Hepatocyte-Specific Co-Delivery of Zinc Ions and Plasmid DNA by Lactosylated Poly(1-vinylimidazole) for Suppression of Insulin Receptor Internalization

The lactosylated poly(1-vinylimidazole) (PVIm-Lac) with various lactosylated degrees has been synthesized for the co-delivery of zinc ions (Zn) and plasmid DNA (pDNA). The Zn/DNA/PVIm-Lac complex formation has achieved the specific delivery of zinc ions to HepG2 cells. Especially, the resulting hepatocyte-specific delivery of zinc ions has increased the number of insulin receptors on the cell surface. Consequently, the Zn/DNA/PVIm-Lac complexes have suppressed insulin receptor internalization on the surface of the HepG2 cells, expecting to offer unique therapy to inhibit hepatic insulin clearance.

Biodebridement in the Surgical Intensive Care Unit: Unique Therapy for Unique Patients

Acute care surgery has evolved to encompass the advanced management of complex nonhealing wounds. Biodebridement has the potential to improve the care of chronic wounds for acute care surgery patients, particularly for patients in the surgical intensive care unit (SICU) with hospital-acquired pressure injuries. A case report of biodebridement using larval maggot therapy in the SICU is presented to illustrate real-world application and progression in wound healing. A review of current research involving biodebridement was conducted. A septuagenarian gentleman sustained a fall resulting in cervical spine fractures with neurological deficits. The patient had a prolonged hospital course in the SICU, complicated by myocardial infarction, respiratory failure requiring tracheostomy, and development of a Stage IV sacral pressure ulcer. The wound base was sharply debrided several times and became refractory to conventional mechanical/chemical debridement techniques. The patient had a prohibitively high risk for the operating room but remained too sensate for further effective bedside debridement. Biodebridement was utilized to create a viable wound base, with improved appearance noted within 2 weeks. A review of the current literature shows biodebridement has numerous benefits in the management of chronic wounds. Biodebridement is a unique therapy that possesses great value for select patients in the SICU. In particular, patients who are too high risk for further operative intervention, but too sensate for ongoing bedside debridement and dressing changes, benefit significantly from this underutilized approach. Further research is needed to solidify the place of biodebridement in the surgical management of chronic nonhealing wounds.

NP213 (Novexatin®): A unique therapy candidate for onychomycosis with a differentiated safety and efficacy profile

NP213 (Novexatin®) is a novel antifungal peptide specifically designed for the topical treatment of onychomycosis. NP213 was designed using host defense peptides (HDP), essential components of the innate immune response to infection, as a template. NP213 is a water-soluble cyclic fungicidal peptide that effectively penetrates human nail. NP213 demonstrated a promising preclinical and clinical safety profile, with no evidence of systemic exposure following topical application to the skin and nails. NP213 was efficacious in two phase IIa human trials with 43.3% of patients having no fungi detectable by culture of fragments from NP213-treated nails after 180 days in the first study and likewise 56.5% of patients were culture negative for dermatophytes after 360 days in the second phase IIa study. In both trials, NP213 was applied daily for only 28 days in marked contrast to other topical onychomycosis treatments that require application for up to 52 weeks. Patient reported outcomes from the phase IIa studies were positive with participants recording an improved appearance of their nails after only 14 days of application. All fungi identified in these studies were Trichophyton spp. NP213 (Novexatin®) is a promising, highly differentiated peptide-based candidate for the topical treatment of onychomycosis, addressing the infectious cause and cosmetic issues of this very common condition.

Basic and clinical application progression of invigorating blood and dissolving stasis Chinese medicine in ophthalmology

Invigorating blood and dissolving stasis method is a kind of unique therapy of traditional Chinese medicine treatment, which efficacy has become increasingly prominent in the treatment of ophthalmology, with the further studies of blood stasis and invigorating blood and dissolving stasis therapy, it is widely used in clinical ophthalmology, and get good effects beyond thought, especially when western medicine has no curative effects, which improve the cure rate of fundus oculi disease from the eyelids, conjunctiva, lacrimal sac, vitreous body to the choroid and retina, optic nerve and macula lutea, from surface to fundus. Pathological changes related to inflammation, degeneration, necrosis, atrophy, hyperplasia of fibrous tissue hyperplasia. This paper is aim to explain the definition of invigorating blood and dissolving stasis and make a summary of basic research and clinical application about it in several diseases.

Use of the International Classification of Functioning, Disability and Health in Speech-Language-Hearing Therapy: an integrative literature review

ABSTRACT Purpose: to carry out an integrative review of literature regarding the use of the ICF in Speech-Language-Hearing Therapy. Methods: a search was conducted on both national and international databases, for articles published between 2008 and 2018, considering the following descriptors in Portuguese, English and Spanish: “International Classification of Functioning, Disability and Health”, “Speech-Language-Hearing”, and “Speech Therapy”. Duplicated articles, as well as those introducing new ICF-based protocols and studies whose theme didn’t refer exclusively to speech-language-hearing practices were excluded. Results: 36 articles were found, 9 of which met the inclusion criteria. The articles were categorized according to speech-language-hearing subareas (most belonging to the subarea of language), and to types of study (most being case studies). Conclusion: studies point out that the ICF can contribute to the development of unique therapy projects in a broader approach to health in the speech-language-hearing clinic. However, it has been perceived the need for more researches on the theme with applicability to the other fields of knowledge in speech-language-hearing sciences.

Acute uncomplicated cystitis: is antibiotic unavoidable?

Background: Acute uncomplicated cystitis in women is one of the most frequently diagnosed bacterial infections. Methods: In a pilot, open, noncomparative prospective study, 29 nonpregnant, sexually active women with acute uncomplicated cystitis were enrolled. The mean age was 28.9 ± 4.3, range 22–36 years. All patients received unique therapy: the nonsteroidal anti-inflammatory drug (NSAID) ketoprofen, 100 mg once a day for 5 days, and Canephron, 2 dragees three times a day for 1 month. Results: In 2 days, four patients (13.8%) had no tendency to improvement; they were considered as nonresponders and antibiotics were prescribed for them. The remaining 25 patients (86.2%) showed significant improvement and were considered as responders; they continued the therapy with ketoprofen and Canephron. In 7 days, 21 patients (72.4%) had no dysuria and leucocyturia; they were considered as fast responders to phytotherapy. In four patients (13.8%), after 7 days of therapy insignificant dysuria and leucocyturia were found; they were considered as slow responders to phytotherapy. All 25 patients continued the intake of Canephron for 1 month to prevent a relapse. When treatment finished, all patients were well. In 6 months, no relapses were diagnosed. Conclusion: The majority (86.2%) of young, nonpregnant women with acute uncomplicated cystitis were cured by 30 days of phytotherapy combined initially (5 days) with the NSAID ketoprofen; an antibiotic was indicated in only 13.8% of patients. Patients with acute uncomplicated cystitis may be divided into three subgroup: nonresponders to phytotherapy; slow responders to phytotherapy; fast responders to phytotherapy. Antibiotic therapy is indicated in nonresponders, but slow and fast responders may be treated without an antibiotic, by phytotherapy with an initial short course of an NSAID only.

Split-Belt Treadmill Walking Alters Lower Extremity Frontal Plane Mechanics

Interventions that manipulate gait speed may also affect the control of frontal plane mechanics. Expanding the current knowledge of frontal plane adaptations during split-belt treadmill walking could advance our understanding of the influence of asymmetries in gait speed on frontal plane mechanics and provide insight into the breadth of adaptations required by split-belt walking (SBW). Thirteen young, healthy participants, free from lower extremity injury walked on a split-belt treadmill with belts moving simultaneously at different speeds. We examined frontal plane mechanics of the ankle, knee, and hip joints during SBW, as well as medio-lateral ground reaction forces (ML-GRF). We did not observe alterations in the frontal mechanics produced during early or late adaptation of SBW when compared to conditions where the belts moved together. We did observe that ML-GRF and hip moment impulse of the fast limb increased over time with adaptation to SBW. These results suggest this modality may provide a unique therapy for individuals with gait pathologies, impairments, or compensation(s).
