BACKGROUND: As the group at high risk for sepsis is increasing with the aging of the population, physical activity (PA), which has beneficial effects on various diseases, needs to be considered as a personalized prevention strategy for sepsis without direct anti-sepsis drug. PURPOSE: To examine the association between the amount of PA (based on intensity, duration, and frequency) and the incidence rates of sepsis and mortality after sepsis. METHODS: This was a large-scale, retrospective, longitudinal cohort study using data from the Korean National Health Insurance Service and the biennial general health screening program...

PURPOSE: To evaluate the outcomes of fluoroscopic versus portable placement of peripherally inserted central catheters (PICCs) and central venous catheters (CVCs) in pediatric patients. MATERIALS AND METHODS: This is a single-center, retrospective review of 346 upper-extremity PICCs (286 fluoroscopic, 60 portable), mean age = 9.83 ± 5.58 years, 49.1% female; and 138 tunneled femoral CVCs (56 fluoroscopic, 82 portable), mean age = .23 ± .36 years, 57.0% female...

Heated effluent injection, cold hypolimnetic water inputs from dams, and extreme weather events can lead to unpredictable temperature fluctuations in natural waters, impacting fish performance and fitness. We hypothesized that fish exposed to such unpredictable fluctuations would exhibit weaker growth and enhanced thermal tolerance compared to predictable conditions. Qingbo (Spinibarbus sinensis) was selected as the experimental subject in this study. The qingbo were divided into a constant temperature group (C, 22 ± 0...

The American Inflation Reduction Act (IRA) of 2022 contains climate-related provisions that may have significant implications for cancer control and prevention. This commentary assesses the potential co-benefits of the IRA for cancer control efforts, specifically policies and programs to reduce carcinogen exposure via air quality monitoring and air pollution reduction. Allocations through the IRA for air quality improvement, paired with its environmental justice provisions, holds promise for advancing cancer prevention by targeting resources to communities most susceptible to environmental hazards...

BACKGROUD: Modelling discrete-time cause-specific hazards in the presence of competing events and non-proportional hazards is a challenging task in many domains. Survival analysis in longitudinal cohorts often requires such models; notably when the data is gathered at discrete points in time and the predicted events display complex dynamics. Current models often rely on strong assumptions of proportional hazards, that is rarely verified in practice; or do not handle sequential data in a meaningful way...

OBJECTIVE: In recent years, radar technology has been extensively utilized in contactless human behavior monitoring systems. The unique capabilities of ultra-wideband (UWB) radars compared to conventional radar technologies, due to time-of-flight measurements, present new untapped opportunities for in-depth monitoring of human movement during overground locomotion. This study aims to investigate the deployability of UWB radars in accurately capturing the gait patterns of healthy individuals with no known walking impairments...

The plans of international space agencies to return to the Moon and explore deep space, including Mars, highlight the challenges of human adaptation and stress the need for a thorough analysis of the factors that facilitate, limit and modify human performance under extreme environments. This study investigates the influence of partial gravity on behavioural (error rate and reaction time) and neuronal parameters (event-related potentials) through parabolic flights. Brain cortical activity was assessed using EEG from 18 participants who solved a neurocognitive task, consisting of a mental arithmetic task and an auditory oddball paradigm, during Earth (1G), Lunar (0...

Coastal seas are under increasing pressure from extreme weather events and sea level rise, resulting in impacts such as changing hydrodynamic conditions, coastal erosion, and marine heat waves. To monitor changes in coastal marine habitats, such as reefs and macrophytes meadows, which add to the resilience of our coasts, consistent, medium- to long-term seafloor observations are needed. This project aims to deliver repeated, high-frequency sonar surveys on a stationary seabed mooring of a specific target area over a period of up to several months...

Platelets are blood components produced in the bone marrow and are essential in forming blood clots. Thrombocytosis refers to a condition that causes the excess production of platelets in the body. When it develops as a reaction to an infection, trauma, or surgery, it is known as secondary or reactive thrombocytosis. Although thrombocytosis is typically a self-limiting disorder, it can frequently result in hemorrhagic or thrombotic events. Extreme thrombocytosis may trigger thrombotic events. Therefore, clinicians must be aware of the complications of thrombocytosis...

PURPOSE: The prognosis of patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) is extremely poor, and systemic therapy is currently the mainstream treatment. This study aimed to assess the efficacy and safety of lenvatinib combined with anti-PD-1 antibodies and transcatheter arterial chemoembolization (triple therapy) in patients with HCC and PVTT. MATERIALS AND METHODS: This retrospective multicenter study included patients with HCC and PVTT who received triple therapy, were aged between 18 and 75 years, classified as Child Pugh class A or B, and had at least one measurable lesion...

Typhoons and rainstorms (>250 mm/day) are extreme weather events changing hydrological characteristics and thus nitrogen (N) cycle in coastal waters. However, responses of N cycle to rainstorms and typhoons and their underlying mechanisms need to be elucidated. In this study, we conducted an analysis of a comparative dataset encompassing concentrations of nitrate (NO3 - ), ammonium (NH4 + ), dissolved oxygen (DO), chlorophyll a (Chl a), hydrological parameters, dual isotopic composition of NO3 - (δ15 N-NO3 - and δ18 O-NO3 - ) in Zhanjiang Bay during three distinct periods: the normal wet season, rainstorm, and typhoon periods...

OBJECTIVE: Lower extremity peripheral arterial disease (PAD) is a severe condition that increases the risk of major adverse cardiovascular events, major adverse limb events, and all cause mortality. This study aimed to investigate the mortality risk among females and males hospitalised for the first time due to lower extremity PAD. METHODS: Three cohorts of patients who were admitted for the first time due to lower extremity PAD in 2007 - 2010, 2011 - 2014, and 2015 - 2018 were constructed...

Caribbean small island developing states are becoming increasingly vulnerable to compounding disasters, prominently featuring climate-related hazards and pandemic diseases, which exacerbate existing barriers to cancer control in the region. We describe the complexities of cancer prevention and control efforts throughout the Caribbean small island developing states, including the unique challenges of people diagnosed with cancer in the region. We highlight potential solutions and strategies that concurrently address disaster adaptation and cancer control...

China, especially the densely populated North China region, experienced severe haze events in the past decade that concerned the public. Although the most extreme cases have been largely eliminated through recent mitigation measures, severe outdoor air pollution persists and its environmental impact needs to be understood. Severe indoor pollution draws less public attention due to the short visible distance indoors, but its public health impacts cannot be ignored. Herein, we assess the trends and impacts of severe outdoor and indoor air pollution in North China from 2014 to 2021...

PURPOSE OF REVIEW: Patients with lower extremity peripheral artery disease (PAD) are at high risk for major adverse cardiovascular events (MACE) and major adverse limb events (MALE). This manuscript will review the current evidence for medical therapy in patients with PAD according to different clinical features and the overall cardiovascular (CV) risk. RECENT FINDINGS: The management of PAD encompasses non-pharmacologic strategies, including lifestyle modification such as smoking cessation, supervised exercise, Mediterranean diet and weight loss as well as pharmacologic interventions, particularly for high risk patients...

Flash floods in mountainous regions like the Himalayas are considered to be common natural calamities. Their consequences often are more dangerous than any flood event in the plains. These hazards not only put human lives at threat but also cause economic deflation due to the loss of lands, properties, and agricultural production. Hence, assessing the impact of such hazards in the existing agricultural system is of utmost importance to understand the probable crop loss. In this paper, we studied the efficiency of the remotely sensed microwave data to map the croplands affected by the flash flood that occurred in July 2023 in Himachal Pradesh, a mountainous state in the Indian Himalayan Region...

While droughts predominantly induce immediate reductions in plant carbon uptake, they can also exert long-lasting effects on carbon fluxes through associated changes in leaf area, soil carbon, etc. Among other mechanisms, shifts in carbon allocation due to water stress can contribute to the legacy effects of drought on carbon fluxes. However, the magnitude and impact of these allocation shifts on carbon fluxes and pools remain poorly understood. Using data from a wet tropical flux tower site in French Guiana, we demonstrate that drought-induced carbon allocation shifts can be reliably inferred by assimilating Net Biosphere Exchange (NBE) and other observations within the CARbon DAta MOdel fraMework...

Neuronal ceroid lipofuscinosis type 2 (CLN2) disease is a rare, lysosomal storage disorder that causes pediatric onset neurodegenerative disease. It is characterized by mutations in the TPP1 gene. Symptoms begin between 2 and 4 years of age with loss of previously acquired motor, cognitive, and language abilities. Cerliponase alfa, a recombinant human TPP1 enzyme, is the only approved therapy. We report the first presymptomatic cerliponase alfa intraventricular treatment in a familial case of CLN2 related to a classical TPP1 variant...

BACKGROUND: Procedural sedation and analgesia (PSA) is a technique of administering sedatives to induce a state that allows the patient to tolerate painful procedures while maintaining cardiorespiratory function, a condition that is frequently desired prehospital. Non-physician prehospital clinicians often have a limited scope of practice when it comes to providing analgesia and sedation; sometimes resulting in a crew request for back-up from physician-staffed prehospital services.". This is also the case if sedation is desirable...

Estuaries are a significant source of nutrients to the marine environment. The magnitude of this source is a function of nutrients load reaching the estuary and removal (attenuation) within estuaries. Most estuarine research is conducted in large estuaries, which do not reflect the processes in small estuaries in urban and semi-arid regions where flood water is a substantial portion of the annual discharge and the estuarine baseflow is often low and dominated by wastewater. To improve the understanding of nutrient attenuation and load into the Mediterranean, we conducted high-resolution nutrient sampling in the eutrophic Alexander micro-estuary as a test case...
