3 protein expression before and after neoadjuvant intensive hormone therapy, the authors determined that hormone therapy is associated with a decrease in B7-H3 protein levels, suggesting that androgen signaling may positively regulate B7-H3 expression. These results may help to guide the design of future clinical trials and to develop biomarkers of response in such trials.
Solid organ transplant recipients (SOTR) are at high risk of keratinocyte carcinoma (KC). Long-term evidence for acitretin as chemoprophylaxis in this population is lacking.
To determine the benefit of long-term acitretin for KC chemoprevention in SOTR.
A retrospective cohort study of SOTR treated with acitretin at an Australian transplant dermatology clinic was performed. General estimating equations were used to evaluate change in rates of histologically confirmed KC in the 6-12 months prior to acitretin and following a minimum 6 months of treatment. A control group of patients within the same service was included, comprising SOTR who were not treated with acitretin.
Twenty-two patients received acitretin treatment for at least 6 months, eighteen for at least 5 years and four for at least 9 years. The median KC rate pretreatment was 3.31 per year (IQR 1.93, 5.40). There was a significant reduction in the rate of KC in the first year of acitretin treatment (IRR 0.41, 95% CI 0.22, 0.76, P = 0.005), and this effect was observed for 5 years (IRR at 5 years 0.34, 95% CI 0.17, 0.67, P = 0.002). The control group had no statistically significant change in KC rate over time in the study.
Acitretin appears to be well-tolerated and effective in reducing KC in SOTR for at least 5 years. Study limitations include its retrospective nature, small sample size and lack of blinding.

Secondary outcomes during the three-month project included decreasing the patient's length of stay and inpatient care costs. We used the Lean Six Sigma methodology and measured aggregated patient outcomes of opioid use, length of hospital stay, and total cost. In addition, we incorporated the ERAS protocol into the electronic health record. Results showed a reduction use of morphine milligram equivalents of opioids, a slight decrease in length of hospital stay, and no change in the inpatient costs. The team recognized that implementation of an ERAS protocol is a best practice to reduce opioid use in patients undergoing a cesarean birth and decided to permanently include it in patient care processes.Perioperative communication can be ineffective and result in delays or adverse events. Coronavirus disease 2019 (COVID-19) has placed demands on health care leaders and personnel to integrate information quickly and accurately. When caring for patients diagnosed with COVID-19 or whose infection status was unknown, perioperative personnel at one facility discovered communication gaps associated with the environmental cleaning process and hand-over reports. A project team comprising perioperative nurses created five tools to provide critical information to help diverse team members share the same mental model. The project team created one tool in English and Spanish to meet the needs of environmental services personnel whose primary language was Spanish. The team created another tool to support communication with central processing department personnel and facilitate prioritization of case cart cleaning when needed. The development and implementation of the communication tools helped to provide a safe working environment during the COVID-19 pandemic.Perioperative care of the patient with alpha-gal syndrome Key words alpha-gal syndrome (AGS), red meat allergy, allergic reaction, mammalian-derived ingredients, gelatin. Overnight storage of sterile supplies Key words sterile supplies, event-related sterility, terminal cleaning, damp dusting, instrument table. Unsterile medication cartridges Key words dental cartridge, local anesthesia, lidocaine, alcohol, sterile field. Personnel traffic into the OR Key words OR traffic, door openings, airflow, environmental contamination, automatic doors.Personnel follow hospital policies and regulatory guidelines to prevent surgical site infections. However, a potentially contaminated item may be overlooked-the linen. When perioperative team members transport patients to the OR, the linen on the beds and transport carts can contain a variety of microorganisms. Textile surfaces can serve as reservoirs for microorganisms that can be transferred to health care providers, patients, and the environment. These pathogens may then infect patients, particularly those who are immunocompromised or have direct portals of entry (eg, catheters, incision sites). This article provides an overview of how microorganisms that cause health care-associated infections can survive and thrive on hospital linen and related equipment; discusses the linen laundering, transport, and storage processes and best practices; and discusses antimicrobial interventions-including a silver-ion laundering additive that was added as an infection prevention measure to the laundry production cycle at a medical center's contracted laundry facility.Development of nondestructive techniques for estimating egg parameters requires a comprehensive approach based on mathematical theory. Basic properties used to solve theoretical and applied problems in this respect are volume (V) and surface area (S). There are respective formulae for calculating V and S of spherical, ellipsoidal, and ovoid eggs in classical egg geometry; however, the mathematical description and calculation of these parameters for pyriform eggs have remained elusive. In the present study, we derived the appropriate formulae and established that this would be not only applicable and valid for the category of pyriform eggs, but also universal and explicit for all other naturally occurring avian egg shapes. Thus, we have demonstrated "mathematical progression" of this natural object, considering the egg as a sequence of geometric figures that transform from one to another in the following sequence of shapes sphere → ellipsoid → ovoid (whose profile corresponds to Hügelschäffer's model) → pyriform ovoid.Chronic heart failure (CHF) is a common clinical heart disease. In recent years, traditional Chinese medicines have shown good outcomes in CHF treatment. We aimed to explore the therapeutic effect of Shen Qi Li Xin formula (SQLXF) in CHF. CHF rats were treated with SQLXF at the doses of 8.48, 16.96, and 33.92 g/kg/d once a day for 4 weeks by intragastric administration. The hemodynamic and cardiac function parameters of the rats were monitored by conduction echocardiography. In our results, SQLXF treatment at the doses of 16.96 and 33.92 g/kg/d significantly improved the haemodynamics and cardiac function of CHF rats by enhancing the levels of LVSP, +dp/dtmax, -dp/dtmax, LVEF and LVFS and reducing the levels of LVEDP, LVEDD and LVESD. SQLXF treatment at 16.96 and 33.92 g/kg/d also attenuated the damage of myocardial tissues in CHF rats. In addition, compared with normal rats, the number of pericytes was reduced in myocardial tissues of CHF rats. SQLXF treatment at the doses of 16.96 and 33.92 g/kg/d obviously increased the number of pericytes and proliferation of endothelial cells and promoted angiogenesis in myocardial tissues of CHF rats. In vitro, SQLXF impaired low-oxygen-induced inhibition of cell viability and promotion of apoptosis in primary pericytes. Importantly, SQLXF enhanced the adhesion ability of pericytes to endothelial cells. In conclusion, SQLXF improved myocardial injury in CHF rats by enhancing the interaction between pericytes and endothelial cells, suggesting that SQLXF may be a potential drug for CHF treatment.
Few studies have reported the cost and cost-effectiveness of workplace interventions to reduce sedentary time. The purpose of this study was to complete an economic evaluation of a multilevel intervention to reduce sitting time and increase light-intensity physical activity (LPA) among employees.
We conducted a retrospective within-trial cost and cost-effectiveness analysis (CEA) to compare a 12-month multilevel intervention with (STAND+) and without (MOVE+) a sit-stand workstation, across 24 worksites (N=630 employee participants) enrolled in a cluster randomized clinical trial. We estimated the intervention costs using activity-based costing strategy. The intervention costs were further expressed as per person and per worksite. CEA was conducted using an incremental cost-effectiveness ratio (ICER) metric, expressed as costs for additional unit of sitting time (minute/day), LPA (minutes/day), cardiometabolic risk score, and quality-adjusted life years (QALY) increased/decreased at 12 months. We assessed ed to reduce workplace sitting time. Future research into work productivity outcomes in terms of cost-benefits for employers is warranted.
Youth at clinical high-risk (CHR) for psychosis present with neuropsychological impairments relative to healthy controls (HC), but whether these impairments are distinguishable from those seen among putatively lower risk peers with other psychopathology remains unknown. We hypothesized that any excess impairment among CHR cohorts beyond that seen in other clinical groups is minimal and accounted for by the proportion who transition to psychosis (CHR-T).
We performed a systematic review and meta-analysis of studies comparing cognitive performance among CHR youth to clinical comparators (CC) who either sought mental health services but did not meet CHR criteria or presented with verified nonpsychotic psychopathology.
Twenty-one studies were included representing nearly 4000 participants. Individuals at CHR showed substantial cognitive impairments relative to HC (eg, global cognition g = -0.48 [-0.60, -0.34]), but minimal impairments relative to CC (eg, global cognition g = -0.13 [-0.20, -0.06]). Any excess impairment among CHR was almost entirely attributable to CHR-T; impairment among youth at CHR without transition (CHR-NT) was typically indistinguishable from CC (eg, global cognition, CHR-T g = -0.42 [-0.64, -0.19], CHR-NT g = -0.09 [-0.18, 0.00]; processing speed, CHR-T g = -0.59 [-0.82, -0.37], CHR-NT g = -0.12 [-0.25, 0.07]; working memory, CHR-T g = -0.42 [-0.62, -0.22], CHR-NT g = -0.03 [-0.14, 0.08]).
Neurocognitive impairment in CHR cohorts should be interpreted cautiously when psychosis or even CHR status is the specific clinical syndrome of interest as these impairments most likely represent a transdiagnostic vs psychosis-specific vulnerability.
