RESUMEN

We aimed to evaluate the efficacy and safety of a fractional microneedle radiofrequency device (FMRD) for the treatment of primary axillary hyperhidrosis (PAH). The FMRD adopted insulated microneedles, which could be located at a depth of up to 4.5 mm and deliver a radiofrequency current in a fractional manner. Also, the device could automatically regulate the amount of the delivered energy. Sixteen Korean patients with PAH received two FMRD treatment sessions at a 3-week interval and were followed-up until week 15. The primary outcome was Patient Satisfaction Scale (PSS) score at each visit. Hyperhidrosis Disease Severity Scale (HDSS) and Global Aesthetic Improvement Scale (GAIS) were also assessed. The area and amount of sweat produced were evaluated by specific tests. Mean PSS score significantly improved from 1.6 at week 3 to 2.5 at week 15 by 56%. More than a 50% improvement in sweating assessed by the PSS score was seen in 63% and 50% of patients at weeks 11 and 15, respectively. Mean HDSS score significantly decreased by week 3 and further decreased by week 7. Mean GAIS scores improved from the first follow-up visit at week 3 and improved again at week 7. The mean hyperhidrosis area assessed by starch-iodine test significantly decreased by 36% at week 15 compared with baseline. Mean transepidermal water loss level significantly decreased by 42% at week 15 compared with baseline. No patients experienced any serious adverse events. FMRD can be an effective and safe treatment modality for PAH.

RESUMEN

The long-term effectiveness and safety of hyaluronic acid fillers in mid-face volume restoration in Asians remain unclear. The objective of this study was to compare the long-term effectiveness and safety of Neuramis Volume Lidocaine (SHAPE-NVL) and Juvederm Voluma with Lidocaine (VYC-20L) in mid-face volume restoration in Asians. Overall, 88 Korean subjects with moderate-to-severe age-related mid-face volume deficit on the Mid-Face Volume Deficit Scale (MFVDS) received SHAPE-NVL on one side and VYC-20L on the contralateral side of the face. Of the 81 subjects who completed the 48-week primary study, 69 subjects were enrolled in an extension study lasting 104 weeks. MFVDS score and global aesthetic improvement were assessed at each visit. Response was defined as a ≥1-point reduction in MFVDS. At weeks 36 and 48, the responder rates for SHAPE-NVL were 81.93% and 80.72%, while those for VYC-20L were 85.54% and 81.92%, respectively. At the 104-week visit, the responder rates were 73.91% and 72.46% for SHAPE-NVL and VYC-20L, respectively. No subjects experienced any serious adverse events during the trial. SHAPE-NVL and VYC-20L showed comparable longevity and safety in mid-face volume restoration over 2 years in Asians. Both had durable effects for up to 2 years with minimal safety concerns.

RESUMEN

Fatigue is one of the common symptoms in individuals with diseases or disorders, significantly affecting quality of life (QoL) and the prognosis of diseases. This study aimed to comprehensively compare the features of fatigue across a wide range of diseases. We systematically searched the PubMed and Cochrane Library databases from inception to March 31st, 2021, and conducted a meta-analysis to generate precise estimates. The analyses were stratified by classification of diseases, gender, and severity of fatigue (moderate and severe), and study quality was assessed using the Newcastle-Ottawa Scale (NOS). In total, 214 articles (233 prevalence data) met our eligibility criteria, covering 102,024 participants (mean 438 ± 1,421) across 88 diseases. Among these, seventy-eight data sets (52,082 participants) and thirty-nine data sets (10,389 participants) reported gender- and severity-related fatigue prevalence. The overall prevalence among subjects with 88 diseases was 49.4% [95% CI 46.9-52.1]. According to the International Classification of Diseases-10 (ICD-10) classification, the highest prevalence of fatigue (65.9% [95% CI 54.9-79.6]) was observed in patients with mental/behavioral diseases, whereas the lowest prevalence (34.7% [95% CI 24.5-49.2]) was found among those with circulatory system diseases. A slight female dominance (43.5% vs. 49.8%) was observed in the total data, with the most notable female predominance (1.8-fold) seen in patients with low back pain. The top disease groups with a moderate to severe level of fatigue included gastroparesis (92.3%), pulmonary hypertension (90.0%), chronic obstructive pulmonary disease (COPD, 83.2%), and multiple sclerosis (80.0%). These results are the first to comprehensively show the comparative features of fatigue prevalence among subjects across 88 diseases. Our findings provide valuable reference data for future research on fatigue and for the management of patients with fatigue.Prospero registration number: CRD42021270494.

RESUMEN

Background: Fatigue is one of the most common subjective symptoms that impairs daily life and predict health-related events. This study aimed to estimate the prevalence of fatigue in the global population. Methods: PubMed and the Cochrane Library were used to search for relevant articles from inception to December 31, 2021. Studies with prevalence data of fatigue in the general population were selected and reviewed by three authors independently and cross-checked. Regarding subgroups, adults (≥18 years), minors (<18 years), and specific occupation population (participants in each study being limited to a specific occupational group), and fatigue types and severity, meta-analysis was conducted to produce point estimates and 95% confidence intervals (95% CI). Results: From the initial 3,432 studies, 91 studies accounting for 115 prevalence data points (623,624 participants) were finally selected. The prevalence of general fatigue (fatigue lasting < 6 months, or fatigue of unspecified duration) was 20.4% (95% CI, 16.7-25.0) in adults, 11.7% (95% CI, 5.2-26.6) in minors, and 42.3% (95% CI, 33.0-54.2) in specific occupations. Chronic fatigue (fatigue lasting more than 6 months) affected 10.1% (95% CI, 8.2-12.5) of adults, 1.5% (95% CI, 0.5-4.7) of minors, and 5.5% (95% CI, 1.4-21.6) of subjects in specific occupations. There was an overall female-predominant prevalence for all subgroup analyses, with a total odds ratio of 1.4 (95% CI, 1.3-1.6). Regarding the severity and presence of medical causes, the total prevalence of moderate fatigue [14.6% (95% CI, 9.8-21.8)] was 2.4-fold that of severe fatigue [6.1% (95% CI, 3.4-11.0)], while unexplained fatigue (fatigue experienced by individuals without any underlying medical condition that can explain the fatigue) was ~2.7-fold that of explained fatigue (fatigue experienced by individuals with a medical condition that can explain the fatigue); as proportion of 40.0% of physical, 8.6% of mental, and 28.4% of mixed cause. Conclusions: This study has produced the first comprehensive picture of global fatigue prevalence in the general population, which will provide vital reference data contributing to fatigue-related research, including the prevention of diseases.

RESUMEN

Cancer-related fatigue (CRF) affects therapeutic compliance and clinical outcomes including recurrence and mortality. This study aimed to comprehensively and comparatively assess the severity-based prevalence of CRF. From two public databases (PubMed and Cochrane Library), we extracted data containing information on both prevalence and severity of fatigue in cancer patients through December 2021. We conducted a meta-analysis to produce point estimates using random effects models. Subgroup analyses were used to assess the prevalence and severity by the organ/system tumor development, treatment phase, therapeutic type, sex and assessment method. A total of 151 data (57 studies, 34,310 participants, 11,805 males and 22,505 females) were selected, which indicated 43.0% (95% CI 39.2-47.2) of fatigue prevalence. The total CRF prevalence including 'mild' level of fatigue was 70.7% (95% CI 60.6-83.3 from 37 data). The prevalence of 'severe' fatigue significantly varied by organ/system types of cancer origin (highest in brain tumors 39.7% vs. lowest in gynecologic tumors 3.9%) and treatment phase likely 15.9% (95% CI 8.1-31.3) before treatment, 33.8% (95% CI 27.7-41.2) ongoing treatment, and 24.1% (95% CI 18.6-31.2) after treatment. Chemotherapy (33.1%) induced approximately 1.5-fold higher prevalence for 'severe' CRF than surgery (22.0%) and radiotherapy (24.2%). The self-reported data for 'severe' CRF was 20-fold higher than those assessed by physicians (23.6% vs. 1.6%). Female patients exhibited a 1.4-fold higher prevalence of 'severe' fatigue compared to males. The present data showed quantitative feature of the prevalence and severity of CRF based on the cancer- or treatment-related factors, sex, and perspective of patient versus physician. In the context of the medical impact of CRF, our results provide a comparative reference to oncologists or health care providers making patient-specific decision.

RESUMEN

An advanced intermediate: A nonheme iron(IV) oxo complex [Fe(IV)(O)(bqen)(L)](n+) (bqen = N,N'-dimethyl-N,N'-bis(8-quinolyl)ethane-1,2-diamine, L = CH(3)CN or CF(3)SO(3)(-)) activates the C-H bonds of alkanes and alcohols by a hydrogen-atom abstraction mechanism. The catalytic oxidation of these species is proposed to occur through a nonheme iron(V) oxo species, with a high reactivity in oxidation reactions (see picture).

RESUMEN

Invasion and metastasis are the major causes of treatment failure in patients with cancer. Here, we investigated the effects of ginsenoside Rh1 on tumor invasion and metastasis in human hepatocellular carcinoma HepG2 cells and its possible mechanism of action. Rh1 showed concentration- and time-dependent inhibition of HepG2 cell migration and invasion. Matrix metalloproteinase-1 (MMP-1) gene expression and its promoter activity were also concentration-dependently inhibited by Rh1 treatment. The inhibitory effect of Rh1 on MMP-1 expression was due to inactivation of the mitogen-activated protein kinases (MAPKs) ERK, JNK, and p38 MAPK. By transient transfection analysis with the MMP-1 promoter (-2846 to -29 nt) and AP-1 promoter, MMP-1 and AP-1 promoter activities were induced by phorbol myristate acetate (PMA) but were significantly inhibited by PD98059 (ERK1/2 inhibitor) or SP600125 (JNK inhibitor). The induction of MMP-1 and AP-1 promoters by PMA was attenuated by Rh1, and both promoter activities were synergistically inhibited by co-treatment with PD98059. To evaluate the effects of Rh1 on AP-1 dimers, expression analysis and electrophoretic mobility shift (EMSA) assay using radiolabeled AP-1-specific oligomers at proximal site (-73 nt) and distal site (-1600 nt) of the MMP-1 promoter were performed. The results showed that Rh1 inhibited the expression of c-Jun and c-Fos but did not affect the DNA binding ability of AP-1-specific oligomers. However, Rh1 attenuated the stability of c-Jun. Therefore, Rh1 has potential for development of novel chemotherapeutic agents for treatment of malignant cancers, including early hepatocellular carcinoma related to MMP-1 expression.

RESUMEN

Ginsenoside Rd is a protopanaxadiol-type ginsenoside found in ginseng and is the active ingredient in several Oriental herbal medicines. We investigated the effects of ginsenoside Rd on tumor invasion and metastasis in the human hepatocellular carcinoma HepG2 and its possible mechanism of action. HepG2 cells were treated with ginsenoside Rd at different concentrations. Scratch wound and Boyden chamber assays were used to determine the effects of ginsenoside Rd on the migration and invasiveness of HepG2 cells, respectively. The molecular mechanisms by which ginsenoside Rd inhibited the invasion and migration of HepG2 cells were investigated by RT-PCR, Western blotting, gelatin zymography, promoter assay, and treatment with inhibitors of MAPK signaling. Immunofluorescence analysis was conducted to evaluate the effect of ginsenoside Rd on focal adhesion formation in HepG2 cells. Treatment with ginsenoside Rd dose- and time-dependently inhibited the migration and invasion of HepG2 cells. It achieved this by reducing the expression of MMP-1, MMP-2, and MMP-7, by blocking MAPK signaling by inhibiting the phosphorylation of ERK and p38 MAPK, by inhibition of AP-1 activation, and by inducing focal adhesion formation and modulating vinculin localization and expression. Treatment of HepG2 cells with ginsenoside Rd significantly inhibited metastasis, most likely by blocking MMP activation and MAPK signaling pathways involved in cancer cell migration. These findings may be useful for the development of novel chemotherapeutic agents for the treatment of malignant cancers.

RESUMEN

We investigated the effect of caffeoylserotonin (CaS) on THP-1 monocyte migration and adhesion to fibronectin in response to MCP-1. CaS decreased monocyte adhesion and migration induced by MCP-1, together with CCR2 expression and α5ß1 integrin, and activated ß1 integrin expression on the cell surface. CaS also inhibited FAK and Akt phosphorylation. We found that CaS had anti-inflammatory activity based on inhibition of adhesion and migration via inhibition of the integrin ß1/FAK/Akt signalling pathway. Thus, the inhibitory effects of CaS on monocyte function may support the future development of this compound as a potential treatment for inflammation-dependent diseases.

RESUMEN

Ginsenoside Rh1 has been reported to possess antiallergic and anti-inflammatory activities, but its effects on monocytes remain to be determined. Herein, we investigated the effects of Rh1 on the expression of MCP-1 and CCR2, activation of MAPK signaling, and chemotaxis of monocytes. Treatment of Rh1 decreased the levels of MCP-1 and CCR2 and the expression of VLA5 and activated ß1 integrin on the cell surface, and attenuated the phosphorylation of MAPKs. Based on these results, the inhibitory effects of Rh1 on monocyte function should be regarded as a promising new anti-inflammatory response with a potential therapeutic role against inflammation-dependent diseases.
