Early-life infection dynamics and genomic diversity of adenoviruses in a wild primate (Theropithecus gelada) Open
In humans, adenoviruses (AdVs) are frequently associated with respiratory illnesses, posing risks to children with developing immune systems and immunocompromised individuals. Outbreaks and epidemics are generally centred in close-contact …

For <span>CPR</span> or Not‐For‐<span>CPR</span>? Demographic Factors Predict Resuscitation Order Documentation and <span>CPR</span> Status in General Surgery Patients Open
Background To improve healthcare equity, this study aimed to determine which demographic factors are associated with resuscitation order documentation and not‐for‐cardiopulmonary resuscitation (CPR) status in general surgery patients. Meth…

Postoperative inflammatory responses and association with in‐hospital mortality after general surgery Open
Background The relationship between postoperative in‐hospital mortality and inflammatory markers has not been well described. This study aimed to characterize the association between specific clinical markers of inflammation and in‐hospita…
Female reproductive ageing persists despite high infanticide risk in chacma baboons and geladas Open
Across mammals, fertility and offspring survival are often lowest at the beginning and end of females’ reproductive careers. However, extrinsic drivers of reproductive success—including infanticide by males—could stochastically obscure the…
Male Infanticide in the Northern Purple‐Faced Langur (<i>Semnopithecus vetulus</i> Philbricki) in the Kaludiyapukuna Forest Reserve, Sri Lanka Open
Infanticide, the killing of conspecific infants, has been observed in many species, including rodents, carnivores, and notably, primates. Although several adaptive and non‐adaptive hypotheses have been proposed to explain this phenomenon, …
Host–gut microbiota interactions during pregnancy Open
Mammalian pregnancy is characterized by a well-known suite of physiological changes that support fetal growth and development, thereby positively affecting both maternal and offspring fitness. However, mothers also experience trade-offs be…
Timing of conceptions in Phayre's leaf monkeys: Energy and phytochemical intake Open
Objectives Raising offspring imposes energetic costs, especially for female mammals. Consequently, seasons favoring high energy intake and sustained positive energy balance often result in a conception peak. Factors that may weaken this co…
Aggression rates increase around seasonally exploited resources in a primarily grass-eating primate Open
Female social relationships are often shaped by the distribution of dietary resources. Socioecological models predict that females should form strict linear dominance hierarchies when resources are clumped and exhibit more egalitarian soci…

Sociocultural and Demographic Factors Predict Readmissions for General Surgery Patients Open
Introduction Readmission is a poor outcome for both patients and healthcare systems. The association of certain sociocultural and demographic characteristics with likelihood of readmission is uncertain in general surgical patients. Method …
The geographic diversity of authorship in leading general surgery journals; A study of 24,332 authors Open
Authorship in leading general surgery journals is predominantly from wealthy, Western countries. Authorship is associated with affiliation with a high HDI country, with few authors from medium or low HDI countries. There is a lack of repre…
Bushfire alters the gut microbiome in endangered Kangaroo Island echidnas (<i>Tachyglossus aculeatus multiaculeatus</i>) Open
Kangaroo Island experienced extensive bushfires in December 2019 and January 2020, affecting almost half of the island. This impacted several threatened species including the Kangaroo Island echidnas ( Tachyglossus aculeatus multiaculeatus…
Best practices for genotype imputation from low‐coverage sequencing data in natural populations Open
Monitoring genetic diversity in wild populations is a central goal of ecological and evolutionary genetics and is critical for conservation biology. However, genetic studies of nonmodel organisms generally lack access to species‐specific g…
Vascularization underlies differences in sexually selected skin coloration in a wild primate Open
Male reproductive competition can select for condition‐dependent, conspicuous traits that signal some aspect of fighting ability and facilitate assessment of potential rivals. However, the underlying mechanisms that link the signal to a ma…
Opportunities for Anesthesiologists to Improve Health Equity and Quality Measures Open
more likely to get delayed or did not receive care regardless of cost compared to heterosexuals. 3 As a specialty, anesthesiologists have researched several aspects of health disparities, including access to care and quality of care delive…

Contrast-enhanced Mammography-guided Biopsy: Initial Trial and Experience Open
Objective Evaluate lesion visibility and radiologist confidence during contrast-enhanced mammography (CEM)-guided biopsy. Methods Women with BI-RADS ≥4A enhancing breast lesions were prospectively recruited for 9-g vacuum-assisted CEM-guid…
Lateralization of Autonomic Output in Response to Limb-Specific Threat Open
In times of stress or danger, the autonomic nervous system (ANS) signals the fight or flight response. A canonical function of ANS activity is to globally mobilize metabolic resources, preparing the organism to respond to threat. Yet a bod…
Social drivers of maturation age in female geladas Open
Female reproductive maturation is a critical life-history milestone, initiating an individual’s reproductive career. Studies in social mammals have often focused on how variables related to nutrition influence maturation age in females. Ho…
Effects of climate variability on the demography of wild geladas Open
Nonhuman primates are an essential part of tropical biodiversity and play key roles in many ecosystem functions, processes, and services. However, the impact of climate variability on nonhuman primates, whether anthropogenic or otherwise, …
The early life microbiota mediates maternal effects on offspring growth in a nonhuman primate Open
Maternal parity can impact offspring growth, but the mechanisms driving this effect are unclear. Here, we test the hypothesis that vertically transmitted microbiota may be one potential mechanism. We analyzed 118 fecal and milk samples fro…
Humans’ Association of Emotion with Music: A Literature Review Open
This literature review aims to address the current state of research regarding the relationship between classical and other predominantly non-vocal music and human emotion.The specific focuses of this review are three-fold: first, the corr…

Maternal effects on early-life gut microbiome maturation in a wild nonhuman primate Open
Early-life gut microbial colonization is an important process shaping host physiology, immunity and long-term health outcomes in humans and other animals. However, our understanding of this dynamic process remains poorly investigated in wi…

High-altitude adaptation and incipient speciation in geladas Open
Survival at high altitude requires adapting to extreme conditions such as environmental hypoxia. To understand high-altitude adaptations in a primate, we assembled the genome of the gelada ( Theropithecus gelada ), an endemic Ethiopian mon…
The Goldilocks effect: female geladas in mid-sized groups have higher fitness Open
The cost–benefit ratio of group living is thought to vary with group size: individuals in ‘optimally sized’ groups should have higher fitness than individuals in groups that are either too large or too small. However, the relationship betw…
Early life gut microbiome dynamics mediate maternal effects on infant growth in vervet monkeys Open
Background Maternal parity is associated with variation in infant growth across mammals, but the mechanisms underlying this relationship are unclear. Given emerging links between growth and the microbiome, and the importance of maternal mi…
