RESUMEN
INTRODUCTION AND HYPOTHESIS: Catheterization is a common treatment for postpartum urinary retention (PUR); however, its application before diagnosis of PUR remains unclear. The aim was to give an overview of the existing literature on the effectiveness and safety of intrapartum or postpartum catheterization in the prevention of PUR. METHODS: This scoping review followed a methodological framework. PubMed, the Cochrane Library, Embase, Web of Science, the China National Knowledge Infrastructure, WanFang, the China Science and Technology Journal Database, and the China Biomedical Literature Database were searched from the inception of each database to 21 May 2023. RESULTS: The search revealed 16 studies examining three different catheterization methodologies, including 12 intrapartum studies. Ten studies concluded that intrapartum or postpartum catheterization prevented PUR, two of which were only for overt or covert PUR. In 4 out of 13 experimental studies, no significant difference was found: one for intrapartum catheterization versus routine nursing, the other for intrapartum or postpartum intermittent versus indwelling catheterization. However, one found that postpartum disposable catheterization after ineffective targeted care reduced the incidence of PUR compared with indwelling catheterization. One out of the 3 case-control studies concluded that prenatal catheterization ≥2 times was a risk factor for PUR. CONCLUSIONS: Based on the findings in this scoping review, catheterization prior to the diagnosis of PUR appears to play a role in preventing PUR and is safe. Preliminary evidence is accumulating on the effectiveness of three types of catheterization methods in preventing PUR, but more comprehensive studies are needed to establish these findings.

BACKGROUND: To compare the effect of different noninvasive external therapies of traditional Chinese medicine (TCM) on the prevention of postpartum urinary retention (PUR) using a network meta-analysis (NMA). METHODS: A search of the China National Knowledge Infrastructure, WanFangDate, VIP, China Biomedical Literature Database, PubMed, The Cochrane Library, Embase, and Web of Science databases were reviewed for related randomized controlled trials dated between database inception and December 31, 2022, on the prevention of PUR by noninvasive TCM. Two researchers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies; then, a NMA was performed using Revman5.3 software, State13.1 software, and frequency methodology. RESULTS: In total, 16 studies involving 3637 cases of parturients and 9 types of noninvasive TCM external treatments were incorporated into the NMA. The NMA results show that based on routine nursing, in terms of reducing the incidence of urinary retention, acupoint compressing combined with auricular acupressure is ranked first, followed by acupoint hot compress, acupoint massage combined with auricular acupressure, Yin-Yang therapy, acupoint massage, auricular acupressure, acupoint compressing, and routine nursing. In terms of urination time, acupoint compressing combined with auricular acupressure ranked first, followed by acupoint massage combined with auricular acupressure, acupoint electrical stimulation, acupoint compressing, TCM heating therapy, acupoint massage, auricular acupressure, and routine nursing. In terms of reducing residual urine volume after the first urination, acupoint compressing combined with auricular acupressure was ranked first, followed by auricular acupressure, acupoint compressing, acupoint massage, TCM heating therapy, and routine nursing. CONCLUSION: Current evidence shows that acupoint compressing combined with auricular acupressure may be the best noninvasive TCM treatment for preventing PUR based on routine nursing; however, further high-quality clinical randomized controlled trials are needed for validation and support.

BACKGROUND: Large skin defects severely disrupt the overall skin structure and can irreversibly damage sweat glands (SG), thus impairing the skin's physiological function. This study aims to develop a stepwise reprogramming strategy to convert fibroblasts into SG lineages, which may provide a promising method to obtain desirable cell types for the functional repair and regeneration of damaged skin. METHODS: The expression of the SG markers cytokeratin 5 (CK5), cytokeratin 10 (CK10), cytokeratin 18 (CK18), carcino-embryonic antigen (CEA), aquaporin 5 (AQP5) and α-smooth muscle actin (α-SMA) was assessed with quantitative PCR (qPCR), immunofluorescence and flow cytometry. Calcium activity analysis was conducted to test the function of induced SG-like cells (iSGCs). Mouse xenograft models were also used to evaluate the in vivo regeneration of iSGCs. BALB/c nude mice were randomly divided into a normal group, SGM treatment group and iSGC transplantation group. Immunocytochemical analyses and starch-iodine sweat tests were used to confirm the in vivo regeneration of iSGCs. RESULTS: EDA overexpression drove HDF conversion into iSGCs in SG culture medium (SGM). qPCR indicated significantly increased mRNA levels of the SG markers CK5, CK18 and CEA in iSGCs, and flow cytometry data demonstrated (4.18 ± 0.04)% of iSGCs were CK5 positive and (4.36 ± 0.25)% of iSGCs were CK18 positive. The addition of chemical cocktails greatly accelerated the SG fate program. qPCR results revealed significantly increased mRNA expression of CK5, CK18 and CEA in iSGCs, as well as activation of the duct marker CK10 and luminal functional marker AQP5. Flow cytometry indicated, after the treatment of chemical cocktails, (23.05 ± 2.49)% of iSGCs expressed CK5+ and (55.79 ± 3.18)% of iSGCs expressed CK18+, respectively. Calcium activity analysis indicated that the reactivity of iSGCs to acetylcholine was close to that of primary SG cells [(60.79 ± 7.71)% vs. (70.59 ± 0.34)%, ns]. In vivo transplantation experiments showed approximately (5.2 ± 1.1)% of the mice were sweat test positive, and the histological analysis results indicated that regenerated SG structures were present in iSGCs-treated mice. CONCLUSION: We developed a SG reprogramming strategy to generate functional iSGCs from HDFs by using the single factor EDA in combination with SGM and small molecules. The generation of iSGCs has important implications for future in situ skin regeneration with SG restoration.

BACKGROUND: A voluntary procedure for reporting adverse drug reactions (ADRs) was formally put in place in 1989. However, only a small proportion of ADR reports are actually forwarded to the national monitoring center. To identify the reasons for underreporting, the authors investigated the awareness and attitudes of healthcare professionals (doctors, nurses, and administrators) toward the ADR system in China. In addition, the authors sought to formulate approaches to improve the current ADR reporting system. METHODS: Structured interviews were carried out in 16 hospitals selected from 27 municipal hospitals in Wuhan, Hubei Province, China. A questionnaire survey of a stratified random sample of approximately 15% of healthcare professionals in each selected hospital was conducted during February to March 2003. RESULTS: The response rate of this survey was 85%. One thousand six hundred and fifty-three questionnaires were used in the final analysis. Only 2.7% of the healthcare professionals had a correct understanding to the definition of ADR. Eighty-nine point two percent of the healthcare professionals had encountered ADRs. Ninety-four percent of them were aware of the need to report these to the ADR monitoring center. However, only 28.5% of doctors, 22.8% of nurses, and 29.7% of administrators actually submitted a report. For the most part, they reported ADRs to the hospital pharmacy (66.0%), to other departments in the hospital (72.5%), and to the pharmaceutical industry (23.0%), rather than to the national monitoring center (2.9%) or regional monitoring center (9.5%). Severe or rare ADRs and ADRs to new products were generally perceived to be significant enough to report. Sixty-two point one percent of the healthcare professionals had encountered ADRs, yet not reported them to anybody. The major reasons for not reporting included no knowledge of the reporting procedure (71.4%), unavailability of the reporting center mailing address (67.9%), unavailability of the ADR report form (60.4%), lack of knowledge of the existence of a national ADR reporting system (52.2%), and belief that the ADR in question was already well known (44.1%). CONCLUSIONS: Healthcare professionals in Wuhan, China have little basic knowledge of ADR and of the voluntary reporting system. The main reasons for underreporting were lack of basic knowledge about ADRs and the voluntary reporting procedure. Education and training of healthcare professionals is needed to improve the current ADR reporting system.

OBJECTIVE: To investigate the knowledge and attitudes of healthcare professionals (doctors, nurses and administrators) to adverse drug reactions (ADR) in Wuhan city and to identify the reasons for under-reporting. METHODS: Structured interviews were carried out in Wuhan, Hubei province. Questionnaire survey to approximately 15% of the medical practitioners selected from 16 hospitals, was conducted during the period from February to March 2003. RESULTS: Only 2.7% of the interviewees knew the definition of adverse drug reactions. 61.7% of the doctors, 62.7% of the nurses and 61.1% of the administrators had ever encountered an ADR during their practices, but did not report to the national monitoring center or other centers. The major reasons for not reporting included: ignorant about the requirement and the reporting process of ADR (71.4%); address of the reporting agency and Forms unavailable (67.9%, 60.4%); unaware of the existence of a national ADR reporting system (52.2%); needless to report as the ADR being too well known (44.1%). They mainly reported an ADR to the hospital pharmacy or other departments, or to the pharmaceutical administration. Education, training and developing new institutions were ways to improve the reporting system. CONCLUSIONS: Our results showed that healthcare professionals had little knowledge on the basic ADR knowledge. The main reasons for underreporting were related to factors on reporting process, address of related centers and unavailable of the Forms. Education and training to doctors and nurses to enhance the awareness of administrators were the ways to improve the reporting system.
