Reflections and images: A place for art in medical physics?

The visual arts are rooted in the life of the wider community and may lack explicit medical physics reference. Nevertheless, they can be influential and can illustrate, communicate, and inform. They may also inspire, challenge, heal, give pleasure, help put one’s life in perspective and enrich the experience of being a practicing scientist working in medical physics.Eighteen works from 12 artists are presented. They are a convenience sample from the author’s experience. Two (Irish), though less well known, speak powerfully to scientists. Two are of the eighteenth century. The remaining works are modern from Europe, North America and Japan. All inform and challenge our behaviour as medical physicists.Headings guiding the paper address: historical perspectives; similarities of method between science and the arts; the hand as special expressions of being human; communicating science; science and a sense of wonder; borders to science; and the importance of a quiet, still, reflective approach. The author’s experience complements observations published by others.The artworks described delight and are an able ally in validating a life spent in science. They refresh it and are accessible to those willing to take a risk on the approach, with sensibility and an openness. The impact of art on science and medicine is also visible in under explored institutional art collections such as those housed at the IAEA in Vienna or WHO in Geneva.

Comparison of Clinical Efficacy and Safety between Misoprostol and Oxytocin in the Prevention of Postpartum Hemorrhage: A Meta-Analysis.

In order to systematically evaluate the clinical efficacy and safety of misoprostol versus oxytocin in the prevention of postpartum hemorrhage, this paper provides evidence-based reference for clinical medication, computerized retrieval of Chinese biomedical literature database (CBM), PubMed, Embase, Cochrane Library, and clinical trials. The retrieval period is from the establishment of each database to October 1, 2021. Published randomized controlled trials (RCTS) are included in this study. The literature is screened and evaluated according to inclusion and exclusion criteria, and meta-analysis is performed using RevMan 5.3 software. A total of 13 RCTS are included, with a total of 24754 parturients. The meta-analysis shows the average blood loss (SMD = 0.10, 95% CI (−0.11, 0.32), P=0.35), the time of the third stage of labor (SMD = 0, 95% CI (−0.07, 0.08), P=0.95), and blood transfusion rate (RR = 0.80, 95% CI (0.63, 1.02), P=0.07). However, the incidences of shivering (RR = 2.61, 95% CI (1.79, 0.81), P < 0.00001) and vomiting (RR = 2.78, 95% CI (1.85, 4.18), P < 0.00001) are significantly higher than those in oxytocin group. The effect of misoprostol on preventing postpartum hemorrhage is similar to that of oxytocin, but the incidence of adverse reactions is high, and the occurrence of adverse reactions should be closely watched in the use process. Due to the limitations of the included studies, multicenter, large-sample, and high-quality RCTS are still needed in the future to further verify this conclusion.

Student engagement in undergraduate medical education: A scoping review.

Student engagement is defined as behavioural, cognitive and emotional aspects of students' academic experience in teaching, learning and research through interacting with other students, faculty and community. Despite the growing interest in the field of student engagement, medical education research in this area is still fragmented. This scoping review aims to contribute to the understanding of measurements, drivers and outcomes of medical student engagement. The authors searched MEDLINE, PubMed, ProQuest, SCOPUS, ERIC, Science Direct and EBESCO for English articles published from 1990 until October 2021. In addition, we hand-searched key medical education journals and references in recently published articles. Using specific selection criteria, two authors independently reviewed the articles for eligibility, followed by data extraction using both quantitative and qualitative analysis. Of the 2136 retrieved articles, 51 studies were selected for the review, and 94% of them were published in the past 8years. The prevailing measures of student engagement failed to cover the multidimensionality of the construct with more focus on the behavioural dimension. Quantitative methods represented two thirds of the studies with a higher frequency of cross-sectional designs and using self-reports. The identified drivers of medical students' engagement are directed mainly to modifying the context of the learning environment. These factors increased student engagement by fostering relevance of learning, positive student relationships with peers and faculty, and enhancing student agency, and sense of competence. Cognitive engagement appears to be a positive predictor of academic achievement, but the relationship with other dimensions of engagement is controversial. Student engagement in undergraduate medical education is an important, yet under-researched construct. The research that does exist suggests engagement to be malleable, something that can be modified by different types of interventions taking into consideration the context of education and practice. Further research is required, however, to address the gaps identified in this review.

Effectiveness and Safety of SARS-CoV-2 Vaccines among Children and Adolescents: A Systematic Review and Meta-Analysis.

Background: The proportion of children and adolescents with COVID-19 had gradually increased according to data reported by WHO. However, there was no meta-analysis of effectiveness and safety of SARS-CoV-2 vaccines in children and adolescents. We aimed to provide investigation-based medical evidence and reference recommendations for children and adolescents in regard to SARS-CoV-2 vaccines. Methods: We systematically searched PubMed, Embase, and Web of Science from inception to 5 January 2022. RCTs and observational studies that examined the effectiveness and safety were included. Results: A total of 13 eligible studies were included for analysis. For the first dose, the effectiveness of SARS-CoV-2 vaccines against SARS-CoV-2 infection and COVID-19 was 88.5% (95% CI:15.7–98.4%, p = 0.033) and 84.3% (95% CI: 66.6–92.6%, p < 0.001) separately. For the second dose, the effectiveness against SARS-CoV-2 infection and COVID-19 was 91.6% (95% CI: 37.8–99.5%, p = 0.083) and 92.7 (95% CI: 82.2–97.0, p < 0.001) separately. Injection-site pain, fatigue, headache, anorexia, and axillary swelling were the top five adverse events after the first dose of SARS-CoV-2 vaccines. Fatigue, injection-site pain, headache, chills, and myalgia/muscle pain were the top five adverse events after the second dose of SARS-CoV-2 vaccines. Conclusions: SARS-CoV-2 vaccines had good effectiveness and safety in children and adolescents. We suggest that children and adolescents should get vaccinated as soon as possible to protect themselves and slow the spread of the pandemic.

Neurodevelopmental toxicity of pyrazinamide to larval zebrafish and the restoration after intoxication withdrawal

To investigate the neurotoxicity of pyrazinamide (PZA) to larval zebrafish, the PZA effects were assessed followed by its mechanism being explored. Same as isoniazid (INH), this compound is a first-line anti-tuberculosis drug and is suggested to be a risk that inducing nerve injury with long-term intoxication. Our findings indicated that zebrafish larvae obtained severe nerve damage secondary to constant immersion in various concentrations of PZA (i.e., 0.5, 1.0, and 1.5 mM) from 4 hpf (hours post fertilization) onwards until 120 hpf. The damage presented as dramatically decrease of locomotor capacity and dopaminergic neuron (DAN)-rich region length in addition to defect of brain blood vessels (BBVs). Moreover, PZA-administrated zebrafish showed a decreased dopamine (DA) level and downregulated expression of neurodevelopment-related genes, such as shha, mbp, neurog1, and gfap. However, secondary to 48-h restoration in fish medium (i.e., at 168 hpf), the neurotoxicity described above was prominently ameliorated. The results showed that PZA at the concentrations we tested was notably neurotoxic to larval zebrafish, and this nerve injury was restorable after PZA withdrawing. Therefore, this finding will probably provide a reference for clinical medication.

Avicenna and clinical experiences in Canon of Medicine.

Avicenna used his medical knowledge and experience of scientists from different nations to create a new style in medicine. For this reason, his textbook, Canon of Medicine, has been considered a medical reference in all universities worldwide for centuries. In this article, some valuable and interesting diagnostic and therapeutic clinical experiences mentioned in the Canon of Medicine are described in five sections. This research was conducted to review Avicenna’s specific clinical observations and interventions in PubMed, Google Scholar, and Scopus databases using the keywords “Avicenna” and “Canon of Medicine”. In this article, we presented several examples of diagnostic and therapeutic clinical experiences mentioned in the Canon of Medicine in 5 areas, including semiology, therapeutic strategy, urology, neurology, obstetrics, and gynecology. Canon of Medicine, as a complete medical series containing the medical experiences from different nations and Iranian medical scientists, has influenced the world’s medical knowledge for several centuries. Some of Avicenna’s clinical and experimental views can be useful from both a historical point of view and new research.

Studies on the Mechanism of the Volatile Oils from Caoguo-4 Decoction in Regulating Spleen Deficiency Diarrhea by Adjusting Intestinal Microbiota.

Background The Caoguo-4 decoction, a classical Mongolian medicine formula, is widely used to treat spleen deficiency diarrhea (SDD) in Mongolian for decades. Previously, the Caoguo-4 decoction volatile oil has been confirmed to be effective in ameliorating symptoms of spleen deficiency diarrhea in an animal model. However, the underlying mechanism of the Caoguo-4 decoction volatile oil is yet to be established. The aim of the current study was to investigate the antidiarrheal effects and mechanism of the Caoguo-4 decoction volatile oil. Method Wistar rats were randomly divided into 5 groups of 10 animals including control, model, positive, Caoguo-4 decoction, and Caoguo-4 decoction volatile oil groups (10 rats in each group). All the rats, besides those in the control group, were induced to develop SDD by a bitter-cold purgation method with Xiaochengqi decoction. The antidiarrheal effect of Caoguo-4 decoction volatile oil was evaluated by pathological section, serum D-xylose and AMS content, plasma MTL content, and gut microbiota analysis via 16S rRNA sequencing. Results The results showed that the developed SDD rat model (model group) had decreased food intake, increased weight loss, soft stool, and bad hair color. When compared with the control group, serum was significantly reduced serum D-xylose and AML but increased MTL levels in the model group (p < 0.05). However, after treatment with either the Caoguo-4 decoction (the decoction group) or Smecta (the positive group) or volatile oil from the Caoguo-4 decoction (the volatile oil group), a significant increase in the serum D-xylose levels was observed. Additionally, AML levels significantly increased in the positive and volatile oil groups, and MTL levels significantly decreased in the decoction and volatile oil groups, when compared with the model group (p < 0.05). The pathological changes of the intestinal mucosa showed that the structure of the epithelium in the villi of the small intestine was affected, deformed, and incomplete in the model group when compared with the control group. However, either the decoction group or the volatile oil group recovered the villous morphology. The results of OTU analysis and alpha diversity analysis of intestinal bacteria showed that the intestinal microbiota of the SDD model rats showed an obvious decrease in richness and diversity of intestinal microbiota. But the intervention treatment of decoction and volatile oil could significantly recover the richness and diversity of intestinal microbiota. Conclusion The intestinal microbiota destroyed in SDD modelling could be significantly improved by the Caoguo-4 decoction volatile oils, which provides reference for clinical medication.

Patient Perceptions of Dermatologic Photography: Scoping Review.

Medical photography is used extensively in dermatology to record disease progression, measure treatment response, and help teach patients about skin disease; such photos are also commonly utilized in teledermatology, medical education, research, and medical reference websites. Understanding patient perceptions of medical photographs obtained during dermatologic care in the clinic or hospital setting is critical to enable the delivery of high-quality, patient-centered medical care. The aims of this study were to elucidate patient perceptions of skin photos in dermatology and to explore possible next steps in improving the patient experience with medical photography in the hospital or clinic setting. A scoping review of the literature was performed using the PubMed database, with clinic- or hospital-based full-text publications in English spanning the last 10 years considered for inclusion. The majority of included studies (10/11, 91%) found positive patient attitudes toward medical photographs. The majority of patients (1197/1511, 79.2%) felt that medical photographs could improve medical care in the clinic setting. Written consent detailing all photo uses, including secondary uses (such as research or teaching), was preferred, apart from in 1 study. Patients preferred or found it acceptable for the photographer of their medical photos to be a physician (1301/1444, 90.1%). Clinic-owned cameras with departmental record storage were the preferred modality. Latinx and African American patients expressed less trust in the utility of medical photographs to improve care, compared with Asian and White patients. The minimal number of available publications on this topic and the inclusion of articles older than 5 years are limitations, since patient perceptions of medical photography may have rapidly changed during this time span, particularly in light of the COVID-19 pandemic and the subsequent increase in teledermatology visits. Patients reported positive perceptions of dermatologic photography for improving their medical care. Ethnic disparities in patient perceptions require further exploration to better elucidate nuances and develop interventions to improve the experience of marginalized patients. Building patient trust in nonphysician photographers may enhance clinic efficiency. Although clinic-owned cameras are well-accepted by patients, improved patient education surrounding the safety of electronic medical record phone applications is needed.

Penetration of COVID-19 Related Terminology into Legal, Medical, and Journalistic Discourses

March 2020 has become a moment of change in communication mode and quality. Previously, the media paid attention to the current affairs, however, never earlier the journalistic discourse has been so influentially affected by the ongoing phenomenon as in the case of COVID-19. Almost overnight the new terminological phenomena with specific legal or medical reference were introduced into everyday language mainly via mass media and become an important part of a pandemic related narration. The strong influence on the shape of the mentioned linguistic changes has mainly the adoption of new legal regulations due to the unexpected outbreak of the pandemic. The aim of the following paper is to investigate how COVID-19 pandemic affected the specialisation of the journalistic discourse and how different domains (law, medicine) are being influenced by new terminology and in other way round, how for example law and medicine influence new “COVID language”. In order to take the interdisciplinary nature of the issue into account, the degree of hybridity of the selected texts will be examined by means of selected material analysis. The methodology applied in the paper uses an empirical approach and comparative analysis. The material used for the analysis comes from the selected Polish quality and boulevard press. The paper concerns the linguistic influence of the “invisible enemy” on the language presented in press. The main findings reveal the intense use of neologisms, borrowings, and it shows that the discourse was changed linguistically thanks to Student’s t-test.

Quality-Based Evaluation of Patient-Facing Online Education Materials Regarding Facial Filler Procedures.

Injectable facial fillers have become tremendously more popular in recent years, and the Internet offers a proportional amount of consumer-facing educational material. This study sought to explore the quality of these online materials. The top 20 Web sites offering educational materials about facial filler were identified via Google search and sorted by source: Medical Professional Boards, Hospitals and Providers, Medical News and Reference, and Fashion. The materials were assessed for overall quality with the validated DISCERN instrument. The authors also assessed understandability and actionability (Patient Education Material Assessment Tool - PEMAT), accuracy, comprehensiveness, and readability (Flesch-Kincaid Grade Level and Flesch Reading Ease). The mean DISCERN score was 46.9 ± 7.6, which is considered "fair" quality educational material; above "poor," but below "good" and "excellent." Understandability and actionability scores were low, particularly with respect to visual aids. The materials were generally accurate (76-99%), but scored poorly in comprehensiveness, as 15% failed to mention any risks/adverse effects and only 35% mentioned cost. On average, readability was at an 11th grade level, far more complex than ideal (< 6th grade level). Information disseminated from seemingly reputable sources such as professional boards and hospitals/providers were not of higher quality or superior in any of the above studied domains. In conclusion, online educational materials related to injectable facial fillers are of subpar quality, including those from academic and professional organizations. Visual aids were particularly weak. The facial rejuvenation community should make a concerted effort to set a higher standard for disseminating such information.

The antagonistic effect of selenium on lead-induced apoptosis and necroptosis via P38/JNK/ERK pathway in chicken kidney

Lead (Pb), as a toxic heavy metal pollutant, has been paid much attention. Pb is often discharged into the environment through the soot, wastewater and waste residue in industrial production, which poses a great threat to animal health. Selenium (Se) is a trace element known to antagonize the toxicity caused by heavy metals. However, the interaction between Se and Pb in chicken kidney and its specific biological mechanism are still unclear. So, we constructed chicken models of Pb exposure and Pb, Se co-exposure. Therefore, we used western blot and qRT-PCR to detect the expression of related genes. The results showed that Pb activated the MAPK signaling pathway by up-regulating the expression of MARK pathway genes to induce the expression of pro-apoptotic genes and necroptosis-related genes. Se can regulate the MARK signaling pathway and attenuated the expression of MAPK pathway genes altered by Pb to reduce apoptosis and necroptosis of chicken kidney cells. Our study gives new ideas for the specific mechanism of Pb nephrotoxicity and provides a reference for comparative medicine and clinical medication.

Effects of RNA Modification "Writers" of GALNT2 on the Tumor Microenvironment in Cervical Squamous Cell Carcinoma.

Cervical squamous cell carcinoma (CESC) is one of the most common causes of cancer-related deaths in women. RNA modification "writers" modulate and alter RNA molecular activity and have been implicated in the origin and development of cancer. We explored the effects of RNA modification writers on the tumor microenvironment in CESC and their prognostic value. RNA modification writers were altered at the genetic and transcriptional levels in CESC sample data downloaded from The Cancer Genome Atlas and Gene Expression Omnibus databases. A principal component analysis (PCA) score model was established based on the genes screened by Cox regression analysis and random forest dimensionality reduction. A survival analysis of CESC patients revealed significant differences between patients with high and low scores. The gene set variation analysis method was used for a functional enrichment analysis. The relative abundance of immune cells in CESCs was quantified using the CIBERSORT algorithm. There were significant differences in multiple signaling pathways and immune cells between the patients with high and low scores. Based on Genomics of Drug Sensitivity in Cancer data, we analyzed the genetic mutations in CESCs and predicted the therapeutic effects of multiple anticancer drugs. Patients with high scores showed significant resistance. Finally, the N-acetylgalactosaminyltransferase 2 (GALNT2) was highly expressed in CESCs and was associated with multiple immune cells and the formation of the extracellular matrix. PCA score based on RNA modification writers is closely associated with immune infiltration in the tumor microenvironment and could be used as a reference for prognosis and medication in CESC patients.

Do Brazilian medical journals reference Brazilian articles? A cross-sectional study.

The quantity and quality of Brazilian scientific output increases decade by decade. However, there is a tendency to undervalue Brazilian journals, illustrated by the low number of citations compared with texts in international journals, with the tacit justification that foreign articles are of superior quality. To investigate the differences in numbers of citations of Brazilian and international periodicals in three Brazilian journals from 2016 to 2020. All articles published in the Journal of the Brazilian College of Surgeons, in the Jornal Vascular Brasileiro, and in Acta Cirúrgica Brasileira from 2016 to 2020 were analyzed. The references of these studies were analyzed, summing the total number of citations and classifying them as published in Brazilian or foreign journals. A total of 902 articles were analyzed, totaling 23,394 references, with a mean of 25.81 ± 8.59 references per article. Of these, 2,680 (11.45%) were Brazilian, equating to a mean of 2.95 ± 3.79 Brazilian references per article. It is necessary to improve appreciation of Brazilian periodicals, especially among Brazilian researchers and institutions responsible for science funding.

Efficacy and safety of Guhong injection for coronary heart disease: A protocol for systematic review and meta-analysis.

Background:Coronary heart disease (CHD) is considered one of the major causes of morbidity and mortality worldwide, posing a serious threat to public health. Current therapeutic approaches for CHD mainly focus on drug therapy, coronary artery bypass grafting, and percutaneous coronary intervention. However, there still exist some problems including drug side effects, adverse cardiac events after percutaneous coronary intervention. Guhong injection is a compound preparation of traditional Chinese medicine and western medicine. Several clinical studies have shown that Guhong injection can effectively relieve the clinical symptoms of CHD patients and improve clinical efficacy. However, there is no systematic review to evaluate the effectiveness and safety of Guhong injection in treating CHD. Therefore, in this study we will plan to systematic review to evaluate the effectiveness and safety of Guhong injection for CHD, providing a strong evidence-based medical reference for clinical use.Methods:The database search includes EMBASE, PubMed, Cochrane Library, Web of Science, China National Knowledge Infrastructure, WanFang Database, Chinese Biomedical Database, Chinese Scientific Journal Database. The retrieval time was from their inception to November 30, 2021. The main outcome indicators include the frequency, severity, and duration of angina pectoris attacks, electrocardiogram changes, and dose of nitroglycerin. The analysis software uses RevMan 5.3.Results:By collecting the existing evidence, the results of this study will systematically evaluate the effects of Guhong injection in the treatment of CHD.Conclusion:The results of this study will provide evidence for the efficacy and safety of Guhong injection in the treatment of CHD.INPLASY Registration number:INPLASY2021120032.

Medical Support for California Wildfire Response.

Wildfires have become a regular seasonal disaster across the Western region of the United States. Wildfires require a multifaceted disaster response. In addition to fire suppression, there are public health and medical needs for responders and the general population in the path of the fire, as well as a much larger population impacted by smoke. This paper describes key aspects of the health and medical response to wildfires in California, including facility evacuation and shelter medical support, with emphasis on the organization, coordination, and management of medical teams deployed to fire incident base camps. This provides 1 model of medical support and references resources to help other jurisdictions that must respond to the rising incidence of large wildland fires.

Prediction of total hospital expenses of patients undergoing breast cancer surgery in Shanghai, China by comparing three models

BackgroundBreast cancer imposes a considerable burden on both the health care system and society, and becomes increasingly severe among women in China. To reduce the economic burden of this disease is crucial for patients undergoing the breast cancer surgery, hospital managers, and medical insurance providers. However, few studies have evidenced the prediction of the total hospital expenses (THE) for breast cancer surgery. The aim of the study is to predict THE for breast cancer surgery and identify the main influencing factors.MethodsData were retrieved from the first page of medical records of 3699 patients undergoing breast cancer surgery in one tertiary hospital from 2017 to 2018. Multiple liner regression (MLR), artificial neural networks (ANNs), and classification and regression tree (CART) were constructed and compared.ResultsThe dataset from 3699 patients were randomly divided into training and test sets at a 70:30 ratio (2599 and 1100 records, respectively). The average total hospital expenses were 12520.54 ± 7844.88 ¥ (US$ 1929.20 ± 1208.11). MLR results revealed six factors to be significantly associated with THE: age, LOS, type of disease, having medical insurance, minimally invasive surgery, and receiving general anesthesia. After comparing three models, ANNs was the best model to predict THEs in patients undergoing breast cancer surgery, and its strong predictive performance was also validated.ConclusionsTo reduce the THEs, more attention should be paid to related factors of LOS, major and minimally invasive surgeries, and general anesthesia for these patient groups undergoing breast cancer surgery. This may reduce the information asymmetry between doctors and patients and provide more reliable cost, practical inpatient medical consumption standards and reimbursement standards reference for patients, hospital managers, and medical insurance providers ,respectively.

Efficacy of a combination of sildenafil and magnesium sulfate in the treatment of persistent pulmonary hypertension of the newborn, and its influence on hemodynamics

Purpose: To investigate the efficacy of the combined use of sildenafil and magnesium sulfate in the treatment of persistent pulmonary hypertension of the newborn (PPHN), and its influence on hemodynamics.Methods: A total of 174 children with persistent pulmonary hypertension who were treated in Ganzhou People’s Hospital, Ganzhou, China were selected and randomly assigned to joint group (JG) and control group (CG), with 87 patients in each group. The CG group received magnesium sulfate, while the JG group received sildenafil plus magnesium sulphate. The respiratory parameters of the children were analyzed using blood gas analyzer, while their hemodynamic indices were evaluated using color Doppler echocardiography. The levels of cytokines and inflammatory factors were determined by enzyme-linked immunosorbent assay (ELISA).Results: Time taken for symptom disappearance, oxygen therapy, and hospitalization period were shorter in JG than in CG (p &lt; 0.05). Post-treatment, the respiratory parameters (PaO2, PaCO2, and SaO2) in both groups s improved, with lower levels of PaO2 and PaCO2, and a higher level of SaO2 in JG (p &lt; 0.05). Following treatment, the levels of systemic vascular resistance (SVR), posterior pulmonary vascular resistance (PVR) and pulmonary artery pressure (PA) in JG were significantly reduced, relative to CG (p &lt; 0.05). Similarly, the expression of endothelin -1 (ET-1), brain natriureticpeptide (BNP), and angiotensin 1 (ANG-1) improved, with lower levels of ET-1 and BNP, and a higher level of ANG-1 in JG (p &lt; 0.05). There was post-treatment reduction as well in IL-6 and TNF-α, with lower levels in JG (p &lt; 0.05). Patients in JG showed higher total treatment effectiveness and a lowerincidence of adverse reactions than those in CG (p &lt; 0.05).Conclusion: The combined use of sildenafil and magnesium sulfate enhances the management of PPHN, ameliorates respiratory parameters, hemodynamics, and levels of cytokines and inflammatory factors. These findings provide evidence-based medical references for a new treatment strategy for PPHN.

Mucopolysaccharidosis patients have reduced functional capacity.

Mucopolysaccharidoses (MPSs) are a group of rare diseases caused by an intralysosomal accumulation of glycosaminoglycans, resulting in a multisystemic clinical condition characterized by variable degrees of physical-functional impairment. To evaluate the functional capacity (FC) of MPS patients and compare with a healthy control group. This is a cross-sectional study of 6- to 39-year-old patients followed at a medical reference center and compared with their control peers, matched by age and sex. FC was assessed using the Sit-to-Stand Test (SST) and Incremental Shuttle Walk Test (ISWT). Heart rate (HR) and Borg rating of perceived exertion were measured before and after ISWT. HR recovery (HRR) was defined as the HR at the end of the test minus the HR in the second minute after ISWT. Nineteen (19) MPS patients, 69% with type II MPS and mean age 17 ± 11 years were evaluated. Every patient was under enzyme replacement therapy. The time to perform the SST was longer in the MPS group (10.6 ± 2.5 s vs. 6.7 ± 1.2 s; p < .01). The MPS group achieved lower values of distance covered on the ISWT (407.6 ± 329.8 m vs. 1131.9 ± 183.3 m; p < .01), with a significantly higher Borg (6 [5-8] vs. 2 [1-4]; p = .02). The MPS group's HRR was slower than the controls (32.9 ± 20.2 beats per minute [bpm] vs. 69.1 ± 25.9 bpm; p < .001). We observed a pronounced reduction in the MPS group's FC compared to their healthy peers and a worse HRR after completing the test.

Efficacy of acupuncture combined with Chinese herbal medicine for the treatment of chronic nephritis: A protocol for systematic review and meta-analysis.

Background:Chronic nephritis is a common kidney disease that afflicts people worldwide. The disease has main manifestations of proteinuria, hematuria, edema, and hypertension that are associated with kidney-damaging processes that eventually lead to kidney failure. Traditional Chinese medicine involving combination treatment with herbal remedies and acupuncture has been shown clinically to alleviate chronic nephritis, although to date no systematic review of the efficacy of this combination treatment for this purpose has been reported, prompting this study. Here we conducted a systematic review and meta-analysis of published randomized clinical trials to scientific evidence and credible medical references supporting the clinical efficacy of this combination treatment when used to treat chronic nephritis.Methods:We will search the following 8 electronic Chinese and English databases: Web of Science, PubMed, Cochrane Library, Embase, China Biomedical Literature Database, China National Knowledge Infrastructure, China Scientific Journal Database, and the Wanfang database. All electronic databases will be searched from inception to October 10, 2021. All statistical analyses will be performed using Review Manager Version 5.4 provided by the Cochrane Collaboration Network.Results:The protocol for systematic review and meta-analysis will be applied to evaluate the efficacy of acupuncture combined with Chinese herbal medicine for the treatment of chronic nephritis.Conclusion:We plan to submit the results of this research to a peer-reviewed journal.INPLASY registration number:INPLASY2021100051.
