Safety and aesthetic evaluation of autologous dermal fat grafts for lateral Skull base defect reconstruction

ObjectiveThe selection of appropriate materials and techniques for reconstructing skull base defects is crucial for restoring function, minimizing complications, and enhancing aesthetics. Dermal fat grafts (DFGs) have been established in many surgeries for contour correction. However, there is little literature describing the application of free dermal fat grafts for reconstruction of lateral skull base surgery defects. Therefore, the aim of this study was to evaluate the clinical effect of using free dermal fat grafts in the reconstruction of lateral skull base defects.MethodsIn this study, 32 patients who underwent primary autologous free dermal fat graft reconstruction for lateral skull base defects were enrolled. Postoperative complications both in the donor and recipient area were evaluated. Three-dimensional (3D) reconstruction techniques were applied to visualize the fat graft shape and volume variations for the assessment of postoperative restoring function. A telephone questionnaire was used for the assessment of postoperative facial aesthetics and patient satisfaction.ResultsA total of 32 patients who met the inclusion criteria were included in the study, showing satisfying results in safety and aesthetics. Participants’ ages averaged at 42.03 years, with the youngest being 18 and the oldest at 75 years old. No patient had postoperative complications of abdominal wounds in the donor area, only two patients had postoperative infections and one patient had a postoperative effusion in the recipient area. The volume of the grafts ranged from a minimum of 24.4 cm³ to a maximum of 131 cm³, with the highest recorded resorption volume being 33.63 cm³. The average resorption rate of the dermal fat graft was 24.36%, ranging from a minimum of 11% to a maximum of 43%. 3D reconstruction based on MRI imaging data indicated that DFGs have a lower resorption rate than traditional free fat grafts. The telephone questionnaire revealed high patient satisfaction with facial aesthetics, with the majority rating their outcomes positively.ConclusionsDermal fat grafts have fewer complication and can provide better resistance to infection and radiation aspect. Based on 3D reconstruction techniques via MRI imaging data, we found that dermal fat grafts have lower resorption rate than traditional free fat grafts, which can be a suitable material for reconstruction of lateral skull base defects.

Addressing Hypertension and Diabetes through Community-Engaged Systems (ANDES) in Puno, Peru: rationale and study protocol for a hybrid type 2 effectiveness and implementation randomized controlled trial

BackgroundHypertension is the most common cardiovascular disease in Peru despite the availability of cost-effective, evidence-based treatment. Here we describe the rationale and study design for a hybrid type 2 randomized controlled trial to test the implementation and effectiveness of a community health worker (CHW)-led hypertension control program within the national primary care system in Puno, Peru.MethodsWe will recruit 1068 adult participants with hypertension aged ≥ 18 years in Puno, Peru, via facility-based enrollment and community health fairs. Participants will be individually randomized (1:1) to either continue with usual care or participate in a 12-month CHW-led home-based hypertension control program consisting of blood pressure monitoring, medication adherence support, and healthy lifestyle counseling. Outcome development and reporting are guided by the Consolidated Framework for Implementation Research (CFIR), the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, and the Proctor et al. framework. Clinical effectiveness outcomes include mean change in systolic blood pressure (primary outcome), diastolic blood pressure, and HbA1C. Implementation outcomes include fidelity (i.e., CHW protocol adherence and dose), reach, adoption, sustainability, acceptability, and cost-effectiveness.DiscussionThe ANDES trial is testing the first CHW-led multicomponent strategy for hypertension and type 2 diabetes management in Peru. This type 2 hybrid trial will provide critical insights into the individual, community, and system-level factors necessary for successful implementation and effectiveness. These data can inform the future adaptation and scaling of the ANDES strategy in Peru and other LMICs, as well as influence policies at the system level to support this transition. Furthermore, by addressing both hypertension and diabetes, the ANDES strategy supports integrated care approaches advocated by the WHO HEARTS technical package, ultimately enhancing health outcomes and reducing morbidity and mortality in the region.Trial registrationClinicalTrials.gov, ID: NCT05524987, Addressing Hypertension and Diabetes through Community-Engaged Systems in Puno, Peru (ANDES study), prospectively registered on September 1, 2021.

The impact of acupuncture on the brain function of patients with mild to moderate major depressive disorder: a randomized controlled trial protocol

IntroductionMajor depressive disorder (MDD) is a common mental disease that significantly impact the daily lives of those affected. Acupuncture has shown promising therapeutic effects in the treatment of MDD, but its underlying mechanisms remain unclear. This study aims to evaluate the influence of acupuncture on the brain function of patients with MDD and it’s therapeutic effects on MDD.MethodsThis study plans to recruit 112 participants, who will be randomly allocated to either the acupuncture group or the sham acupuncture group in a 1:1 ratio. Both groups will undergo 8 weeks of treatment, consisting of three sessions per week, with each session lasting for 30 min. A follow-up period of 3 months will be conducted after the treatment. Assessments will be conducted at weeks 0, 8, 12, 16, and 20 in this study. The primary outcome measure will be functional near-infrared spectroscopy (fNIRS) brain imaging, while secondary outcome measures will include Beck Depression Inventory II (BDI-II), Self-Rating Anxiety Scale (SAS), 36-Item Short Form Survey Instrument (SF-36), Traditional Chinese Medicine (TCM) syndrome score scale, and symptom elimination rate.DiscussionWhile acupuncture has been confirmed to have a certain degree of therapeutic efficacy in the treatment of MDD, research on the mechanisms underlying acupuncture’s treatment of MDD remains limited, particularly with regards to its impact on the brain function of individuals with MDD. This study aims to explore both the clinical effectiveness and treatment mechanisms of acupuncture for MDD, with a specific focus on its influence on brain function. This research endeavors to provide new insights into the potential of acupuncture as a therapeutic approach for the treatment of MDD in the future.Trial Registrationwww.chictr.org.cn, ID: ChiCTR2300076292.

The effectiveness of deep learning model in differentiating benign and malignant pulmonary nodules on spiral CT

BACKGROUND: Pulmonary nodule, one of the most common clinical phenomena, is an irregular circular lesion with a diameter of ⩽ 3 cm in the lungs, which can be classified as benign or malignant. Differentiating benign and malignant pulmonary nodules has an essential effect on clinical medical diagnosis. OBJECTIVE: To explore the clinical value and diagnostic effects of the lung nodule classification and segmentation algorithm based on deep learning in differentiating benign and malignant pulmonary nodules. METHODS: A deep learning model with a fine-grained classification manner for the discrimination of pulmonary models in Dr.Wise Lung Analyzer. This study retrospectively enrolled 120 patients with pulmonary nodules detected by chest spiral CT from March 2021 to September 2022 in the radiology department of Ninghai First Hospital. The DL-based method and physicians’ accuracy, sensitivity, and specificity results were compared using the pathological results as the gold standard. The ROC curve of the deep learning model was plotted, and the AUCs were calculated. RESULTS: On 120 CT images, pathologically diagnosed 81 malignant nodules and 122 benign modules. The AUCs of radiologists’ diagnostic approach and DL-base method for differentiating patients were 0.62 and 0.81; radiologists’ diagnostic approach and DL-base method achieved AUCs of 0.75 and 0.90 for benign and malignant pulmonary nodules differentiate. The accuracy, sensitivity, and specificity with the deep learning model were 73.33%, 78.75%, and 62.50%, respectively, while the accuracy, sensitivity, and specificity with the physician’s diagnosis were 63.33%, 66.25%, and 57.500. CONCLUSION: There was no significant difference between the diagnosis results of the proposed DL-based method and the radiologists’ diagnostic approach in differentiating benign and malignant lung nodules on spiral CT (P< 0.05).

Extracorporeal Shock Wave Therapy (ESWT) vs. Exercise in Thumb Osteoarthritis (SWEX-TO): Prospective Clinical Trial at 6 Months

Rhizarthrosis is the most frequent form of osteoarthritis and is responsible for pain, disability and reduced functionality. The aim of the study is to investigate the clinical effects of shock wave treatment in patients suffering from arthritis of the first finger. A prospective clinical study was designed, in which 72 patients affected by rhizarthrosis were randomized to treatment with shock waves or exercises; in both groups an immobilization brace was used on the first finger. At recruitment and at 1, 3 and 6 months, patients received assessments of pain (VAS), functionality (FIHOA) and disability (DASH); furthermore, the perception of improvement was monitored during follow-ups (Roles and Maudsley Score). In both groups there was a significant improvement in all scores in the comparison between recruitment and 6 months. The perception of improvement was statistically better in the shock wave group than in the exercise group at 1, 3 and 6 months. The regression analysis showed that the reduction of VAS and DASH were statistically influenced by shock wave treatment (p < 0.001). Both therapies are effective in managing patients suffering from arthritis of the first finger, but the shock wave treatment could ensure greater persistence of improvements.

Comparison of the effectiveness of drug therapy and non-drug technology of post-COVID rehabilitation of workers with intensive computer load

Currently, there is sufficient evidence of the importance and clinical effectiveness of non-drug therapy. The scientific discussion on the priority of the clinical application of pharmacological and non-pharmacological methods of rehabilitation of patients with mononeuropathies has acquired particular importance against the background of neurological post-COVID complications in patients with COVID-19. The study aims to compare the effectiveness of drug therapy and non–drug technology of post-covid rehabilitation of workers with intensive computer workload based on the study of clinical and laboratory parameters. Scientists have conducted a survey of two groups of workers with intensive computer workload who underwent rehabilitation after COVID-19 with the use of drug therapy and non-drug technologies, including balneotherapy, drinking narcotherapy, aerosol inhalations, low-frequency magnetic therapy. The authors have evaluated the effectiveness of therapy based on the results of studies of asthenization, degree of fatigue, latent coronary insufficiency, the state of the blood microcirculation system, immune status, the state of the POL-AOSIS system and endogenous intoxication of patients. Asthenization, the degree of fatigue, and latent coronary insufficiency decreased in the majority of the examined patients after post-COVID non-drug measures. Whereas in patients of the drug group, a decrease in these indicators was noted in a small number of examined patients. The indicators of the immune status of patients after non-drug therapy returned to normal, after drug therapy they only approached the limits of the norm, but did not reach it. After the treatment, the indicators of lipid peroxidation in the group of patients undergoing post-COVID rehabilitation using non-drug technologies decreased more significantly than in the group receiving drug treatment. The content of the antioxidant enzymes catalase and ceruloplasmin and the fat-soluble antioxidant α-tocopherol after treatment increases in both groups, but in the group of drug treatment they do not reach the lower limit of the reference intervals. The decrease in the content of medium-molecular peptides is more pronounced when using non-drug technologies. The application of the proposed non-drug technology for the rehabilitation of patients with post-COVID syndrome who are subjected to intense computer loads during work showed a significantly more pronounced normalization of asthenization, fatigue, latent coronary insufficiency and the state of the blood microcirculation system, immune status, the state of the POL-AOSIS system and endogenous intoxication of patients. The data obtained indicate a high therapeutic effect of the use of non-drug technology. Limitations. The surveyed groups included only persons permanently registered in Kislovodsk. Ethics. The research was conducted in accordance with the principles of biomedical ethics and approved by the local Ethics Committee of the Izmerov Research Institute of Occupation Health, Moscow (Protocol No. 4 dated 04/14/2021). Each participant of the study submitted a voluntary written informed consent signed by him after explaining to him the potential risks and benefits.

A modified intensive, comprehensive aphasia program (mICAP) has better reported outcomes than usual care: a randomized controlled trial

ABSTRACT Background Intensive Comprehensive Aphasia Programs (ICAPs) are a new model of service delivery that show promising pre-post outcomes but have yet to be compared with usual care. Aim To compare the clinical effectiveness of a modified Intensive Comprehensive Aphasia Program (mICAP) to usual care in a parallel two arm study utilizing stratified block randomisation. Methods & Procedures Participants were a referred sample with post stroke aphasia from ten local speech pathology departments. Assessments were completed prior to, immediately after, and follow up at 3 months after the mICAP. While 269 participants with aphasia were approached for the study, only 52 were eligible to be randomised with 113 participants approached not meeting selection criteria and 99 of eligible participants declining to participate. Block randomization was based on matched moderate/mild versus severe aphasia pairs. Three of the 26 mICAP participants withdrew. In the experimental arm of the mICAP (the LIFT program), participants with aphasia and their family attended goal directed tailored therapy three times weekly for 8 weeks. Therapy included 14 hours each of impairment therapy, functional communication therapy, and computer therapy and 7 hours of group therapy and a challenge task. The main outcome measures were the self-reported Assessment for Living with Aphasia (ALA) and Content Information Units (#CIU’s) in connected speech. Outcomes & Results Linear Mixed Modelling was completed on the remaining 42 participants’ data and found a significant benefit for the mICAP on the ALA Total score (p= .014; 95% CI= −21.48- −2.57) ALA Aphasia domain (p = .027; 95% CI= −3.23 - −0.203), ALA Environment domain (p = .017; 95% CI= −4.70 - −0.493) immediately post intervention with maintenance of effects for the ALA Aphasia domain in the follow up period (p = .014; 95% CI= −3.64 - −0.438). Family members in the mICAP reported significant reduction in caregiving burden in the follow up period (p= .017; CI= −14.12 - −1.52.). There were no significant differences on the other main outcome measure of Content Information Units (95% CI= −34.94 – 55.15). Conclusions For those suitable and interested, the mICAP was more beneficial than usual care for participants with aphasia and their family members. However, lack of significant differences in discourse and other language functions, suggests that individual elements of mICAPs and their evaluation require review. Based on these results, the LIFT program has been refined to become the Comprehensive High-dose Aphasia Therapy (CHAT) program.

Clinical effects of anweiyang capsule and Pinellia decoction for eradication of Helicobacter pylori and healing of peptic ulcers

Peptic ulcers are a prevalent and often chronic condition within the digestive system, frequently prone to recurrence. This study aims to evaluate the clinical effects of Anweiyang capsule combined with Pinellia Heart-Draining Decoction on Helicobacter pylori eradication, ulcer healing rates, and improvement of Traditional Chinese Medicine (TCM) syndromes in patients with peptic ulcers. A total of 100 patients were randomly assigned to an observation group (n = 50), receiving the herbal combination, and a control group (n = 50), receiving standard Western medical treatment. The total effective rate was significantly (P < 0.05) higher in the observation group (96%) compared to the control group (80%). After 4 weeks of treatment, serum procalcitonin (PCT) and C-reactive protein (CRP) levels decreased, while prostaglandin E2 (PGE2) levels increased in both groups; however, the observation group exhibited better results (P < 0.05). The observation group achieved a H. pylori eradication rate of 94% and an ulcer healing rate of 82%, compared to 64% and 56% in the control group, respectively. Improvement in TCM syndrome scores was more significant in the observation group (P < 0.05). Moreover, the incidence of adverse reactions was significantly (P < 0.05) lower in the observation group (4%) compared to the control group (18%). In conclusion, Anweiyang capsule combined with Pinellia Heart-Draining Decoction significantly enhances the eradication rate of H. pylori and the ulcer healing rate without substantially increasing the risk of adverse reactions, demonstrating its safety and reliability for patients.

Simultaneous reconstruction of tibial osteomyelitis-complicated soft tissue defects using free flap transplantation in conjunction with the masquelet technique: a retrospective study

ObjectiveTo investigate the clinical effect of anterolateral femoral free flap combined with Masquelet technique in the treatment of tibial osteomyelitis with wound surface.MethodsA retrospective study was conducted to analyze the clinical data of 25 patients with tibial osteomyelitis combined with defected wounds in Xijing Hospital of Fourth Military Medical University from Jun 2017 to Oct 2021. After one-stage treatment with free flap combined with Masquelet technique, the infection index, lower extremity function score (LEFS), and Mazur ankle function score were compared before bone defect repair and at the last follow-up.ResultsThe anterolateral femoral free flaps of 25 patients in phase I survived. The healing time of bone fracture after stage II operation was 8–12 months [(7.2 ± 0.9) months]. At the last follow-up, the infection index was significantly lower than that before bone defect repair (P < 0.01). The LEFS and Mazur ankle function scores [(56.2 ± 7.9) and (78.2 ± 16.1)] of the affected limb were significantly higher than those before bone defect repair [(26.0 ± 8.6) and (44.7 ± 18.2)] (P < 0.01). Wounds of all patients’ legs healed well, without complications (foot drop, joint dysfunction, or deformity in the affected limbs).ConclusionThe anterolateral femoral free flap combined with Masquelet technique is an effective treatment strategy for tibial osteomyelitis combined with soft tissue defects. This technology can effectively repair limb trauma, inhibit infection, and improve flexion and extension functions of knee and ankle joint.

Implementing palliative care in hepatocellular carcinoma ambulatory clinics—study protocol for Accelerated translational research in PRImary liver CAncer (APRICA) randomised controlled palliative care trial

BackgroundIntegration of symptom and palliative care for people with advanced cancer is established in many tumour types, but its role in people with hepatocellular carcinoma (HCC) has not been clearly defined. This study aims to evaluate the clinical and cost effectiveness of an intervention involving a suite of strategies designed to assess and treat palliative care symptoms and needs in adult outpatients with HCC attending four New South Wales (NSW) metropolitan tertiary hospitals.MethodsThis trial will use a pragmatic cluster-based randomised-controlled design, with ambulatory HCC services as the clusters. HCC patients will be recruited if they have Barcelona Clinical Liver Cancer (BCLC) stage A disease with active tumour or a current or prior diagnosis of BCLC stage B or C disease regardless of tumour activity. Patients with BCLC stage D disease will be excluded as palliative care is the standard of care (SOC) in this group. Cluster sites will be randomised to the study intervention or control where patients are managed according to SOC. All participants will complete the liver-specific Edmonton Symptom Assessment Scale (ESAS) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire at regular ambulatory clinic appointments. At intervention sites, patients scoring ≥ 5 on any liver-specific ESAS symptom will be referred to palliative care physicians for consultation. The primary clinical outcome will be improvement in all symptoms scored ≥ 5 on the liver-specific ESAS by 50% within 3 months and the primary implementation outcome will recording the liver-specific ESAS in ≥ 80% of all participants attending clinic appointments. Caregivers of patients enrolled in the trial will be invited to perform Carer Support Needs Assessment Tool at each appointment.DiscussionThis trial will inform if earlier palliative care involvement significantly reduces the symptom burden associated with HCC. If found to be effective, earlier implementation of palliative care consultation should be included in HCC treatment guidelines.Trial registrationACTRN12623000010695.

A visual laryngoscope combined with a fiberoptic bronchoscope improves intubation outcomes in patients with predicted difficult airways in thoracic surgery

ObjectiveTo study the clinical effectiveness of visual laryngoscopy combined with fiberoptic bronchoscopy-guided double-lumen endotracheal tube intubation in thoracic surgery patients with predicted difficult airways in thoracic surgery airways.MethodsWe randomly divided 162 patients with predicted difficult airways who required double-lumen tracheal intubation for thoracic surgery and randomly divided them into the video laryngoscopy group (Group VL, n = 54),fiberoptic bronchoscopy group (Group F, n = 54), and video laryngoscopy combined with fiberoptic bronchoscopy group (Group FVL, n = 54) according to the randomized number table method. Then, the success rate of the first intubation, the duration of intubation, the duration of positioning, the degree of exposure of the vocal cords (Cormack-Lehane grade), and the adverse reactions during intubation were recorded and analyzed.ResultsThe success rate of first-time intubation was significantly higher in the FVL group than in the F and VL groups (92.6% vs. 87.0% vs. 53.7%, P < 0.001), and the time of intubation in the FVL group was significantly shorter than that in the VL and F groups [(26.22 ± 9.34) s vs. (42.35 ± 11.21) s vs. (46.78 ± 21.96) s, P < 0.001)]. The positioning time in the FVL group was significantly shorter than that in the F and VL groups [(83.76 ± 15.18) s vs. (102.72 ± 21.89) s vs. (145.41 ± 20.12) s, F = 144.896, P < 0.001)].The number of patients with Cormack-Lehane grades I-II was significantly lower in the FVL group and the VL group than in the F group (88.9% vs. 77.8% vs. 59.3%, P < 0.05).The incidence of postoperative sore throat was significantly lower in the FVL group and the F group than in the VL group (22.4% vs. 27.6% vs. 50%, P < 0.001).ConclusionIn difficult airway patients with high airway risk indices who require double-lumen endotracheal intubation, visual laryngoscopy combined with fiberoptic bronchoscopy improved the success rate of first-time intubation and shortened the intubation and positioning time.Trial registrationChinese Clinical Trial Register (identifier: ChiCTR2300076304; Date of registration: September 29, 2023).

Evaluation and Analysis of the Clinical Effects of Laparoscopic Surgery for Pediatric Direct Inguinal Hernia.

Objective: To assess both the clinical effectiveness and practical experience of utilizing laparoscopic methods for addressing direct inguinal hernia in the pediatric population. Method: The study collected clinical data from 10 pediatric patients with direct inguinal hernia treated at the Children's Hospital of Anhui Province from July 2014 to July 2023. Among them, there were 8 males and 2 females, with an average age of 43.4 ± 22.0 months. All were initially diagnosed with indirect inguinal hernia before surgery. During the laparoscopic procedures, direct hernia was confirmed. Two cases had undergone open hernial sac high ligation surgery due to misdiagnosis as indirect hernia, resulting in recurrent groin bulges postoperatively. For these cases, laparoscopic direct hernia neck ligation with reinforcement and repair using the inner side of the umbilical ligament was performed. Results: All 10 cases of pediatric patients underwent surgeries smoothly without any need for open conversion. The average surgical duration was 29.8 ± 15.0 minutes, with minimal intraoperative bleeding. Patients were discharged on the first day postoperatively, and no significant surgery-related complications were observed. During the 12-month follow-up period, it was noted that the scar at the umbilical ring was superficial and inconspicuous. There were no occurrences of hernia recurrence, testicular retraction, or atrophy. Conclusion: Laparoscopic treatment for pediatric direct inguinal hernia has demonstrated favorable therapeutic outcomes, ensuring a safe surgical process, rapid recovery, and a low postoperative recurrence rate. The laparoscopic approach, specifically utilizing direct hernia neck ligation with reinforcement and repair using the inner side of the umbilical ligament, proves to be a secure and effective treatment for pediatric direct inguinal hernia. It can be considered as a conventional treatment method.

Encapsulation of Rifampicin in Solid Lipid Nanoparticles by Microwave‐Assisted Microemulsion Method

AbstractRifampicin (RF) is a potent antibiotic, but its clinical effectiveness is limited by poor water solubility and stability. To overcome these limitations, RF is encapsulated in solid‐lipid nanoparticles (SLNs) using a one‐pot microwave microemulsion method. This study aimed to synthesize and characterize RF‐loaded SLNs, evaluating their physicochemical characteristics and antimicrobial efficacy. The synthesized SLNs exhibit particle sizes ranging from 150 to 200 nm, with a high encapsulation efficiency of ≈55% and high loading capacity. The particles are imaged by cryogenic‐transmission electron microscopy and found to be circular and elongated, with RF homogenously distributed throughout the particles. The RF‐loaded SLNs demonstrate potent antimicrobial activity, as evidenced by disc diffusion assays. The SLNs exhibits a sustained drug release profile, highlighting their potential as an effective drug delivery system for antimicrobial treatment. These findings suggest that SLNs can enhance the stability, bioavailability, and therapeutic efficacy of hydrophobic drugs like RF.

Identifying the quality markers and optimizing the processing of Gastrodiae rhizoma to treat brain diseases

BackgroundGastrodiae rhizoma (GR) refers to the dried tuber of Gastrodia elata Bl. and has been used for many centuries to treat brain diseases, such as Alzheimer’s disease, major depressive disorder, and cerebral ischemia. However, the processing of GR is complex and varied, resulting in unstable clinical treatment effects. The processing protocols significantly affect the active ingredients and curative effects of GR. We can optimize the processing of GR by identifying quality markers to treat brain diseases.MethodsFresh tubers of G. elata Bl. were processed under eight different protocols, and their resulting contents of potentially bioactive compounds were compared using liquid chromatography mass spectrometry to screen the potential quality markers of GR through stoichiometric analysis. The potential quality markers of GR targeting Alzheimer’s disease, major depressive disorder, and cerebral ischemia were identified by network pharmacology, and the potentially neuroprotective effects of these components were validated through simulated docking to likely protein targets. Finally, a fit degree analysis was carried out using different composition ratios and proportions of the disease component degree value, and the therapeutic effects of different processing methods on Alzheimer’s disease, major depressive disorder, and cerebral ischemia were outlined clearly.ResultsWe identified 32 potential therapeutic components and screened 13 quality markers in GR, of which five quality markers (galactinol, glucosyringic acid, parishins C and E, and S-(4-hydroxybenzyl)-glutathione) showed efficacy against all three brain diseases. Furthermore, steaming and microwave-drying during processing can optimize the components of these quality markers for treating the three diseases.ConclusionProcessing protocols significantly affect the therapeutic components of GR and may also impact its effectiveness in treating brain diseases. Accordingly, optimizing the processing methods of GR to correspond to different therapeutic purposes may improve its efficacy against brain diseases.

Comparative study on pregnancy complications: PGT-A vs. IVF-ET with gender-specific outcomes

The safety and clinical effectiveness of preimplantation genetic testing for aneuploidy (PGT-A) in improving pregnancy outcomes for sub-fertile patients remains controversial. Potential sex-based differences in the relationship between PGT-A and pregnancy complications have not been investigated, which could guide the appropriate clinical application of PGT-A. In this secondary analysis of data from a multicenter, randomized, controlled, non-inferiority trial (NCT03118141), 940 women who achieved singleton live birth during the trial were included to estimate the between-group differences in pregnancy complications following PGT-A versus conventional in vitro fertilization (IVF) vary with fetal sex. Logistic regression analysis was used to adjust for possible confounders, and subgroup analysis was also performed. Among male fetuses, the risk of maternal preeclampsia was significantly lower after PGT-A compared to conventional IVF treatment (3.37% vs. 7.88%; adjusted OR, 0.40; 95% CI, 0.17-0.92; P = 0.032). However, this protective effect was not observed in pregnancies with female fetuses (3.63% vs. 3.38%; adjusted OR, 1.04; 95% CI, 0.36-3.00; P = 0.937). In addition, no significant sex-dependent differences in the risks of other pregnancy complications or neonatal outcomes were detected between PGT-A and conventional IVF groups (P &amp;gt; 0.05). In summary, PGT-A was associated with a decreased risk of maternal preeclampsia in singleton pregnancies with male fetuses, highlighting its potential utility in preeclampsia prevention in addition to spontaneous abortion rate reduction.

Brodalumab is Effective for Psoriasis Patients with Difficult-to-treat Body Regions: Results from an Observational Clinical Study.

Brodalumab, a human monoclonal antibody that selectively inhibits the interleukin (IL)-17 receptor subunit A, has been approved for the treatment of moderate-to-severe plaque psoriasis. The treatment benefit of brodalumab has been clearly demonstrated in multiple clinical studies. However, data on effectiveness for difficult-to-treat body regions, especially in everyday clinical practice, are still limited. In this exploratory observational clinical study, psoriasis patients suffering from nail and scalp involvement who received brodalumab during routine clinical care were enrolled at 7 centers in Germany. Patients were observed over 60 weeks. The co-primary endpoints were 75% improvement in Psoriasis Scalp Severity Index (PSSI75) at week 12 and 75% improvement in Nail Psoriasis Severity Index (NAPSI75) at week 24. Secondary endpoints included assessment of general skin and disease outcomes, quality-of-life, and patient satisfaction with treatment. Eighty-seven patients were included. Mean age was 46.8 years, 70.1% patients were male, and mean body mass index was 28.9 kg/m². The co-primary endpoints were achieved by more than 90% of patients who met criteria for effectiveness analyses (n=62): 93.6% of patients achieved PSSI75 at week 12 and 90.3% of patients achieved NAPSI75 at week 24. Median body surface area involvement improved from 14% at baseline to 1.5% and 1% at weeks 12 and 24, respectively. Median Dermatology Life Quality Index scores improved from 16 at baseline to 2 and 1 at weeks 12 and 24, respectively. Improvements were maintained in the majority of patients throughout the 60-week study. Brodalumab was well tolerated and patients were highly satisfied with treatment. Outcomes assessed in this study, including assessments of scalp and nail symptoms, improved following initiation of brodalumab therapy. This study of psoriasis patients in a real-world setting supports the long-term clinical effectiveness of brodalumab on difficult-to-treat body regions.
