Beyond the spine-specific pathology, patient factors such as associated medical and psychosocial conditions, understanding of the treatment process, and the degree of patient activation-defined as the ability of the individual to utilize the available information and actively engage in making their healthcare decisions-can influence outcomes after posterolateral lumbar fusion (PLF) surgery. A retrospective observational cohort study of 177 patients undergoing PLF at a single institution was conducted. Patient demographics, medical and psychosocial risk factors, and outcomes were compared between patients who attended a nurse navigator-led group preoperative education course and those who did not. Patients attending the course were younger, more likely to undergo one-level fusion, less likely to undergo 5- or more-level fusion, and had less comorbidity burden as measured by the hierarchical condition categories score. No differences in psychosocial risk factors were observed between groups. Course attendees had a significantly shorter length of stay (2.12 vs. 2.60 days, p = .042) and decreased average hospital cost (U.S. $10,149 vs. U.S. $14,792, p less then .001) than those who did not attend; no differences in other outcomes were observed. After controlling for differences in risk factors, patients enrolled in a preoperative education course demonstrated a statistically significant reduction in hospital cost (β=-4,143, p less then .001). Preoperative education prior to PLF surgery may reduce hospital cost, possibly through increased patient activation. Given the relatively high prevalence of psychosocial risk factors in this and similar patient populations, optimizing patient activation and engagement is important to achieve high value care. Based on our findings, nurse navigator-led preoperative education appears to be valuable in this patient population and should be included in enhanced recovery protocols.Surgical-site infections (SSI) contribute to increased hospital length of stay, readmission rates, cost, and morbidity and mortality rates. The spine service line at a suburban Level II trauma center encountered 2 SSIs among the spine fusion population within a 6-month period. This did not meet the organization's internal benchmark of zero. A pilot quasi-experimental design was used to determine whether preoperative cleansing with 2% chlorhexidine gluconate (CHG)-impregnated cloths versus current practice of bathing with 4% CHG solution would reduce SSIs. Infection rates were measured using simple percentages. Level of significance was p less then .05. Outcome data showed a reduction in SSIs from 3.9% to 1.9% with use of 2% CHG-impregnated cloths. There was no significant difference found between the use of 2% CHG-impregnated cloths and 4% CHG solution (p = .524). This quality improvement change, combined with a strengthened preoperative bundle approach, has permanently been adopted within the spine service line. From October 2017 to March 2021, the spine service line has had zero SSIs within the spine fusion population.For decades, the sufficient cause model and the counterfactual model have shaped our understanding of causation in biomedical science, and the link between these two models has enabled us to obtain a deeper understanding of causality. Recently, a new causal model-the marginal sufficient component cause model-was proposed and applied in the context of interaction or mediation. The proponents of this model have emphasized its utility in visualizing the presence of "agonism" (a subtype of mechanistic interaction) in the counterfactual framework, claiming that the concept of agonism has not been clearly defined in causal inference and that agonistic interaction cannot be visualized by the conventional sufficient cause model. In this article, we illustrate that careful scrutiny based on the conventional sufficient cause model yields further insights into the concept of agonism in a more biologic sense. We primarily focus on the following three points (1) "agonism" defined in the counterfactual model can be visualized as sets of sufficient causes in the conventional sufficient cause model; (2) although the so-called independent competing assumption or no redundancy assumption may seem irrelevant in the marginal sufficient component cause model, researchers do need to assume that potential completion times of relevant marginal sufficient causes differ; and (3) possibly differing potential completion times of marginal sufficient causes cannot be discerned until their hidden mechanistic paths are considered in the conventional sufficient cause model. In this rapidly progressing field of research, decades after its introduction, the sufficient cause model retains its worth.
The pathophysiological mechanisms of acute schizophrenia are largely unknown, but it is widely accepted that dopamine D2 receptors (DRD2s) are involved in psychosis treatments for schizophrenic patients. We suggest that genetic variation in these receptors may play a role in patients' responses to commonly used antipsychotics, particularly D2-blockers.

This study included adult patients with ICD-10 diagnoses of schizophrenia and current acute psychosis who were treated with antipsychotics. All patients underwent genotyping for DRD2 rs2514218 polymorphism. The definition of overall treatment response was based on changes in treatment scheme no changes indicated a good response, and changes indicated a limited response.

There were 275 inpatients (38.1% of whom were female; mean age = 32.7 years, SD = 11.1 years) who met the inclusion criteria. Of the participants, 99 were good responders (34% of whom were female), and 176 were limited responders (40% of whom were female). No differences in demographic, premorbid, or disease characteristics were found. The number of patients that were homozygous for the risk allele was significantly greater in the limited response group than in the good response group.

Our findings suggest that the risk variant at the DRD2 locus can be used as an indicator for patients' responses to antipsychotics without direct DRD2-blocking, thereby shortening the time needed for drug selection.

Both the composition of sex chromosomes and the environment determine sex in vertebrates. It is assumed that transcription level regulation drives this cascade of mechanisms; however, transcription factors can alter gene expression beyond transcription initiation by controlling pre-mRNA splicing and thereby mRNA isoform production. Using the key time window in sex determination and gonad development in mice, it has been reported that new non-transcriptional events, such as alternative splicing, could play a key role in sex determination in mammals. We know the role of key regulatory factors, like WT1(+/-KTS) or FGFR2(b/c) in pre-mRNA splicing and sex determination, indicating that important steps in the vertebrate sex determination process probably operate at a post-transcriptional level. Here, we discuss the role of pre-mRNA splicing regulators in sex determination in vertebrates, focusing on the new RNA-seq data reported from mice fetal gonadal transcriptome.
The coronavirus 2019 pandemic has altered how modern healthcare is delivered to patients. Concerns have been raised that masks may hinder effective communication, particularly in patients with hearing loss. The purpose of this study is to determine the effect of masks on speech recognition in adult patients with and without self-reported hearing loss in a clinical setting.

Adult patients presenting to an otolaryngology clinic were recruited. A digital recording of 36 spondaic words was presented to each participant in a standard clinical exam room. Each word was recorded in 1 of 3 conditions no mask, surgical mask, or N95 mask. Participants were instructed to repeat back the word. The word recognition score was determined by the percent correctly repeated.

A total of 45 participants were included in this study. Overall, the mean word recognition score was 87% without a mask, 78% with a surgical mask, and 61% with an N95 mask. Among the 23 subjects (51.1%) with self-reported hearing loss, the average word recognition score was 46% with an N95 mask compared to 79% in patients who reported normal hearing (p < 0.001).

Our results suggest that masks significantly decrease word recognition, and this effect is exacerbated with N95 masks, particularly in patients with hearing loss. As masks are essential to allow for safe patient-physician interactions, it is imperative that clinicians are aware they may create a barrier to effective communication.

Chronic hyponatremia has been reported to be associated with low solute intake and low creatinine excretion (reflecting likely sarcopenia). We wanted to study the effect, on the long term, of correction of hyponatremia on solute and creatinine excretion in chronic SIADH.

We made a retrospective review of clinical and biochemical data of patients with euvolemic hyponatremia. We analyzed 24-h urine solute and creatinine excretion in volunteers with hyponatremia induced by dDAVP over 4 days, in 12 patients with chronic SIADH (>1 month) before and after a few days of SNa correction and in 12 patients (6 women and 6 men) before and after 3 months of SNa correction by a vaptan or urea.

We confirm a low urine creatinine and solute excretion only in patients with chronic hyponatremia (>1 month). Correction of SNa (from 127 ± 2.3 mEq/L to 139 ± 2.8 mEq/L) for >3 months, in the 12 patients (mean age 58 ± 18), was associated with an increase in 24-h creatinine excretion (from 986 ± 239 to 1,238 ± 220 mg; p < 0.02) and in patients treated with a vaptan (n = 5) solute excretion increased from 656 ± 207 mmol/24 h to 960 ± 193 mmol/24 h (p < 0.02). Sodium excretion increased also in the 12 patients (from 100 ± 53 mEq/24 h to 169 ± 38 mEq/24 h; p < 0.01).

Chronic hyponatremia (>1 month) is associated with a decrease in solute output (or intake) and in creatinine excretion. In many patients, these abnormalities are reversible in the long term.

It is plausible that gene polymorphisms in tumor necrosis factor-α (TNF-α), interleukin (IL)-1, IL-6, IL-8, and IL-18 may affect predisposition to microvascular complications of diabetes mellitus (DM), but the results of the so far published studies remain controversial.

We conducted this meta-analysis to clarify relationships between TNF-α/IL-1/IL-4/IL-8/IL-18 polymorphisms and predisposition to microvascular complications of DM by pooling the findings of eligible studies.

A comprehensive search of PubMed, Embase, Web of Science, and CNKI was endorsed by us to identify already published studies. Forty-nine studies were found to be eligible for the meta-analyses.

The pooled meta-analyses results showed that genotypic frequencies of TNF-α -238 G/A, TNF-α -308 G/A, TNF-α -1,031 T/C, IL-1A -889 C/T, IL-1B -511 C/T, IL-6 -572 G/C, and IL-18 -137 G/C polymorphisms among patients with diabetic nephropathy (DN) and controls differed significantly.
