Landscape-level human disturbance results in loss and contraction of mammalian populations in tropical forests.

Tropical forests hold most of Earth's biodiversity and a higher concentration of threatened mammals than other biomes. As a result, some mammal species persist almost exclusively in protected areas, often within extensively transformed and heavily populated landscapes. Other species depend on remaining remote forested areas with sparse human populations.

Subsistence hunting impacts wildlife assemblages and functional ecology in tropical forests.

Unsustainable wild meat hunting poses a significant threat to wildlife and tropical forest ecosystems. While high levels of extraction linked to commercial trade have received significant attention, the sustainability of subsistence hunting by Indigenous Peoples in Africa has been less studied. Understanding how changing lifestyles, particularly the sedentarisation of former hunter-gatherers, have affected the use of forest resources is crucial for wildlife conservation and livelihoods.

Congenital Riedel's lobe of the liver: A case report.

Riedel's lobe of the liver is a rare anatomical variant often incidentally found on imaging or through the presence of hepatomegaly on physical examination. While patients are usually asymptomatic, the presentation of this condition can vary, ranging from nonspecific symptoms to more severe issues such as torsion, obstruction, rupture, and bleeding. We present a case of a patient with asymptomatic hepatomegaly who was incidentally found to have Riedel's lobe of the liver, accompanied by an elevated IgG mitochondrial antibody.

Leopard density and the ecological and anthropogenic factors influencing density in a mixed-use landscape in the Western Cape, South Africa.

Large carnivores face numerous threats, including habitat loss and fragmentation, direct killing, and prey depletion, leading to significant global range and population declines. Despite such threats, leopards (Panthera pardus) persist outside protected areas throughout most of their range, occupying diverse habitat types and land uses, including peri-urban and rural areas. Understanding of leopard population dynamics in mixed-use landscapes is limited, especially in South Africa, where the majority of leopard research has focused on protected areas.

Characteristics and Outcomes of Cancer Patients With Venous Thromboembolic Events After Treatment With Immune Checkpoint Inhibitors.

Objective: This study aimed to describe the clinical characteristics and outcomes of patients with venous thromboembolism (VTE) after Immune checkpoint inhibitors (ICI), focusing on patients with gastrointestinal (GI) immune-related adverse events (irAE).

Methods: In this retrospective, single-center study, we report the clinical outcomes of adult cancer patients who developed a VTE within 2 years of ICI initiation. Patients were excluded if alternate causes of VTE were present apart from malignancy and cancer therapy.

Acute liver injury and IgG4-related autoimmune pancreatitis following mRNA-based COVID-19 vaccination.

IgG4-related disease (IgG4-RD) is a fibro-inflammatory disease that can affect multiple organs. Autoimmune pancreatitis type 1 is a manifestation of IgG4-RD and can often mimic tumor-like masses. Autoimmune phenomena following COVID-19 mRNA vaccination are being increasingly reported.

Cytomegalovirus infection among patients with cancer receiving immune checkpoint inhibitors.

Background: Immune checkpoint inhibitors (ICIs), used for the treatment of solid and hematologic malignancies, come with the risk of immune-related adverse events (irAEs). Opportunistic infections (e.g.

Immune checkpoint inhibitor-related gastrointestinal toxicity in patients with malignancy involving the luminal gastrointestinal tract and its impact on cancer outcomes.

Background: Immune checkpoint inhibitors (ICI) are known to cause immune-related adverse events (irAE) with the gastrointestinal (GI) tract among the most affected. Our knowledge of GI irAE in patients with luminal GI malignancies is poor. We aimed to characterize the incidence, clinical features, treatment, and outcomes of these GI irAEs.

Clinical characteristics and outcomes of tyrosine kinase inhibitor-related lower GI adverse effects.

Purpose: A variety of tyrosine kinase inhibitors (TKIs) are currently approved for the treatment of solid tumors and hematological cancers. However, TKIs are often associated with gastrointestinal (GI) adverse effects (AEs), especially diarrhea. Therefore, in the present study, we aimed to describe the clinical features and outcomes of TKI-associated lower GI AEs.

Laying low: Rugged lowland rainforest preferred by feral cats in the Australian Wet Tropics.

Invasive mesopredators are responsible for the decline of many species of native mammals worldwide. Feral cats have been causally linked to multiple extinctions of Australian mammals since European colonization. While feral cats are found throughout Australia, most research has been undertaken in arid habitats, thus there is a limited understanding of feral cat distribution, abundance, and ecology in Australian tropical rainforests.

infection in cancer patients receiving immune checkpoint inhibitors.

Background: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, but are associated with immune-mediated diarrhea and colitis (IMDC). infection (CDI) can cause infectious diarrhea with overlapping symptoms. Thus, we sought to elucidate the characteristics of CDI in patients treated with ICI, in the context of IMDC.

Population size, density, and ranging behaviour in a key leopard population in the Western Cape, South Africa.

Globally, leopards are the most widespread large felid. However, mounting anthropogenic threats are rapidly reducing viable leopard populations and their range. Despite the clear pressures facing this species, there is a dearth of robust and reliable population and density estimates for leopards across their range, which is particularly important in landscapes that consist of protected and non-protected areas.

The Role of Race, Sex, and Age in Circadian Disruption and Metabolic Disorders.

Circadian rhythms are 24-hour internal biological cycles that play an important role in metabolism, and their disruption has been implicated in the development of diseases such as diabetes mellitus type 2, obesity, coronary artery disease, hypertension, and metabolic syndrome. This phenomenon is illustrated by increased rates of risk factors for cardiovascular disease in night shift workers. Race, sex, and age are factors that play a role in circadian rhythms and metabolic disorders.

Patterns and determinants of elephant attacks on humans in Nepal.

Attacks on humans by Asian elephant () is an extreme form of human-elephant conflict. It is a serious issue in southern lowland Nepal where elephant-related human fatalities are higher than other wildlife. Detailed understanding of elephant attacks on humans in Nepal is still lacking, hindering to devising appropriate strategies for human-elephant conflict mitigation.

Clinicopathologic Features, Treatment Response, and Outcomes of Immune Checkpoint Inhibitor-Related Esophagitis.

Background: Although immune checkpoint inhibitors (ICIs) have provided practice-changing outcomes in treating many cancers, ICI-related gastrointestinal toxicity can limit their use. Upper gastrointestinal toxicity is not common nor as well described as lower gastrointestinal toxicity. We aimed to characterize the clinical presentation, endoscopic and histologic features, treatment response, and outcomes of ICI-related esophagitis.

A new subspecies of giant sengi (Macroscelidea: Rhynchocyon) from coastal Kenya.

A new subspecies of giant sengi or elephant-shrew, first documented in 2008, is described from northern coastal Kenya. All five currently described species and most known subspecies of Rhynchocyon are compared to this new lineage. Molecular analyses using mitochondrial and nuclear markers from the single DNA sample available for the new lineage show differences from other forms and reveal a close relationship with the allopatric golden-rumped sengi R.

Analysis of payments to GI physicians in the United States: Open payments data study.

Background And Aim: The purpose of this study was to review and analyze the nature of industry payments to gastroenterology and hepatology (GI) physicians.

Methods: We conducted a retrospective study of open payments (OP) data for the year 2017. Payments to individual physicians were aggregated using a unique physician profile identification number.

Software to facilitate and streamline camera trap data management: A review.

Improving technology and increasing affordability mean that camera trapping-the use of remotely triggered cameras to photograph wildlife-is becoming an increasingly common tool in the monitoring and conservation of wild populations. Each camera trap study generates a vast amount of data, which need to be processed and labeled before analysis. Traditionally, processing camera trap data has been performed manually by entering data into a spreadsheet.

Polypectomy versus surgery in early colon cancer: size and location of colon cancer affect long-term survival.

Background And Aims: The colon cancer survival rate is significantly affected by location, stage, and size of the cancer. Polypectomy was shown be as equally effective as surgery in early-stage colon cancer, but there have been no established clinical guidelines in the management of colon cancer based on the size of the polyp or the tumor location. The aim of our study was to assess the early-stage colon cancer-specific survival rate in patients who underwent endoscopic polypectomy versus surgery, based on size and location of tumor in early-stage colon cancer.

Early Esophageal Cancer Specific Survival Is Unaffected by Anatomical Location of Tumor: A Population-Based Study.

Background. Approximately one-fifth of all esophageal cancer cases are defined as early esophageal cancer (EEC). Although endoscopic therapy (ET) has been shown to be equally effective as esophagectomy (EST) in patients with EEC, there is little information comparing the survival outcomes of the two therapies based on anatomical location.

Three-year results of a multicenter prospective study of transoral incisionless fundoplication.

Background: To date, there are no long-term data on the use of transoral incisionless fundoplication (TIF) for the treatment of chronic gastroesophageal reflux disease (GERD). We sought to prospectively evaluate the long-term safety and durability of TIF in a multi-center setting.

Methods: A longitudinal per protocol (PP) and a modified intention-to-treat (mITT) analysis at 1 and 3 years consisted of symptom evaluation using the GERD health-related quality of life (GERD-HRQL) questionnaire, medication use, upper gastrointestinal endoscopy, and pH-metry.

Remotely-sensed active fire data for protected area management: eight-year patterns in the Manas National Park, India.

The Terai-Duar savanna and grasslands, which once extended along most of the Himalayan foothills, now only remain in a number of protected areas. Within these localities, grassland burning is a major issue, but data on frequency and distribution of fires are limited. Here, we analysed the incidence of active fires, which only occur during the dry season (Nov.
