Potent Anti-SARS-CoV-2 Efficacy of COVID-19 Hyperimmune Globulin from Vaccine-Immunized Plasma.

Coronavirus disease 2019 (COVID-19) remains a global public health threat. Hence, more effective and specific antivirals are urgently needed. Here, COVID-19 hyperimmune globulin (COVID-HIG), a passive immunotherapy, is prepared from the plasma of healthy donors vaccinated with BBIBP-CorV (Sinopharm COVID-19 vaccine). COVID-HIG shows high-affinity binding to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein, the receptor-binding domain (RBD), the N-terminal domain of the S protein, and the nucleocapsid protein; and blocks RBD binding to human angiotensin-converting enzyme 2 (hACE2). Pseudotyped and authentic virus-based assays show that COVID-HIG displays broad-spectrum neutralization effects on a wide variety of SARS-CoV-2 variants, including D614G, Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1), Kappa (B.1.617.1), Delta (B.1.617.2), and Omicron (B.1.1.529) in vitro. However, a significant reduction in the neutralization titer is detected against Beta, Delta, and Omicron variants. Additionally, assessments of the prophylactic and treatment efficacy of COVID-HIG in an Adv5-hACE2-transduced IFNAR-/- mouse model of SARS-CoV-2 infection show significantly reduced weight loss, lung viral loads, and lung pathological injury. Moreover, COVID-HIG exhibits neutralization potency similar to that of anti-SARS-CoV-2 hyperimmune globulin from pooled convalescent plasma. Overall, the results demonstrate the potential of COVID-HIG against SARS-CoV-2 infection and provide reference for subsequent clinical trials.

Experiences of Women Who Refuse Recall for Further Investigation of Abnormal Screening Mammography: A Qualitative Study.

Breast cancer has the highest incidence among all cancers for women in Taiwan. The current screening policy in Taiwan provides biennial mammogram tests for all women aged 45 to 69 years. A recommendation for further investigation is sent via post to women with a BI-RADS result of 0. The proportion of women who followed-up with a recall request for further investigation after an abnormal mammogram has been below 92.5% in recent years. Therefore, we aimed to explore the experiences of these women who refused recall for further investigation despite an abnormal mammogram. Purposive sampling was conducted on 13 women who refused recall for further examination of abnormal screening mammograms. Data collection included inductive, in-depth interviews or telephone interviews. A content analysis was applied. Three themes were identified: (1) negative screening experiences, (2) struggling with 'to go or not to go', and (3) rationalizing without a follow-up examination. The first theme included three subthemes: (1) pain of examination, (2) the inconvenience of medical treatment; waiting, and (3) dissatisfaction with having to pay for further examination. The second major theme included three subthemes: (1) perceiving one's susceptibility to breast cancer as very low, (2) questioning the accuracy of the results, and (3) procrastinating with a "head-in-the-sand" mentality. The third major theme included two subthemes: (1) fatalism and (2) paying attention to self-cultivation. In conclusion, the findings provide important information to healthcare providers involved in case management related to the actual living experiences of women with abnormal screening mammogram results and the additional education required to raise breast cancer awareness in the general public to achieve overall caring goals.

Teenagers Who Coexist With Cancer: Chemotherapy Body and Self-integration.

BACKGROUND: The experiences of teenagers with cancer are related to falling ill, receiving treatment, and the way they exist in the world. The understanding of the meaning of teenagers coexisting with cancer must be placed in the social context with the teenagers at the core. OBJECTIVE: By using an interpretive ethnographic research method, this study applied the body perception view of Merleau-Ponty to how teenagers with cancer understand self through the body in a social and cultural context. METHODS: Participant observation and individual semistructured interviews of 18 teenagers diagnosed with cancer were conducted over a 20-month period. RESULTS: The illness experience of teenagers undergoing chemotherapy was described as self-integration. Five themes emerged: boundary ambiguity of body, medical equipment as part of the body, confined body space, from self-dissociation toward self-integration, and healing power formed by self and others. CONCLUSION: In the face of the adjustments of body disorder, the teenagers with cancer initiated motility of the body, self-displacement, and integration in order to regain control of the body. IMPLICATIONS FOR PRACTICE: The provision of correct disease knowledge to strengthen teenagers' understanding and their sense of mastery of their bodies throughout the participation in their cancer treatment is essential. Discussions on making decisions, self-management, and social identification are related to the relationship between body and self as well as between healthcare and otherness. Providing culture and social sensitivity support systems and resources to teenagers and families can strengthen them to face the disease and promote positive healing.

Experiences of parents providing kangaroo care to a premature infant: A qualitative systematic review.

Parents who give birth to an unexpected preterm infant not only suffer a psychological impact, but, in addition, their roles as parent are full of uncertainty. As part of family-centered care, kangaroo care is an important way to support premature infants and their family. This review synthesizes qualitative studies on the experiences of parents who have used kangaroo care for preterm infants in neonatal intensive care units. English and Chinese databases were searched for relevant studies from 1970 to July 2018. The findings of qualitative studies were extracted and pooled using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. A total of 731 studies were screened, and 9 were included. Five synthesized findings were identified: sense of emptiness of the parent's role, barriers in the translation of parental roles in kangaroo care, preparation enhances parental role expectations, kangaroo care enhances parental competency, and encouragement and support from family and friends. Through the implementation of kangaroo care, nurses are able to help prepare and guide parents, fit parents' needs, and help improve their ability and self-confidence in their parental roles.

A Systematic Review of the Experiences of Siblings of Children With Cancer.

BACKGROUND: When there is a child with cancer in the family, the entire family is affected. Childhood cancer is a highly stressful experience that affects the adaptation of family member to psychosocial tasks. Many of the family stresses and changes that accompany childhood cancer have a severe impact on siblings. An understanding of the experiences and needs of such siblings is vital. OBJECTIVE: The aim of this study was to understand the nature of the overall experiences of a child who has a brother or sister with cancer. METHODS: Searches of CINAHL, MEDLINE/PubMed, Science Direct, Scopus, Eric, and Chinese electronic periodical services identified 10 qualitative studies that were published between 1960 and 2013. An appraisal of the primary studies was carried out using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. RESULTS: Siblings of children with cancer were found to have experienced 4 themes: (1) the disintegration of life, (2) marginalization within their family relationships, (3) self-transcendence during the normalization of family relationships, and (4) maintenance of family integrity and family normality. CONCLUSIONS: Siblings of children with cancer experience a great deal of chaos in their family life, and this affects their self-esteem and family intimacy. Being with the sick child may help siblings understand the sick child's suffering and experiences. IMPLICATIONS FOR PRACTICE: The findings of this review provide evidence to help health professionals to assess the needs of the siblings to enhance their sense of self within the family. Providing the siblings with suitable resources should result in better adjustment.

Lived experience of epilepsy from the perspective of children in Taiwan.

AIMS: The purpose of this study was to explore the lived experiences of school-aged children with epilepsy in Taiwan. BACKGROUND: Epilepsy affects many people worldwide, especially school-aged children, but few studies have examined children's viewpoints of their experiences with epilepsy. DESIGN: An exploratory, phenomenological interview design was used. METHODS: Children (ages 7-12 years) with well-controlled epilepsy and no developmental delay were recruited from a hospital in central Taiwan. Data were collected from 15 children using a semi-structured interview guide. Interviews were tape-recorded with permission from parents and children. Verbatim transcripts were analysed using Colazzi's phenomenological method. RESULTS: Two themes emerged from the analysis. The first theme, 'living with epilepsy', had two subthemes: disease-related experiences and school-related issues. The second theme, 'coping with epilepsy', had two subthemes: developing strategies to manage or reduce seizures and seeking support from family members. CONCLUSIONS: Taiwanese children with epilepsy had similar lived experiences as their counterparts in Western culture, e.g. unpleasant somatic symptoms, difficulty learning and troubled peer relationships. Taiwanese children also coped similarly with epilepsy by taking medications to control seizures, but they differed from their Western counterparts in trying to self-manage seizures and seeking support from family members. RELEVANCE TO CLINICAL PRACTICE: Public health and school nurses can apply our findings to educate school teachers and parents about epilepsy and encourage activities that allow children with and without epilepsy to interact, thus improving peer relationships and reducing stigmatisation. Children with and without epilepsy would also benefit from an age-appropriate education manual that includes causes of epilepsy, treatment, dealing with seizures and psychological and social adaptation.

Cinnamylphenols from Phyllodium pulchellum.

Four new cinnamylphenols, pulchelstyrenes A (1), B (2), C (3), and D (4), together with citrusinol, yukovanol, methyl piperitol, and 4-hydroxy-2,3-dimethoxybenzaldehyde were isolated from the aerial part of Phyllodium pulchellum. The structures of these compounds were determined by spectroscopic methods. Compounds 2, 3, and citrusinol exhibited marginal cytotoxicity against KB cells, and citrusinol also showed mild cytotoxicity against the HepG2 cell line.
