RESUMO
OBJECTIVE: This meta-analysis was conducted to assess the effectiveness of photodynamic therapy (PDT) as an adjunct to conventional mechanical debridement (CMD) for the management of peri-implant mucositis (p-iM). METHODS: We systematically searched four databases (PubMed, Embase, Web of Science, and Cochrane Library) for randomized controlled trials (RCTs) investigating PDT + CMD for p-iM from their inception to March 13, 2023. Meta-analysis was performed using RevMan 5.4 software. RESULTS: Seven RCTs met the inclusion criteria. The meta-analysis revealed that PDT + CMD treatment was more effective than CMD alone in reducing probing depth (PD) (Mean Difference [MD]: -1.09, 95% Confidence Interval [CI]: -1.99 to -0.2, P = 0.02) and plaque index (PI) (MD: -2.06, 95% CI: -2.81 to -1.31, P < 0.00001). However, there was no statistically significant difference in the improvement of bleeding on probing (BOP) between the PDT + CMD groups and CMD groups (MD: -0.97, 95% CI: -2.81 to 0.88, P = 0.31). CONCLUSIONS: Based on the current available evidence, this meta-analysis indicates that the addition of PDT to CMD significantly improves PD and PI compared to CMD alone in the treatment of p-iM. However, there is no significant difference in improving BOP.

The transition of macrophages from the proinflammatory M1 to the anti-inflammatory M2 phenotype is crucial during the wound healing process. In this study, we assess the role of chemokine (C-C motif) ligand 6 (CCL6) in modulating macrophage polarization and wound healing. Initially, we observed significantly upregulated CCL6 expression in the skin tissue on the edge of the wound during the inflammation and proliferation phases. Furthermore, we discovered that the mice treated with rCCL6 had significantly accelerated wound healing and increased levels of M2-type macrophages. Using in vitro models, we found that CCL6 promotes the M2 polarization of macrophages by activating the PI3-kinase/Akt signalling pathway. Additionally, our results showed that CCL6 inhibited macrophage autophagy and accelerated wound healing, whereas the autophagy inducer rapamycin delayed wound healing. Finally, we determined that the PI3-kinase inhibitor LY294002 promoted macrophage autophagy and decreased M2 macrophages, indicating the importance of PI3-kinase in M2 polarization, and this process was reversed by CCL6. Taken together, our study demonstrates that CCL6 promotes M2 polarization, inhibits macrophage autophagy, and accelerates skin wound healing by activating the PI3-kinase/Akt signalling pathway.

OBJECTIVE: The aim of this review is to evaluate the different medicinal interventions available for the management of oral submucous fibrosis (OSF). MATERIALS AND METHODS: We conducted a comprehensive electronic search on PubMed, Web of Science, and Cochrane Library databases for articles related to OSF patients treated with medications from December 2011 to September 2022. GRADE system was used to evaluate the evidence quality. The reporting of the systematic review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The main outcomes were the improvement of maximum mouth opening, burning sensation, cheek flexibility, and tongue protrusion. RESULTS: Twenty-nine randomized controlled trials (RCTs), five clinical trials (CCTs) were included, and the use of drugs for OSF treatment were evaluated. Drugs like steroids, hyaluronidase, pentoxifylline, lycopene, curcumin, dpirulina, aloe vera, omega3, oxitard, allicin, colchicine have been used. It was found that drugs with evidence high quality were salvia miltiorrhiza combined with triamcinolone acetonide, lycopene, pentoxifylline, curcumin, and aloe vera, and those with evidence moderate quality were allicin, colchicine, omega 3, and oxitard. CONCLUSION: Based on the results of our comprehensive analysis, for long-term treatment, we found lycopene with low side effects, whereas for relieving the symptoms of severe burning sensation, aloe vera is the most effective. Although the recent review has made some progress, drug therapy for OSF remains unclear, and more high-quality RCTs are needed to identify better treatments for OSF.

Proliferation and migration of keratinocytes are vital processes for the successful epithelization specifically after wounding. MiR-221 has been identified to play a potential role in promoting wound regeneration by inducing blood vessel formation. However, little is known about the role of miR-221 in the keratinocyte proliferation and migration during wound healing. An in vivo mice wound-healing model was generated; the expression levels of miR-221 were assessed by qRT-PCR and fluorescence in situ hybridization. Initially, we found that miR-221 was upregulated in the proliferative phase of wound healing. Further, in an in vivo wound-healing mice model, targeted delivery of miR-221 mimics accelerated wound healing. Contrastingly, inhibition of miR-221 delayed healing. Additionally, we observed that overexpression of miR-221 promoted cell proliferation and migration, while inhibition of miR-221 had the opposite effects. Moreover, we identified SOCS7 as a direct target of miR-221 in keratinocytes and overexpression of SOCS7 reversed the effects of miR-221 in HaCaT keratinocytes. Finally, we identified that YB-1 regulates the expression of miR-221 in HaCaT keratinocytes. Overall, our experiments suggest that miR-221 is regulated by YB-1 in HaCaT keratinocytes and acts on SOCS7, thereby playing an important role in HaCaT keratinocyte proliferation and migration during wound healing.

BACKGROUND: TGF-ß1 promotes keratinocyte migration and re-epithelialization of cutaneous wounds during the wound healing process. Decreased SOCS7 expression has been associated with increased healing potential. However, the relationship between TGF-ß1 and SOCS7 in wound re-epithelialization remains unclear. OBJECTIVES: To investigate the relationship between TGF-ß1 and SOCS7 in the re-epithelialization of keratinocytes during skin wound healing. METHODS: The expression of SOCS7 under different concentrations of TGF-ß1 was detected by WB and qPCR. The migration ability of keratinocytes was detected by scratch and Transwell assay. Protein interactions were detected by ChIP and luciferase assay. The effect of SOCS7 on skin healing in mice was detected in animal model. RESULTS: In this study, we found that SOCS7 was downregulated by TGF-ß1 and that overexpression of SOCS7 led to suppression of TGF-ß1-induced keratinocyte migration through inhibition of the PI3K/AKT and MEK/ERK pathways. Also, TGF-ß1 negatively regulated SOCS7 expression at the transcriptional level through the binding of EGR1 to the EGR1/SP1 overlapping binding sites in the SOCS7 promoter. CONCLUSION: Taken together, our findings show that TGF-ß1-induced EGR1 expression is required for repression of SOCS7, which promotes keratinocyte migration and re-epithelialization during wound healing. Finally, our study identifies the TGF-ß1/EGR1/SOCS7 pathway as a potential therapeutic target to promote wound healing. Video Abstract.

OBJECTIVE: This meta-analysis was performed to systematically evaluate the efficacy of hyaluronidase combined with corticosteroids compared with other drugs in improving maximum mouth opening and alleviating the burning sensation in patients with oral submucous fibrosis (OSF). METHODS: PubMed, Embase, Web of Science and the Cochrane Library were searched. RevMan 5.3 software was used for the meta-analysis. RESULTS: Six studies involving 244 patients with OSF were analysed. No significant difference in improvement of maximum mouth opening was found between the hyaluronidase and control groups (lycopene, pentoxifylline, aloe vera, dexamethasone, Turmix [curcumin + piperine] and isoxsuprine) at 1 month (mean difference [MD]: 0.32, 95% confidence interval [CI]: -0.92-1.56, P = .61, I2 = 57%), 2 months (MD: 0.49, 95% CI: -0.14-1.12, P = .12, I2 = 41%) or 3 months (MD: 0.40, 95% CI: -1.08-1.87, P = .60, I2 = 92%). Additionally, no statistically significant difference was found in alleviation of the burning sensation between the two groups at 1 month (MD: 0.54, 95% CI: -0.62-1.71, P = .36, I2 = 0%), 2 months (MD: 0.53, 95% CI: -0.85-1.91, P = .45, I2 = 0%) or 3 months (MD: 0.64, 95% CI: -1.07 to 2.35, P = .46, I2 = 0%). CONCLUSIONS: According to this meta-analysis, weak evidence indicates that hyaluronidase combined with corticosteroids has no additional clinical benefit over control drugs (lycopene, pentoxifylline, aloe vera, dexamethasone, Turmix and isoxsuprine) in improving maximum mouth opening and alleviating the burning sensation in patients with OSF. Therefore, more high-quality, multi-centre randomized controlled trials with larger samples are needed to further assess the efficacy of hyaluronidase combined with corticosteroids in the treatment of OSF.

OBJECTIVES: Explore how to manage oral healthcare during the COVID-19 outbreak. MATERIALS AND METHODS: In order to solve oral healthcare during the COVID-19 outbreak, our hospital has taken effective measures: build a team of experts, which provide a 24-h hotline, online video consultation, and online training and push popular science articles on WeChat. For the treatment of emergency patients aside from routine epidemic prevention measures, some special measures for oral treatment need to be added. RESULTS: From January 23, 2020, to March 2, 2020, a total of 3035 patients received oral therapy during the COVID-19 epidemic in our hospital. To our knowledge, no oral health worker or patient has been infected with COVID-19 due to oral treatment, and no patients have complained about the suspension of treatment by complaints hotline. CONCLUSION: COVID-19 is a novel challenge for oral healthcare. Attention should be paid to oral healthcare during the outbreak of COVID-19. CLINICAL RELEVANCE: These experiences of oral healthcare can be used as a reference by stomatological hospitals and oral clinics during public health emergencies.

OBJECTIVES: The aim of this meta-analysis was to systematically evaluate the efficacy of lycopene in improving maximum mouth opening and other clinical symptoms in patients with oral submucous fibrosis (OSF). METHODS: We searched 5 databases: PubMed, Web of Science, Embase, The Cochrane Library, and EBSCO. Randomized controlled trials were collected to evaluate the efficacy of lycopene in the treatment of OSF. Each database was searched from inception to April 30, 2019. The RevMan 5.3 software was used for this meta-analysis. RESULTS: The included studies were 7 randomized controlled trials involving 758 patients with OSF. The results of this meta-analysis showed that lycopene was significantly more effective in improving maximum mouth opening in OSF patients than placebo treatment (mean difference [MD]: 3.15; 95% confidence interval [CI]: 2.19-4.10, P < .0001, I2 = 0%). Compared with control groups, lycopene could significantly increase the maximum mouth opening in patients with OSF after 1 month of treatment (MD, 2.40; 95% CI, 2.22-2.58; P = .91; I2 = 0%), 2 months of treatment (MD, 3.19; 95% CI, 2.87-3.51; P = .93; I2 = 0%), and 3 months of treatment (MD, 4.89; 95% CI, 4.51-5.28; P = .86; I2 = 0%). However, no significant difference was found in alleviation of burning sensation after 1 month (risk ratio [RR], 1.04; 95% CI, 0.89-1.23; P = .73; I2 = 0%), 2 months (RR, 0.98; 95% CI, 0.73-1.31; P = .69; I2 = 0%), and 3 months of treatment (RR, 0.84; 95% CI, 0.47-1.52; P = .81; I2 = 0%); tongue protrusion (MD, -1.59; 95% CI, -4.15 to 0.97; P = .12; I2 = 58%); and pain associated with the lesion after 1 month (RR, 1.05; 95% CI, 0.92-1.21; P = .77; I2 = 0%), 2 months (RR, 0.95; 95% CI, 0.75-1.19; P = .35; I2 = 0%), and 3 months (RR, 0.95; 95% CI, 0.68-1.33; P = .14; I2 = 51%) in patients with OSF between lycopene and control groups. CONCLUSIONS: The results of this meta-analysis showed that lycopene is more effective for improving symptoms of maximum mouth opening than placebo groups and control groups, but there were no significant differences in burning sensation, pain associated with lesion, and tongue protrusion in patients with OSF compared with control groups.

The reconstruction of large full-thickness scalp defects remains a surgical challenge, especially when the skull is exposed completely without periosteum. Surgical technique options for wound coverage have included tissue expansion, skin grafting, local or regional flaps, and microvascular free tissue transfer. In recent years, some authors have reported to use biological material as an alternative for repairing complex wounds. The authors report the successful reconstruction of a large defect with bare skull in bilateral temporal regions of a 3-year-old child. The patient was treated with artificial biomaterial followed by skin grafting, without making multiple cranial burr holes or burring out the outer bony cortex. The relevant literatures were reviewed and the vascular anatomy evidence of the blood supply at temporal region was also demonstrated on cadaver. This case suggests that artificial biomaterial followed by skin grafting is a potential alternative for the treatment of large full-thickness scalp defects in pediatric patients.

BACKGROUND: The occurrence of oral submucous fibrosis (OSF) is often accompanied by an increase in lactate dehydrogenase (LDH) levels. In this meta-analysis, we compared the salivary and serum levels of LDH levels between OSF patients and controls. MATERIAL AND METHODS: A comprehensive search was conducted in PubMed, Embase, Web of Science, and Cochrane Library from the establishment of the database to June 2023, and the quality of the studies was checked by the Newcastle-Ottawa Quality Assessment scale. The mean difference (MD) and 95% confidence interval (CI) were calculated using RevMan 5.4 software. RESULTS: A total of 28 studies were retrieved from the database, and we included 5 studies in this meta-analysis. The salivary LDH level of OSF patients was higher than healthy controls (MD: 423.10 pg/L 95%CI: 276.42-569.77 pg/mL, Pâ <â .00001), the serum LDH level of OSF patients was also higher than that of healthy controls (MD: 226.20 pg/mL, 95%CI: 147.71-304.69 pg/mL, Pâ <â .00001). CONCLUSIONS: This meta-analysis showed that salivary and serum LDH levels were higher in OSF patients than in healthy controls, suggesting that LDH may be a potential biomarker for OSF.

Peanut skin (PS) contains various flavonoids and phenols that have antitumor and antioxidant effects. However, no research has been conducted on PS and hepatocellular carcinoma (HCC). Therefore, this study sought to explore the potential mechanism of PS in treating HCC. PS was searched for in the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and SYMMAP databases. HCC targets were searched for in five major databases. Protein-protein interaction network, Gene Ontology, and Kyoto Encyclopedia of Genes and Genomes analyses were performed. Molecular docking and molecular dynamics simulation were used for verification. Furthermore, in vitro experiments were used to verify the regulation of PS on human HCC (HepG2) cells. Ten ingredients and 95 common targets were identified for PS and HCC, respectively. The key targets of ingredients mainly relate to pathways such as hepatitis B, lipid and atherosclerosis, advanced glycation end products (AGEs)-AGE receptors (RAGEs) signaling pathway in diabetic complications, interleukin-17 (IL-17) signaling pathway, mitogen activated kinase-like protein (MAPK) signaling pathway, the PI3K-Akt signaling pathway. In addition, the molecular docking and molecular dynamics simulation analysis indicated the ingredients had strong binding ability with the targets. Moreover, in vitro experiments confirmed that luteolin can promote the apoptosis of HepG2 cells by controlling the expression of phosphorylated protein-tyrosine kinase (p-AKT). This study provides preliminary evidence that PS produces a marked effect in regulating multiple signaling pathways in HCC through multiple ingredients acting on multiple core genes, including AKT serine/threonine kinase 1 (AKT1), MYC, caspase 3 (CASP3), estrogen receptor 1 (ESR1), epidermal growth factor receptor (EGFR), jun proto-oncogene(JUN), and provides the basis for follow-up research to verify the mechanism of action of PS in treating HCC.

PURPOSE: To evaluate the effect of MB-PDT assisted essential therapy on angle resorption of lower anterior alveolar bone in patients with periodontitis. METHODS: Forty patients who were diagnosed with periodontitis stage III-IV or C, lower anterior teeth alveolar bone angle resorption, and periodontal pocket depth greater than 4 mm were selected from April 2018 to October 2020 in the Department of Periodontology and Oral Mucosal Diseases, Changsha Stomatological Hospital. The patients were randomly divided into control group and experimental group with 20 cases in each group. Compared with the control group which was only managed with essential treatment, the experimental group was treated with MB-PDT on the basis of the control group. The plaque index (PLI) and gingival bleeding index (GBI) scores of the two groups were recorded before surgery and 1 and 2 weeks after surgery. Probing depth (PD) and clinical attachment level (CAL) were detected before and 6 months after surgery. Statistical analysis of the data was performed using Graphpad Prism 5 software package. RESULTS: The PLI and GBI of the experimental group were significantly lower than those of the control group at 1 and 2 weeks after operation(Pï¼0.05). Six months after surgery, PD and CAL levels in the experimental group were significantly lower than those in the control group (Pï¼0.05). CONCLUSIONS: MB-PDT adjuvant therapy has the advantages of simple operation, efficient sterilization, promotion of healing, and high safety performance. It may be a new non-surgical adjuvant treatment strategy for effective treatment of lower anterior alveolar angular resorption.

OBJECTIVE: Oral submucous fibrosis (OSF) is a chronic, insidious, progressive mucosal disease that may be affected by mutations in the Wnt/ß-catenin signaling pathway. Panax notoginseng saponins (PNS) is a powerful anti-fibrosis agent; however, its effect and mechanism in treating OSF remain unclear. This study investigated the effect and mechanism of PNS treatment for OSF. STUDY DESIGN: Arecoline was used to induce OSF models in vivo and in vitro, which were then treated with PNS. Hematoxylin-eosin (HE) and Masson trichrome staining were used to observe histopathology changes; E-cadherin and ß-catenin were detected by Immunohistochemical assay, and type â collagen (CollA1) and ß-catenin were detected by immunofluorescent staining. The Wnt/ß-catenin pathway and fibrosis signs were assessed using Western Blot and real-time quantitative polymerase chain reaction (RT-qPCR). RESULTS: The expression of CollA1, Wnt1, and ß-catenin were increased, and E-cadherin, GSK-3ß, and ß-catenin expression were decreased in OSF models. PNS and inhibitor intervention increased E-cadherin, Wnt1, and ß-catenin and decreased CollA1 and GSK-3ß in a dose-dependent manner. CONCLUSION: PNS can improve OSF by inhibiting the Wnt/ß-catenin signal pathway and thus may be used as a potential medicine for the treatment of OSF.

BACKGROUND: Melasma is a common pigmentary disorder among Asian women. The available therapies such as bleaching agents, chemical peeling, laser, and intense pulsed light are not satisfactory or safe. In the search to find a new treatment therapy for melasma, oral administration of tranexamic acid (TA) was studied clinically in Chinese patients. METHODS: The study enrolled 74 patients. Tranexamic acid tablets were prescribed at a dosage of 250 mg twice daily for a therapeutic period of 6 months. All the patients were followed up for more than 6 months after the treatment. The effects of treatment were evaluated by two physicians independently and by the patient based on improvement of pigmentation and reduction in melasma size. These were graded into four levels: excellent, good, fair, and poor. RESULTS: After 6 months of treatment, the effects were graded as follows: excellent (10.8%, 8/74), good (54%, 40/74), fair (31.1%, 23/74), and poor (4.1%, 3/74). Side effects of TA such as gastrointestinal discomfort (5.4%) and hypomenorrhea (8.1%) were observed, but no severe complications were found. The recurrence of melasma was observed in seven cases (9.5%). CONCLUSIONS: Oral administration of TA is an effective and safe therapy for the treatment of melasma.

OBJECTIVE: The 2019 coronavirus disease (COVID-19) has spread to most countries around the world, infecting millions of people and resulting in the pandemic. This presents great challenges for dental professionals. It is necessary to explore preventive measures for COVID-19 in dental treatments. METHODS: In this paper, we outline several measures designed to prevent COVID-19 in dental treatments, such as 3-level pre-examination triage and 2-body temperature tests, 3-level protection for medical personnel, gargling before oral treatment, implementing the 4-hand operation, suctioning saliva during oral treatment, using a rubber dam, and strict enforcement of hand hygiene. These measures include recommendations for medical staff and give practical advice for managing treatment. RESULTS: The epidemic has been brought under control, and routine oral examination and treatments have gradually been resumed from March 9, 2020, in Hunan Province, China. From January 24 to March 8, 2020, a total of 4272 patients received oral therapy during the COVID-19 epidemic in our hospital. We followed these guidelines during the COVID-19 epidemic, and none of the clinical dental staff, other workers, or patients were infected with COVID-19. CONCLUSIONS: These preventive measures for COVID-19 in dental treatments can be used as a reference for oral clinics and stomatological hospitals.

BACKGROUND: The primary presumed advantages of the deep inferior epigastric perforator flap over the other muscle-sparing (MS) transverse rectus abdominis myocutaneous flaps are the improved functional rectus abdominis muscle outcomes and decreased abdominal contour morbidities. The purpose of this study was to verify this viewpoint objectively and quantitatively using an animal model. METHODS: Six rats were used in the pilot study and 40 rats were equally divided into a control group and 4 experimental groups (MS0, MS1, MS2, and MS3) according to the amount of rectus abdominis muscles harvested. At 3 and 6 weeks, 4 rats in each group were killed, then, the percentage of residual rectus abdominis muscle thickness compared with the control side and the ultimate load at failure of the abdominal wall were recorded and compared. RESULTS: All of the flaps survived completely without complications. Regarding the percentage of residual rectus abdominis muscle thickness compared with the control side, the results suggested MS3 > MS2 ≈ MS1 > MS0; concerning the ultimate load at failure of the abdominal wall, the results showed MS3 ≈ MS2 > MS1 > MS0. (≈: P > 0.05; >: P < 0.05). CONCLUSIONS: According to the findings of this study, we advocate the use of the deep inferior epigastric perforator flap when possible, and the MS2-transverse rectus abdominis myocutaneous flap can serve as a backup when the perforator anatomy does not meet the flap safety criteria for preservation of rectus abdominis muscle function.

Keratinocyte proliferation and migration are crucial steps during skin wound healing. The functional role of microRNAs (miRs) remains relatively unknown during this process. miR-93 levels have been reported to increase within 24 h of skin wound healing; however, whether miR-93-3p or miR-93-5p plays a specific role in wound healing is yet to be studied. In this study, with the use of an in vivo mouse skin wound-healing model, we demonstrate that miR-93-3p is significantly upregulated, whereas there is no change in the expression of miR-93-5p during skin wound healing. In HaCaT cells, miR-93-3p overexpression increased proliferation and migration of the cells, whereas miR-93-3p inhibition had the reverse effect. Additionally, it was evident that ZFP36L1 was a direct target of miR-93-3p in keratinocytes. Further, ZFP36L1 silencing mirrored the consequences observed during miR-93-3p overexpression on both proliferation and migration of keratinocytes. In addition, we demonstrate that zinc-finger X-linked (ZFX), as a target for ZFP36L1, is involved in the promotion of the miR-93-3p/ZFP36L1 axis in keratinocyte proliferation and migration. Ultimately, we found that mouse skin wound model treatment with anti-miR-93-3p delayed wound healing. Overall, our results show that miR-93-3p is a crucial regulator of skin wound healing that facilitates keratinocyte proliferation and migration through ZFP36L1/ZFX axis.
RESUMO
OBJECTIVES: This study was performed to review the efficacy of curcumin in the treatment of oral submucous fibrosis systematically. METHODS: We searched seven databases, including Web of Science, PubMed, EBSCO, The Cochrane Library, CNKI, WanFang Data, and VIP, to obtain randomized controlled trials related to the treatment of oral submucous fibrosis by curcumin. Each database was searched from inception to 30 June 2019. RevMan 5.3 software was used for the meta-analysis. RESULTS: Six randomized controlled trials involving 350 patients were included in this study. Meta-analysis showed that curcumin can increase the maximal mouth opening and improve burning sensation compared with placebo treatment. Curcumin was not as effective as the controls in achieving maximal mouth opening after 1 month of treatment. However, no statistically significant difference was observed between the treatments from 2 months to 6 months. Curcumin significantly improved burning sensation compared with the controls after 3 months of treatment. No statistically significant diffe-rence in burning sensation was observed between the curcumin and control groups after 1, 2, and 6 months of treatment. CONCLUSIONS: The current evidence shows that curcumin is an effective treatment for improving maximal mouth opening and burning sensation in patients with oral submucous fibrosis. Given the limited number and low quality of the included studies, however, more high-quality studies are needed to verify these findings.

When a biological public health event breaks out, due to the characteristics of their work, doctors and nurses must face risks directly when the situation is unknown. Their difficulties and psychological pressure are unimaginable. However, few studies have investigated the difficulties encountered by those doctors and nurses and their requirements for psychological interventions. This study aimed to explore the difficulties and psychological intervention needs of doctors and nurses during the new biological public health events in China in 2019. We carried out a qualitative study using a phenomenological approach. We used convenience sampling to identify participants who provided direct care and treatment for patients with biological events such as coronavirus disease 2019 (COVID-19). They participated in semi-structured, in-depth face-to-face interviews. The interviews were transcribed and analyzed using Colaizzi's seven-step method. Analysis of this study was divided into the difficulties encountered by doctors and nurses and their mental health need. The difficulties encountered by doctors and nurses included four themes: being worried about the impact on others, lack of knowledge and skills, difficult patients, being socially isolated, and the feeling of uncertainty. The mental health need was summarized into two parts, needs expressed by doctors and nurses and needs observed by researchers. Doctors and nurses mostly did not feel that they needed any psychological support, but the researchers noticed several signs of stress or potential mental health problems among interviewees. Doctors and nurses faced significant complex and multidimensional difficulties. Many denied needing psychological support, even though the researchers noted signs that it might be helpful. Interventions and support strategies that involve mental health promotion activities should consider individual needs related to doctors and nurses' situation.
RESUMO
BACKGROUND: Studies have shown that manual lymphatic drainage (MLD) has a beneficial effect on lymphedema related to breast cancer surgery. However, whether MLD reduces the risk of lymphedema is still debated. The purpose of this systematic review and meta-analysis was to summarize the current evidence to assess the effectiveness of MLD in preventing and treating lymphedema in patients after breast cancer surgery. METHODS: From inception to May 2019, PubMed, EMBASE, and Cochrane Library databases were systematically searched without language restriction. We included randomized controlled trials (RCTs) that compared the treatment and prevention effect of MLD with a control group on lymphedema in breast cancer patients. A random-effects model was used for all analyses. RESULTS: A total of 17 RCTs involving 1911 patients were included. A meta-analysis of 8 RCTs, including 338 patients, revealed that MLD did not significantly reduce lymphedema compared with the control group (standardized mean difference (SMD): -0.09, 95% confidence interval (CI): [-0.85 to 0.67]). Subgroup analysis was basically consistent with the main analysis according to the research region, the publication year, the sample size, the type of surgery, the statistical analysis method, the mean age, and the intervention time. However, we found that MLD could significantly reduce lymphedema in patients under the age of 60 years (SMD: -1.77, 95% CI: [-2.23 to -1.31]) and an intervention time of 1 month (SMD: -1.77, 95% CI: [-2.23 to -1.30]). Meanwhile, 4 RCTs including, 1364 patients, revealed that MLD could not significantly prevent the risk of lymphedema (risk ratio (RR): 0.61, 95% CI: [0.29-1.26]) for patients having breast cancer surgery. CONCLUSIONS: Overall, this meta-analysis of 12 RCTs showed that MLD cannot significantly reduce or prevent lymphedema in patients after breast cancer surgery. However, well-designed RCTs with a larger sample size are required, especially in patients under the age of 60 years or an intervention time of 1 month.
