Anal canal coronal-sagittal ratio: a novel parameter for diagnosing pelvic floor injury in two-dimensional transanal ultrasound

Ann Coloproctol. 2022 Nov 10. doi: 10.3393/ac.2022.00129.0018. Online ahead of print.

ABSTRACT

PURPOSE: Pelvic floor injury diagnosis using 3-dimensional (3D) pelvic floor ultrasound or magnetic resonance imaging is unfeasible in many clinics. We assessed the efficacy of a novel diagnostic parameter, the anal canal coronal-sagittal (CS) ratio, for pelvic floor injury on 2-dimensional [2D] transanal ultrasound.

METHODS: This retrospective study analyzed the data of 126 female patients who underwent 3D pelvic floor ultrasound (including 2D transanal ultrasound) at a pelvic floor center between August and December 2020. The anal canal CS ratio on 2D transanal ultrasound and pelvic floor avulsion injury measurements were recorded for all patients.

RESULTS: A cutoff anal canal CS ratio of 1.15 was obtained using receiver operating characteristic analysis (sensitivity, 0.820; specificity, 0.763; and area under the curve, 0.838). Patients were categorized into the anal canal CS ratio ≥1.15 and the anal canal CS ratio <1.15 groups. Bilateral pelvic floor avulsion was more common in the anal canal CS ratio ≥1.15 group (n=35, 56.5%), and the incidence of pelvic floor avulsion was significantly different between the 2 groups (P=0.001). Existing parameters of pelvic floor injury, including minimal levator hiatus (P=0.001), levator plate descent angle (P=0.001), and levator ani deficiency score (P=0.001), were statistically different between the 2 groups.

CONCLUSION: The anal canal CS ratio was an efficient novel parameter that indirectly detected pelvic floor injury in 2D transanal ultrasound. It is a potential alternative indicator for pelvic floor injury on the widely popular 2D transanal ultrasound.

Context-Dependent Learning of Linguistic Disjunction

J Child Lang. 2022 Nov 10:1-36. doi: 10.1017/S0305000922000502. Online ahead of print.

ABSTRACT

What are the constraints, cues, and mechanisms that help learners create successful word-meaning mappings? This study takes up linguistic disjunction and looks at cues and mechanisms that can help children learn the meaning of or. We first used a large corpus of parent-child interactions to collect statistics on or uses. Children started producing or between 18-30 months and by 42 months, their rate of production reached a plateau. Second, we annotated for the interpretation of disjunction in child-directed speech. Parents used or mostly as exclusive disjunction, typically accompanied by rise-fall intonation and logically inconsistent disjuncts. But when these two cues were absent, disjunction was generally not exclusive. Our computational modeling suggests that an ideal learner could successfully interpret an English disjunction (as exclusive or not) by mapping forms to meanings after partitioning the input according to the intonational and logical cues available in child-directed speech.

Self-care in migrants with type 2 diabetes, during the COVID-19 pandemic

J Nurs Scholarsh. 2022 Nov 9. doi: 10.1111/jnu.12842. Online ahead of print.

ABSTRACT

INTRODUCTION: Type 2 diabetes is increasing globally and particularly affects vulnerable groups in society, such as migrants. Research shows that type 2 diabetes is a risk factor for severe illness when infected with COVID-19. Diabetes-related complications can be prevented with good glycaemic control. In addition, good glycaemic control has been shown to be an important cornerstone for preventing severe illness in individuals infected with COVID-19. In order to maintain good glycaemic control, self-care is needed. The purpose of this article is to describe self-care maintenance and possible changes in self-care maintenance and to explore factors related to unchanged self-care maintenance in migrant patients with type 2 diabetes during the COVID-19 pandemic. The second aim is to describe well-being, social support, and the need for support from healthcare services during the COVID-19 pandemic in migrant patients with type 2 diabetes.

DESIGN/METHOD: A triangulation design with cross-sectional data collection was used. Both quantitative and qualitative data were collected and interpreted together in a triangulation design. Patients were selected by a diabetes nurse from a computer system at a health center in south-eastern Sweden and invited to participate in the study. A questionnaire was translated into the languages most commonly used at the clinic and sent out to 332 migrant patients who had been diagnosed with type 2 diabetes and treated in primary care. This questionnaire assessed self-care maintenance for diabetes (questions inspired by the Self-Care of Diabetes Inventory), with questions added to every item to assess changes during the pandemic. When changes occurred, we asked the participants to elaborate. Open-ended questions asked the participants how they would like to receive information when there are changes in their healthcare. Descriptive statistical analyses were used for the quantitative data and qualitative data was analyzed using a directed approach to content analysis.

RESULTS: In total, 79 participants answered the questionnaire (mean age 69 ± 11, 51% male, 47% born in the Middle East). Of these, 76% stated a change in self-care. More than half (58%) stated changes in maintaining an active lifestyle, 40% had changed their physical exercise, and 38% had changed their behavior to avoid getting sick. Participants said that this change was due to staying at home or canceling social activities because they feared meeting people during the pandemic. Others were more physically active than before on a regular basis during the pandemic due to taking walks to get fit, as a precaution related to COVID-19, and having greater awareness about how to avoid getting sick. Approximately one-quarter of the participants experienced a change in contact with healthcare due to poorer access to care, with fewer doctors’ appointments and care being postponed during the pandemic. More than half (58%) would like to receive information about healthcare changes by a letter in the regular mail. Social support had changed for 35% of the participants, with less support from family and friends due to the risk of being infected with COVID-19.

CONCLUSION: The COVID-19 pandemic led to societal restrictions that changed the way of life for many individuals. Migrant patients with type 2 diabetes, who are already a vulnerable group regarding self-care, had difficulties in maintaining good living habits during the pandemic. During crises such as COVID-19, support with self-care, such as closer contact with healthcare providers, is vital.

CLINICAL RELEVANCE: Knowledge about how the COVID-19 pandemic has affected migrants with type 2 diabetes can be used to support healthcare providers in identifying individuals who are at high risk of suffering from the consequences of their diabetes associated with the pandemic.

Combined use of shear-wave elastography and Doppler ultrasonography in equivocal fibroepithelial lesions of the breast diagnosed by core needle biopsy

Ultrasonography. 2022 May 23. doi: 10.14366/usg.22008. Online ahead of print.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the diagnostic value of shear-wave elastography (SWE) combined with Doppler ultrasonography (US) in selecting equivocal breast fibroepithelial lesions (FELs) for follow-up without further excision.

METHODS: A retrospective analysis was conducted of 88 patients with equivocal breast FELs (FELs with the possibility of both fibroadenoma [FA] and phyllodes tumor [PT]) diagnosed by core needle biopsy (CNB). For post-CNB treatment, surgical or vacuum-assisted excision was performed on 88 equivocal FELs, of which 56 were diagnosed as FAs and 32 as PTs on histopathology. Mean elasticity (Emean) and vascularity were determined using SWE and Doppler US. The diagnostic performances of B-mode US, SWE, and Doppler US were calculated to differentiate FAs and PTs in the excised equivocal FELs.

RESULTS: In the excised equivocal FELs diagnosed by CNB, FAs showed significantly lower median Emean values (36.4 vs. 66.7 kPa, P=0.005) and more frequent low vascularity (0-1 vessel flow signal) (P<0.001) than PTs. For the differentiation of FAs and PTs, the combination of Emean of >60.9 kPa and high vascularity (≥2 vessel flows) showed a sensitivity and negative predictive value of 100%, as well as better performance in other diagnostic values than B-mode US alone (Breast Imaging Reporting and Data System ≥4A) (all P<0.05).

CONCLUSION: Equivocal breast FELs showing both low elasticity and low vascularity were not upgraded to PTs upon further excision. Therefore, the combination of SWE and color Doppler US mode might help select patients with equivocal FELs for whom further excision is unnecessary.

Comorbidities associated with high-risk obstructive sleep apnea based on the STOP-BANG questionnaire: a nationwide population-based study

Korean J Intern Med. 2022 Nov 10. doi: 10.3904/kjim.2022.198. Online ahead of print.

ABSTRACT

BACKGROUND/AIMS: We investigated the prevalence, associated factors, and comorbidities of high-risk obstructive sleep apnea (OSA) as determined by the STOP-BANG questionnaire in a Korean adult population.

METHODS: Data were obtained from 7,650 adults (aged ≥ 40 years) who participated in the Korea National Health and Nutrition Examination Survey (2019-2020). Multiple logistic regression analyses were used to evaluate the association of socioeconomic status, lifestyle related factors, and comorbidities with high-risk OSA (STOP-BANG score, 5-8).

RESULTS: The prevalence of high-risk OSA according to the STOP-BANG questionnaire was 12.0 %. Older age, male, current smoking, heavy alcohol consumption, and more comorbidities were associated with higher STOP-BANG scores. In multivariable adjusted analysis, diabetes mellitus (DM) (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.25 to 1.97), hypertension (OR, 4.81; 95% CI, 3.88 to 5.97), and obesity (OR, 2.02; 95% CI, 1.60 to 2.56) were associated with high risk of OSA, and when hypertension, DM, and obesity were combined, the risk increased synergistically (OR, 3.88; 95% CI, 2.94 to 5.11).

CONCLUSIONS: According to the STOP-BANG questionnaire, the high risk of OSA was more common in males, and was associated with chronic metabolic disease, particularly in those with DM, hypertension, and obesity combined. Active OSA screening, prevention, and management may be beneficial to improving health outcomes related to OSA in these populations.

Widely Targeted Metabolomics Analysis of Different Parts of Kudzu

Biomed Chromatogr. 2022 Nov 9:e5545. doi: 10.1002/bmc.5545. Online ahead of print.

ABSTRACT

Pueraria lobata is a traditional medicinal and edible plant, its root is often used as a nutritional supplement, but its stems and leaves are often discarded. In this study, the types and contents of compounds in roots, stems and leaves of kudzu were studied by ultra-high-performance liquid chromatography electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS). A total of 446 metabolites were identified, which were mainly divided into 8 categories, forty unique compounds were detected in roots. Multivariate statistical analysis showed that there were significant differences in the contents of metabolites in the roots, stems and leaves of kudzu, and the most significant differences were found in the roots and stems. Most flavonoids and terpenoids accumulated in roots, while alkaloids, flavonoid glycosides, lignans and coumarins accumulated in stems and leaves. In addition, isoflavones accumulated least in stems and most in roots. These results improved our understanding of the accumulation of metabolites in kudzu and provided a reference for the full study of the medicinal value of different parts of kudzu.

Relationships between cataract surgery patient-perceived discharge teaching quality, discharge readiness, and post-discharge outcomes: a cross-sectional study based on regression modeling analysis

Ophthalmic Res. 2022 Nov 9. doi: 10.1159/000527958. Online ahead of print.

ABSTRACT

INTRODUCTION: A short hospital stay makes discharge planning services especially critical for patients undergoing cataract surgery. Studies on discharge teaching quality, discharge readiness, and post-discharge outcomes for patients are lacking with cataracts. Our study aimed to explore the relationships between the perceived discharge teaching quality, discharge readiness, and post-discharge outcomes of cataract surgery patients and to conduct a differential analysis between inpatient and day ward patients.

METHODS: We recruited 387 patients from the ophthalmology ward of a top-tier hospital in western China through convenience sampling. Data were collected on the day of discharge and at 2 weeks post-discharge. Statistical methods included multiple linear regression analysis, chi-square test, and the Mann-Whitney U test.

RESULTS: Regression models indicated that discharge teaching quality was the key factor of discharge readiness, while post-discharge outcomes were influenced by discharge readiness and discharge teaching quality. Further, inpatients’ discharge teaching quality, discharge readiness, and post-discharge subjective feelings were better than those of day ward patients.

CONCLUSIONS: The effect of discharge planning services on patients undergoing cataract surgery was generally satisfactory. High-quality discharge teaching can enhance patients’ discharge readiness, further improving their post-discharge outcomes. When conducting discharge teaching, day ward medical staff should pay more attention to patients’ demands and explore a more effective teaching delivery method.

Single Protein Detection and Imaging with Evanescent Scattering Microscopy

Bio Protoc. 2022 Oct 20;12(20):e4530. doi: 10.21769/BioProtoc.4530. eCollection 2022 Oct 20.

ABSTRACT

Single-molecule measurements provide statistical distributions of molecular properties, in addition to the ensemble averages. Evanescent detection approaches have been widely used for single-molecule detection because the evanescent field can significantly enhance the light-analyte interaction and reduce the background noise. However, current evanescent single-molecule detection systems mostly require specially designed sensing components. Here, we show that single proteins can be imaged on a plain cover glass surface by detecting the evanescent waves scattered by the target molecules. This allows us to quantify the protein-antibody interactions at the single-molecule level. This protocol describes a label-free single-molecule imaging approach with conventional consumables and may pave the road for detecting single molecules with commercial optical microscopy.

Investigating sex differences in T regulatory cells from cisgender and transgender healthy individuals and patients with autoimmune inflammatory disease: a cross-sectional study

Lancet Rheumatol. 2022 Aug 31;4(10):e710-e724. doi: 10.1016/S2665-9913(22)00198-9. eCollection 2022 Oct.

ABSTRACT

BACKGROUND: Sexual dimorphisms, which vary depending on age group and pubertal status, have been described across both the innate and adaptive immune system. We explored the influence of sex hormones on immune phenotype in the context of adolescent health and autoimmunity.

METHODS: In this cross-sectional study, healthy, post-pubertal cisgender individuals (aged 16-25 years); healthy, pre-pubertal cisgender individuals (aged 6-11 years); transgender individuals (aged 18-19 years) undergoing gender-affirming treatment (testosterone in individuals assigned female sex at birth and oestradiol in individuals assigned male sex at birth); and post-pubertal cisgender individuals (aged 14-25 years) with juvenile-onset systemic lupus erythematosus (SLE) age-matched to cisgender individuals without juvenile-onset SLE were eligible for inclusion. Frequencies of 28 immune-cell subsets (including different T cell, B cell, and monocyte subsets) from each participant were measured in peripheral blood mononuclear cells by flow cytometry and analysed by balanced random forest machine learning. RNA-sequencing was used to compare sex and gender differences in regulatory T (Treg) cell phenotype between participants with juvenile-onset SLE, age-matched cis-gender participants without the disease, and age matched transgender individuals on gender-affirming sex hormone treatment. Differentially expressed genes were analysed by cluster and pathway analysis. Suppression assays assessed the anti-inflammatory function of Treg cells in vitro.

FINDINGS: Between Sept 5, 2012, and Nov 6, 2019, peripheral blood was collected from 39 individuals in the post-pubertal group (17 [44%] cisgender men, mean age 18·76 years [SD 2·66]; 22 [56%] cisgender women, mean age 18·59 years [2·81]), 14 children in the cisgender pre-pubertal group (seven [50%] cisgender boys, mean age 8·90 [1·66]; seven [50%] cisgender girls, mean age 8·40 [1·58]), ten people in the transgender group (five [50%] transgender men, mean age 18·20 years [0·47]; five [50%] transgender women, mean age 18·70 years [0·55]), and 35 people in the juvenile-onset SLE group (12 [34%] cisgender men, mean age 18·58 years [2·35]; 23 [66%] cisgender women, mean age 19·48 [3·08]). Statistically significantly elevated frequencies of Treg cells were one of the top immune-cell features differentiating young post-pubertal cisgender men from similarly aged cisgender women (p=0·0097). Treg cells from young cisgender men had a statistically significantly increased suppressive capacity in vitro compared with those from cisgender women and a distinct transcriptomic signature significantly enriched for genes in the PI3K-AKT signalling pathway. Gender-affirming sex hormones in transgender men and transgender women induced multiple statistically significant changes in the Treg-cell transcriptome, many of which enriched functional pathways that overlapped with those altered between cisgender men and cisgender women, highlighting a hormonal influence on Treg-cell function by gender. Finally, sex differences in Treg-cell frequency were absent and suppressive capacity was reversed in patients with juvenile-onset SLE, but sex differences in Treg-cell transcriptional signatures were significantly more pronounced in patients with juvenile-onset SLE compared with individuals without juvenile-onset SLE, suggesting that sex hormone signalling could be dysregulated in autoimmunity.

INTERPRETATION: Sex-chromosomes and hormones might drive changes in Treg-cell frequency and function. Young post-pubertal men have a more anti-inflammatory Treg-cell profile, which could explain inflammatory disease susceptibilities, and inform sex-tailored therapeutic strategies.

‘As safe as houses; the risk of childhood lead exposure from housing in England and implications for public health’

BMC Public Health. 2022 Nov 9;22(1):2052. doi: 10.1186/s12889-022-14350-y.

ABSTRACT

BACKGROUND AND AIM: Exposure to lead can harm a child’s health, including damage to the nervous system, delayed growth, hearing loss, and many other adverse health effects, as well as implications for social, economic, educational and social well-being. Lead exposure in children is still a concern and cases require public health management to find the exposure source and interrupt the exposure pathway. Housing characteristics can indicate the presence of lead-contaminated paint and leaded water supply pipes. We aimed to explore the relationship between housing characteristics and elevated blood lead concentration (BLC) in children in England.

METHODS: We used a retrospective cohort design and included all cases of lead exposure in children reported to the UK Health Security Agency between 2014 and 2020 via surveillance. A case was a child aged under 16 years, resident in England, BLC of ≥ 0.48 μmol/L (10 µg/dL) and referred for public health management. We collected case demographic details and housing characteristics (age and type). We explored associations between elevated BLC and risk factors, using generalised linear mixed effects models and compared cases’ housing type to that expected nationally.

RESULTS: Two hundred and sixty-six out of 290 cases met the case definition. There was no difference in BLCs between genders, age groups, deprivation, and housing type. After adjusting for reporting source, housing age and type, cases residing in housing built pre-1976 had a BLC of 0.32 (95%CI 0.02, 0.63) µmols/L (6.63 (95%CI 0.42, 13.0) µg/dL) higher than cases living in housing built after this time. Cases were 1.68 times more likely to be living in terraced housing (housing adjoined to one another) than other children and less likely to live in apartments and detached properties.

CONCLUSION: This study suggests an association between housing characteristics and BLC in children. Housing age and type may act as a proxy for lead exposure risk through exposure to leaded paint, lead water pipes, and lead contaminated dust from indoor and outdoor sources. Public health action should consider targeting families more at risk in older housing by raising awareness of the potential presence of lead pipes and paint. Interventions should include working with wider stakeholders including other housing and environmental professionals, the private sector, as well as parents and carers.
