INTRODUCTION: The risks and benefits of including an arthroscopic subacromial decompression (ASD) during arthroscopic rotator cuff repair (RCR) are uncertain. Some studies suggest no difference in revision surgery rates, whereas others have found higher revision surgery rates associated with concomitant ASD. In this study, we compare mid-term revision surgery rates in patients undergoing arthroscopic RCR with or without concomitant ASD. METHODS: A retrospective cohort analysis was conducted using a national all-payer claims database...

High-energy-density lithium metal batteries (LMBs) are confronted with crucial concerns of security and a short cycle lifespan caused by the uncontrollable formation of lithium (Li) dendrites. The poor thermal stability and heterogeneous Li deposition of conventional polyolefin separators often cause battery short circuiting and thermal runaway in LMBs. Herein, a novel dual-functional PE composite separator (PI-COOH/PE) coated by carboxyl polyimide (PI) microspheres is fabricated by an etching-acidification method...

Long COVID is a term used to describe the long-terms effects of COVID-19 infection that continue for weeks or months after the patient has recovered from COVID-19. Long COVID is defined by the persistence of symptoms beyond 12 weeks from the onset of the disease. Corticosteroids are part of the treatment in this period with good results in controlling the disease; however, it is a predisposing factor for the development of avascular necrosis. We present a clinic case of a young man of 39 years old with diagnosis of avascular necrosis in his left hip, before the administration of corticosteroids for the treatment of COVID-19...

INTRODUCTION: health promotion policy requires the identification of barriers to the adoption of public policies. Paraguay's national healthcare system is inequitable, expensive, and inefficient. The Ministry of Public Health and Social Welfare (MSPyBS) is the entity responsible for covering the needs of a significant portion of the population. In January 2022, the MSPyBS financed the purchase of titanium elastic nails through a National Public Tender for Osteosynthesis Materials (LPN 02/22) to provide them for free in the pediatric service...

BACKGROUND: Early childhood education services (ECE) continue to be a key setting to promote physical activity and limit sedentary behaviour. Thus, the aim of this study was to (1) provide an updated systematic review of correlates of physical activity and sedentary behaviour among children in ECE settings and (2) discuss changes in physical activity and sedentary behaviour correlates among children in ECEC settings over time. METHODS: A systematic search of eight databases identified 40 studies published between 2015 and 2023 that met the inclusion criteria...

Plants continuously remodel and degrade their organelles due to damage from their metabolic activities and environmental stressors, as well as an integral part of their cell differentiation programs. Whereas certain organelles use local hydrolytic enzymes for limited remodeling, most of pathways that control the partial or complete dismantling of organelles rely on vacuolar degradation. Specifically, selective autophagic pathways play a crucial role in recognizing and sorting plant organelle cargo for vacuolar clearance, especially under cellular stress conditions induced by factors like heat, drought, and damaging light...

Hydrogen sulfide (H2 S), a critical gas signaling molecule, and N -acetyltransferase 2 (NAT2), a key enzyme in drug metabolism, are both known active biomarkers for liver function. However, the interactions and effects of H2 S and NAT2 in living cells or lesion sites remain unknown due to the lack of imaging tools to achieve simultaneous detection of these two substances, making it challenging to implement real-time imaging and precise tracking. Herein, we report an activity-based two-photon fluorescent probe, TPSP-1 , for the cascade detection of H2 S and NAT2 in living liver cells...

The hydrologic cycle has wide impacts on the ocean salinity and circulation, carbon and nitrogen cycles, and the ecosystem. Under anthropogenic global warming, previous studies showed that the intensification of the hydrologic cycle is a robust feature. Whether this trend persists in hothouse climates, however, is unknown. Here, we show in climate models that mean precipitation first increases with rising surface temperature, but the precipitation trend reverses when the surface is hotter than ~320 to 330 kelvin...

Many pathogens continuously change their protein structure in response to immune-driven selection, resulting in weakened protection even in previously exposed individuals. In addition, for some pathogens, such as dengue virus, poorly targeted immunity is associated with increased risk of severe disease through a mechanism known as antibody-dependent enhancement. However, it remains unclear whether the antigenic distances between an individual's first infection and subsequent exposures dictate disease risk, explaining the observed large-scale differences in dengue hospitalizations across years...

Genomes contain conserved non-coding sequences that perform important biological functions, such as gene regulation. We present a phylogenetic method, PhyloAcc-C, that associates nucleotide substitution rates with changes in a continuous trait of interest. The method takes as input a multiple sequence alignment of conserved elements, continuous trait data observed in extant species, and a background phylogeny and substitution process. Gibbs sampling is used to assign rate categories (background, conserved, accelerated) to lineages and explore whether the assigned rate categories are associated with increases or decreases in the rate of trait evolution...

High-power LED lighting is a crucial challenge due to the notorious thermal quenching (TQ) effect of traditional phosphors at high operating currents, which would result in poor device performance and hamper practical optoelectronic application. Herein, we demonstrate ligand engineering of a cubane- versus staircase-like [Cu4 I4 ] conformer as a node in coordination polymers, which remarkably suppresses the TQ effect of cluster-based photoluminescence. For complex 1 (the formula [Cu4 I4 (bbimb)2 ] n ) with the cubane-like [Cu4 I4 ] conformer as a node, the metallophilicity interaction enables ultrabright triplet emission with a photoluminescence quantum yield over 82%, and the phonon-assisted detrapping process of excitons effectively suppresses the TQ effect in the wide temperature range...

Unidirectional photochemically driven molecular motors (PMMs) convert the energy of absorbed light into continuous rotational motion. As such they are key components in the design of molecular machines. The prototypical and most widely employed class of PMMs is the overcrowded alkenes, where rotational motion is driven by successive photoisomerization and thermal helix inversion steps. The efficiency of such PMMs depends upon the speed of rotation, determined by the rate of ground state thermal helix inversion, and the quantum yield of photoisomerization, which is dependent on the excited state energy landscape...

Natural language use is a promising candidate for the development of innovative measures of well-being to complement self-report measures. The type of words individuals use can reveal important psychological processes that underlie well-being across the lifespan. In this preregistered, cross-sectional study, we propose a conceptual model of language markers of well-being and use written narratives about healthy aging (N = 701) and computerized text analysis (LIWC) to empirically validate the model. As hypothesized, we identified a model with three groups of language markers (reflecting affective, evaluative, and social processes)...

Patients with single ventricle continue to be a challenge for heart transplantation (HTx). A poor clinical condition, previous multiple surgical procedures, and possible allosensitization lead to an increased risk of complications. The results have improved in recent series (1). However, patients with preserved ventricular function continues to have a higher rate of mortality (2). Additionally, there are often anatomical alterations of the pulmonary arteries that complicate the surgery (1,3). This report presents a case of tricuspid atresia with pulmonary preassures that contraindicated Fontan surgery, with unfavorable anatomy of the central PAs and a poor clinical situation, in which an EXCOR® VAD (Berlin Heart) was used for subpulmonary mechanical circulatory support (MCS), associated with pulmonary bifurcation reconstruction, as a bridge to HTx...

OBJECTIVE: Excess mortality has been demonstrated in patients with systemic lupus erythematosus (SLE) compared with the general population. We aimed to investigate the 5-year and 10-year all-cause mortality in patients with SLE compared with the general population in recent decades. METHODS: Nationwide population-based exposure matched cohort study. Incident cases of SLE diagnosed between 1996 and 2015 were identified using administrative health registries and followed until 2020, allowing for 5 and 10 years of follow-up...

BACKGROUND: The burden of multidrug-resistant bacterial infections in low-income countries is alarming. This study aimed to identify the bacterial etiologies and antibiotic resistance patterns among neonates in Jimma, Ethiopia. METHODS: An observational longitudinal study was conducted among 238 presumptive neonatal sepsis cases tested with blood and/or cerebrospinal fluid culture. The bacterial etiologies were confirmed using matrix-assisted laser desorption ionization-time of flight mass spectrometry...

BACKGROUND Cytosolic phosphoenolpyruvate carboxykinase (PEPCK-C) deficiency is an extremely rare autosomal recessive inherited error of metabolism in which gluconeogenesis is impaired, resulting in life-threatening episodes of hypoglycemia and metabolic acidosis. The diagnosis of gluconeogenesis disorders is challenging. In the diagnostic pathway, the molecular test plays a paramount role. CASE REPORT The aim of the paper is to present the case report of a girl with recurrent episodes of severe hypoglycemia, in whom molecular diagnosis enabled the confirmation of PEPCK - C deficiency...

Intersectionality has facilitated an understanding of the complexities of the adversities and challenges faced by individuals with multiple disadvantaged identities, including gay and bisexual men living with HIV. This study used deficiency- and empowerment-based perspectives together with an intersectionality lens to examine the intersections between sexuality minority and HIV-related stigma and resilience, as well as their compound effects on Chinese gay and bisexual men living with HIV. We conducted in-depth interviews with 21 gay and bisexual men living with HIV in Shenzhen, identifying two overarching themes and six subthemes in the provided accounts via thematic analysis...
