Intraocular transmission of exogenous pathogens in cataract surgery can lead to endophthalmitis. This review evaluates the features of endophthalmitis clusters secondary to pathogen transmission in cataract surgery. Articles reporting on pathogen transmission in cataract surgery were identified via searches of Ovid MEDLINE, EMBASE, and Cochrane CENTRAL, and a total of 268 eyes from 24 studies were included. The most common source of infectious transmission was attributed to a contaminated intraocular solution (ie, irrigation solution, viscoelastic, or diluted antibiotic; n = 10). Visual acuity at presentation with infectious features was 1.89 logMAR (range: 1.35 to 2.58; ∼counting fingers) and 1.33 logMAR (range: 0.04 to 3.00; Snellen: ∼20/430) at last follow-up. Patients with diabetes had worse outcomes compared with patients without diabetes. The most frequently isolated pathogen from the infectious sources was Pseudomonas sp. (50.0%). This review highlights the various routes of pathogen transmission during cataract surgery and summarizes recommendations for the detection, prevention, and management of endophthalmitis clusters.

Disclosing idiosyncratic preferences can help to broker new social interactions. For instance, strangers exchange music preferences to signal their identities, values, and preferences. Recognizing that people’s physical appearances guide their decisions about social engagement, we examined whether cues to people’s music preferences in their physical appearance and expressive poses help to guide social interaction. We found that perceivers could detect targets’ music preferences from photos of their bodies, heads, faces, eyes, and mouths (but not hair) and that the targets’ apparent traits (e.g., submissiveness, neatness) undergirded these judgments. Perceivers also desired to meet individuals who appeared to match their music preferences versus those who did not. Music preferences therefore seem to manifest in appearance, regulating interest in others and suggesting that one’s identity redundantly emerges across different types of cues. People may thus infer others’ music preferences to identify candidates for social bonding.

OBJECTIVE People gather important social information from subtle nonverbal cues. Given that one's attachment style can meaningfully affect the quality of one's relationships, we investigated whether people could perceive men's and women's attachment styles from photos of their neutral faces. METHOD In two studies, we measured targets' attachment styles then asked participants (total N = 893) to judge the male and female targets' attachment anxiety and avoidance from photos of their neutral faces (total N = 331) and to report their own attachment anxiety and avoidance. RESULTS Participants detected men's attachment style from face photos significantly better than chance in an initial exploratory study and in a preregistered replication but did not consistently detect women's attachment style from their face photos. Moreover, participants' own attachment style biased these first impressions: Individuals with greater attachment anxiety viewed others as more anxiously attached. CONCLUSIONS People can detect some hints of unacquainted others' attachment styles from their faces but their own anxious attachment can bias these judgments.

Ophthalmology - Abstract
Eliminating low-yield testing can reduce the burden on modern healthcare systems. Our purpose is to determine whether routine preoperative assessment impacts the incidence of perioperative complications in ophthalmic surgery. We conducted a comprehensive search of Ovid MEDLINE, EMBASE, and Cochrane Library databases to identify studies investigating the incidence of perioperative complications following any preoperative assessment (Registration#164008). Four randomized controlled trials (RCTs) and 5 observational studies were selected for inclusion. Risk of bias assessment revealed a lack of masking and insufficient statistical power in RCTs, and confounding in observational studies. Routine preoperative testing, including laboratory tests, electrocardiogram, and imaging studies, did not decrease the incidence of adverse events or risk of perioperative ocular and systemic complications in most studies. Two cohort studies (one retrospective, one prospective) suggested that patients with certain preexisting health conditions were at increased risk for adverse events perioperatively. Another retrospective study found a lower risk of complications in high-risk patients who underwent evaluation. While patients with comorbidities may be at increased risk of adverse events, the role of preoperative assessment is not well delineated in this population. Further study is required to determine the comparative safety, effectiveness, and implementation of alternative assessment tools.

Recognizing others' humanity is fundamental to how people think about and treat each other. People often ascribe greater humanness to groups that they socially value, but do they also systematically ascribe social value to different individuals? Here, we tested whether people (de)humanize individuals based on social traits inferred from their facial appearance, focusing on attractiveness and intelligence. Across five studies, less attractive and less intelligent-looking individuals seemed less human, but this varied by target gender: Attractiveness better predicted humanness attributions to women whereas perceived intelligence better predicted humanness attributions to men (Study 1). This difference seems to stem from gender stereotypes (preregistered Studies 2 and 3) and even extends to attributions of children's humanness (preregistered Study 4). Moreover, this gender difference leads to biases in moral treatment that confer more value to the lives of attractive women and intelligent-looking men (preregistered Study 5). These data help to explain how interpersonal judgments of individuals interact with intergroup biases to promote gender-based discrimination, providing greater nuance to the mechanisms and outcomes of dehumanization.

The ecological theory of social perception suggests that people’s first impressions should be especially accurate for judgments relevant to their goals. Here, we tested whether people could accurately judge others’ levels of antigay prejudice and whether gay men’s accuracy would exceed straight men’s accuracy in making these judgments. We found that people judged men’s (but not women’s) levels of antigay prejudice accurately from photos of their faces and that impressions of facial power supported their judgments. Gay men and straight men did not significantly differ in their sensitivity to antigay prejudice, however. People may therefore judge others’ levels of prejudice accurately regardless of their personal stake in its consequences.

Purpose: To report a case of Purtscher-like retinopathy secondary to acute pancreatitis caused by medication-induced calcium-alkali syndrome in a pregnant woman.Methods: Case reportResults: A 39-year-old 23-week pregnant patient complained of visual disturbances during admission for acute pancreatitis precipitated by calcium-alkali syndrome. History revealed the acute ingestion of over 2,400 mg of elemental calcium from over the counter medication in the background of longstanding use. Visual acuity was counting fingers at 1 foot bilaterally. Posterior segment exam revealed Purtscher-flecken in the posterior pole with scattered dot hemorrhages. Optical coherence tomography (OCT) revealed inner retinal thickening and increased hyper-reflectivity. OCT angiography demonstrated loss of flow primarily in the superficial capillary plexuses. The patient was diagnosed with Purtscher-like retinopathy and observed. Two months follow up revealed resolution of the funduscopic findings and visual acuity improved minimally to 20/200 in the right eye and counting fingers in the left eye.Conclusion: Common over the counter medication can potentiate a calcium-alkali syndrome capable of causing a Purtscher-like retinopathy.

Please do not copy or cite without author's permission. The final article is available, upon publication, at: https://doi.apa.org/doi/10.1037/bul0000220 To what extent are research results influenced by subjective decisions that scientists make as they design studies? Fifteen research teams independently designed studies to answer five original research questions related to moral judgments, negotiations, and implicit cognition. Participants from 2 separate large samples (total N 15,000) were then randomly assigned to complete 1 version of each study. Effect sizes varied dramatically across different sets of materials designed to test the same hypothesis: Materials from different teams rendered statistically significant effects in opposite directions for 4 of 5 hypotheses, with the narrowest range in estimates being d = 0.37 to 0.26. Meta-analysis and a Bayesian perspective on the results revealed overall support for 2 hypotheses and a lack of support for 3 hypotheses. Overall, practically none of the variability in effect sizes was attributable to the skill of the research team in designing materials, whereas considerable variability was attributable to the hypothesis being tested. In a forecasting survey, predictions of other scientists were significantly correlated with study results, both across and within hypotheses. Crowdsourced testing of research hypotheses helps reveal the true consistency of empirical support for a scientific claim.

Interpersonal accuracy correlates modestly across different domains. Although some research has explored factors that predict accuracy within specific domains of interpersonal judgment (e.g., social attributes), whether any variables might predict interpersonal accuracy generally across different domains remains in question. Subjective socioeconomic status (SES) has recently emerged as an important moderator of various social cognitions, such as contextual focus and empathic accuracy. Moreover, people lower in SES tend to show greater interpersonal engagement and attention; thus, we wondered whether individuals with lower subjective SES might exhibit superior interpersonal accuracy in multiple domains. Indeed, across four studies, we found that subjective SES inversely correlated with accuracy in three different domains of interpersonal accuracy: social attributes, situational affect, and emotion. These findings therefore demonstrate that subjective SES may predict broad interpersonal accuracy abilities and suggest that, despite modest relationships between different types of first impression accuracy, the correlates of such accuracy can still operate across domains.

Though many of people’s impressions about each other stem from qualities that are obvious or apparent, social perceptions also rely on a variety of subtle cues that guide judgment and behavior. For example, emerging work has increasingly elucidated the conditions and means by which individuals’ accuracy in judging others’ sexual orientation is better than chance. We discuss these here, focusing on four domains from which people draw cues to accurately perceive sexual orientation: how people adorn themselves (adornment), how they move (actions), how they sound (acoustics), and how they look (appearance). Moreover, we describe how certain factors, such as one’s own sexual orientation, can constrain or facilitate this accuracy and describe the various negative social and occupational consequences that may result from cues that someone is gay or straight.

Over the last ten years, Oosterhof and Todorov’s valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgments of faces. To which world regions this model applies is a critical, yet unanswered, question. We will address this question by replicating Oosterhof and Todorov’s methodology across multiple world regions.

Deciphering the genetic and developmental causes of the disproportionate rarity, inviability, and sterility of hybrid males, Haldane's rule, is important for understanding the evolution of reproductive isolation between species. Moreover, extrinsic and prezygotic factors can contribute to the magnitude of intrinsic isolation experienced between species with partial reproductive compatibility. Here, we use the nematodes Caenorhabditis briggsae and C. nigoni to quantify the sensitivity of hybrid male viability to extrinsic temperature and developmental timing, and test for a role of mito-nuclear incompatibility as a genetic cause. We demonstrate that hybrid male inviability manifests almost entirely as embryonic, not larval, arrest and is maximal at the lowest rearing temperatures, indicating an intrinsic-by-extrinsic interaction to hybrid inviability. Crosses using mitochondrial substitution strains that have reciprocally introgressed mitochondrial and nuclear genomes show that mito-nuclear incompatibility is not a dominant contributor to postzygotic isolation and does not drive Haldane's rule in this system. Crosses also reveal that competitive superiority of X-bearing sperm provides a novel means by which postmating prezygotic factors exacerbate the rarity of hybrid males. These findings highlight the important roles of gametic, developmental, and extrinsic factors in modulating the manifestation of Haldane's rule.

Many Labs 3 (Ebersole et al., 2016) failed to replicate a classic finding from the Elaboration Likelihood Model of persuasion (Cacioppo, Petty, & Morris, 1983; Study 1). Petty and Cacioppo (2016) noted possible limitations of the Many Labs 3 replication (Ebersole et al., 2016) based on the cumulative literature. Luttrell, Petty, and Xu (2017) subjected some of those possible limitations to empirical test. They observed that a revised protocol obtained evidence consistent with the original finding that the Many Labs 3 protocol did not. This observe-hypothesize-test sequence is a model for scientific inquiry and critique. To test whether these results advance replicability and knowledge transfer, we conducted direct replications of Luttrell et al. in nine locations (Total N = 1219). We successfully replicated the interaction of need for cognition and argument quality on persuasion using Luttrell et al.'s optimal design (albeit with a much smaller effect size; p f 2 = 0.025, 95%CI [0.006, 0.056]) but failed to replicate the interaction that indicated that Luttrell et al.’s optimal protocol performed better than the Many Labs 3 protocol ( p = 0.135, pseudo R 2 = 0.002). Neither Luttrell et al.'s effect size estimate for the need for cognition by argument quality interaction nor their estimate for the interaction with replication protocol fell within our corresponding 95% confidence intervals. Nevertheless, pragmatically, we favor the Luttrell et al. protocol with large samples for future research using this paradigm.
