Published: May 2024

AbstractBackgroundWhile there exists an ample body of research in international contexts focused on the characterization and quantification of infertility psychological distress, the level of scholarly scrutiny directed towards this phenomenon within the context of China remains scant.Aims and ObjectivesTo investigate the formation and developmental processes of psychological distress associated with infertility and infertility treatment among women within the Chinese cultural context and to construct a theoretical framework that elucidates this phenomenon.DesignQualitative approach with grounded theory methodology.MethodsThis study was conducted within the reproductive medicine department of a tertiary‐level hospital located in central China from May to August 2023. Twenty‐seven women who experienced infertility and underwent assisted reproductive treatment (ART) were interviewed. The interview sessions spanned durations ranging from 20 min to 1 h and 35 min. Data analysis included open coding, axial coding and selective coding. The study is reported using the COREQ checklist.ResultsThe infertility psychological distress experienced by women undergoing ART is a socially constructed phenomenon influenced by a dynamic interplay of forces that construct and conciliate it. The formation and progression of infertility psychological distress are rooted in the process of self‐construction. A Middle‐Ranged Theory titled ‘self‐reconstruction under the dome of infertility and infertility treatment’ (SUDIT theory) was developed to explain this phenomenon. Within this framework, infertility psychological distress manifests across three distinct phases under the gambling of the constructive force and conciliative force: (1) distress of disrupting the former self; (2) distress linked to the struggling present self; and (3) the renewed‐self harmonized with distress.ConclusionsIt is imperative for healthcare professionals and policymakers to acknowledge the socially constructed nature of infertility psychological distress, and proactively implement measures aimed at ameliorating it.Patient or Public ContributionNo patient or public contribution.
No safe time window in malrotation and volvulus: A consecutive cohort study
Authors: Gibson Aimee , Silva Hobia , Bajaj Mohit , McBride Craig , Choo Kelvin , Morrison Shannon 
Published: May 2024

BackgroundMalrotation and volvulus classically present with bilious vomiting. It is more common earlier in life, but there are other causes of bile‐stained vomiting. This leads some clinicians to ‘watch and wait’. In the presence of a volvulus, this is potentially a fatal decision. It is not clear from the literature if there is a safe time window in which children can be observed in the hope of avoiding transfers or radiological investigations.AimTo determine whether time to identification and management of midgut volvulus correlated with morbidity and mortality; and whether there were patterns to transition of care.MethodsMulticentre, retrospective review of all children with malrotation ± volvulus at two tertiary children's hospitals in Brisbane from 2000 to 2012. Data collected included age at presentation, timing between symptom onset and presentation, radiological findings, and definitive surgical management. Outcomes included patient length of stay (LOS), total parenteral nutrition (TPN) duration, re‐operations and death.ResultsThere were 96 cases of malrotation identified, with 23 excluded (elective operation, insufficient data). Neonates made up 66% of included cases. Only 14% of cases were over 12 months old. Bilious vomiting or bile‐stained aspirates were the presenting symptoms in 71% (52). Overall mortality was 5.56%. Time from symptom onset to presentation or management was not significantly associated with morbidity or mortality. More than half (53%, 39/73) of patients received total parenteral nutrition; 20/39 for more than 10 days. Neonates and infants had a significantly higher rate of TPN compared with older children (P < 0.001). Those requiring TPN post‐operatively had a significantly higher mortality compared with those who did not (P = 0.02). Time from symptom onset to presentation or definitive management was not significantly associated with LOS, TPN duration, or need for re‐operation.ConclusionMalrotation remains a time‐critical diagnosis to secure and treat. Even a short duration of symptoms can be associated with high morbidity or mortality. There is no place for ‘watch and wait’ for such patients, and malrotation/volvulus should be emergently actively excluded with contrast studies.
Public infrastructure provision in the presence of terms‐of‐trade effects and tax competition
Authors: Zimmermann Karl J. 
Published: May 2024

AbstractThis paper analyses and compares the performance of resource taxes and capital taxes in financing public goods while considering the positive effects of public expenditure on firm productivity. It is motivated by Franks et al. (2017), who argue that the advantage of the resource tax consists in its potential to reap foreign resource rents. I employ an analytical general equilibrium framework of identical resource‐poor countries, where local firms use internationally mobile capital and a net imported resource in production as well as local public infrastructure. The latter is financed solely by either taxing the input of the resource or capital. The choice of the policy instrument is exogenous to policy makers and symmetric across countries. I find that expenditure on infrastructure renders the impact of fiscal policy on the terms of trade ambiguous under resource taxation and negative under capital taxation. Moreover, public expenditure weakens the outflow of factors moderating the deficit of public spending caused by tax competition. This holds for both policy scenarios. Considering both effects simultaneously, resource taxation cannot generally be identified as the policy to provide higher provision or efficiency. A numerical exercise shows cases for higher provision of either policy.

Published: May 2024

AbstractPotato black dot became an increasingly severe disease in Inner Mongolia, mainly infecting tubers, causing silvery to brown lesions on tuber skin with poorly defined margins and forming black sclerotia later as a sign of skin blemish diseases which significantly affected the yield and fresh market. The C11 and E21 strains isolated from symptomatic tubers of Harqin and Dalate counties were both identified as Colletotrichum coccodes by morphological and molecular identification. Tubers showing silver or brown scurf and black dot on skin were consistent with symptomatic samples collecting from the field in pathogenicity test. This study for pathogenic identification ascertained a tricky disease of potato in Inner Mongolia of China which will lay the foundation for subsequent studies on disease control.

Published: May 2024

AbstractIn April 2023, leaf curl, crinkling symptoms were found on Conyza canadensis plants around tobacco fields located at Yuxi, Yunan province, China. PCR detection with genus‐specific primers showed that symptomatic C. canadensis plants was infected by begomovirus. The full‐length viral components and satellite molecules from the diseased C. canadensis (YN‐2023) were obtained by enrichment of circular DNA with rolling circle amplification, restriction enzyme digestion, cloning, and DNA sequencing. The viral component (2, 750 nt, OR509733) shared the highest nt identity at 92.4% to tobacco leaf curl Yunnan virus isolate YN5741 (TbLCYNV‐YN5741 [CN:Yn:Age:16], MN218671). A satellite molecule (1, 339 nt, OR509734) shared the highest nt identity at 86.5% to tobacco curly shoot betasatellite isolate Y115 (TbCSB‐Y115 [CN:Yn:03], AJ457822). Another satellite molecule (1, 357 nt, OR509735) shared the highest nt identity at 94.2% to ageratum yellow vein Singapore alphasatellite (AYVSGA‐[Singapore:1998], NC003414). Based on the threshold for classification of Begomovirus, Betasatellite, Alphasatellite, YN‐2023 was a new strain of TbLCYNV and associated with TbCSB and AYVSGA. To our best knowledge, this is the first report that C. canadensis is a natural host of TbLCYNV.

AbstractBackgroundHemodynamic classification of pulmonary hypertension (PH) has important clinical implications. However, only a few echocardiographic variables have been used to hemodynamically classify PH in dogs.ObjectiveTo evaluate the echocardiographic pulmonary to left atrial ratio index (ePLAR) in dogs with PH.AnimalsForty‐six dogs with intermediate to high probability of PH.MethodsCross‐sectional study. Variables were compared between dogs with precapillary PH [PrePH (n = 24)] vs postcapillary PH [PostPH (n = 22)], and with combined PH [CombPH (n = 14)] vs isolated PH [IsoPH (n = 8)] using the t‐, Mann‐Whitney, Pearson's Chi, or Fisher's exact test. The receiver operating characteristic curve and Youden index were used to identify the optimal ePLAR cutoff value to differentiate among the groups, intraclass correlation coefficients (ICC) were used to determine the reliability of measurements.ResultsThe mean (SD) ePLAR of the PrePH was higher than that of the PostPH group [0.36 (0.13) vs 0.26 (0.09), respectively; P = .005]. The median (interquartile range) ePLAR of the CombPH was higher than that of the IsoPH subgroup [0.29 (0.24‐0.38), vs 0.20 (0.16‐0.23), respectively; P = .001]. The best cutoff value of ePLAR for identifying IsoPH was <0.245 [AUC at cutoff point = 0.86; sensitivity (95% confidence interval [CI]) = 0.71 (0.47‐0.95); specificity (95% CI) = 1 (0.76‐1)]. The ICC analysis indicated a high degree of reliability.Conclusions and Clinical ImportanceePLAR can be considered a valid noninvasive variable to hemodynamically classify PH in dogs with an intermediate to high probability of PH. Assessment of ePLAR can be useful in the therapeutic management of PH in dogs.
Less work and higher tax can raise wellbeing
Authors: FitzRoy Felix , Jin Jim 
Published: May 2024

AbstractWorktime has been falling slowly though real wages have risen dramatically. We show that in a general equilibrium model with CES utility and production functions, worktime falls with real wages if and only if the elasticity of substitution between consumption and leisure is less than that between capital and labour, but always rises with labour's income share and concerns with relative income. While a falling labour share may not reduce worktime due to market inflexibility, stronger income comparison increases inefficient overwork. Hence, more flexibility, higher income taxes and a basic income are needed to reduce working hours and raise social welfare.
Black cemeteries as archives
Authors: Klugh Elgin L. 
Published: May 2024

AbstractThis commentary argues for the recognition and preservation of historic black cemeteries as primary components within associated archival networks. Such networks include death certificates, historic newspapers, maps, church records, oral histories, and a host of other conventional and nonconventional sources. These sources, when viewed in tandem, work to corroborate and provide insights into other sources and spur new investigations. As the primary components of such networks, both extant cemeteries and burial grounds hidden within the landscape can be utilized as active sites for research, education, and commemoration. This place‐based remembrance encourages the identification and retrieval of local histories and works to increase the number of individuals interested and involved in preservation efforts.
Renal thrombotic microangiopathy is associated with poor renal survival in children with immunoglobulin A nephropathy

Published: May 2024

AbstractAimThe aim of this study was to examine the clinical and pathological characteristics as well as the prognosis of immunoglobulin A nephropathy (IgAN) accompanied by renal thrombotic microangiopathy (rTMA) in paediatric patients.MethodsAfter balancing epidemiological characteristics and pathological types between groups, 427 patients (rTMA group: 23, non‐rTMA group: 46) were included. The clinical and pathological features, prognosis and clinical risk factors of the two groups were analysed.ResultsIgAN‐rTMA children showed more severe clinical and pathological manifestations. The findings from the logistic regression analysis indicated that hypercellularity 1 (E1) (HR: 0.805, 95% CI: 0.763 ~ 1.452, P = .016), endocapillary proliferation (HR: 1.214, 95% CI: 0.093 ~ 4.815, P = .025) and C3 staining (HR: 7.554, 95% CI: 2.563 ~ 15.729, P = .037) were the risk factors for rTMA in children with IgAN. The renal survival in rTMA group was lower than non‐rTMA group (χ2 = 18.467, P = .000). Cox regression analysis showed that E1 (HR: 7.441, 95% CI: 1.095 ~ 10.768, P = .037), C3 disposition (HR: 3.414, 95% CI: 0.834 ~ 11.578, P = .027) and rTMA (HR: 8.918, 95% CI: 1.032 ~ 16.754, P = .041) were identified as independent risk factors for the development of end‐stage renal disease (ESRD).ConclusionThe presence of rTMA had a significant impact on the severity and prognosis of IgAN. And rTMA has been identified as an independent risk factor for the development of renal failure in children diagnosed with IgAN.image
Nectar and floral morphology differ in evolutionary potential in novel pollination environments
Authors: Romero‐Bravo Andrés , Castellanos Maria Clara 
Published: May 2024

Summary

Plants can evolve rapidly after pollinator changes, but the response of different floral traits to novel selection can vary. Floral morphology is often expected to show high integration to maintain pollination accuracy, while nectar traits can be more environmentally sensitive. The relative role of genetic correlations and phenotypic plasticity (PP) in floral evolution remains unclear, particularly for nectar traits, and can be studied in the context of recent pollinator changes.

Digitalis purpurea shows rapid recent evolution of corolla morphology but not nectar traits following a range expansion with hummingbirds added as pollinators. We use this species to compare PP, heritability, evolvability and integration of floral morphology and nectar in a common garden.

Morphological traits showed higher heritability than nectar traits, and the proximal section of the corolla, which regulates access to nectar and underwent rapid change in introduced populations, presented lower integration than the rest of the floral phenotype. Nectar was more plastic than morphology, driven by highly plastic sugar concentration. Nectar production rate showed high potential to respond to selection.

These results explain the differential rapid evolution of floral traits previously observed in this species and show how intrafloral modularity determines variable evolutionary potential in morphological and nectar traits.

Summary

Cultivated spinach (Spinacia oleracea) is a dioecious species. We report high‐quality genome sequences for its two closest wild relatives, Spinacia turkestanica and Spinacia tetrandra, which are also dioecious, and are used to study the genetics of spinach domestication.

Using a combination of genomic approaches, we assembled genomes of both these species and analyzed them in comparison with the previously assembled S. oleracea genome.

These species diverged c. 6.3 million years ago (Ma), while cultivated spinach split from S. turkestanica 0.8 Ma. In all three species, all six chromosomes include very large gene‐poor, repeat‐rich regions, which, in S. oleracea, are pericentromeric regions with very low recombination rates in both male and female genetic maps. We describe population genomic evidence that the similar regions in the wild species also recombine rarely. We characterized 282 structural variants (SVs) that have been selected during domestication. These regions include genes associated with leaf margin type and flowering time. We also describe evidence that the downy mildew resistance loci of cultivated spinach are derived from introgression from both wild spinach species.

Collectively, this study reveals the genome architecture of spinach assemblies and highlights the importance of SVs during the domestication of cultivated spinach.
Spindle cell carcinoma of the maxillary antrum presenting in the oral cavity: A case report
Authors: O'Gorman Conor , Tran Christina , Willis Amanda 
Published: May 2024

AbstractBackgroundSpindle cell carcinoma is a rare biphasic malignancy consisting of epithelial and mesenchymal components. It is a poorly differentiated variant of squamous cell carcinoma accounting for less than 2% of intraoral tumours, with only 69 cases reported in the literature. Clinical presentation may vary from exophytic tumours to infiltrating ulceration in the oral mucosa. Atypical presentation and erractic behaviour of these tumours mean management can be challenging, therefore prompt diagnosis and treatment are required to address the significant morbidity and mortality associated with this disease.Case PresentationA 49‐year‐old patient presented to the oral medicine clinic reporting pain affecting the left side of their palate and cheek. Prior to their attendance, they were assessed by their general medical practitioner and neurologist; however, a trial of various medications resulted in no improvement in their symptoms. Intra‐oral examination revealed an ulcer in the left hard palate with underlying visible maxillary bone. A subsequent biopsy confirmed the diagnosis of spindle cell carcinoma, and the patient received radiotherapy with adjuvant chemotherapy. Further imaging revealed distant metastasis in the right lung and treatment was changed to palliative immunotherapy. Follow‐up imaging has shown lung nodules to be stable, and the patient remains under review with the regional head and neck cancer team.ConclusionsWe report a rare case of intra‐oral spindle cell carcinoma diagnosed from a palatal lesion, which has only been reported in four cases previously at this site. Despite preceding encounters with multiple medical professionals, it is not clear whether an intra‐oral examination was carried out which may have established the diagnosis earlier. It emphasizes the importance of full head & neck examination, including intraoral examination in presentations of unexplained and intractable orofacial pain.

Published: May 2024

ObjectiveNontraumatic osteonecrosis of the femoral head (ONFH) is commonly encountered in orthopedics. Without early clinical intervention, most patients with peri‐collapse of the ONFH will develop femoral head necrosis and eventually require hip replacement surgery. The aim of this study is to evaluate clinical outcomes in patients with ONFH who underwent “light bulb” core decompression (CD) with arthroscopic assistance and to compare them with the outcomes of those treated with traditional procedures.MethodsA retrospective review of patients with Stage II and IIIA (Peri‐collapse) radiographic findings based on the Association Research Circulation Osseous (ARCO) stage for ONFH who underwent “light bulb” CD with or without arthroscopic assistance by a single‐surgeon team between March 2014 and December 2018 was performed. All patients were followed up for a minimum of 2 years. The visual analogue scale (VAS) pain score, Harris hip score (HHS), and radiological imaging were evaluated. The categorical parameters were analyzed by chi‐square test and the continuous variables conforming to a normal distribution were analyzed by Student's t‐test.ResultsThe study included a total of 39 patients (18 and 21 patients in the with and without arthroscopic assistance groups, respectively), with a mean age of 40.3 years and a mean follow‐up of 22.2 months. Overall, there was a better VAS score in the arthroscopic assistance group than in the control group (p < 0.05), There was a significant difference in HHS (80.1 ± 9.2 vs 75.1 ± 12.7) at the last follow‐up (p < 0.05). The rate of good and excellent outcomes was 94%. Similarly, there was no significant difference in the total rate of complications or conversion to THA.ConclusionWith arthroscopic assistance, “light bulb” CD could be achieved via hip arthroscopy with less trauma, and it offered the opportunity for more precise evaluation and monitoring for therapy and yielded better VAS scores after surgery and better hip function outcomes at the last follow‐up.
Socrates' Final Argument in Apology
Authors: Taylor Mark Robert 
Published: May 2024

AbstractSocrates provides an argument at the end of the Apology that he believes gives hope that death is a blessing. This argument, grounded on the claim that death is one of two things, has been the subject of much derision and some recent defense. In this essay, I build on the work of other sympathetic commentators to show that Socrates' argument, when taken in context, not only makes good sense, but unifies Socrates' speech into a cohesive exhortation toward virtue.
Who seeks care and for what reasons at a nurse‐led walk‐in center in an immigrant‐dense area—A quantitative survey
Authors: Hjelm Katarina , Hadziabdic Emina 
Published: May 2024

AbstractObjectiveTo describe who seeks care and for what reasons at a nurse‐led primary healthcare walk‐in center in an immigrant‐dense area. Studies evaluating the use of nurse‐led walk‐in centers in primary healthcare, emphasizing migrants, are limited. Due to language difficulties and a healthcare system based on telephone consultations, access to care is limited/problematic for the care seeker and the healthcare provider. The center aims to provide migrants and Swedish‐born persons equal access to primary healthcare. Care was integrated into a healthcare center with a multi‐professional environment, offering Arabic and Somali interpreters.DesignCross‐sectional descriptive registry study.SampleAll consecutive patients visiting during 1‐month.ResultsMost individuals (70%) seeking care at the nurse‐led walk‐in center were non‐European migrants from Syria, Iraq and Somalia, but Swedish‐born persons (30%) also consulted the clinic. Women, middle‐aged, and lower‐educated patients dominated. Reasons for seeking care included different kinds of pain, ear/nose/throat issues, and skin problems. Migrants prioritized non‐specific pain and dizziness/headaches, while Swedes sought help primarily for upper respiratory tract infections. About 25% of the migrants needed interpreters, mostly females.ConclusionThe nurse‐led walk‐in center provides accessible care in a multi‐professional team, if needed, serving migrants and Swedish‐born persons, promoting equal healthcare for all.
