Transcutaneous lower eyelid blepharoplasty with micro-autologous fat transplantation harvested from orbital fat pads for lower eyelid aging treatment.

The aging process of lower eyelids results in lower eyelid wrinkles, tear troughs, and eye bags. Many therapies have been described for treatment of lower eyelid aging, and transcutaneous blepharoplasty is often used for treating cases with eyebags and dermatochalasis. However, it may cause depression near the medial orbit resulting in a hollowed look. In the present study, we developed an innovative method transferring the herniated fatty tissue to volume loss area during the surgical procedure of transcutaneous lower eyelid blepharoplasty by means of micro-autologous fat transplantation harvested from resected orbital fat pads. Besides, we also analyze it efficacy and safety compared with traditional methods of transcutaneous lower eyelid blepharoplasty. We reviewed the records of the patients who underwent transcutaneous lower eyelid blepharoplasty with and without micro-autologous fat transplantation, for lower eyelid aging improvement. We used global aesthetic improvement scale, Hirmand's classification system, and Wrinkle Severity Rating Scale to evaluate the cosmetic outcome at 1 week, 1 month, and 3 months after operation by two independent investigators. We found patients received transcutaneous lower eyelid blepharoplasty with autologous fat graft had significantly higher global aesthetic improvement scale and Wrinkle Severity Rating Scale improvement than those underwent transcutaneous lower eyelid blepharoplasty only in each evaluation timepoints. There was no significant difference of adverse effects between both surgical methods. The present study demonstrated the efficacy and safety of the lower eyelid blepharoplasty with micro-autologous fat transplantation harvesting from resected orbital fat pads.

Risks of Glaucoma among Individuals with Psoriasis: A Population-based Cohort Study.

BACKGROUND: Psoriasis is a chronic systemic disorder with ocular involvement. OBJECTIVES: The aim of the present study is to evaluate the risk of glaucoma among psoriatic patients. METHODS: Subjects of this cohort study were selected based on Chang Gung Research Database from January 1, 2003, to December 31, 2012. Follow-up ended on December 31, 2017. The participants of the control group were matched with the psoriatic group by gender, age, and index date at a 4:1 ratio. The hazard ratios of glaucoma were estimated using Cox regression analysis. We also evaluated the relationship between the risk of glaucoma and systemic therapies as well as phototherapy and topical corticosteroid in patients with psoriasis. RESULTS: A total of 6,682 patients with psoriasis and 26,728 matched controls were enrolled. The study population is composed of mainly Males accounting for 64.2% of the study population. The psoriatic group had higher incidence rates than the control group for glaucoma (adjusted hazard ratio 1.405 [95% confidence interval, 1.051-1.879]). Psoriatic patients receiving psoralen and ultraviolet-A (PUVA) therapy for more than 200 sessions had an increased risk of glaucoma. CONCLUSIONS: Psoriatic patients had an increased risk of glaucoma. Long-term PUVA therapy raised the risk of glaucoma in psoriatic populations.

The Effects of Negative Pressure Therapy on Hair Growth of Mouse Models.

Negative pressure therapy (NPT) has been shown to facilitate wound healing and promote hair growth in a porcine model. However, there is a paucity of research on the impact of negative pressure on hair growth in murine models. Despite the ability of nude mice to develop hair follicles, the hair they produce is often flawed towing to genetically induced keratin disorders, rendering them a pertinent animal model for assessing hair regeneration. Therefore, this study aims to investigate the effects of negative pressure on hair follicle growth in a nude mouse model. To achieve this, a customized external tissue expansion device was developed to apply negative pressure to the dorsum of nude mice. The mice were subjected to several treatment courses consisting of 15 and 30 min of continuous negative pressure at 10 mmHg, which were repeated 5 and 10 times every other day until sacrifice. Dorsal skin samples were subsequently extracted from the suction and nonsuction areas. The sections were stained with various antibodies to assess the expression of SOX-9, LHX-2, Keratin-15, ß-catenin, CD31, and vascular endothelial growth factor-A, and a TUNEL assay was used to analyze cell apoptosis. The results showed that the number of hair follicles and angiogenesis were significantly higher in the suction area than in the nonsuction area in all groups. Moreover, mice that received NPT for 15 min for 10 times had a higher hair follicle density than the other three groups. Immunofluorescence staining for LHX-2 and Keratin 15 further validated the results of these findings. In conclusion, this study demonstrated that negative pressure effectively promotes hair follicle growth and angiogenesis in nude mice through SOX-9- and LHX-2-mediated follicular regeneration and ß-catenin-mediated hair follicle morphogenesis.

Major adverse cardiovascular events in advanced-stage lung cancer: a multicenter cohort study.

Background: Lung cancers are common worldwide. First-line targeted therapy and chemotherapy are both standard treatments in the current guidelines. With the development of new anticancer therapy, the lifespan of patients with late-stage lung cancer has increased. Cardiovascular events can occur during cancer treatment. This observational study aimed to report the incidence of major adverse cardiovascular events (MACE) after cancer treatment using real-world data. Objectives: Patients diagnosed with advanced-stage lung cancer between January 2011 and December 2017 were enrolled. Data were collected from the Chang Gung Research Database (CGRD). Design: Retrospective cohort study. Methods: Baseline characteristics, clinical stages, pathologies, and outcomes were retrieved from the CGRD. Results: We identified 4406 patients with advanced lung cancer, of whom 2197 received first-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) therapy and 2209 received first-line platinum-based chemotherapy. Most patients in the first-line EGFR-TKI group were never-smokers (74.9%), whereas those in the first-line chemotherapy group were ever-smokers (66.0%). The incidence of MACE was not significantly different between the two groups (12.0% versus 11.9%, p = 0.910). However, the incidence of ischemic stroke was higher in the first-line EGFR-TKI group than in the first-line chemotherapy group (3.9% versus 1.9%, p < 0.001). Conclusion: MACEs are common in patients with advanced-stage lung cancer during treatment. The incidence of MACE was similar between the first-line EGFR-TKI therapy and first-line chemotherapy groups. Although more patients in the EGFR-TKI group were female and never-smokers, the risk of ischemic stroke was higher in patients who received first-line EGFR-TKI therapy than in those who received first-line chemotherapy.

Platelet-Rich Plasma Versus Platelet-Poor Plasma for Treating Facial Photoaging: a Double-Blind Randomized Controlled Splitting Face Study.

BACKGROUND: As the demand for non-invasive esthetic procedures to maintain a youthful appearance increases, there has been growing interest in the use of autologous platelet-rich plasma (PRP) and platelet-poor plasma (PPP) for the treatment of facial aging. However, there are few studies directly comparing the efficacy of PRP and PPP for facial rejuvenation. OBJECTIVES: This study aimed to compare the efficacy of PRP and PPP for facial rejuvenation. METHODS: This single-center, double-blind, randomized controlled trial was conducted from January 1, 2022, to July 31, 2022, and included ten participants who completed the follow-up. The participants were randomly assigned to receive 2.5-mL injections of PRP and PPP on different sides of the face in three sessions with 1-month intervals. The outcome was primarily determined by blinded photographic assessments and secondly by scores of the VISIA® system during the follow-up. RESULTS: Both PRP and PPP treatments resulted in significant improvement in the Global Aesthetic Improvement Scales and Modified Fitzpatrick Wrinkle Scale for periocular Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation wrinkles, with no significant difference between the two groups. However, no improvement was observed in the Wrinkle Severity Rating Scales for nasolabial folds in either the PRP- or PPP-treated groups. Furthermore, no severe adverse events were reported. CONCLUSIONS: Both PRP and PPP are effective in treating facial photoaging. PRP exhibited slightly superior efficacy in enhancing overall skin condition, while PPP was slightly more effective in improving shallow wrinkles. This study provides valuable evidence for the use of PRP and PPP in facial rejuvenation procedures.

A structured approach with Swiss cheese model to reduce vascular adverse events of filler injections.

BACKGROUND: Filler injection is among the most popular nonsurgical aesthetic procedures worldwide. Though relatively noninvasive, filler injection can lead to severe vascular adverse events. Even though the incidence is rare, it may cause devastating and irreversible outcomes. A Swiss cheese model has been widely applied for risk analysis and management approach in medical field. AIMS: In this review article, we adopt the Swiss cheese model and create a structured approach to prevent severe vascular complications caused by filler injections. METHODS: We reviewed the current literature regarding the knowledge and techniques of preventing vascular adverse events in the filler injection. RESULTS: We propose four structured strategies in this model to reduce the risk of severe vascular adverse events of filler injections, including clinical facial anatomy, safe filler injection principles, real time imaging and auxiliary instruments, and implication of checklist. CONCLUSION: This review provides clinicians a structured approach before and during the filler injection procedure to reduce the risk of vascular adverse events and improve its safety and outcome.

Risk of osteoporosis among individuals with varicose veins: a multi-institution cohort study.

The present study showed a significant association between varicose veins and the development of osteoporosis, especially women and patients older than 50 years. Physicians should be alerted to this issue and consider screening for osteoporosis in patients with varicose veins. PURPOSE: Osteoporosis might be associated with many skin diseases. However, only a paucity of data addressing the association between varicose veins and subsequent osteoporosis development. The study was aimed to evaluate whether there is an increased risk of osteoporosis among patients with varicose veins. METHODS: This multi-institution database study was based on Chang Gung Research Database from January 1, 2003, to December 31, 2015. Patients aged 20 years and older with varicose veins were enrolled. Participants in the control group were selected by matching in a 4:1 ratio by sex, age, index date, and comorbidities. The hazard ratios associated with osteoporosis were estimated using Cox regression analysis with competitive risk model. Incidence rate of osteoporosis was assessed in individuals with and without varicose veins. RESULTS: A total of 11,959 patients with varicose veins and 47,633 matched controls were enrolled in the study. The varicose veins group had higher incidence rates than the control group for osteoporosis (46.40 vs 31.92 per 10,000 person-years; adjusted HR 1.481 [95%CI, 1.314-1.669; P < 0.001]). Compared with matched controls, varicose veins patients with or without venous ulcers had 1.711- and 1.443-times increased risk of developing osteoporosis, respectively. Subgroup analysis showed varicose veins were associated with osteoporosis in women and patients older than 50 years. CONCLUSION: The present study demonstrated individuals with varicose veins had an increased risk of osteoporosis. Physicians should be alerted to this issue and consider screening for osteoporosis in patients with varicose veins, especially among women and patients older than 50 years.

Association Between Magnitude of Differential Blood Pressure Reduction and Secondary Stroke Prevention: A Meta-analysis and Meta-Regression.

Importance: The degree to which more intensive blood pressure reduction is better than less intensive for secondary stroke prevention has not been delineated. Objective: To perform a standard meta-analysis and a meta-regression of randomized clinical trials to evaluate the association of magnitude of differential blood pressure reduction and recurrent stroke in patients with stroke or transient ischemic attack (TIA). Data Sources: PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched from January 1, 1980, to June 30, 2022. Study Selection: Randomized clinical trials that compared more intensive vs less intensive blood pressure lowering and recorded the outcome of recurrent stroke in patients with stroke or TIA. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was used for abstracting data and assessing data quality and validity. Risk ratio (RR) with 95% CI was used as a measure of the association of more intensive vs less intensive blood pressure lowering with primary and secondary outcomes. The univariate meta-regression analyses were conducted to evaluate a possible moderating effect of magnitude of differential systolic blood pressure (SBP) and diastolic blood pressure (DBP) reduction on the recurrent stroke and major cardiovascular events. Main Outcomes and Measures: The primary outcome was recurrent stroke and the lead secondary outcome was major cardiovascular events. Results: Ten randomized clinical trials comprising 40 710 patients (13 752 women [34%]; mean age, 65 years) with stroke or TIA were included for analysis. The mean duration of follow-up was 2.8 years (range, 1-4 years). Pooled results showed that more intensive treatment compared with less intensive was associated with a reduced risk of recurrent stroke in patients with stroke or TIA (absolute risk, 8.4% vs 10.1%; RR, 0.83; 95% CI, 0.78-0.88). Meta-regression showed that the magnitude of differential SBP and DBP reduction was associated with a lower risk of recurrent stroke in patients with stroke or TIA in a log-linear fashion (SBP: regression slope, -0.06; 95% CI, -0.08 to -0.03; DBP: regression slope, -0.17; 95% CI, -0.26 to -0.08). Similar results were found in the association between differential blood pressure lowering and major cardiovascular events. Conclusions and Relevance: More intensive blood pressure-lowering therapy might be associated with a reduced risk of recurrent stroke and major cardiovascular events. These results might support the use of more intensive blood pressure reduction for secondary prevention in patients with stroke or TIA.

A single session of high-energy microwave axillary hyperhidrosis and osmidrosis therapy: Key pretherapeutic assessment and outcome analysis.

BACKGROUND: Microwave therapy is used to treat axillary hyperhidrosis and osmidrosis. Even while a "danger zone" has been identified and reports of potential complications from nerve injury have been made, there has been little real-world discussion regarding whether there is any pretreatment evaluation key factor that may lower the risk. Furthermore, the efficacy of a single treatment and the safety of high-energy therapies have not been well investigated. OBJECTIVE: The aim of this study is to demonstrate the key aspects of pre-therapeutic assessment, efficacy, and suitability of a single treatment, as well as the safety of high-energy treatments. METHODS: Fifteen patients with axillary hyperhidrosis (AH) and axillary osmidrosis (AO) between ages of 20 and 50 had pretherapeutic ultrasonography and clinical assessments performed followed by a single-pass microwave treatment using the miraDry system at energy level 5. The severity of AH and AO was evaluated using the Hyperhidrosis Disease Severity Scale and Odor-10 scale, respectively, at baseline, 1 month, 3 months, and 1 year after treatment. Adverse reactions were recorded at each point of evaluation. RESULTS: Out of 30 treatment areas, 14 have a danger zone. Female gender, a small mid-upper arm circumference, and a low body mass index (BMI) are all associated risk factors. The average Hyperhidrosis Disease Severity Scale score decreased from 3.1 ± 0.7 to 1.3 ± 0.5 (p < 0.001), while the odor-10 score declined from 7.1 ± 1.6 to 3.0 ± 1.6 (p < 0.001), indicating a significant improvement in AH and AO. Most of the unfavorable treatment effects disappeared within the first month. LIMITATIONS: This study has no objective quantitative measurement of axillary odor severity and sweat assessment. CONCLUSION: Female patients, those with a smaller mid-upper arm circumference, and those with a low BMI should be treated with extra caution, and the tumescent anesthetic dose may be increased based on safety. A high-energy microwave treatment procedure performed in a single session is a safe and effective therapeutic option with good recovery.
