Sustained antimicrobial activity and reduced toxicity of oxidative biocides through biodegradable microparticles

The spread of antibiotic-resistant pathogens requires new treatments. Small molecule precursor compounds that produce oxidative biocides with well-established antimicrobial properties could provide a range of new therapeutic products to combat resistant infections. The aim of this study was to investigate a novel biomaterials-based approach for the manufacture, targeted delivery and controlled release of a peroxygen donor (sodium percarbonate) combined with an acetyl donor (tetraacetylethylenediamine) to deliver local antimicrobial activity via a dynamic equilibrium mixture of hydrogen peroxide and peracetic acid. Entrapment of the pre-cursor compounds into hierarchically structured degradable microparticles was achieved using an innovative dry manufacturing process involving thermally induced phase separation (TIPS) that circumvented compound decomposition associated with conventional microparticle manufacture. The microparticles provided controlled release of hydrogen peroxide and peracetic acid that led to rapid and sustained killing of multiple drug-resistant organisms (methicillin-resistant Staphylococcus aureus and carbapenem-resistant Escherichia coli) without associated cytotoxicity in vitro nor intracutaneous reactivity in vivo. The results from this study demonstrate for the first time that microparticles loaded with acetyl and peroxygen donors retain their antimicrobial activity whilst eliciting no host toxicity. In doing so, it overcomes the detrimental effects that have prevented oxidative biocides from being used as alternatives to conventional antibiotics

The analgesic efficacy of ultrasound-guided transversus abdominis plane block vs. local anesthetic infiltration technique in major gynecologic surgery: A randomized controlled trial

Background and aim: Transversus abdominis plane (TAP) block and local anesthetic infiltration (LAI) technique are used as part of the multimodal analgesic regimen after abdominal surgery. Postoperative opioid consumption and analgesic efficacy was compared using TAP and LAI techniques in patients undergoing gynecologic surgery in a randomized, controlled clinical trial.Material and methods: Total of 135 patients scheduled for major gynecological surgeries were allocated into three groups: group T received bilateral TAP block with bupivacaine 0.25%; group I received LAI with 0.25% bupivacaine with epinephrine 5 μ/mL in the peritoneum and abdominal wall, and group C was control group. Anesthesia and postoperative analgesia were standardized. Outcome measures were cumulative and rescue tramadol consumption, numerical rating score (NRS) for pain and side effects in post-anesthesia care unit (PACU) at 4, 8, 12 hours postoperatively.Results: Tramadol consumption, need for rescue analgesia, and NRS for pain between three groups at 4, 8, and 12 hours postoperatively had no statistically significant difference (P \u3c 0.05). In PACU, median tramadol consumption used for rescue analgesia between group T (15 (15-30)) and group C (30 (15-45)) (P = 0.035), and between group T (15 (15-30)) and group I (30 (15-52)) was statistically significant (P = 0.034). In PACU, the percentage of patients having NRS \u3e4 on movement in group C (72%) compared to group T (46.5%) and group I (46.5%) was significant (P = 0.034). No statistically significant difference was observed in the incidence of side effects among study groups (P \u3e 0.05).Conclusion: Except for the immediate postoperative period, neither TAP block nor LAI had added benefit to the multimodal analgesia regimen in patients undergoing gynecological surgeries

Effect of microneedling by dermaroller on acne scars: an observational study at tertiary care hospital

Background: Post acne facial scar is very distressing phenomenon. There are many treatment options like laser resurfacing, dermabrasion, microdermabrasion and non-ablative laser resurfacing but it may cause adverse effects and interference with the daily activities of the patient. Microneedling or dermaroller therapy is newer modality in management of acne scars with satisfactory improvement and no significant side effect. Objective of our study was to evaluate efficacy and safety of microneedling in the treatment of atrophic facial acne scars. Methods: Twenty-eight patients of Fitzpatrick skin type IV to V having atrophic facial acne scars and fulfilling inclusion criteria were treated with multiple sittings of microneedling (dermaroller) treatment at monthly interval. Goodman and Baron’s qualitative and quantitative acne scar grading system was used for assessment. Patients were evaluated clinically and by serial photography. Presence of any active infection, active acne, wounds, blisters, keloids, taking some medications like Accutane, antihypertensives, anticoagulants, systemic retinoids, topical retinoids, those undergoing cosmetic procedures, treatment with injecting fillers or ablative or non-ablative laser resurfacing, diabetes, collagen diseases and those who do not agree to participate in study were excluded. Results: Any change in the grading of scars after the end of treatment and follow-up period was noted. Efficacy and improvement of dermaroller treatment was assessed by Goodman and Baron’s global acne scarring system. Out of 18 patients (of total 28) with Goodman and Baron’s qualitative grade-4, 16 (88.90%) patients reduced to grade-1. 21 out of 28 patients achieved ‘excellent’ response. Adverse effects were limited to transient erythema and post inflammatory hyperpigmentation. Conclusions: Microneedling therapy seems to be simple, safe and efficacious for the management of atrophic facial acne scars

Improving Diagnosis and Clinical Management of Acquired Systemic Autoinflammatory Diseases

Systemic autoinflammatory diseases (SAID) are conditions caused by dysregulation or disturbance of the innate immune system, with neutrophils and macrophages the main effector cells. Although there are now more than 40 distinct, genetically defined SAIDs, the genetic/molecular diagnosis remains unknown for a significant proportion of patients with the disease onset in adulthood. This review focuses on new developments related to acquired/late onset SAID, including phenocopies of monogenic disorders, Schnitzler’s syndrome, Adult onset Still’s disease, VEXAS syndrome, and autoinflammatory complications associated with myelodysplastic syndrome

Trends in the lifetime risk of developing cancer in Great Britain: comparison of risk for those born from 1930 to 1960

BACKGROUND: Typically, lifetime risk is calculated by the period method using current risks at different ages. Here, we estimate the probability of being diagnosed with cancer for individuals born in a given year, by estimating future risks as the cohort ages. METHODS: We estimated the lifetime risk of cancer in Britain separately for men and women born in each year from 1930 to 1960. We projected rates of all cancers (excluding non-melanoma skin cancer) and of all cancer deaths forwards using a flexible age-period-cohort model and backwards using age-specific extrapolation. The sensitivity of the estimated lifetime risk to the method of projection was explored. RESULTS: The lifetime risk of cancer increased from 38.5% for men born in 1930 to 53.5% for men born in 1960. For women it increased from 36.7 to 47.5%. Results are robust to different models for projections of cancer rates. CONCLUSIONS: The lifetime risk of cancer for people born since 1960 is >50%. Over half of people who are currently adults under the age of 65 years will be diagnosed with cancer at some point in their lifetime

Raman Spectroscopy Study of alpha-, beta-, gamma-NaxCoO2 and gamma-(Ca,Sr)xCoO2

Raman spectroscopy measurements have been performed on alpha-, beta-, gamma-NaxCoO2 phases differing in their stacking of CoO6 octahedra along the c-axis direction. The results demonstrate that, in general, there are five active phonons for gamma-Na0.75CoO2, two Raman active phonons for alpha-NaCoO2, and four Raman active phonons for beta-NaCoO2. We have also performed Raman scattering measurements on several gamma-(Ca,Sr)xCoO2 (0.15 <= x <= 0.35) samples which show well-defined intercalated Ca/Sr-ordering. The experimental data show that the intercalated cation ordering could result in visible alterations on Raman spectral structures. The observations of the spectral changes along with the variation of the CoO6 stacking, as well as the intercalated Sr/Ca ordering suggest that the interlayer interaction plays an important role for understanding the lattice dynamics in this layered system.Comment: 23 pages, 5 figures, Physical Review B, in pres
