presented to CG (Cypriot-Greek) learners of English in audio, visual, and audiovisual modalities. Overall identification rates were significantly higher audiovisually in the cases where the auditory and visual information matched (bimodal congruent condition) than in the audiovisual condition in which auditory and visual information did not match (bimodal incongruent condition) or in the audio or video alone condition for either contrast. The results point to the multisensory speech-specific mode of perception, which plays an important role in alleviating the majority of moderate-to-severe L2 difficulties. CG listeners’ success seems to depend upon the ability to relate what they see to what they hear.
Comparison of the loss of resistance syringe to pilot balloon palpation in achieving the recommended endotracheal cuff pressure of Filipino patients in a tertiary private hospital: a cross-over randomized controlled trial
Authors: Cua-Lim Jacqueline T , Lim William L , Chua Antonio H 
Published: June 2024

ABSTRACT

Objectives:
This study compared the effectiveness of the loss of resistance (LOR) syringe and pilot balloon palpation (PBP) methods in delivering adequate air volume to the endotracheal cuff of Filipino patients during intubation under general anesthesia.

Materials and Methods:
This was a crossover randomized controlled study involving intubated patients conducted in St. Luke’s Medical Center from August to September 2022. There were 68 patients enrolled. Two methods to estimate the endotracheal cuff pressures were used for each patient—the LOR syringe LOR method and the PBP method. The patients were randomized into 1:1 ratio allocation to one of the two sequences—LOR–PBP sequence and PBP–LOR sequence. Endotracheal cuff air volume for each method was recorded and classified as adequate if within the air volume range that achieved 20–30 cmH2O based on the cuff manometer.

Results:
The median lower and upper range of adequate endotracheal cuff air volume were 7 and 8 mL, respectively. The median air volume was 7 mL (range: 6–9 mL) and 8 mL (range: 6–9 mL) when PBP and LOR syringe methods were used, respectively. The proportion of patients who received adequate air volume was significantly higher when the LOR syringe was used (97.06%, 66/68) compared to the PBP method (48.53%, 33/68) (P = 0.002). None of the participants reported adverse effects for both methods.

Conclusions:
The LOR syringe method was superior to the PBP method in delivering adequate endotracheal cuff air volume. This method is a viable option to ensure adequacy of endotracheal cuff air volume.
