Navigating changes: A qualitative study exploring the health-related quality of life of breast cancer survivors during the coronavirus disease 2019 pandemic.

AIMS: To explore the impact of the coronavirus disease 2019 pandemic on the health-related quality of life (HRQoL) of breast cancer survivors. DESIGN: We utilized a qualitative descriptive approach to facilitate interviews among 25 participants, all of whom are survivors of breast cancer and have received treatment in Hong Kong within the preceding 3 years. METHODS: Content analysis was performed to understand how patients' HRQoL views and experiences changed during coronavirus disease 2019 pandemic. RESULTS: The results included six themes delineating the impact of the coronavirus disease 2019 pandemic: (i) survivor sensitivities in pandemic times, (ii) coping and conditioning in pandemic times, (iii) transforming work and home dynamics in pandemic times, (iv) cognitive resilience and adaptation to the COVID-19 protective measures, (v) social resilience in pandemic times and (vi) healthcare adaptation and coping in pandemic times. CONCLUSION: This study provides insights into the experiences and challenges of breast cancer survivors during the coronavirus disease 2019 pandemic. Some survivors had new physical and psychological symptoms, including fear and anxiety, isolation, pain, lymphoedema and burnout, which potentially have long-term impact upon HRQoL. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: This study highlights the unique challenges faced by breast cancer survivors during the coronavirus disease 2019 pandemic, including accessing healthcare services and the impact of social isolation. Healthcare providers should consider the holistic needs of breast cancer survivors in the provision of health care and develop supportive interventions, including telehealth services and online support groups, to address these challenges and improve their HRQoL. IMPACT: Surgery aimed at treating breast cancer or reducing its risk generally influences the appearance of breast areas and donor sites. The continuing effects of these changes on body image and HRQoL are well-reported, although studies have ineffectively examined the initial experiences of women regarding their postoperative appearance, particularly during the pandemic. REPORTING METHOD: The checklist of consolidated criteria for reporting qualitative research (COREQ) was utilized. PATIENT OR PUBLIC CONTRIBUTION: A small selection on breast cancer survivors contributed to the design of this study, in particular the content of the semi-structured interviews.

Validation of a real-time PCR panel for detection and quantification of nine pathogens commonly associated with canine infectious respiratory disease.

Canine infectious respiratory disease (CIRD) is a complicated respiratory syndrome in dogs [1], [2], [3]. A panel PCR was developed [4] to detect nine pathogens commonly associated with CIRD: Mycoplasma cynos, Mycoplasma canis, Bordetella bronchiseptica; canine adenovirus type 2, canine herpesvirus 1, canine parainfluenza virus, canine distemper virus, canine influenza virus and canine respiratory coronavirus [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16]. To evaluate diagnostic performance of the assay, 740 nasal swab and lung tissue samples were collected and tested with the new assay, and compared to an older version of the assay detecting the same pathogens except that it does not differentiate the two Mycoplasma species. Results indicated that the new assay had the same level of specificity, but with higher diagnostic sensitivity and had identified additional samples with potential co-infections. To confirm the new assay is detecting the correct pathogens, samples with discrepant results between the two assays were sequence-confirmed. Spiking a high concertation target to samples carrying lower concentrations of other targets was carried out and the results demonstrated that there was no apparent interference among targets in the same PCR reaction. Another spike-in experiment was used to determine detection sensitivity between nasal swab and lung tissue samples, and similar results were obtained.•A nine-pathogen CIRD PCR panel assay had identified 139 positives from 740 clinical samples with 60 co-infections;•High-concentration target does not have apparent effect on detecting low-concentration targets;•Detection sensitivity were similar between nasal swab and lung tissue samples.

Digital Microfluidic Multiplex RT-qPCR for SARS-CoV-2 Detection and Variants Discrimination.

Continuous mutations have occurred in the genome of the SARS-CoV-2 virus since the onset of the COVID-19 pandemic. The increased transmissibility of the mutated viruses has not only imposed medical burdens but also prolonged the duration of the pandemic. A point-of-care (POC) platform that provides multitarget detection will help to track and reduce disease transmissions. Here we detected and discriminated three genotypes of SARS-CoV-2, including the wildtype and two variants of concern (VOCs), the Delta variant and Omicron variant, through reverse transcription quantitative polymerase chain reaction (RT-qPCR) on a digital microfluidics (DMF)-based cartridge. Upon evaluating with the RNA samples of Omicron variant, the DMF RT-qPCR presented a sensitivity of 10 copies/µL and an amplification efficiency of 96.1%, capable for clinical diagnosis. When spiking with SARS-CoV-2 RNA (wildtype, Delta variant, or Omicron variant) and 18S rDNA, the clinical analog samples demonstrated accurate detection and discrimination of different SARS-CoV-2 strains in 49 min.

Impacts of electronic device use on adolescents' sexual knowledge, attitude and perception during the COVID-19 pandemic: A representative sexuality survey.

Background: COVID-19 pandemic has led to school closure and social distancing measures for infection control. Many young people thus spent more time on electronic devices and the Internet. This study aimed to determine if and how sexual knowledge, perception and behavior as well as sexuality among Hong Kong adolescents were affected as a result. Methods: Youth Sexuality Study conducted by The Family Planning Association of Hong Kong (FPAHK) evaluated the sexual knowledge, attitudes and behaviors and sexual health of youth every 5 years since 1981 with adaptations made to the changing environment. We analyzed this cross-sectional data on sexual knowledge, attitude, and experiences as well as the impacts of COVID-19 on daily life, health and relationships. Univariate analysis was conducted to investigate the relationships between the time spent on electronic devices and sexuality, while mediation analyses using the PROCESS procedure were performed to further explore differences in time spent on electronic devices. Results: During the COVID-19 pandemic, the majority of our participants spent more time on social media and browsing the Internet on electronic devices with less time for extracurricular activities and learning. Nonetheless, there was better overall sexual knowledge and a lower degree of sexual stigma with a higher overall acceptance of sexual minorities. The mediation analyses found that sexual content [Conditional effect = 0.024 (95% CI 0.008, 0.043)] and engagement online [Conditional effect = 0.036 (CI 0.021, 0.053)] could indirectly influence the effect of screen time on the frequency of sexual practices. Conclusion: Policymakers and frontline professionals should re-examine the pedagogy of the present sex education and consider online sex education as the key mode of delivery while guiding the proper use of electronic devices in the learning and exploration of sexual knowledge.

Young Adults' Perspectives on the Implications of an Augmented Reality Mobile Game for Communities' Public Health: A Qualitative Study.

Objectives: Several physical, psychological, and social health consequences are caused by smartphone users' addiction to games. A location-based game (LBG), Pokémon GO, recently garnered significant attention from young people. This study aims to explore their experiences with this game and motivations for playing, investigating their perspectives on the game's implications for themselves and the public health of their communities. Methods: Ten qualitative focus group interviews were conducted. Young adults, aged 18-25 years (n = 60), were recruited in Hong Kong. Data were analyzed using a thematic approach. Results: Five themes emerged: 1) missing out or self-regulation, 2) childhood memories of Pokémon, 3) extending virtual-reality exploration, 4) spending more time outdoors walking and exercising, and 5) getting together with others and social interaction. Conclusions: This study showcases the motivational factors of young adults and their cohorts in societies worldwide. LBGs may impact players' physical and social activity levels, and behavior. Nonetheless, certain negatives were identified (i.e., addiction and behavior resulting from a loss of self-control). These negatives deserve health practitioners' attention and future studies should explore possible public health interventions.

Thoughts and experiences regarding leg amputation among patients with diabetic foot ulcers: A phenomenological study.

Despite lower-limb amputation being common among patients with diabetic foot ulcers, few studies have qualitatively investigated the patients' perspectives. Therefore, this study aimed to explore the thoughts and experiences of patients with diabetic foot ulcers regarding lower-limb amputation in Hong Kong. A phenomenological study using individual, semi-structured interviews was conducted with 18 participants with foot ulcers recruited in Hong Kong between July and September 2022. The interviews were audio-recorded, transcribed verbatim, and analysed using an interpretative phenomenological approach and a constant comparison strategy. The results highlighted four substantial themes: (a) coping or being alone and taciturn, (b) altered appearance impacting one's sense of maintaining social relations, (c) thoughts about self-efficacy and encountering a new normal, and (d) the possibility of a reduced gap in physical consequences between the old and new self. This study provided different perspectives of patients with a history of diabetic foot ulcers, even in cases where lower-limb amputation has not yet been performed. The results demonstrate that lower-limb amputation is considered a forbidden topic. This makes it culturally difficult for Chinese patients to discuss the matter with healthcare authorities and family members. Healthcare workers should be aware of how they communicate regarding lower-limb amputation.

Heartbreak and Loneliness Due to Family Separations and Limited Visiting during COVID-19: A Qualitative Study.

The COVID-19 pandemic has greatly impacted the healthcare system. In the pediatric unit, stress, uncertainty, and many unexpected challenges for many parents were frequently reported. Research has shown that parents had less contact with their children during the pandemic due to hospital restrictions. However, it is unknown how parents perceived their experiences in a pediatric unit. This study aimed to describe the lived experiences of parents who had a child in the pediatric unit during the pandemic. A qualitative descriptive approach was used to investigate parents' experiences of having children admitted to the pediatric unit during the pandemic in Hong Kong. Eight Chinese parents participated in the interview. Three major themes emerged: (1) parents' pediatric ward experiences during COVID-19 were emotionally isolating and overwhelming, (2) the family and family-centered care were disrupted, and (3) interactions with pediatric providers intensified or alleviated emotional distress. Integrating the above themes of experiences of emotional distress was the main characteristic of the parents' experiences during the pandemic. Therefore, policymakers should understand the lived experiences of parents of children diagnosed with COVID-19 and should make prompt decisions to deal with both parental concerns and safety issues.

Escape from cell-cell and cell-matrix adhesion dependence underscores disease progression in gastric cancer organoid models.

OBJECTIVE: Cell-cell (CC) and cell-matrix (CM) adhesions are essential for epithelial cell survival, yet dissociation-induced apoptosis is frequently circumvented in malignant cells. DESIGN: We explored CC and CM dependence in 58 gastric cancer (GC) organoids by withdrawing either ROCK inhibitor, matrix or both to evaluate their tumorigenic potential in terms of apoptosis resistance, correlation with oncogenic driver mutations and clinical behaviour. We performed mechanistic studies to determine the role of diffuse-type GC drivers: ARHGAP fusions, RHOA and CDH1, in modulating CC (CCi) or CM (CMi) adhesion independence. RESULTS: 97% of the tumour organoids were CMi, 66% were CCi and 52% were resistant to double withdrawal (CCi/CMi), while normal organoids were neither CMi nor CCi. Clinically, the CCi/CMi phenotype was associated with an infiltrative tumour edge and advanced tumour stage. Moreover, the CCi/CMi transcriptome signature was associated with poor patient survival when applied to three public GC datasets. CCi/CMi and CCi phenotypes were enriched in diffuse-type GC organoids, especially in those with oncogenic driver perturbation of RHO signalling via RHOA mutation or ARHGAP fusions. Inducible knockout of ARHGAP fusions in CCi/CMi tumour organoids led to resensitisation to CC/CM dissociation-induced apoptosis, upregulation of focal adhesion and tight junction genes, partial reversion to a more normal cystic phenotype and inhibited xenograft formation. Normal gastric organoids engineered with CDH1 or RHOA mutations became CMi or CCi, respectively. CONCLUSIONS: The CCi/CMi phenotype has a critical role in malignant transformation and tumour progression, offering new mechanistic information on RHO-ROCK pathway inhibition that contributes to GC pathogenicity.

Effect of a Novel E3 Probiotics Formula on the Gut Microbiome in Atopic Dermatitis Patients: A Pilot Study.

Atopic dermatitis (AD) has been shown to be closely related to gut dysbiosis mediated through the gut−skin axis, and thus the gut microbiome has recently been explored as a potential therapeutic target for the treatment of AD. Contrasting and varying efficacy have been reported since then. In order to investigate the determining factor of probiotics responsiveness in individuals with AD, we initiated the analysis of 41 AD patients with varying disease severity in Hong Kong, whereas the severity was assessed by Eczema Area and Severity Index (EASI) by board certified dermatologist. 16S rRNA sequencing on the fecal samples from AD patients were performed to obtain the metagenomics profile at baseline and after 8 weeks of oral administration of a novel E3 probiotics formula (including prebiotics, probiotics and postbiotics). While EASI of the participants were significantly lower after the probiotics treatment (p < 0.001, paired Wilcoxon signed rank), subjects with mild AD were found to be more likely to respond to the probiotics treatment. Species richness among responders regardless of disease severity were significantly increased (p < 0.001, paired Wilcoxon signed rank). Responders exhibited (1) elevated relative abundance of Clostridium, Fecalibacterium, Lactobacillus, Romboutsia, and Streptococcus, (2) reduced relative abundance of Collinsella, Bifidobacterium, Fusicatenibacter, and Escherichia-Shigella amid orally-intake probiotics identified using the machine learning algorithm and (3) gut microbiome composition and structure resembling healthy subjects after probiotics treatment. Here, we presented the gut microbiome dynamics in AD patients after the administration of the E3 probiotics formula and delineated the unique gut microbiome signatures in individuals with AD who were responding to the probiotics. These findings could guide the future development of probiotics use for AD management.

The Lived Experiences of Women without COVID-19 in Breastfeeding Their Infants during the Pandemic: A Descriptive Phenomenological Study.

The coronavirus disease 2019 (COVID-19) outbreak in 2020 has led to several changes and disturbances in the daily lives of the general public. Particularly for new (first-time) mothers, there has been a significant impact on the practices of raising and feeding their babies. Social distancing measures everywhere have made mothers hesitant to breastfeed their babies anywhere else but at home. Combined with the fear of being infected with COVID-19, the present situation has created unprecedented barriers for breastfeeding mothers to accessing various types of support: emotional, instrumental, informational, and appraisal. There has been no research on the influence of the pandemic on social support regarding breastfeeding in Hong Kong. This study aimed to explore the social support and impact of COVID-19 on mothers breastfeeding their babies. Semi-structured interviews were conducted with 20 currently breastfeeding women in Hong Kong. Colaizzi's seven-step method was used for data analysis. Two key themes emerged from the interview data: (1) positive influences on breastfeeding support during COVID-19 and (2) negative influences on breastfeeding support during COVID-19. Our findings may help mothers prepare to breastfeed their babies in places other than their homes.

Psychological Experiences of Patients with Coronavirus Disease 2019 (COVID-19) during and after Hospitalization: A Descriptive Phenomenological Study.

During an infectious disease pandemic, patients may experience various psychological issues. Few studies have focused on survivors' experiences in Hong Kong. This study aimed to assess the psychological impacts of coronavirus disease 2019 (COVID-19) on survivors during admission to and discharge from COVID-19 wards using a descriptive phenomenological design. Purposive sampling was used to recruit 20 participants aged 30-77 years recently discharged from an isolation ward at an acute care facility and transferred to a community center specializing in pulmonary rehabilitation. Sampling was performed from 1 March 2022 to 3 April 2022. Semi-structured in-person interviews were conducted and transcribed verbatim; data analysis was performed using Colaizzi's approach. The patients experienced two exclusive psychological phases during and after admission. The analysis of the patients' experiences revealed three themes: (i) navigating uncertainties with mixed feelings and emotions during admission, (ii) adjusting to normal daily life after discharge, and (iii) self-growth after discharge. Our findings may provide empirical evidence for formulating pre-emptive strategies to mitigate the long-term psychological impacts of COVID-19. This investigation is timely and internationally relevant, and policymakers can use these findings to make informed decisions when developing guidelines for structuring the care of patients with COVID-19 during and after hospitalization. Based on our findings, we recommended that psychological support, particularly the provision of time to address patients' concerns, may be integrated into the care of patients with COVID-19. Additionally, the structure of care may extend beyond the biomedical aspects of the illness to encompass the emotional and social dimension of the patients. To reduce stigmatization, we advise that public health authorities release clear information timely to clarify the misconceptions of the local community.

When rationing becomes inevitable in a pandemic: A discussion on the ethical considerations from a public health perspective.

Objectives: Coronavirus Disease 2019 has presented extreme difficulties to healthcare resource allocation worldwide. Health resources, particularly during a pandemic, are limited even in developed countries. The main challenge for healthcare professionals is to be able to ration resources in an ethical manner. Therefore, this leads to ethical considerations that we aim to discuss in this paper, based on which, recommendations can be made for reference by healthcare management, policymakers, and public health practitioners. Study design: This is a discussion paper. Methods: A brief review of the major principles as they relate to the notion of rationing in a pandemic was conducted. We organized an ethical discussion from public health perspectives based on these major principles. Results: Prior to deciding the principles to adopt, a transparent and robust guideline for rationing must be established. There are four considerations that need to be made: transparency, consistency, inclusiveness, and accountability. There does not exist a "perfect" principle to adopt during rationing. However, in the authors' opinion, the most obvious principles that would be unsuitable during a healthcare crisis would be the equal worth and prioritarian principles. This leaves the equity principle, utilitarian and urgent need principles. Conclusion: The recommendation of this discussion paper is to adopt multiple principles according to the situation of each country or even the particular hospital.

Development of a three-panel multiplex real-time PCR assay for simultaneous detection of nine canine respiratory pathogens.

Infectious respiratory disease is one of the most common diseases in dogs worldwide. Several bacterial and viral pathogens can serve as causative agents of canine infectious respiratory disease (CIRD), including Mycoplasma cynos, Mycoplasma canis, Bordetella bronchiseptica, canine adenovirus type 2 (CAdV-2), canine herpesvirus 1 (CHV-1), canine parainfluenza virus (CPIV), canine distemper virus (CDV), canine influenza virus (CIA) and canine respiratory coronavirus (CRCoV). Since these organisms cause similar clinical symptoms, disease diagnosis based on symptoms alone can be difficult. Therefore, a quick and accurate test is necessary to rapidly identify the presence and relative concentrations of causative CIRD agents. In this study, a multiplex real-time PCR panel assay was developed and composed of three subpanels for detection of the aforementioned pathogens. Correlation coefficients (R2) were >0.993 for all singleplex and multiplex real-time PCR assays with the exception of one that was 0.988; PCR amplification efficiencies (E) were between 92.1% and 107.8% for plasmid DNA, and 90.6-103.9% for RNA templates. In comparing singular and multiplex PCR assays, the three multiplex reactions generated similar R2 and E values to those by corresponding singular reactions, suggesting that multiplexing did not interfere with the detection sensitivities. The limit of detection (LOD) of the multiplex real-time PCR for DNA templates was 5, 2, 3, 1, 1, 1, 4, 24 and 10 copies per microliter for M. cynos, M. canis, B. brochiseptica, CAdV-2, CHV-1, CPIV, CDV, CIA and CRCoV, respectively; and 3, 2, 6, 17, 4 and 8 copies per microliter for CAdV-2, CHV-1, CPIV, CDV, CIA and CRCoV, respectively, when RNA templates were used for the four RNA viruses. No cross-detection was observed among the nine pathogens. For the 740 clinical samples tested, the newly designed PCR assay showed higher diagnostic sensitivity compared to an older panel assay; pathogen identities from selected samples positive by the new assay but undetected by the older assay were confirmed by Sanger sequencing. Our data showed that the new assay has higher diagnostic sensitivity while maintaining the assay's specificity, as compared to the older version of the panel assay.

Mutational landscape of normal epithelial cells in Lynch Syndrome patients.

Lynch Syndrome (LS) is an autosomal dominant disease conferring a high risk of colorectal cancer due to germline heterozygous mutations in a DNA mismatch repair (MMR) gene. Although cancers in LS patients show elevated somatic mutation burdens, information on mutation rates in normal tissues and understanding of the trajectory from normal to cancer cell is limited. Here we whole genome sequence 152 crypts from normal and neoplastic epithelial tissues from 10 LS patients. In normal tissues the repertoire of mutational processes and mutation rates is similar to that found in wild type individuals. A morphologically normal colonic crypt with an increased mutation burden and MMR deficiency-associated mutational signatures is identified, which may represent a very early stage of LS pathogenesis. Phylogenetic trees of tumour crypts indicate that the most recent ancestor cell of each tumour is already MMR deficient and has experienced multiple cycles of clonal evolution. This study demonstrates the genomic stability of epithelial cells with heterozygous germline MMR gene mutations and highlights important differences in the pathogenesis of LS from other colorectal cancer predisposition syndromes.

Molecular detection of SARS-CoV-2 and differentiation of Omicron and Delta variant strains.

The SARS-CoV-2 virus is the causative agent of COVID-19 and has undergone continuous mutations throughout the pandemic. The more transmissible Omicron variant has quickly spread and is replacing the Delta variant as the most prevalent strain globally, including in the United States. A new molecular assay that can detect and differentiate both the Delta and Omicron variants was developed. A collection of 660,035 SARS-CoV-2 full- or near-full genomes, including 169,454 Delta variant and 24,202 Omicron variant strains, were used for primer and probe designs. In silico data analysis predicted an assay coverage of >99% of all strains, including >99% of the Delta and >99% of Omicron strains. The Omicron variant differential test was designed based on the Δ31-33 aa deletion in the N-gene, which is present in the original B.1.1.529 main genotype, BA.1, as well as in BA.2 and BA.3 subtypes. Therefore, the assay should detect the majority of all Omicron variant strains. Standard curves generated with human clinical samples indicated that the PCR amplification efficiencies were 104%, 90.7% and 90.4% for the Omicron, Delta, and non-Delta/non-Omicron wild-type genotypes, respectively. Correlation coefficients of the standard curves were all >0.99. The detection limit of the assay was 14.3, 32.0, and 21.5 copies per PCR reaction for Omicron, Delta, and wild-type genotypes, respectively. The assay was designed to specifically detect SAR-CoV-2 strains. Selected samples with Omicron, Delta and wild-type genotypes identified by the RT-qPCR assay were also confirmed by sequencing. The assay did not detect any animal coronavirus-positive samples that were tested. Human nasal swab samples that previously tested positive (n = 182) or negative (n = 42) for SARS-CoV-2 by the ThermoFisher TaqPath COVID-19 Combo Kit, produced the same result with the new assay. Among positive samples, 55.5% (101/182), 23.1% (42/182), and 21.4% (39/182) were identified as Omicron, Delta, and non-Omicron/non-Delta wild-type genotypes, respectively.

Development of a real-time PCR assay for detection and differentiation of Mycoplasma ovipneumoniae and a novel respiratory-associated Mycoplasma species in domestic sheep and goats.

A novel respiratory-associated Mycoplasma species (M. sp. nov.) of unknown clinical significance was recently identified that causes false positive results with multiple published PCR methods reported to specifically detect Mycoplasma ovipneumonaie, a well-known respiratory pathogen in small ruminants. This necessitates our objective to develop a real-time PCR (qPCR) assay for improved specificity and sensitivity, and more rapid detection and differentiation of M. ovipneumoniae and the M. sp. nov. in domestic sheep (DS) and domestic goat (DG) samples, as compared to a conventional PCR and sequencing (cPCR-seq) assay. Primers and probes were designed based on available M. ovipneumoniae 16S rRNA gene sequences in the GenBank database, and partial 16S rRNA gene sequences provided by the United States Department of Agriculture, Agricultural Research Service (USDA-ARS) for M. ovipneumoniae and M. sp. nov. USDA-ARS provided DS (n = 153) and DG (n = 194) nasal swab nucleic acid that previously tested positive for either M. ovipneumoniae (n = 117) or M. sp. nov. (n = 138), or negative for both targets (n = 92) by cPCR-seq. A host 18S rRNA gene was included as an internal control to monitor for the failure of nucleic acid extraction and possible PCR inhibition. For samples positive by cPCR-seq, qPCR agreement was 88.0% (103/117; κ = 0.81) and 89.9% (124/138; κ = 0.84) for M. ovipneumoniae and M. sp. nov., respectively; 12 of 255 (4.7%) cPCR-seq positive samples were qPCR positive for both targets. Of samples negative by cPCR for both mycoplasmas, qPCR detected M. ovipneumoniae and M. sp. nov. in 6.5% (6/92) and 4.3% (4/92), respectively. Samples with discordant results between the cPCR and sequencing assay and the new qPCR were analyzed by target sequencing; successfully sequenced samples had identity matches that confirmed the qPCR result. The increased target specificity of this qPCR is predicted to increase testing accuracy as compared to other published assays.

Molecular detection of SARS-CoV-2 strains and differentiation of Delta variant strains.

The Delta variant of SARS-CoV-2 has now become the predominant strain in the global COVID-19 pandemic. Strain coverage of some detection assays developed during the early pandemic stages has declined due to periodic mutations in the viral genome. We have developed a real-time RT-PCR (RT-qPCR) for SARS-CoV-2 detection that provides nearly 100% strain coverage, and differentiation of highly transmissible Delta variant strains. All full or nearly full (≥28 kb) SARS-CoV-2 genomes (n = 403,812), including 6422 Delta and 280 Omicron variant strains, were collected from public databases at the time of analysis and used for assay design. The two amino acid deletions in the spike gene (S-gene, Δ156-157) that is characteristic of the Delta variant were targeted during the assay design. Although strain coverage for the Delta variant was very high (99.7%), detection coverage for non-Delta wild-type strains was 93.9%, mainly due to the confined region of design. To increase strain coverage of the assay, the design for CDC N1 target was added to the assay. In silico analysis of 403,812 genomes indicated a 95.4% strain coverage for the CDC N1 target, however, in combination with our new non-Delta S-gene target, total coverage for non-Delta wild-type strains increased to 99.8%. A human 18S rRNA gene was also analyzed and used as an internal control. The final four-plex RT-qPCR assay generated PCR amplification efficiencies between 95.4% and 102.0% with correlation coefficients (R2 ) of >0.99 for cloned positive controls; Delta and non-Delta human clinical samples generated PCR efficiencies of 93.4%-97.0% and R2  > 0.99. The assay also detects 98.6% of 280 Omicron sequences. Assay primers and probes have no match to other closely related human coronaviruses, and did not produce a signal from samples positive to selected animal coronaviruses. Genotypes of selected clinical samples identified by the RT-qPCR were confirmed by Sanger sequencing.

Exploring the Gender-Related Perceptions of Male Nursing Students in Clinical Placement in the Asian Context: A Qualitative Study.

The lack of gender diversity in the nursing profession has long been recognized as a cause for concern. Female nurses in many practice settings across nations continue to outnumber their male counterparts. Male nursing students may have perceived differences in the way they are treated in clinical practice; however, limited studies have been conducted to determine the unique perspectives of these students in terms of gender bias in their clinical learning. To address this knowledge gap, this study employed a qualitative descriptive approach to explore the experiences of male nursing students in clinical learning in an Asian context. Specifically, we examined the insights emerging from the thoughts and feelings of male nursing students from interactions with their clinical mentors, patients, and peers in their encounters during their clinical placement. From November 2019 to July 2020, data were collected through semi-structured interviews from 22 male participants aged 21-30 years (mean age: 22.7), enrolled in a prelicensure Bachelor of Nursing (honors) program in Hong Kong. Four themes emerged after a qualitative content analysis: (1) while the School of Nursing welcomes men, clinical settings are another story due to pragmatic considerations; (2) you are welcomed because you may be seen as a helper with greater physical strength; (3) male nursing students feel alienated in the obstetrics and gynecology practicum; (4) more male role models are desired in the clinical setting. Our findings indicate the need to promote gender awareness among faculty and clinical mentors, understand the factors hindering and facilitating the clinical practicum for male nursing students, improve the male nursing experience during the maternity practicum, and ensure access to more male role models to boost role socialization and learning.

The Transformational Experience of Junior Nurses Resulting from Providing Care to COVID-19 Patients: From Facing Hurdles to Achieving Psychological Growth.

The rapid spread of coronavirus disease 2019 (COVID-19) has put significant pressure on junior nursing staff. The objective of this study was to examine the in-depth experiences of junior nurses in providing care for COVID-19 patients within an acute care setting. This study employed a phenomenological method to understand the situation from a first-person perspective. Purposive sampling was used. Interviews were performed with 40 junior nurses (<4 years of clinical experience) who provided direct care to COVID-19 patients in isolation wards in acute care settings in Hong Kong. The interviews were conducted from 1 January 2021 to 24 May 2021 via virtual conferencing software (Zoom) to maintain social distancing, and the responses were analysed using Colaizzi's seven-step method. Junior nurses' psychological experiences of providing direct care to COVID-19 patients were categorised into four main themes. First, there were hurdles in the early stages, in which participants experienced negative emotions, such as fear, anxiety, helplessness, and fatigue. Somatic symptoms, such as headaches and sleep disturbance, were reported. Second, the adoption of self-care coping strategies enabled nurses to confront the hurdles, signifying the start of self-transformation. Third, junior nurses maintained positivity under pressure by appreciating their sources of support (including their families and other important relationships in their lives). Professionalism was also found to reinforce positivity. Fourth, self-transformation resulted in psychological growth, which prepared junior nurses to be resilient and confident in their clinical practice to take up future challenges in the ongoing battle against the pandemic. The hurdles experienced by junior nurses at the early stage of their work in isolation wards provided the foundation upon which self-transformation took place. Being able to employ self-care coping strategies and further sustain positivity characterised the self-transformation process. Eventually, junior nurses became resilient and more capable of understanding both the negativity and positivity of their experiences. The self-transformation process also enabled junior nurses to recognise and appreciate the wider support system from various parties in society.

Empathic accuracy of young boys and girls in ongoing parent-child interactions: Performance and (mis)perception.

Understanding others accurately is crucial in relationships and learning. Research shows that adults face challenges in empathic accuracy, that is, the ability to read the content of others' moment-to-moment mental states during interactions. Although young children possess some empathic understanding, the extent of their empathic accuracy is uncharted. Using a new SSP, 106 Chinese children aged 60 to 80 months (M = 70 months) were assessed on their ability to infer the mental states of adults in ongoing parent-child interactions. Replicating and extending extant findings on adults and adolescents, the children's inferences were found to be, at least computationally on a scale of .00 to 1.00, more often inaccurate than accurate regardless of the gender of the targets or participants (overall accuracy rate = .28). However, both the children and their primary caregivers overestimated the children's performance. In addition, although the primary caregivers expected girls to outperform boys, no gender difference in empathic accuracy was found when controlling for verbal fluency. Drawing on the findings of this first-ever application of the empathic accuracy paradigm in young children, the implications of empathic accuracy performance and misperceptions about such accuracy are discussed.
