Design of online formative assessment of nursing humanities curriculum during the COVID-19 pandemic: A teaching practice research.

BACKGROUND: Under the digital transformation trend nursing education, online formative assessment (OFA) provides a new opportunity. However, the OFA of nursing humanities course lacks design and practice, and faces the challenge of enhancing effective communication between teachers and students, student participation and autonomous learning. OBJECTIVES: To enhance the reliability of OFA in nursing humanities courses and provide practical experience for online teaching in the nursing profession. DESIGN: A quantitative research approach was used. SETTING: This study was conducted in a comprehensive university in China. PARTICIPANTS: We conducted teaching practice on 185 nursing undergraduates, with 89 students in the experimental group, and 96 students in the control group. METHODS: In the 2020-2021 multicultural nursing course, student learning outcomes and questionnaires were analyzed through the online learning tool Superstar Learning, student feedback and satisfaction questionnaires, and descriptive analysis and independent sample t-tests were conducted using SPSS 25.0 software. RESULTS: The OFA of students using Superstar Learning differed in learning performance and time to receive feedback from teachers between the experimental and control groups, and both groups had higher satisfaction levels. The experimental group's instructional design contained a synchronous classroom discussion module with better participation. CONCLUSIONS: During the COVID-19 pandemic, the use of online learning tools can support the implementation of OFA, build an environment where teachers and students participate together, have a positive impact on the continuous updating of teachers' teaching programs and students' learning outcomes. Simultaneous classroom discussions are expected to be an effective way to improve the reliability of OFA. Our instructional design, provides best practice suggestions for future online teaching and learning.

Screening of sperm antigen epitopes by phage display technique and its preliminary clinical application.

BACKGROUND: At present, there is a lack of standardized preparation methods of sperm antigen for the detection of antisperm antibody (AsAb). To screen sperm antigen mimotopes from a phage display random peptide library and use them to establish an enzyme-linked immunosorbent assay (ELISA) for the detection of AsAb, immunoglobulins were extracted from the sera of rabbits with positive AsAb and negative AsAb, respectively, by the saturated ammonium sulfate method, and a phage display 12-mer peptide library was affinity panned by the extracted immunoglobins coated on the ELISA plate. Then, the obtained positive phage clones were identified by ELISA and sent for sequencing and peptides synthesis. Last, a diagnostic ELISA was established to detect clinical serum and seminal plasma samples. RESULTS: A total of sixty phage clones were chosen by affinity panning, and sixteen of them reacted positively with AsAb in indirect ELISA and sandwich ELISA. Following DNA sequencing and translation, the peptide sequences of the sixteen positive clones were obtained. By comparison in Blast database, four of sixteen positive clones were found to be closely related to male reproduction. Two (#1 and #25) of four mimotopes were synthesized, and an ELISA method was established using the two mimotopes as sperm specific antigens. One hundred and thirty-four serum samples and seventy-four seminal plasma samples from infertile couples were analyzed by the established ELISA with #1 and #25 mimotopes, respectively. The positive rates of AsAb in serum samples were 20.15% (27/134) for #1 and 11.19% (15/134) for #25, respectively, and the coincidence rate between them was 91.04% (122/134). The positive rates of AsAb in seminal plasma samples were 1.35% (1/74) for both #1 and #25, and the coincidence rate was 100%. CONCLUSION: Sperm antigen mimotopes can be obtained successfully by the phage display technique, and can be used as standard sperm specific antigens to establish an ELISA method for the detection of AsAb.

RéSUMé: CONTEXTE: À ce jour, il n'existe pas de méthodes normalisées de préparation d'antigènes spermatiques pour la détection des anticorps anti-spermatozoïdes (ACAS). Dans le but d'élaborer un tel test ELISA (enzyme-linked immunosorbent assay), nous avons extrait de sérum de lapins des anticorps anti-spermatozoïdes humains via la technique du sulfate d'ammonium saturé et en ayant recours à une librairie phagique de peptides (12-mer). Les clones positifs ont été identifiés par ELISA, séquencés à façon et les peptides correspondants ont été synthétisés. In fine, un test ELISA diagnostic a été conçu pour être utilisé avec des échantillons cliniques de sérum et de plasmas séminaux. RéSULTATS: Au total, soixante clones de phages ont été sélectionnés, et seize d'entre eux se sont avérés interagir avec les ACAS en ELISA indirect comme en ELISA sandwich. Les séquences peptidiques de ces seize clones positifs ont été obtenues. Par comparaison avec les bases de données (Blast), quatre de ces seize clones positifs se sont révélés être étroitement liés à la reproduction masculine. Deux des quatre mimotopes (#1 et #25) ont été synthétisés, et un test ELISA a été généré en utilisant ces deux mimotopes comme antigènes spécifiques des spermatozoïdes. Cent trente-quatre échantillons de sérum et soixante-quatorze échantillons de plasma séminal de patients de couples infertiles ont alors été analysés avec ce test ELISA. Respectivement, les échantillons sériques se sont révélés positifs à 20,15% (27/134) pour le mimotope #1 et à 11,19% (15/134) pour le mimotope #25, avec un taux de coïncidence de 91,04% (122/134). Seul un échantillon de plasma séminal (1/74, soit 1, 35%) s'est révélé positif à la fois pour le mimotope #1 et #25 (coïncidence 100%). CONCLUSION: La technique « phage display¼ nous a permis d'identifier des mimotopes d'antigènes spermatiques qui ont pu être utilisés afin de générer un test ELISA pour la détection d'anticorps anti-spermatozoïdes.

Preferences of oral nutritional supplement therapy among postoperative patients with gastric cancer: Attributes development for a discrete choice experiment.

BACKGROUND: Adherence to oral nutritional supplement therapy among postoperative patients with gastric cancer is low. There is little knowledge about patients' priorities and needs regarding oral nutritional supplement therapy. The discrete choice experiment is an innovative method used to elicit patients' preferences. Good practice guidelines emphasize that the development of attributes and levels is a fundamentally important process. OBJECTIVE: To comprehensively describe the identification, refinement, and selection of attributes and levels for a discrete choice experiment. METHODS: A mixed-methods approach, consisting of three consecutive steps: a literature review, in-depth interviews, and focus groups. First, the literature review allowed quick identification of attributes and levels. Then, 15 in-depth interviews were conducted to gather a rich description of the experience of patients taking oral nutritional supplements after gastrectomy and to verify and enrich the attributes and levels list. Finally, four focus group participants discussed the wording of the attributes and levels and reduced the number of attributes to manageable numbers through voting ranking methods. RESULTS: Following the literature review and qualitative data collection, eight attributes were finally generated, each with two to three levels. The following attributes were included: 1) information provider; 2) health guidance approach; 3) adverse reactions; 4) flavor; 5) follow-up method; 6) follow-up frequency; 7) psychological support; 8) cost. These attributes covered the important attributes of nutritional preparations and health guidance included in ONS therapy that were relevant to patients. CONCLUSIONS: This study's mixed-methods approach has been found highly suitable to identify, refine and select attributes and levels for a discrete choice experiment. The three methods have pros and cons, and they complement each other, especially the analysis of qualitative data led to a deeper and broader understanding of attributes and levels.

The Public's Preferences for Psychological Interventions During the COVID-19 Pandemic: A Discrete Choice Experiment.

Aims: To explore the public's preference for psychological interventions through a discrete choice experiment and to provide references for formulating psychological intervention policies and establishing psychological intervention procedures in response to public health emergencies. Methods: This study is a discrete choice experiment. Attributes and levels were identified through literature reviews, in-depth interviews, focus group discussions, and expert consultations. Experimental design principles were applied to generate choice sets containing different attribute levels and develop a survey instrument. Convenience sampling was conducted nationwide, and 1,045 participants were investigated. A mixed logit model was used to evaluate the public's preferences. Results: All attributes in our study were found to have a significant influence on the public's preferences for psychological interventions during the COVID-19 pandemic. The public's preferences for providers and duration were influenced by the public's levels of education and classifications. Furthermore, the most ideal scenario was found to be a one-on-one psychological intervention provided by family and friends through social network platforms, for which the frequency is twice per week, and the duration of each intervention is 0.5-1 h. Conclusions: The public's preferences for psychological interventions during the COVID-19 pandemic are affected by the method, form, frequency, provider, and duration of interventions. Our findings provide references for the formulation of psychological intervention policies and the establishment of psychological intervention procedures in response to public health emergencies.

Efficacy and safety of short-wave diathermy treatment for moderate COVID-19 patients: a prospective, double-blind, randomized controlled clinical study.

BACKGROUND: Millions of human beings have suffered in the epidemic of Coronavirus disease 2019 (COVID-19), but until now the effective treatment methods have been limited. AIM: This study aimed to evaluate the efficacy and safety of short-wave diathermy (SWD) treatment for moderate COVID-19 patients. DESIGN: A prospective, double-blind, randomized controlled clinical study. SETTING: Inpatients Unit of a COVID-19 specialized hospital. POPULATION: Forty-two patients with moderate COVID-19 were randomly allocated at a 2:1 ratio to two groups: the SWD group and the control group. METHODS: Participants of the SWD group received SWD treatment, and participants of the control group received placebo SWD treatment for one session per day, 10 minutes per session, for no more than 14 days. Both groups were given standard care treatment. Primary outcome was the rate of clinical improvement according to a seven-category ordinal scale. Secondary outcomes included the rate of computed tomography (CT) improvement and the rate of potential adverse events. RESULTS: Clinical improvement occurred in 92.6% of patients in the SWD group by day 14 compared with 69.2% of patients in the control group (P=0.001). The Cox model indicated that the SWD group had a higher clinical improvement probability than the control group (hazard ratio: 3.045; 95% CI: 1.391-6.666; P=0.005). Similarly, CT improvement occurred in 85.2% of patients in the SWD group and 46.2% of patients in the control group respectively by day 14 (P=0.001). The Cox model indicated SWD group had a higher CT improvement probability than control group (hazard ratio: 3.720; 95% CI: 1.486-9.311; P=0.005). There was no significant difference in adverse events between the SWD group and the control group (2 of 27 [7.4%] SWD vs. 1 of 13 [7.7%] control, P=1.000), the most frequent of which were headache (1 of 27 [3.7%] SWD vs. 1 of 13 [7.7%] control patients) and dizziness (1 of 27 [3.7%] SWD vs. 0 of 13 [0%] control patients). CONCLUSIONS: SWD is a valid and reliable adjuvant therapy with a favorable safety profile for moderate COVID-19 patients. CLINICAL REHABILITATION IMPACT: Clinically relevant information is lacking regarding the efficacy and safety of SWD for patients with COVID-19. This study provides the first evidence that SWD is a promising adjuvant therapy for COVID-19.

The safety and feasibility of the screening for retinopathy of prematurity assisted by telemedicine network during COVID-19 pandemic in Wuhan, China.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) epidemic, due to the traffic blockade and the shortage of medical resources, more and more premature infants could not receive timely and effective ROP screening, which delayed treatment and even caused children blindness. Therefore, how to carry out ROP screening safely and effectively during the epidemic was very important and urgent. This study aimed to evaluate the safety and feasibility of ROP screening assisted by telemedicine network during COVID-19 outbreak. METHODS: This retrospective study was conducted at Wuhan Children's hospital in Wuhan, China, from January to October, 2020. The measures which were performed to make the ROP screening more safe and effective were summarized and the comparison between ROP screening assisted by telemedicine network in 2020 and usual screening in 2019 were analyzed. RESULTS: A total of 267 outpatient infants completed ROP screening. The median gestational age was 32 weeks (30w to 34w) and the median birth weight was 1780 g (1460 g to 2100 g). Meanwhile, 149 (55.8%) out of 267 infants were males. During January to May in 2020, 86 screening appointments were received, among which 67 (77.9%) were from telemedicine platform online. The completing percentage of total online ROP appointments was higher than that of total face-to-face appointments (58.1% VS 22. 1%, P = 0.018). As for the number of infants screened between 2020 and 2019 from Februaryto October, 54 infants completed ROP screening in 2020, which was higher than that (51participants) in 2019 on September. Furthermore, compared with the usual screening in 2019, ROP screening assisted by telemedicine network in 2020 had smaller gestational age (32w VS 33w, p<0.001) and lower birth weight (1780 g VS 1900 g, p = 0.001). However, of the 267 infants screened, 18(6.7%) had ROP while the percentage of ROP screened in 2019 was the same (44[6.7%]). During follow-up, none of medical staffs was infected and no adverse reaction was reported. CONCLUSIONS: The screening for retinopathy of prematurity assisted by telemedicine network was safe and feasible during the COVID-19 pandemic. Preventive measures before and after screening were very necessary, which could effectively avoid cross infection.

The Application of Tissue Glue in Eyelid Laceration Repair in Children During the Coronavirus Disease 2019 Pandemic Lockdown in Wuhan.

OBJECTIVE: To discuss a rapid and effective treatment used for children with eyelid lacerations during the COVID-19 lockdown in Wuhan to limit the risk of cross-infection. METHODS: A comparative study was conducted of forty-five patients with eyelid lacerations who attended the Ophthalmology Department of Wuhan Children's Hospital between January 23, 2020 and March 6, 2020. The tissue glue Histoacryl was used to bond the wounds in 24 cases, while the traditional suture method was used for 21 cases. The wound healing time, complications, treatment satisfaction, and number of visits of the two groups were compared. RESULTS: The two groups had similar baseline characteristics. The wound healing time (from wound disinfection to wound dressing) was shorter in the tissue glue group (4.35 ± 0.47min versus 11.71 ± 1.85 min, P< 0.01). There was 1 case of wound dehiscence in the tissue glue group. Twenty-two cases in the tissue glue group were satisfied, 2 cases were basically satisfied, and 0 were dissatisfied. Eleven cases in the traditional suture group were satisfied, 9 cases were basically satisfied, and 1 case was dissatisfied. The difference was statistically significant (P < 0.05). In terms of the number of visits, the tissue glue group visited (1.54 ± 0.88) times, while the traditional suture group visited (2.38 ± 0.59) times. The difference between the two groups was statistically significant (P < 0.01). The real-time reverse transcriptase polymerase chain tests for severe acute respiratory syndrome coronavirus 2 of all medical staff in the ophthalmology emergency room were negative. CONCLUSION: Compared with the traditional suture method, tissue glue used in eyelid laceration in children has the advantages of painlessness, shorter operation duration, higher safety and satisfaction, greater ease of care, and fewer hospital visits. Tissue glue can be widely used to reduce the risk of cross-infection.
