Vocal fold atrophy and scar can lead to loss of normal superficial lamina propria, negatively affecting the vibratory function of the vocal fold. These changes can lead to dysphonia, vocal fatigue, decreased volume, and altered pitch. Treatment options for these conditions are limited. Platelet-rich plasma (PRP) consists of platelets, growth factors, and cytokines derived from the patient's own blood and is believed to activate tissue regeneration. The purpose of this study was to review the technical aspects of collecting PRP and injecting it into the vocal fold injection - based on our initial experience with this procedure. A patient with vocal fold scar was identified and enrolled in an ongoing prospective clinical trial study of a series of 4 monthly subepithelial vocal fold PRP injections, which was temporarily halted due to the COVID-19 pandemic. Patient underwent a single injection of autologous PRP into the left vocal fold. There were no adverse events during the study period. Subjective improvemphy and scar. This work highlights the technical considerations for injecting PRP into the vocal fold. Planned prospective enrollment in this study will help to validate the safety and efficacy of PRP injections. To analyse the patient-nurse ratio and its association with health outcomes in public hospitals of the Andalusian Health Service (SAS). Cross-sectional ecological study carried out in adult units of 26 Andalusian public hospitals. Data on structure (beds, type of unit, nursing control), management (average stay, index of use of stays, complexity index) and nursing staff were collected. They were extracted from official sources CMBDA, SAS/Health Council (CS) publications and specific respondents to Nursing Directorates. The patient-nurse ratio was calculated and related to 19 indicators of hospital quality, safety, and mortality. Measures of central tendency and Spearman's correlation coefficient were used for statistical analysis. A response was obtained from 100% of the Andalusian hospitals. The average patient-nurse ratio in the three shifts was lower in hospitals with a broader portfolio of services-regional scope (11.6), followed by those with a medium portfolio-specialties (12.7) and hospitals with a basic portfolio- county (13.5). By type of unit, the medical units were 11.8 (SD=1.8) lower than the surgical ones 13.5 (SD=2.7). Significant differences were only found in medical units of regional hospitals 10.5 (SD=1.4) and district hospitals 13.03 (SD=1.46) (p=.001). In critical care, the ratio was greater than 2 patients per nurse in the three groups. When relating the ratio to health outcomes, 5 significant associations were found pressure ulcers (p=.005), prevalence of nosocomial infections (p=.036), postoperative sepsis (p=.022), zero bacteraemia verification (p=.045) and mortality from heart failure (p=.004). The results indicate a high patient-nurse ratio in adult hospitalization units and that there is a positive association between the patient-nurse ratio and worse results related to nursing care.

This study aimed to perform the first meta-analysis of studies comparing transcarotid (TC) and trans-subclavian (TSc) transcatheter aortic valve replacement (TAVR). The safety and feasibility of a TC and a TSc approach for performing TAVR in patients with prohibitive femoral anatomy have been well described. The potential advantage of one approach over the other is yet to be ascertained. A computerized literature search of key medical databases through September 2020 was performed. https://www.selleckchem.com/products/gdc6036.html Randomized controlled trials (RCTs) and observational studies comparing TC and TSc TAVR with reported 30-day outcomes were considered. The primary endpoint was a composite of all-cause mortality, stroke, life-threatening, and/or major bleeding or major vascular complications. Statistical analysis using random-effects models to report the odds ratio (OR) with 95% confidence interval (CI) was performed. A total of 5 observational studies inclusive of 4164 patients (TC=1788 and TSc=2376) met the eligibility criteria. The average age of patients was 81.1years. There was no difference in the occurrence of the composite endpoint between the groups at 30-days. A statistically insignificant trend towards higher rates of major vascular complications (OR 1.65; 95% CI 0.94-2.89; P=0.08; I =0%) and the need for permanent pacemaker placement was observed with the TSc approach. This meta-analysis of studies comparing TC and TSc TAVR showed similar 30-day outcomes between the 2 approaches. A notable trend towards higher rates of major vascular complications and the need for permanent pacemaker placement was observed with the TSc approach.

The ideal drug-eluting stent (DES) for the treatment of unprotected left main coronary artery (ULMCA) is unknown. We compared percutaneous coronary intervention (PCI) using durable polymers versus early-generation, thicker strutted and coated bioabsorbable polymers for ULMCA disease. Patients who underwent ULMCA PCI (893 patients) from April 2008 to November 2014 were identified from the Grand-DES registry. The primary end point was 3-year target lesion failure (TLF) after propensity score matching. The final analysis included 754 patients (84.4%) and 139 patients (15.6%) in the durable and bioabsorbable polymer group, respectively. The groups differed significantly in lesion and procedural characteristics. Propensity score-matched analysis revealed a trend toward a lower 3-year TLF in the durable polymer group (log rank p=0.071). Independent predictors of 3-year TLF were chronic kidney disease, presentation with acute myocardial infarction, and a two-stenting technique for ULMCA lesions. Definite/probable stent thrombosis rates at 3-years were low in both groups (0.
