Visual and Hearing Impairment Are Associated With Delirium in Hospitalized Patients: Results of a Multisite Prevalence Study

ObjectiveSensory deficits are important risk factors for delirium but have been investigated in single-center studies and single clinical settings. This multicenter study aims to evaluate the association between hearing and visual impairment or bi-sensory impairment (visual and hearing impairment) and delirium.DesignCross-sectional study nested in the 2017 “Delirium Day” project.Setting and ParticipantsPatients 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes, and hospices in Italy.MethodsDelirium was assessed with the 4AT (a short tool for delirium assessment) and sensory deficits with a clinical evaluation. We assessed the association between delirium, hearing and visual impairment in multivariable logistic regression models, adjusting for: Model 1, we included predisposing factors for delirium (ie, dementia, weight loss and autonomy in the activities of daily living); Model 2, we added to Model 1 variables, which could be considered precipitating factors for delirium (ie, psychoactive drugs and urinary catheters).ResultsA total of 3038 patients were included; delirium prevalence was 25%. Patients with delirium had a higher prevalence of hearing impairment (30.5% vs 18%; P < .001), visual impairment (24.2% vs 15.7%; P < .01) and bi-sensory impairment (16.2% vs 7.5%) compared with those without delirium. In the multivariable logistic regression analysis, the presence of bi-sensory impairment was associated with delirium in Model 1 [odds ratio (OR) 1.5, confidence interval (CI) 1.2–2.1; P = .00] and in Model 2 (OR 1.4; CI 1.1–1.9; P = .02), whereas the presence of visual and hearing impairment alone was not associated with delirium either in Model 1 (OR 0.8; CI 0.6–1.2, P = .36; OR 1.1; CI 0.8–1.4; P = .42) or in Model 2 (OR 0.8, CI 0.6–1.2, P = .27; OR 1.1, CI 0.8–1.4, P = .63).Conclusions and implicationsOur findings support the importance of routine screening and specific interventions by a multidisciplinary team to implement optimal management of sensory impairments and hence prevention and the management of the patients with delirium.     

Indigenous Birth as Ceremony and a Human Right

Birthing can be an empowering experience for women. Within many Indigenous cultures around the world, birth is a ceremony to celebrate new life, acknowledging the passing from the spiritual world into the physical world. While initiatives to “indigenize” health care have been made, this paper argues that the United Nations Declaration on the Rights of Indigenous Peoples and the United Nations Sustainable Development Goals contain frameworks for Indigenous rights that include the right to incorporate Indigenous childbirth ceremonies into clinical practice. Examining the importance of birthplace, this paper details a current movement in Manitoba, Canada, to “bring birth home,” which recognizes that the determinants of health experienced in the early stages of a child’s development can have health implications for an individual’s future.

Microencapsulation of human spermatozoa increases membrane stability and DNA longevity

The microencapsulation of spermatozoa offers potential benefits for maintaining sperm survival in vitro. The technique has also resulted in the production of offspring in several domestic animal species, but as yet, it has not been successfully applied in human reproductive medicine. This study examined the effect of alginic acid microencapsulation on human sperm membrane integrity (viability) and sperm DNA fragmentation (SDF) following storage for 24 hr at 37°C. The cumulative sperm viability (Log-rank, Mantel–Cox; Chi-square = 114.95, p = .000) and cumulative sperm DNA fragmentation (Log-rank, Mantel–Cox; Chi-square = 187.86, p = .000) of encapsulated spermatozoa were substantially improved when compared to control spermatozoa. Significant differences in the dynamic behaviour of different individuals were only apparent for sperm viability in microencapsulated samples (p = .021) while no significant differences were observed in control spermatozoa (p = .245); the equivalent comparison for SDF showed no differences (control p = .320; microencapsulated p = .432). We present potential scenarios for the use of microencapsulated human spermatozoa in reproductive medicine.     

Resumen ejecutivo del Documento de Consenso de la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC) y de la Asociación Española de Cirujanos (AEC) en profilaxis antibiótica en cirugía

Antibiotic prophylaxis in surgery is one of the most effective measures for preventing surgical site infection, although its use is frequently inadequate and may even increase the risk of infection, toxicities and antimicrobial resistance. As a result of advances in surgical techniques and the emergence of multidrug-resistant organisms, the current guidelines for prophylaxis need to be revised.The Sociedad Española de Enfermedades Infecciosas (Spanish Society of Infectious Diseases and Clinical Microbiology) (SEIMC) together with the Asociación Española de Cirujanos (Spanish Association of Surgeons) (AEC) have revised and updated the recommendations for antibiotic prophylaxis in surgery to adapt them to any type of surgical intervention and to current epidemiology. This document gathers together the recommendations on antimicrobial prophylaxis in the various procedures, with doses, duration, prophylaxis in special patient groups, and in epidemiological settings of multidrug resistance to facilitate standardized management and the safe, effective and rational use of antibiotics in elective surgery.     

Complicaciones durante la intubación traqueal repetida en la unidad de cuidados intensivos. Estudio prospectivo,observacional comparando primera intubación y reintubación

Background of the studyThe goal of the study was to compare the incidence of complications, technical difficulty of intubation and physiologic pre-intubation status between the first intubation and reintubation performed on the same patient in an ICU.Materials and methodsThe study was approved by the ethics committee of Galicia (Santiago-Lugo, code No. 2015-012). Due to the observational, noninterventional, and noninvasive design of this study, the need for written consent was waived by the ethics committee of Galicia. Patients requiring tracheal intubation and reintubation in the ICU were included in this prospective observational study. Main endpoint was to compare the incidence of complications, physiologic pre-intubation status, and the rate of technical difficulty of intubation between the first intubation and reintubation performed on the same patient in an ICU.Results and discussion504 patients were intubated in our ICU during the study period, and 82 (16%) required reintubation. There was no difference between the first intubation and reintubation regarding number of total complication (35% vs 33%; P = .86), hypotension (24% vs 24%; P = 1), hypoxia (26% vs 26%; P = 1), esophageal intubation (1% vs 1%; P = 1), and bronchoaspiration (2% vs 1%; P = .86). Physiologic pre-intubation status and technical difficulty of intubation did not differ between the first intubation and reintubation.ConclusionsIn our ICU patients requiring tracheal reintubation, incidence of complications, physiologic pre-intubation status, and technical difficulty of intubation did not differ between the first intubation and reintubation.

Safety and effectiveness of REALIZE adjustable gastric band: 5-year prospective study

BackgroundThe long-term safety results of the REALIZE (Ethicon Endo-Surgery, Inc., Cincinnati, OH) adjustable gastric band collected in this prospective, multicenter study in patients with morbid obesity are presented.ObjectivesTo determine the reoperation rate, including band revisions, replacements, and explants, resulting from a serious adverse device-related event through years 4 and 5. Various efficacy measures were also assessed as secondary objectives.SettingNine academic and/or private institutions.MethodsThe participating institutions enrolled 303 patients, who were then assessed on an annual basis, with 231 patients completing 5 years of follow-up. The study parameters included reoperation rates, changes in percentage of excess weight loss (%EWL), and changes in body mass index (BMI), as well as parameters of diabetes and dyslipidemia. Quality of life was assessed using the Short Form (SF)-36 and the Impact of Weight on Quality of Life-Lite questionnaires.ResultsThe reoperation rate due to a serious adverse event in this population at 5 years after implantation with the REALIZE gastric band was 8.9%. The most common serious adverse event was band slippage, which affected 6.9% of the study population. The mean %EWL was 35.6% ± 26.84%, and the decrease in mean BMI was ?7.01 ± 5.45 kg/m² at 5 years. Patients experienced improvements in mean glycated hemoglobin and serum lipid levels, in addition to improvements in the quality of life measures.ConclusionNo new safety concerns were identified during the 5 years of follow-up. Although the results of this study did not meet the predefined safety criteria of 8% or less, the safety profile and long-term effectiveness observed in this study are consistent with those in the current literature.     

Cross neutralization of SARS-CoV-2 omicron subvariants after repeated doses of COVID-19 mRNA vaccines

We have measured the humoral response to messenger RNA (mRNA) vaccines in COVID-19 naïve and convalescent individuals. Third doses of mRNA COVID-19 vaccines induced a significant increase in potency and breadth of neutralization against SARS-CoV-2 variants of concern (VoC) including Omicron subvariants BA.1, BA.2, and BA.2.12.1, that were cross-neutralized at comparable levels and less for BA.4/5. This booster effect was especially important in naïve individuals that only after the third dose achieved a level that was comparable with that of vaccinated COVID-19 convalescents except for BA.4/5. Avidity of RBD-binding antibodies was also significantly increased in naïve individuals after the third dose, indicating an association between affinity maturation and cross neutralization of VoC. These results suggest that at least three antigenic stimuli by infection or vaccination with ancestral SARS-CoV-2 sequences are required to induce high avidity cross-neutralizing antibodies. Nevertheless, the circulation of new subvariants such as BA.4/5 with partial resistance to neutralization will have to be closely monitored and eventually consider for future vaccine developments.     

Androgenic Activity of Antiandrogens Predicted by Fit into DNA

Computer modeling including graphics and energy calculations were employed for the first time to examine the stereochemical fit of antiandrogens into double-stranded DNA. In this study, we assessed the relative fit of antiandrogens in the cavity between base pairs known to accommodate androgens. When compared to testosterone which was given a normalized value of 100%, the antiandrogens manifested the following order of fit: RU23908 (88%) > hydroxyflutamide (71%) > cyproterone acetate (41%). A correlation was observed between the relative fit of the antiandrogens and reported agonistic properties as assessed by the ability to increase nuclear androgen receptor levels in the rat ventral prostate. These findings may be useful in the design and development of androgen antagonists without agonistic activity.
